Tar sand  

SciTech Connect (OSTI)

Research on tar sand is briefly discussed. The research program supported by the US Department of Energy (DOE) includes a variety of surface extraction schemes. The University of Utah has process development units (PDU) employing fluidized bed, hot, water-assisted, and fluidized-bed/heat-pipe, coupled combustor technology. Considerable process variable test data have been gathered on these systems: (1) a rotary kiln unit has been built recently; (2) solvent extraction processing is being examined; and (3) an advanced hydrogenation upgrading scheme (hydropyrolysis) has been developed. The University of Arkansas, in collaboration with Diversified Petroleum, Inc., has been working on a fatty acid, solvent extraction process. Oleic acid is the solvent/surfactant. Solvent is recovered by adjusting processing fluid concentrations to separate without expensive operations. Western Research Institute has a PDU-scale scheme called the Recycle Oil Pyrolysis and Extraction (ROPE) process, which combines solvent (hot recycle bitumen) and pyrolytic extraction. 14 refs., 19 figs.

Solvent extraction of southern US tar sands  

SciTech Connect (OSTI)

The socioeconomic aspects of the tar sands recovery were investigated by Diversified Petroleum Recovery, Inc. Mineral Resources Institute at the University of Alabama conducted characterization and beneficiation studies on Alabama tar sands. Two sources in the state were identified, namely, Black Wax Hill and Spring Creek. Samples were obtained, beneficiated, then shared with the University of Arkansas. The University of Arkansas conducted research in three areas, namely, solvation and characterization of the tar sands phase equilibria as well as the design and operation of a bench-scale batch model. In the solvation studies, the results indicate that grinding the tar sands too fine results in downstream processing problems. Also, preliminary indications are that the beneficiation step may not be necessary in the solvation of the bitumen. The phase equilibria of the heptane/brine/isopropyl alcohol/XTOL{trademark} system is very complex. The salt concentration of the brine is significant in the partitioning of the isopropanol and heptane. Equilibrium data for some of the various combinations of chemical constituents have been obtained. Also included are appendices: statistical data on highways; petrography; Dean-Starke technique; FTIR and NMR spectra; FORTRAN computer program for GC; simulation of flash behavior for IPA/brine/fatty acid/N-C{sub 7} mixture; and previous progress reports. 32 figs., 28 tabs.

The potential use of tar sand bitumen as paving asphalt  

SciTech Connect (OSTI)

The properties of several tar sand asphalts prepared in past studies by several different investigators were compared with each other and with the properties of petroleum asphalts. These results were reviewed and discussed with regard to the potential use of tar sand bitumen in pavement applications. The data show that tar sand bitumen has good potential for use in highway pavements that meet today's performance specifications. No deficiencies in the tar sand asphalts were found that would be expected to seriously affect performance. On the other hand, the data indicate that some tar sand asphalts may have superior aging characteristics, being relatively resistant to oxidative age hardening compared with typical petroleum asphalts. Asphalt-aggregate mixtures prepared using two tar sand asphalts also showed acceptable strength properties and excellent resistance to moisture-induced damage.

Solvent extraction of Southern US tar sands  

SciTech Connect (OSTI)

The Department of Chemical Engineering at the University of Arkansas, in association with Diversified Petroleum Recovery, Inc. (DPR) of Little Rock, Arkansas, has been developing a solvent extraction process for the recovery of bitumen from tar sands for the past five years. The unique feature of the process is that the bitumen is recovered from the solvent by contacting with a co-solvent, which causes the bitumen to precipitate. The overall purpose of this project is to study both the technical and economic feasibility of applying this technology for recovery of bitumen from tar sands by (1) investigating the socioeconmic factors which affect (a) plant siting and (b) the market value of recovered bitumen; (2) operating a process demonstration unit at the rate of 1 lb/hr recovered bitumen while producing clean sand and recyclable solvents; and (3) determine the economic conditions which will make a bitumen recovery project economical. DPR has analyzed the historical trends of domestic production, consumption, discoveries and reserves of crude oil. They have started an investigation of the volatility in the price of crude oil and of gasoline prices and of the differential between gasoline and crude oil. DPR continues to analyze the geographical movement and demand for asphalt products. Utah does not appear economically attractive as a site for a bitumen from tar sands asphalt plant. Oklahoma sites are now being studied. This report also contains the quarterly progress report from a University of Nevada study to determine bitumen composition, oxygen uptake rates, and viscosities of Alabama and Utah bitumens. Both reports have been indexed separately for inclusion on the data base.

Process for upgrading tar sand bitumen  

SciTech Connect (OSTI)

A process is described for upgrading a charge of a tar sand bitumen concentrate containing mineral matter including fine particles which comprises contacting the charge in a riser in the presence of a low boiling organic solvent diluent with finely divided attrition-resistant particles of a hot fluidizable substantially catalytically inert solid which is substantially chemically inert to a solution of mineral acid. The contact of the charge with the particles is at high temperature and short contact time to vaporize the high hydrogen containing components of the bitumen, the period of time being less than that which induces substantial thermal cracking of the charge, at the end of the time separating the vaporizing product from the fluidizable particles. The fluidizable particles now bear a deposit of both combustible solid, adherent particles of fine particles of mineral matter and metals. The particles of inert solid are passed with deposit of combustibles and fine particles of mineral matter to a regenerator to oxidize the combustible portion of the deposits, removing at least a portion of deposit of mineral matter and metals by removing the inert solid from the regenerator and contacting removed inert solid with a hot mineral acid, and recirculating fluidizable solid depleted at least in part of deposited mineral matter to contact with incoming charge of tar sand bitumen concentrate and diluent.

Solvent extraction of bitumen from tar sands  

SciTech Connect (OSTI)

This paper reports on the measurement of mass transfer rates for the extraction of bitumen from tar sands using organic solvents. The experiment was carried out in an agitated vessel using a six-blade turbine mixer on a laboratory scale. To facilitate the determination of absolute mass transfer coefficients, tar sands were specially prepared in the form of spherical particles so that mass transfer area can be computed. The variables investigated in the study included: (1) solvent type (kerosene, toluene, benzene), (2) stirrer speed, 25 rpm to 1000 rpm, and (3) particle diameter, 0.4 cm to 1.2 cm. The results indicated that solvency power varied markedly with the various solvents used and that high aromatic content promoted rapid dissolution when compared with paraffinic solvents. The mass transfer rates increased with increasing stirrer speed in accordance with the relationship: k {alpha} N{sup 0.56} where k is the mass transfer coefficient and N the stirrer speed. Increasing particle diameter also resulted in decreased mass transfer rates. The results were satisfactorily correlated in terms of a Frossling type equation, Sh {alpha} Re{sub p}{sup a}Sc{sup b}.

Method and apparatus for hydrocarbon recovery from tar sands  

DOE Patents [OSTI]

A method and apparatus for utilizing tar sands having a broad range of bitumen content is disclosed. More particularly, tar sands are pyrolyzed in a cyclone retort with high temperature gases recycled from the cyclone retort to produce oil and hydrocarbon products. The spent tar sands are then burned at 2000/degree/F in a burner to remove residual char and produce a solid waste that is easily disposable. The process and apparatus have the advantages of being able to utilize tar sands having a broad range of bitumen content and the advantage of producing product gases that are free from combustion gases and thereby have a higher heating value. Another important advantage is rapid pyrolysis of the tar sands in the cyclone so as to effectively utilize smaller sized reactor vessels for reducing capitol and operating costs. 1 fig., 1 tab.

Heats of dissolution of tar sand bitumen in various solvents  

SciTech Connect (OSTI)

The dissolution of tar sand bitumen from a tar sand matrix was examined using three solvents: (1) dichloromethane, a polar-polarizable solvent; (2) toluene, a nonpolar-polarizable solvent; and (3) hexane, a nonpolar-nonpolarizable solvent. The dichloromethane had the highest dissolution energy, followed by toluene, with hexane having the lowest dissolution energy. These data were combined with heat of dissolution of recovered bitumen and heat of wetting of spent sand to calculate the bonding energy between bitumen and the mineral matrix. The interfacial bonding energy between tar sand bitumen and the mineral matrix was found to be in the region of 0 to 0.09 cal/g of bitumen, which is very small. This conclusion may find application in recovery of energy or bitumen from bitumen-wet tar sand deposits. 9 refs., 2 tabs.

The potential use of tar sand bitumen as paving asphalt  

SciTech Connect (OSTI)

In this paper several research reports describing the preparation of potential paving asphalts from tar sand bitumen are reviewed and the results of the studies compared. The tar sand asphalts described in the studies were prepared from 1) hot water-recovered bitumen from deposits near San Luis Obispo, California (Edna deposits), and deposits near Vernal and Sunnyside, Utah; and 2) bitumen recovered from the Northwest Asphalt Ridge deposits near Vernal, Utah, by both in situ steamflood and in situ combustion recovery processes. Important properties of the tar sand asphalts compare favorably with those of specification petroleum asphalts. Laboratory data suggest that some tar sand asphalts may have superior aging characteristics and produce more water-resistant paving mixtures than typical petroleum asphalts.

An evaluation of the potential end uses of a Utah tar sand bitumen. [Tar sand distillate  

SciTech Connect (OSTI)

To date the commercial application of tar sand deposits in the United States has been limited to their use as paving materials for county roads, parking lots, and driveways because the material, as obtained from the quarries, does not meet federal highway specifications. The bitumen in these deposits has also been the subject of upgrading and refining studies to produce transportation fuels, but the results have not been encouraging from an economic standpoint. The conversion of tar sand bitumen to transportation fuels cannot compete with crude oil refining. The purposes of this study were two-fold. The first was to produce vacuum distillation residues and determine if their properties met ASTM asphalt specifications. The second was to determine if the distillates could serve as potential feedstocks for the production of aviation turbine fuels. The bitumen used for this study was the oil produced during an in situ steamflood project at the Northwest Asphalt Ridge (Utah) tar sand deposit. Two distillation residues were produced, one at +316/sup 0/C and one at +399/sup 0/C. However, only the lower boiling residue met ASTM specifications, in this case as an AC-30 asphalt. The original oil sample met specifications as an AC-5 asphalt. These residue samples showed some unique properties in the area of aging; however, these properties need to be investigated further to determine the implications. It was also suggested that the low aging indexes and high flow properties of the asphalts may be beneficial for pavements that require good low-temperature performance. Two distillate samples were produced, one at IBP-316/sup 0/C and one at IBP-399/sup 0/C. The chemical and physical properties of these samples were determined, and it was concluded that both samples appear to be potential feedstocks for the production of aviation turbine fuels. However, hydrogenation studies need to be conducted and the properties of the finished fuels determined to verify the prediction. 14 refs., 12 tabs.

Process for upgrading tar sand bitumen  

SciTech Connect (OSTI)

A process is described for upgrading a charge of a tar sand bitumen concentrate containing metal impurities, colloidal calcium-containing clay and water. It consists of contacting the charge in a riser contacting zone in the presence of a low boiling organic solvent with hot fluidizable attrition-resistant substantially catalytically-inert microspheres, which are 20 to 150 microns in diameter and are composed of previously calcined kaolin clay. The contact takes place at high temperature and short contact time, which permits vaporization of the high hydrogen containing components of the bitumen. The period of time is less than that which induces substantial thermal cracking of the charge. At the end of the time the vaporized produce is separated from the microspheres of calcined kaolin clay, the microspheres of calcined kaolin clay now bearing a deposit of combustible solid, metal impurities and adherent particles of colloidal calcium-containing clay originally contained in the bitumen concentrate, immediately reducing the temperature of the vaporized product to minimize thermal cracking and recovering the product for further refining to produce one or more premium products.

The extraction of bitumen from western tar sands  

SciTech Connect (OSTI)

This report represents the work done during the year of May 8, 1987 to June 9, 1988. This year was the first year of a five-year program. The overall objective of the latter is to advance the technologies for recovering bitumen from the tar sands by thermal and water assisted extraction means and upgrading of bitumen to synthetic crude, and conversion of bitumens to specialty products such as asphalt and resins to levels where realistic evaluations of technical and commercial potential can be made. Additionally, it is desired to have the data at a level which is adequate for design of pilot plants of appropriate size deemed necessary for commercial scale-up of the various processes being studied. The main areas for studies covered in this report are modelling and optimization of the hydropyrolysis process for upgrading bitumens, bitumen recovery by pyrolysis of the circle Cliffs tar sands in a fluid bed, pyrolysis of Whiterocks tar sand in a rotary kiln, modelling of the combustor in the coupled fluidized bed with interbed heat transfer using heat pipes, development of superior diluents for use in the water extraction of Utah's tar sands, and fractionation and characterization of the bitumens from Asphalt Ridge and Sunnyside tar sands. 169 refs., 60 figs., 31 tars.

The declining quality of petroleum is a particular problem for aviation turbine fuels. Since these fuels are required to meet stringent corrosion, thermal stability and purity specification, very little in the way of contaminants or heteroatoms can be tolerated. However, heavier and more sour crude supplied result in lower straight-run turbine fuel yields, higher sulfur contents, and higher aromatic contents. While all turbine fuels were originally prepared from high quality stocks by distillation, many commercial and military fuels now require hydrotreatment to meet specifications. The work described in this program extrapolates these present trends to very heavy feedstocks. Tar sands bitumen and heavy crude oils are low API gravity, high viscosity hydrocarbonaceous materials commonly exhibiting high levels of heteroatomic species, high metals content and high levels of asphaltenes, plus water and solids not readily separated by conventional technology without dilution. Tar sands bitumen is highly cyclic with many polycyclic rings and naphthenic constituents. Sulfur is primarily in thiophenic structures, with nitrogen included in the ring structure. Asphaltenes are in high proportion, with a large amount of sulfur, nitrogen and metallic inclusions. Each of these characteristics represent specific concerns to refiners.

Production of bitumen-derived hydrocarbon liquids from Utah's tar sands: Final report  

SciTech Connect (OSTI)

In previous work done on Utah's tar sands, it had been shown that the fluidized-bed pyrolysis of the sands to produce a bitumen-derived hydrocarbon liquid was feasible. The research and development work conducted in the small-scale equipment utilized as feed a number of samples from the various tar sand deposits of Utah elsewhere. The results from these studies in yields and quality of products and the operating experience gained strongly suggested that larger scale operation was in order to advance this technology. Accordingly, funding was obtained from the State of Utah through Mineral Leasing Funds administered by the College of Mines and Earth Sciences of the University of Utah to design and build a 4-1/2 inch diameter fluidized-bed pilot plant reactor with the necessary feeding and recovery equipment. This report covers the calibration and testing studies carried out on this equipment. The tests conducted with the Circle Cliffs tar sand ore gave good results. The equipment was found to operate as expected with this lean tar sand (less than 5% bitumen saturation). The hydrocarbon liquid yield with the Circle Cliffs tar sand was found to be greater in the pilot plant than it was in the small unit at comparable conditions. Following this work, the program called for an extensive run to be carried out on tar sands obtained from a large representative tar sand deposit to produce barrel quantities of liquid product. 10 refs., 45 figs., 11 tabs.

Paleontological overview of oil shale and tar sands areas in Colorado, Utah, and Wyoming.  

SciTech Connect (OSTI)

In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the ''Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005,'' Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. In addition, Congress declared that both research- and commercial-scale development of oil shale and tar sands should (1) be conducted in an environmentally sound manner using management practices that will minimize potential impacts, (2) occur with an emphasis on sustainability, and (3) benefit the United States while taking into account concerns of the affected states and communities. To support this declaration of policy, Congress directed the Secretary of the Interior to undertake a series of steps, several of which are directly related to the development of a commercial leasing program for oil shale and tar sands. One of these steps was the completion of a programmatic environmental impact statement (PEIS) to analyze the impacts of a commercial leasing program for oil shale and tar sands resources on public lands, with an emphasis on the most geologically prospective lands in Colorado, Utah, and Wyoming. For oil shale, the scope of the PEIS analysis includes public lands within the Green River, Washakie, Uinta, and Piceance Creek Basins. For tar sands, the scope includes Special Tar Sand Areas (STSAs) located in Utah. This paleontological resources overview report was prepared in support of the Oil Shale and Tar Sands Resource Management Plan Amendments to Address Land Use Allocations in Colorado, Utah, and Wyoming and PEIS, and it is intended to be used by Bureau of Land Management (BLM) regional paleontologists and field office staff to support future projectspecific analyses.

Characterization and potential utilization of Whiterocks (Utah) tar sand bitumen  

SciTech Connect (OSTI)

This paper reports on the native Whiterocks (Utah) tar sand bitumen that was separated into several boiling range fractions for detailed analysis and characterization. The lighter fraction (477-617 K) was evaluated for use as a transportation fuel and the residues ({gt}617 K and {gt}728 K) were evaluated for use as road asphalts. The 617 K plus residue from the Whiterocks bitumen can be classified as a viscosity grade AC-10 asphalt whereas the 728 K plus residue failed to meet asphalt specifications. Apart from the asphalt specification tests, several sophisticated techniques were used to characterize these fractions. The detailed structure of the low molecular weight portions of Whiterocks bitumen (477-617 K and 617-728 K) was determined by combined GC-MS. Several physical properties were also measured to evaluate the potential of the 477-617 K fraction as a high density/energy aviation turbine fuel. This lower molecular weight fraction of the bitumen contained predominantly naphthenic hydrocarbons and lesser concentrations of aromatic hydrocarbons. This was confirmed by the FTIR spectra and by the GC-MS analyses. As a result, the 477-617 K fraction appeared to be an excellent candidate as a feedstock for the production of high density, aviation turbine fuels following mild hydrotreating.

Catalyst poisoning during tar-sands bitumen upgrading  

SciTech Connect (OSTI)

A number of hydrotreating catalysts are used in commercial heavy oil upgrading facilities. One of these, a CoO/MoO{sub 3}/Al{sub 2}O{sub 3} catalyst has been evaluated in a pilot plant CSTR for Tar-Sands Bitumen upgrading. Following its use in a test of 200 hours duration, the catalyst was removed, de-oiled, regenerated by air-calcination to remove the coke, and then re-tested. Samples of the coked, fresh and regenerated catalyst were each examined using surface analytical techniques. ESCA and SIMS analysis of the coked and regenerated catalyst samples show, as expected, significant contamination of the catalyst with Ni and V. In addition, the SIMS analysis clearly reveals that the edges of the catalyst pellets are rich in Ca, Mg and Fe while the Ni, V and coke are evenly distributed. Regeneration of the catalyst by calcination removes the carbonaceous material but appears not to change the distribution of the metal contaminants. Retesting of the regenerated catalyst shows a performance similar to that of the fresh catalyst. These data serve to support the view that catalyst deactivation during early use is not due to the skin of Ca and Mg on the pellets but rather via the poisoning of active sites by carbonaceous species.

Preliminary studies on the recovery of bitumen from Nigerian tar sands: I. Beneficiation and solvent extraction  

SciTech Connect (OSTI)

Solvent extraction of bitumen from Nigerian tar sands using toluene has been investigated. Pulverization of the tar sands followed by agglomeration in a mechanical shaker resulted in spherical agglomerates having higher bitumen contents than the mined tar sand. The extent of beneficiation was 4% and 19% for the high grade and low grade sands, respectively. Temperature, agitation, and tar sand/solvent (S/L) ratios were found to be significant variables affecting the dissolution of bitumen from the sand. S/L ratio has the greatest effect on extraction efficiency. The rate of bitumen extraction, expressed as extractability eta* showed great dependence on agitation. About 16- and 15-fold increases in extractability were obtained for S/L ratios of 1/20 and 1/5 respectively for a 2.8 fold increase in agitation. At the initial stages of extraction, asphaltene content of the bitumen extracted at 50/sup 0/C was less than that in the bitumen extracted at 25/sup 0/C. This finding could have significant implications for the overall economics of upgrading processes. A high extraction efficiency of about 99% was obtained with stagewise extraction at high tar sand/solvent ratios.

Ultrasonic reactor for the recovery of bitumen from tar sand: Final report  

SciTech Connect (OSTI)

A bench scale ultrasonic reactor was designed for testing to determine its feasiblity for enhancing the dissolution and extraction of bitumen from Utah tar sands using both solvent and water as a liquid medium for dissolution and extraction and to compare the results. The ultrasonic reactor did not significantly enhance dissolution of bitumen into the sovlent. Ultrasonic energy did appear to enhance intraparticle diffusion in consolidated tar sand. The rate of disengagement of the bitumen from the sand in hot water extraction was slightly enhanced and a continuous flow unit may show promise for the recovery of bitumen from tar sands. Assuming that high recovery efficiency can be obtained, the energy requirements for the ultrasonic reactor did not appear to be prohibitive. 5 figs., 3 tabs.

A correlation of United States tar sand bitumen viscosities with NMR spectroscopic parameters  

SciTech Connect (OSTI)

A method has been developed whereby the viscosity of a tar sand bitumen at any temperature can be calculated from nuclear magnetic resonance parameters. The method is semiempirical but is based upon some fundamental theoretical concepts for molecular mobility and intermolecular interactions. Using this method, the viscosities of three United States tar sand bitumens have been correlated to the weighted average spin-spin relaxation rates for the semiliquid, solidlike mobile, and solidlike rigid phases of the bitumens. The results indicate that bitumens with a high viscosity have a greater amount of solidlike rigid phase and lesser amounts of solidlike mobile and semiliquid phases than do the bitumens with low viscosity. It is also shown that the viscosity of a tar sand bitumen over a 100 degree temperature range can be determined from a single NMR experiment conducted near room temperature. 18 refs., 3 figs., 4 tabs.

Solubility of carbon dioxide in tar sand bitumen; Experimental determination and modeling  

SciTech Connect (OSTI)

This paper reports on an understanding of the solubility of carbon dioxide (CO{sub 2}) in tar sand bitumen that is essential for the development of in situ processes in the recovery of bitumen from tar and deposits. The solubility of CO{sub 2} in the Tar Sand Triangle (Utah), the PR Spring Rainbow I (Utah), and the Athabasca (Canada) tar sand bitumens was determined with the use of a high-pressure microbalance at temperatures of 358.2 and 393.2 K and pressures up to 6.2 MPa. As expected, the solubilities increased with pressure at a given temperature and decreased with increases in temperature. The Peng--Robinson and the Schmidt--Wenzel equations of state were used to match the experimentally observed solubilities. Correlations for the interaction parameters between CO{sub 2} and the bitumen were developed for both equations of state, wherein the interaction parameter could be obtained by using specific gravity and the UOP {ital K} factor for the bitumen. The correlations were developed with the optimum interaction parameters obtained for each of the samples at each temperature.

Recovery of heavy crude oil or tar sand oil or bitumen from underground formations  

SciTech Connect (OSTI)

This patent describes a method of producing heavy crude oil or tar sand oil or bitumen from an underground formation. The method consists of utilizing or establishing an aqueous fluid communication path within and through the formation between an injection well or conduit and a production well or conduit by introducing into the formation from the injection well or conduit hot water and/or low quality steam at a temperature in the range about 60{sup 0}-130{sup 0}C and at a substantially neutral or alkaline pH to establish or enlarge the aqueous fluid communication path within the formation from the injection well or conduit to the production well or conduit by movement of the introduced hot water or low quality steam through the formation, increasing the temperature of the injected hot water of low quality steam to a temperature in the range about 110{sup 0}-180{sup 0}C while increasing the pH of the injected hot water or low quality steam to a pH of about 10-13 so as to bring about the movement or migration or stripping of the heavy crude oil or tar sand oil or bitumen from the formation substantially into the hot aqueous fluid communication path with the formation and recovering the resulting produced heavy crude oil or tar sand oil or bitumen from the formation as an emulsion containing less than about 30% oil or bitumen from the production well or conduit.

Characterization of various bitumen samples from tar sands  

SciTech Connect (OSTI)

The authors have investigated twenty three bitumen samples obtained using different separation methods such as: ultracentrifugation, Dean-Stark extraction, solvent extraction employing vigorous agitation, hot water separation and the Solvent Extraction Spherical Agglomeration technique. These samples were extracted from oil sand feedstocks of different grades, Suncor sludge pond tailings and mineral agglomerates obtained form the Solvent Extraction Spherical Agglomeration process. All of the bitumen samples were examined on a comparative basis using various analytical techniques. These included: fractionation into asphaltenes and maltenes: elemental analyses; molecular weight determination using vapour pressure osmometry and gel permeation chromatography, infrared, proton and /sup 13/C nuclear magnetic resonance spectroscopy. Proton /sup 13/C n.m.r. spectroscopic data were used to determine the distribution of various types of hydrogens and carbons in the samples. These data were also used to derive various molecular parameters in order to investigate average molecular structures of different bitumen samples and some of their asphaltene fractions.

Characterization of various bitumen samples from tar sands  

SciTech Connect (OSTI)

Bitumen is a complex mixture of a large of number of organic molecules. The composition of bitumen and the nature of their various individual components has been the subject of considerable research during the past two decades. Various modes of extraction of bitumen from oil sands such as heat, extreme mechanical force, chemical agents and solvents could significantly affect some properties of bitumen. Variations in the composition of the oil sands feed stock could also affect the properties of the extracted bitumen. However, the most commonly used analytical techniques such as elemental analyses, density and viscosity cannot detect small compositional differences in the various samples of bitumen. With developments in instrumentation and techniques the structural characterization of complex petroleum fractions employing high resolution proton and 13/sub C/ nuclear magnetic resonance (NMR) spectroscopy is becoming more popular. The parameters describe structural features, such as the fraction of carbon that is aromatic, the number and length of alkyl substituents in an average molecule, the percentage of aromatic carbons that are substituted and the number of aromatic rings per molecule. Given sufficient data these parameters can provide useful characterization of a hydrocarbon mixture. In the authors' laboratories, the authors have collected a number of bitumen samples obtained from different feedstocks employing a variety of extraction techniques. It was of interest to investigate any differences between these samples from different sources. This paper reports a detailed investigation of average structural parameters by the combined use of elemental analyses, molecular weight determinations and proton and 13/sub C/NMR spectroscopy. A total of twenty three butimen samples have been studied.

Class I cultural resource overview for oil shale and tar sands areas in Colorado, Utah and Wyoming.  

SciTech Connect (OSTI)

In August 2005, the U.S. Congress enacted the Energy Policy Act of 2005, Public Law 109-58. In Section 369 of this Act, also known as the 'Oil Shale, Tar Sands, and Other Strategic Unconventional Fuels Act of 2005', Congress declared that oil shale and tar sands (and other unconventional fuels) are strategically important domestic energy resources that should be developed to reduce the nation's growing dependence on oil from politically and economically unstable foreign sources. The Bureau of Land Management (BLM) is developing a Programmatic Environmental Impact Statement (PEIS) to evaluate alternatives for establishing commercial oil shale and tar sands leasing programs in Colorado, Wyoming, and Utah. This PEIS evaluates the potential impacts of alternatives identifying BLM-administered lands as available for application for commercial leasing of oil shale resources within the three states and of tar sands resources within Utah. The scope of the analysis of the PEIS also includes an assessment of the potential effects of future commercial leasing. This Class I cultural resources study is in support of the Draft Oil Shale and Tar Sands Resource Management Plan Amendments to Address Land Use Allocations in Colorado, Utah, and Wyoming and Programmatic Environmental Impact Statement and is an attempt to synthesize archaeological data covering the most geologically prospective lands for oil shale and tar sands in Colorado, Utah, and Wyoming. This report is based solely on geographic information system (GIS) data held by the Colorado, Utah, and Wyoming State Historic Preservation Offices (SHPOs). The GIS data include the information that the BLM has provided to the SHPOs. The primary purpose of the Class I cultural resources overview is to provide information on the affected environment for the PEIS. Furthermore, this report provides recommendations to support planning decisions and the management of cultural resources that could be impacted by future oil shale and tar sands resource development.

Environmental, health, safety, and socioeconomic concerns associated with oil recovery from US tar-sand deposits: state-of-knowledge  

SciTech Connect (OSTI)

Tar-sand petroleum-extraction procedures undergoing field testing for possible commercial application in the US include both surface (above-ground) and in situ (underground) procedures. The surface tar-sand systems currently being field tested in the US are thermal decomposition processes (retorting), and suspension methods (solvent extraction). Underground bitumen extraction procedures that are also being field tested domestically are in situ combustion and steam-injection. Environmental, health, safety, and socioeconomic concerns associated with construction and operation of 20,000-bbl/d commercial tar-sand surface and in situ facilities have been estimated and are summarized in this report. The principal regulations that commercial tar-sand facilities will need to address are also discussed, and environmental control technologies are summarized and wherever possible, projected costs of emission controls are stated. Finally, the likelihood-of-occurrence of potential environmental, health, and safety problems that have been determined are reviewed, and from this information inference is made as to the environmental acceptability of technologically feasible 20,000-bbl/d commercial tar-sand oil-extraction procedures.

High speed diesel performance/combustion characteristics correlated with structural composition of tar sands derived experimental fuels  

SciTech Connect (OSTI)

Two Canadian tar sands derived experimental diesel fuels with cetane numbers of 26 and 36 and a reference fuel with a cetane number of 47 were tested in a Deutz (FIL511D), single cylinder, 4 stroke, naturally aspirated research engine. The fuels were tested at intake and cooling air temperatures of 30 and 0/sup 0/C. The 36 cetane number fuel was tested with advanced, rated and retarded injection timings. Poor engine speed stability at light loads and excessive rates of combustion pressure rise were experienced with the lowest cetane number fuel. Detailed performance/combustion behavior is presented and a correlation with fuel structural compostiton is made. The analytical techniques used to characterize the fuels included liquid chromatography, gas chromatography mass spectrometry (GC-MS) and proton nuclear magnetic resonance spectrometry (PNMR).

Comparisons of hydrocarbon and nitrogen distributions in geologically diverse tar sand bitumen  

SciTech Connect (OSTI)

The characteristics of bitumens from different tar sand deposits are generally significantly different and affect the utilization of the resource. The chemical and physical properties of bitumen are a result of maturation reactions on the varied organic sediments. For example, saturated hydrocarbon distributions have been related to the geochemical history of organic matter. Very paraffinic or sometimes paraffinic-naphthenic distributions in organic matter are derived from a nonmarine depositional environment. More aromatic and paraffinic-naphthenic hydrocarbon distributions are derived from organic matter deposited in a marine environment. The characteristics of the bitumen also influence the potential for recovery and subsequent processing of the material. For example, saturated hydrocarbons contribute to the high pour points of recovered oils. The origin and composition of an oil influence its viscosity, API gravity, and coke formation during processing, particularly under low-temperature oxidation conditions. The objective of this work is to determine the chemical and physical properties of several samples of bitumen from geologically diverse tar sand deposits. The compound-type distributions and LTD properties of these bitumens are discussed relative to the depositional environment and processing potential of the organic matter.

DOE Patents [OSTI]

A method for treating a tar sands formation includes providing heat to at least part of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. The heat is allowed to transfer from the heaters to at least a portion of the formation. A viscosity of one or more zones of the hydrocarbon layer is assessed. The heating rates in the zones are varied based on the assessed viscosities. The heating rate in a first zone of the formation is greater than the heating rate in a second zone of the formation if the viscosity in the first zone is greater than the viscosity in the second zone. Fluids are produced from the formation through the production wells.

Analysis of techniques for predicting viscosity of heavy oil and tar sand bitumen  

SciTech Connect (OSTI)

Thermal recovery methods are generally employed for recovering heavy oil and tar sand bitumen. These methods rely on reduction of oil viscosity by application of heat as one of the primary mechanisms of oil recovery. Therefore, design and performance prediction of the thermal recovery methods require adequate prediction of oil viscosity as a function of temperature. In this paper, several commonly used temperature-viscosity correlations are analyzed to evaluate their ability to correctly predict heavy oil and bitumen viscosity as a function of temperature. The analysis showed that Ali and Standing`s correlations gave satisfactory results in most cases when properly applied. Guidelines are provided for their application. None of the correlations, however, performed satisfactorily with very heavy oils at low temperatures.

Technology assessment: environmental, health, and safety impacts associated with oil recovery from US tar-sand deposits  

SciTech Connect (OSTI)

The tar-sand resources of the US have the potential to yield as much as 36 billion barrels (bbls) of oil. The tar-sand petroleum-extraction technologies now being considered for commercialization in the United States include both surface (above ground) systems and in situ (underground) procedures. The surface systems currently receiving the most attention include: (1) thermal decomposition processes (retorting); (2) suspension methods (solvent extraction); and (3) washing techniques (water separation). Underground bitumen extraction techniques now being field tested are: (1) in situ combustion; and (2) in situ steam-injection procedures. At this time, any commercial tar-sand facility in the US will have to comply with at least 7 major federal regulations in addition to state regulations; building, electrical, and fire codes; and petroleum-industry construction standards. Pollution-control methods needed by tar-sand technologies to comply with regulatory standards and to protect air, land, and water quality will probably be similar to those already proposed for commercial oil-shale systems. The costs of these systems could range from about $1.20 to $2.45 per barrel of oil produced. Estimates of potential pollution-emisson levels affecting land, air, and water were calculated from available data related to current surface and in situ tar-sand field experiments in the US. These data were then extrapolated to determine pollutant levels expected from conceptual commercial surface and in situ facilities producing 20,000 bbl/d. The likelihood-of-occurrence of these impacts was then assessed. Experience from other industries, including information concerning health and ecosystem damage from air pollutants, measurements of ground-water transport of organic pollutants, and the effectiveness of environmental-control technologies was used to make this assessment.

Size exclusion chromatography-inductively coupled plasma atomic emission spectrographic study of Fe in bitumens derived from tar sands  

SciTech Connect (OSTI)

This paper reports on bitumens extracted from tar sands from various locations (Utah, California, Kentucky, and Alberta) that were examined by size exclusion chromatography with on-line element-specific detection to study the Fe concentration as a function of size. In most cases, the resulting profiles exhibit unimodal distributions at relatively large molecular size with very similar times for maximum elution. specifically, Sunnyside (Utah) and McKittrick (California) tar-sand bitumens exhibited very intense maxima consistent with extremely high bulk Fe contents. Arroyo Grande (California) exhibited an additional maximum at very large molecular size. This size behavior of the Fe appears to correlate with the large molecular size Ni and V components eluted under the same conditions.

Characterization and utilization of hydrotreated products produced from the Whiterocks (Utah) tar sand bitumen-derived liquid  

SciTech Connect (OSTI)

The bitumen-derived liquid produced in a 4-inch diameter fluidized-bed reactor from the mined and crushed ore from the Whiterocks tar sand deposit has been hydrotreated in a fixed-bed reactor. The purpose was to determine the extent of upgrading as a function of process operating variable. A sulfided nickel-molybendum on alumina hydrodenitrogenation catalyst was used in all experiments. Moderately severe operating conditions were employed; that is, high reaction temperature (617--680 K) high reactor pressure (11.0--17.1 MPa) and low liquid feed rate (0.18--0.77 HSV); to achieve the desired reduction in heteroatom content. Detailed chemical structures of the bitumen-derived liquid feedstock and the hydrotreated total liquid products were determined by high resolution gas chromatography - mass spectrometry analyses. The compounds identified in the native bitumen included isoprenoids; bicyclic, tricycle, and tetracyclic terpenoids; steranes; hopanes; and perhydro-{beta}-carotenes. In addition, normal and branched alkanes and alkenes and partially dehydrogenated hydroaromatics were identified in the bitumen-derived liquid. The dominant pyrolysis reactions were: (1) the dealkylation of long alkyl side chains to form {alpha} - and isoolefins; and (2) the cleavage of alkyl chains linking aromatic and hydroaromatic clusters. Olefinic bonds were not observed in the hydrotreated product and monoaromatic hydrocarbons were the predominant aromatic species. The properties of the jet fuel fractions from the hydrotreated products met most of the jet fuel specifications. The cetane indices indicated these fractions would be suitable for use as diesel fuels.

An NMR (nuclear magnetic resonance) investigation of the chemical association and molecular dynamics in asphalt ridge tar sand ore and bitumen  

SciTech Connect (OSTI)

Preliminary studies on tar sand bitumen given in this report have shown that the reassociation of tar sand bitumen to its original molecular configuration after thermal stressing is a first-order process requiring nearly a week to establish equilibrium. Studies were also conducted on the dissolution of tar sand bitumen in solvents of varying polarity. At a high-weight fraction of solute to solvent the apparent molecular weight of the bitumen molecules was greater than that of the original bitumen when dissolved in chloroform-d/sub 1/ and benzene-d/sub 6/. This increase in the apparent molecular weight may be due to micellar formation or a weak solute-solvent molecular complex. Upon further dilution with any of the solvents studied, the apparent molecular weight of the tar sand bitumen decreased because of reduced van der Waals forces of interaction and/or hydrogen bonding. To define the exact nature of the interactions, it will be necessary to have viscosity measurements of the solutions. 30 refs., 3 figs., 3 tabs.

Characterization of Nickel and Vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection  

SciTech Connect (OSTI)

Tar sands represent a tremendous untapped resource for transportation fuels. In the United States alone, over 60 billion barrels of bitumen are estimated to be in place. In order to use this bitumen, it must be somehow separated from the sand. The resulting bitumen is of low quality, and generally will require at least some refining. Typical refinery upgrading methods include fluid catalytic cracking, thermal visbreaking, and residuum hydroconversion. Most of these methods utilize metals-sensitive catalyst. The metals bound in the bitumen are deleterious to catalytic processing, causing rapid deactivation through poisoning and pore mouth plugging. Like heavy crude oil residua, tar sand bitumens have high concentrations of Ni and V. The types of complexes of Ni and V have been studied for heavy crude oils, and can be placed in two broad categories: the metallopetroporphyrins and the metallononporphyrins. The metallopetroporphyrins have been studied extensively. For understanding the behavior of the metals in processing, size exclusion chromatography coupled with element specific detection by inductively coupled plasma atomic emission spectroscopy (SEC-HPLC-ICP) has been applied to several heavy crude oils, residua, and processed products along with separated fractions of feeds and products. These results have shown general important size-behavior features of the metallopetroporphyrins and metallo-nonporphyrins associated with individual feed characteristics. Because of the importance of the metals in a downstream process methods, the authors have applied several of the metallopetroporphyrin and metallo-nonporphyrin examination technique to extracted bitumen from selected tar sands.

Use of a submersible viscometer in the primary separation step of the hot water process for recovery of bitumen from tar sand  

SciTech Connect (OSTI)

The patent describes the primary separation step of the hot water process for extracting bitumen from tar sand in primary separation vessel. The bitumen floats upwardly in a tar sand slurry to form a froth layer, the coarse solids drop to form a tailings layer, and a middlings layer is formed between the froth and the tailings. The improvement described here comprises: providing a submerged viscometer in the middlings layer and actuating the viscometer to measure the viscosity of the middlings at one or more levels in the vertical column of middlings and produce signals, external of the vessel, which are indicative of the measurements; taking sufficient measurements to determine the viscosity of the region of maximum viscosity within the middlings layer and adjusting the viscosity of the middlings in response to the signals to maintain the maximum viscosity in the column below a predetermined value, whereby the flotation of the bitumen through the middlings layer to the froth layer is substantially enhanced.

Pilot plant studies for a new hot water process for extraction of bitumen from Utah tar sands  

SciTech Connect (OSTI)

A process development pilot plant for extracting bitumen from tar sands under arid conditions are described. The hot water recovery process under development is required to maximize heat and water recovery, recover more than 90% of the bitumen, minimize the operating cost, and eliminate the use of a tailings pond by increasing the effectiveness of solids separation and dewatering. Technical aspects of process flow conditions, the liquid cyclone separator under development, and testing to analyze the influence of flow rates, size distribution in discharge streams, amount of bitumen recovery from different streams, and air addition are summarized. Test results indicate that bitumen recovery should be at least 90%, water content from thickener underflow and dewater coarse solids averages about 30 weight percent moisture, and the forced vortex cyclone can produce an underflow solids concentration of 69 to 72 weight percent moisture. The proposed flow sheet is believed to be a very low-cost method for bitumen recovery. 5 refs., 3 figs., 2 tabs.

Tar-free fuel gas production from high temperature pyrolysis of sewage sludge  

SciTech Connect (OSTI)

Highlights: • High temperature pyrolysis of sewage sludge was efficient for producing tar-free fuel gas. • Complete tar removal and volatile matter release were at elevated temperature of 1300 °C. • Sewage sludge was converted to residual solid with high ash content. • 72.60% of energy conversion efficiency for gas production in high temperature pyrolysis. • Investment and costing for tar cleaning were reduced. - Abstract: Pyrolysis of sewage sludge was studied in a free-fall reactor at 1000–1400 °C. The results showed that the volatile matter in the sludge could be completely released to gaseous product at 1300 °C. The high temperature was in favor of H{sub 2} and CO in the produced gas. However, the low heating value (LHV) of the gas decreased from 15.68 MJ/N m{sup 3} to 9.10 MJ/N m{sup 3} with temperature increasing from 1000 °C to 1400 °C. The obtained residual solid was characterized by high ash content. The energy balance indicated that the most heating value in the sludge was in the gaseous product.

Tight gas sands study breaks down drilling and completion costs  

SciTech Connect (OSTI)

Given the high cost to drill and complete tight gas sand wells, advances in drilling and completion technology that result in even modest cost savings to the producer have the potential to generate tremendous savings for the natural gas industry. The Gas Research Institute sponsored a study to evaluate drilling and completion costs in selected tight gas sands. The objective of the study was to identify major expenditures associated with tight gas sand development and determine their relative significance. A substantial sample of well cost data was collected for the study. Individual well cost data were collected from nearly 300 wells in three major tight gas sand formations: the Cotton Valley sand in East Texas, the Frontier sand in Wyoming, and the Wilcox sand in South Texas. The data were collected and organized by cost category for each formation. After the information was input into a data base, a simple statistical analysis was performed. The statistical analysis identified data discrepancies that were then resolved, and it helped allow conclusions to be drawn regarding drilling and completion costs in these tight sand formations. Results are presented.

Characterization of nickel and vanadium compounds in tar sand bitumen by UV-VIS spectroscopy and size exclusion chromatography coupled with element specific detection  

SciTech Connect (OSTI)

Previously, the authors examined the Ni and V in heavy crude oils, residua, and processed products by several metal speciation techniques to ascertain molecular structure and processing behavior. Two classes of metal compounds were found - metallopetroporphyrins and metallo-nonprophyrins - each having unique reactivity during processing. In efforts to better understand the binding of metals in the oil medium, they now examine NI and V in tar sand bitumens. The bitumen was solvent extracted from the sand matrix and was separated by column chromatography and the petroporphyrin content was quantitated by UV-vis spectroscopy. The petroporphyrin contents ranged from virtually none to over 36% of the total metals. Asphalt Ridge (Utah) has primarily Ni petroporphyrins; Big Clifty (Kentucky) and Athabasca (Canada) have primarily V petroporphyrins; Arroyo Grande and McKittrick (California) have roughly equal amounts of both types; and Sunnyside (Utah) has virtually none of either.

Tight sands gain as U.S. gas source  

SciTech Connect (OSTI)

This report, the last of a four part series assessing unconventional gas development in the US, examines the state of the tight gas sands industry following the 1992 expiration of the qualification period for the Sec. 29 Nonconventional Fuels Tax Credit. Because tight gas sands were the most mature of the unconventional gas sources and received only a modest tax credit, one would not expect much change when the tax credit qualification period ended, and post-1992 drilling and production data confirm this. What the overall statistics do not show, and thus the main substance of this article, is how rediscovered tight gas plays and the evolution in tight gas exploration and extraction technology have shifted the outlook for tight gas drilling and its economics from a low productivity, marginally economic resource to a low cost source of gas supply.

The purpose of this research and development project is to provide sample quantities of aviation turbine fuel derived from tar sands and heavy oil feedstocks for testing and evaluation in programs sponsored by the Air Force Wright Aeronautical Laboratories (AFWAL). Samples of specification JP-4 Mil-T-5624L, JP-8 Mil-T-83133A, and variable quality JP-4 samples were produced via pilot plant operations. Data generated from Phases I, II, and III, were used to 1) optimize the processing scheme, 2) generate process material and energy balances for a commercial-sized plant, and 3) provide a detailed final flow diagram of the processing scheme. A final economic analysis was performed based on all contract data available.

Turbine fuels from tar-sands bitumen and heavy oil. Part 2. Phase II. Laboratory sample production. Interim report, 1 October 1983-31 October 1985  

SciTech Connect (OSTI)

The conversion of domestic tar-sands bitumens or heavy crude oils into aviation turbine fuels was studied in small scale equipment to demonstrate the process scheme consisting of hydrovisbreaking the bitumen or crude residuum follwed by catalytic hydrotreating or hydrocracking of the resultant naphtha or distillate fractions. Four different feedstocks were employed; two were bitumens (from Kentucky or Utah) and two were heavy crudes from California. Significant operating parameters were examined for each process step. Prototype naphtha and kerosene-type fuel samples compared well with JP-4 and JP-8 specifications, although fuels prepared from Utah bitumen (Sunnyside deposit) were deficient in freeze point. Initiation of Phase III, pilot-plant-scale evaluation of the process is recommended.

Characterization of nickel and vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection  

SciTech Connect (OSTI)

Previously, we have examined the Ni and V in heavy crude oils, residua, and processed products by several metal speciation techniques to ascertain molecular structure and processing behavior. Two classes of metal compounds were found/--/metallopetroporphyrins and metallo-nonporphyrins/--/each having unique reactivity during processing. In efforts to better understand the binding of metals in the oil medium, we have now examined Ni and V in tar sand bitumens. The bitumen was solvent extracted from the sand matrix and was separated by column chromatography to quantitate petroporphyrin content. The petroporphyrin contents ranged from virtually none to over 36% of the total metals. Asphalt Ridge (Utah) has primarily Ni petroporphyrins; Big Clifty (Kentucky) and Athabasca (Canada) have primarily V petroporphyrins; Arroyo Grande and McKittrick (California) have roughly equal amounts of both types; and Sunnyside (Utah) has virtually none of either. Size characteristic profiles (SEC-HPLC-ICP) were generated for the extracted bitumens. The profiles are generally bimodal in shape and resemble several different specific heavy crude oils and residua. For examples, Arroyo Grande and McKittrick appear to be similar to Kern River (California) 650/degree/F+ residuum, while Athabasca resembles Morichal (Venezuela) 650/degree/F+ residuum. These results will be discussed in terms of generalized profile and petroporphyrin behavior. 23 refs., 3 figs., 3 tabs.

Research investigations in oil shale, tar sand, coal research, advanced exploratory process technology, and advanced fuels research: Volume 1 -- Base program. Final report, October 1986--September 1993  

SciTech Connect (OSTI)

Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investigations were conducted under the Base Program to determine the physical and chemical properties of materials suitable for conversion to liquid and gaseous fuels, to test and evaluate processes and innovative concepts for such conversions, to monitor and determine environmental impacts related to development of commercial-sized operations, and to evaluate methods for mitigation of potential environmental impacts. This report is divided into two volumes: Volume 1 consists of 28 summaries that describe the principal research efforts conducted under the Base Program in five topic areas. Volume 2 describes tasks performed within the JSRP. Research conducted under this agreement has resulted in technology transfer of a variety of energy-related research information. A listing of related publications and presentations is given at the end of each research topic summary. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

Tight Oklahoma gas sands remain an attractive play  

SciTech Connect (OSTI)

The Cherokee tight gas sands of Oklahoma remain an attractive play because of improvements in drilling and completion practices and actions by the Oklahoma Corporation Commission (OCC) that allow separate allowables for new wells. The expired federal tax credits for tight gas wells have not been the only reason for increased activity. Since decontrol of most regulated gas pricing and since 1986, the number of wells drilled and gas production per well have been increasing in the cherokee area while overall drilling in Oklahoma has decreased. These conclusions are based on wells as categorized by permit date and not by the spud, completion, or first production date. A few wells outside but adjacent to the Cherokee area may have been included, although, their impact on the conclusions is considered nominal. The paper discusses the tight gas credit, proration units, the concept of separate allowables, costs, completion efficiency, and the economic outlook for this area.

Western Gas Sands Project. Status report, April-June 1982  

SciTech Connect (OSTI)

The progress during April, May and June 1982, of government-sponsored projects to increase gas production from low permeability gas sands of the Western United States, is summarized in this edition of the WGSP Quarterly Status Report. In an effort to eliminate wellbore storage during the testing of tight reservoirs and substantially reduce time and cost of testing, CER Corporation is investigating downhole shut-off to develop a shut-off tool. During the quarter, the University of Oklahoma completed the two-dimensional lenticular well simulator model and submitted a final report. At Lawrence Livermore National Laboratories, work is complete on the 2-D crack model and work has begun on developing a pseudo 3-D crack model. Preparations have begun at Los Alamos National Laboratory to test the 6-in. permanent magnet pre-prototype tool in the American Petroleum Institute test pit at the University of Houston. At Sandia National Laboratories, an analytical version of the Surface Electrical Potential (SEP) mathematical model has been completed. The data provided by DOE Well Test Facility's drill stem test (DST) of MWX-1 indicated wellbore storage was predominant during the buildup period of the test and essentially masks the pressure transient normally used in the DST analysis. For the Multi-Well Experiment program, cased hole logging, directional surveys and two geophysical surveys were accomplished this quarter. 38 figures.

Occurrence of gas hydrate in Oligocene Frio sand: Alaminos Canyon Block 818: Northern Gulf of Mexico  

SciTech Connect (OSTI)

A unique set of high-quality downhole shallow subsurface well log data combined with industry standard 3D seismic data from the Alaminos Canyon area has enabled the first detailed description of a concentrated gas hydrate accumulation within sand in the Gulf of Mexico. The gas hydrate occurs within very fine grained, immature volcaniclastic sands of the Oligocene Frio sand. Analysis of well data acquired from the Alaminos Canyon Block 818 No.1 ('Tigershark') well shows a total gas hydrate occurrence 13 m thick, with inferred gas hydrate saturation as high as 80% of sediment pore space. Average porosity in the reservoir is estimated from log data at approximately 42%. Permeability in the absence of gas hydrates, as revealed from the analysis of core samples retrieved from the well, ranges from 600 to 1500 millidarcies. The 3-D seismic data reveals a strong reflector consistent with significant increase in acoustic velocities that correlates with the top of the gas-hydrate-bearing sand. This reflector extends across an area of approximately 0.8 km{sup 2} and delineates the minimal probable extent of the gas hydrate accumulation. The base of the inferred gas-hydrate zone also correlates well with a very strong seismic reflector that indicates transition into units of significantly reduced acoustic velocity. Seismic inversion analyses indicate uniformly high gas-hydrate saturations throughout the region where the Frio sand exists within the gas hydrate stability zone. Numerical modeling of the potential production of natural gas from the interpreted accumulation indicates serious challenges for depressurization-based production in settings with strong potential pressure support from extensive underlying aquifers.

This paper summarizes an evaluation of siting an HTGR plant in a remote area supplying steam, electricity and high temperature gas for recovery and upgrading of unconventional crude oil from oil sands. The area selected for this evaluation is the Alberta Canada oil sands. This is a very fertile and active area for bitumen recovery and upgrading with significant quantities piped to refineries in Canada and the U.S Additionally data on the energy consumption and other factors that are required to complete the evaluation of HTGR application is readily available in the public domain. There is also interest by the Alberta oil sands producers (OSP) in identifying alternative energy sources for their operations. It should be noted, however, that the results of this evaluation could be applied to any similar oil sands area.

Production of Natural Gas and Fluid Flow in Tight Sand Reservoirs  

SciTech Connect (OSTI)

This document reports progress of this research effort in identifying possible relationships and defining dependencies between macroscopic reservoir parameters strongly affected by microscopic flow dynamics and production well performance in tight gas sand reservoirs. Based on a critical review of the available literature, a better understanding of the main weaknesses of the current state of the art of modeling and simulation for tight sand reservoirs has been reached. Progress has been made in the development and implementation of a simple reservoir simulator that is still able to overcome some of the deficiencies detected. The simulator will be used to quantify the impact of microscopic phenomena in the macroscopic behavior of tight sand gas reservoirs. Phenomena such as, Knudsen diffusion, electro-kinetic effects, ordinary diffusion mechanisms and water vaporization are being considered as part of this study. To date, the adequate modeling of gas slippage in porous media has been determined to be of great relevance in order to explain unexpected fluid flow behavior in tight sand reservoirs.

Production of Natural Gas and Fluid Flow in Tight Sand Reservoirs  

SciTech Connect (OSTI)

This document reports progress of this research effort in identifying relationships and defining dependencies between macroscopic reservoir parameters strongly affected by microscopic flow dynamics and production well performance in tight gas sand reservoirs. These dependencies are investigated by identifying the main transport mechanisms at the pore scale that should affect fluids flow at the reservoir scale. A critical review of commercial reservoir simulators, used to predict tight sand gas reservoir, revealed that many are poor when used to model fluid flow through tight reservoirs. Conventional simulators ignore altogether or model incorrectly certain phenomena such as, Knudsen diffusion, electro-kinetic effects, ordinary diffusion mechanisms and water vaporization. We studied the effect of Knudsen's number in Klinkenberg's equation and evaluated the effect of different flow regimes on Klinkenberg's parameter b. We developed a model capable of explaining the pressure dependence of this parameter that has been experimentally observed, but not explained in the conventional formalisms. We demonstrated the relevance of this, so far ignored effect, in tight sands reservoir modeling. A 2-D numerical simulator based on equations that capture the above mentioned phenomena was developed. Dynamic implications of new equations are comprehensively discussed in our work and their relative contribution to the flow rate is evaluated. We performed several simulation sensitivity studies that evidenced that, in general terms, our formalism should be implemented in order to get more reliable tight sands gas reservoirs' predictions.

Investigation of coal tar mobility at a former MGP site  

SciTech Connect (OSTI)

The presence of coal tar in the subsurface of former manufactured gas plant sites poses an environmental hazard and a potential threat to public health. Coal tar can release various chemical compounds that are transported into the groundwater. Before any efforts can be made to remove coal tar from contaminated subsurface soils, it is recommended to characterize coal tar properties and composition and to delineate the residual saturation point between mobile and immobile coal tar. This paper presents a new innovative field device, the Res-SAT field tool, and laboratory procedures that can be used to determine the saturation-capillary pressure relationship for a soil-water coal-tar system and the critical pressure for coal tar mobility.

Pore-scale mechanisms of gas flow in tight sand reservoirs  

SciTech Connect (OSTI)

Tight gas sands are unconventional hydrocarbon energy resource storing large volume of natural gas. Microscopy and 3D imaging of reservoir samples at different scales and resolutions provide insights into the coaredo not significantly smaller in size than conventional sandstones, the extremely dense grain packing makes the pore space tortuous, and the porosity is small. In some cases the inter-granular void space is presented by micron-scale slits, whose geometry requires imaging at submicron resolutions. Maximal Inscribed Spheres computations simulate different scenarios of capillary-equilibrium two-phase fluid displacement. For tight sands, the simulations predict an unusually low wetting fluid saturation threshold, at which the non-wetting phase becomes disconnected. Flow simulations in combination with Maximal Inscribed Spheres computations evaluate relative permeability curves. The computations show that at the threshold saturation, when the nonwetting fluid becomes disconnected, the flow of both fluids is practically blocked. The nonwetting phase is immobile due to the disconnectedness, while the permeability to the wetting phase remains essentially equal to zero due to the pore space geometry. This observation explains the Permeability Jail, which was defined earlier by others. The gas is trapped by capillarity, and the brine is immobile due to the dynamic effects. At the same time, in drainage, simulations predict that the mobility of at least one of the fluids is greater than zero at all saturations. A pore-scale model of gas condensate dropout predicts the rate to be proportional to the scalar product of the fluid velocity and pressure gradient. The narrowest constriction in the flow path is subject to the highest rate of condensation. The pore-scale model naturally upscales to the Panfilov's Darcy-scale model, which implies that the condensate dropout rate is proportional to the pressure gradient squared. Pressure gradient is the greatest near the matrix-fracture interface. The distinctive two-phase flow properties of tight sand imply that a small amount of gas condensate can seriously affect the recovery rate by blocking gas flow. Dry gas injection, pressure maintenance, or heating can help to preserve the mobility of gas phase. A small amount of water can increase the mobility of gas condensate.

Design and Implementation of Energized Fracture Treatment in Tight Gas Sands  

SciTech Connect (OSTI)

Hydraulic fracturing is essential for producing gas and oil at an economic rate from low permeability sands. Most fracturing treatments use water and polymers with a gelling agent as a fracturing fluid. The water is held in the small pore spaces by capillary pressure and is not recovered when drawdown pressures are low. The un-recovered water leaves a water saturated zone around the fracture face that stops the flow of gas into the fracture. This is a particularly acute problem in low permeability formations where capillary pressures are high. Depletion (lower reservoir pressures) causes a limitation on the drawdown pressure that can be applied. A hydraulic fracturing process can be energized by the addition of a compressible, sometimes soluble, gas phase into the treatment fluid. When the well is produced, the energized fluid expands and gas comes out of solution. Energizing the fluid creates high gas saturation in the invaded zone, thereby facilitating gas flowback. A new compositional hydraulic fracturing model has been created (EFRAC). This is the first model to include changes in composition, temperature, and phase behavior of the fluid inside the fracture. An equation of state is used to evaluate the phase behavior of the fluid. These compositional effects are coupled with the fluid rheology, proppant transport, and mechanics of fracture growth to create a general model for fracture creation when energized fluids are used. In addition to the fracture propagation model, we have also introduced another new model for hydraulically fractured well productivity. This is the first and only model that takes into account both finite fracture conductivity and damage in the invaded zone in a simple analytical way. EFRAC was successfully used to simulate several fracture treatments in a gas field in South Texas. Based on production estimates, energized fluids may be required when drawdown pressures are smaller than the capillary forces in the formation. For this field, the minimum CO{sub 2} gas quality (volume % of gas) recommended is 30% for moderate differences between fracture and reservoir pressures (2900 psi reservoir, 5300 psi fracture). The minimum quality is reduced to 20% when the difference between pressures is larger, resulting in additional gas expansion in the invaded zone. Inlet fluid temperature, flow rate, and base viscosity did not have a large impact on fracture production. Finally, every stage of the fracturing treatment should be energized with a gas component to ensure high gas saturation in the invaded zone. A second, more general, sensitivity study was conducted. Simulations show that CO{sub 2} outperforms N{sub 2} as a fluid component because it has higher solubility in water at fracturing temperatures and pressures. In fact, all gas components with higher solubility in water will increase the fluid's ability to reduce damage in the invaded zone. Adding methanol to the fracturing solution can increase the solubility of CO{sub 2}. N{sub 2} should only be used if the gas leaks-off either during the creation of the fracture or during closure, resulting in gas going into the invaded zone. Experimental data is needed to determine if the gas phase leaks-off during the creation of the fracture. Simulations show that the bubbles in a fluid traveling across the face of a porous medium are not likely to attach to the surface of the rock, the filter cake, or penetrate far into the porous medium. In summary, this research has created the first compositional fracturing simulator, a useful tool to aid in energized fracture design. We have made several important and original conclusions about the best practices when using energized fluids in tight gas sands. The models and tools presented here may be used in the future to predict behavior of any multi-phase or multi-component fracturing fluid system.

A new one-dimensional coke oven model has been developed for simulating the amount and the characteristics of by-products such as tar and gas as well as coke. This model consists of both heat transfer and chemical kinetics including thermal decomposition of coal and tar. The chemical kinetics constants are obtained by estimation based on the results of experiments conducted to investigate the thermal decomposition of both coal and tar. The calculation results using the new model are in good agreement with experimental ones.

Western gas sands project. Status report, July-August-September 1981  

SciTech Connect (OSTI)

The progress during July, August and September 1981 on increasing gas production from low permeability gas sands of the Western United States, is summarized in this edition of the WGSP Quarterly Status Report. During the quarter, CK GeoEnergy completed the field work in the Rifle Gap area near Rifle, Colorado, as well as the Draft Phase VI report covering the prognosis about reservoir geometry in the Multi-Well site area. The improved pressure coring system project, officially terminated Sept. 30. Accomplishments included increased capabilities for the pressure core barrel, improvements in the low invasion fluid plus various laboratory core intrusion studies and improved designs for PDC drill bits. At Lawrence Livermore National Laboratory, the P/sup 2/L/sup 2/ system described last quarter was evaluated further and the decision has been made to abandon further investigation. The Los Alamos National Laboratory Ceramics Materials Group is preparing to fabricate a ceramic sample with cylindrical pores of specified diameters. The NMR data on this type sample will contribute to a better understanding of the parameters affecting NMR relaxation rates in porous media. During the quarter, modifications were made in the operating and application software of the DOE Well Test Facility, which will support additions to the PDP-11/10 computer system. The Multi-Well Experiment well was spudded on Sept. 13 and by Sept. 30, total depth was 3358 ft. Coring operations are expected to begin at a depth of 4150 ft. At the Nevada Test Site, Sandia National Laboratories completed four additional coreholes for the Fluid Mechanics/ Proppant Transport Experiments.

Task 3.9 -- Catalytic tar cracking. Semi-annual report, January 1--June 30, 1995  

SciTech Connect (OSTI)

Tar produced in the gasification of coal is deleterious to the operation of downstream equipment including fuel cells, gas turbines, hot-gas stream cleanup filters, and pressure swing adsorption systems. Catalytic cracking of tars to smaller hydrocarbons can be an effective means to remove these tars from gas streams and, in the process, generate useful products, e.g., methane gas, which is crucial to the operation of molten carbonate fuel cells. The objectives of this project are to investigate whether gasification tars can be cracked by synthetic nickel-substituted micamontmorillonite, zeolite, or dolomite material; and whether the tars can be cracked selectively by these catalysts to produce a desired liquid and/or gas stream. Results to date are presented in the cited papers.

Hydraulic fracture model and diagnostics verification at GRI/DOE multi-site projects and tight gas sand program support. Final report, July 28, 1993--February 28, 1997  

SciTech Connect (OSTI)

The Mesaverde Group of the Piceance Basin in western Colorado has been a pilot study area for government-sponsored tight gas sand research for over twenty years. Early production experiments included nuclear stimulations and massive hydraulic fracture treatments. This work culminated in the US Department of Energy (DOE)`s Multiwell Experiment (MWX), a field laboratory designed to study the reservoir and production characteristics of low permeability sands. A key feature of MWX was an infrastructure which included several closely spaced wells that allowed detailed characterization of the reservoir through log and core analysis, and well testing. Interference and tracer tests, as well as the use of fracture diagnostics gave further information on stimulation and production characteristics. Thus, the Multiwell Experiment provided a unique opportunity for identifying the factors affecting production from tight gas sand reservoirs. The purpose of this operation was to support the gathering of field data that may be used to resolve the number of unknowns associated with measuring and modeling the dimensions of hydraulic fractures. Using the close-well infrastructure at the Multiwell Site near Rifle, Colorado, this operation focused primarily on the field design and execution of experiments. The data derived from the experiments were gathered and analyzed by DOE team contractors.

Recent developments in drill-stem test interpretation useful to explorationists in tight gas sand plays and in identifying reservoirs with linear geometry  

SciTech Connect (OSTI)

Two major areas of recent development in drill-stem testing are of particular interest to geologists. The first is the use of closed chamber DST's to evaluate the very tight gas sands currently under intense exploration in areas such as Alberta's Deep basin and various intermontane basins in the US Rocky Mountain province. Field examples from the Deep basin of Alberta are shown together with results after completion. Other applications are shown. The second development is the use of DST data to identify reservoirs with linear flow geometry. Geologic situations where flow into the well bore during a test can be considered linear rather than truly radial include long narrow reservoirs with parallel boundaries such as channel sands, zones bounded by parallel sealing-fault boundaries, or naturally fractured reservoirs where an open fracture intersects the well bore.

Integrated Biomass Gasification with Catalytic Partial Oxidation for Selective Tar Conversion  

SciTech Connect (OSTI)

Biomass gasification is a flexible and efficient way of utilizing widely available domestic renewable resources. Syngas from biomass has the potential for biofuels production, which will enhance energy security and environmental benefits. Additionally, with the successful development of low Btu fuel engines (e.g. GE Jenbacher engines), syngas from biomass can be efficiently used for power/heat co-generation. However, biomass gasification has not been widely commercialized because of a number of technical/economic issues related to gasifier design and syngas cleanup. Biomass gasification, due to its scale limitation, cannot afford to use pure oxygen as the gasification agent that used in coal gasification. Because, it uses air instead of oxygen, the biomass gasification temperature is much lower than well-understood coal gasification. The low temperature leads to a lot of tar formation and the tar can gum up the downstream equipment. Thus, the biomass gasification tar removal is a critical technology challenge for all types of biomass gasifiers. This USDA/DOE funded program (award number: DE-FG36-O8GO18085) aims to develop an advanced catalytic tar conversion system that can economically and efficiently convert tar into useful light gases (such as syngas) for downstream fuel synthesis or power generation. This program has been executed by GE Global Research in Irvine, CA, in collaboration with Professor Lanny Schmidt's group at the University of Minnesota (UoMn). Biomass gasification produces a raw syngas stream containing H2, CO, CO2, H2O, CH4 and other hydrocarbons, tars, char, and ash. Tars are defined as organic compounds that are condensable at room temperature and are assumed to be largely aromatic. Downstream units in biomass gasification such as gas engine, turbine or fuel synthesis reactors require stringent control in syngas quality, especially tar content to avoid plugging (gum) of downstream equipment. Tar- and ash-free syngas streams are a critical requirement for commercial deployment of biomass-based power/heat co-generation and biofuels production. There are several commonly used syngas clean-up technologies: (1) Syngas cooling and water scrubbing has been commercially proven but efficiency is low and it is only effective at small scales. This route is accompanied with troublesome wastewater treatment. (2) The tar filtration method requires frequent filter replacement and solid residue treatment, leading to high operation and capital costs. (3) Thermal destruction typically operates at temperatures higher than 1000oC. It has slow kinetics and potential soot formation issues. The system is expensive and materials are not reliable at high temperatures. (4) In-bed cracking catalysts show rapid deactivation, with durability to be demonstrated. (5) External catalytic cracking or steam reforming has low thermal efficiency and is faced with problematic catalyst coking. Under this program, catalytic partial oxidation (CPO) is being evaluated for syngas tar clean-up in biomass gasification. The CPO reaction is exothermic, implying that no external heat is needed and the system is of high thermal efficiency. CPO is capable of processing large gas volume, indicating a very compact catalyst bed and a low reactor cost. Instead of traditional physical removal of tar, the CPO concept converts tar into useful light gases (eg. CO, H2, CH4). This eliminates waste treatment and disposal requirements. All those advantages make the CPO catalytic tar conversion system a viable solution for biomass gasification downstream gas clean-up. This program was conducted from October 1 2008 to February 28 2011 and divided into five major tasks. - Task A: Perform conceptual design and conduct preliminary system and economic analysis (Q1 2009 ~ Q2 2009) - Task B: Biomass gasification tests, product characterization, and CPO tar conversion catalyst preparation. This task will be conducted after completing process design and system economics analysis. Major milestones include identification of syngas cleaning requirements for proposed system

Sedimentology, diagenesis, and trapping style, Chesterian Tar Springs sandstone at Inman Field, Gallatin County, Illinois  

SciTech Connect (OSTI)

The Tar Springs Sandstone in southern Illinois is often over-looked as a pay, yet it can be a prolific producer. The Inman Field, discovered in 1940, produces from several cyclic Chesterian sandstones from structural-stratigraphic traps in the Wabash Valley Fault System of southeastern Illinois. The oil was sourced from the Devonian New Albany Shale and apparently migrated vertically along the Wabash Valley faults to its present location, thus charging many of the Chesterian and lower Pennsylvanian sands in the field. The Tar Springs Sandstone produces from stacked distributary channel sand reservoirs up to 125 feet thick which have cut up to 40 feet into laterally equivalent non-reservoir, delta-fringe facies and the underlying Glen Dean Limestone. The reservoir sands are well-sorted, fine- to medium-grained quartz arenites with less than 5% feldspar and chert. Quartz grains have quartz overgrowths. Feldspar grains are clouded in thin-section and show pronounced etching and dissolution in SEM. Diagenetic kaolinite and small amounts of illite and magnesium-rich chlorite occur in intergranular pores. Sparry, iron-rich dolomite or ankerite that fills pores in irregular millimeter-size patches, occupies up to 10% of the reservoir rock. Typical reservoir porosity ranges from 16 to 19 percent and permeability ranges from 60 to 700 md. By contrast non-reservoir delta-fringe sands typically have porosities of 6 to 12 percent and permeabilities of 1 to 20 md. Delta-fringe Tar Springs shales act as impermeable lateral and vertical seals, aiding in stratigraphic trapping.

PAHs and organic matter partitioning and mass transfer from coal tar particles to water  

SciTech Connect (OSTI)

The coal tar found in contaminated soils of former manufactured gas plants and coking plants acts as a long-term source of PAHs. Organic carbon and PAH transfer from coal tar particles to water was investigated with closed-looped laboratory column experiments run at various particle sizes and temperatures. Two models were derived. The first one represented the extraction process at equilibrium and was based on a linear partitioning of TOC and PAHs between coal tar and water. The partition coefficient was derived as well as the mass of extractable organic matter in the particles. The second model dealt with mass transfer. Particle diffusion was the limiting step; organic matter diffusivity in the coal tar was then computed in the different conditions. A good consistency was obtained between experimental and computed results. Hence, the modeling of PAH migration in contaminated soils at the field scale requires taking into account coal tar as the source-term for PAH release. 28 refs., 5 figs., 3 tabs.

GC/MS characterization of condensable tars in the output stream of a stirred fixed-bed gasifier  

SciTech Connect (OSTI)

The output stream of the stirred fixed-bed gasifier at the Morgantown Energy Technology Center was sampled for total entrained material. A major portion of the entrained material, in addition to particles, is condensable tar that is subsequently removed from the process gas by wet scrubbing. Characterization of the entrained materials, specifically the tar, is important to establish contaminant levels and to evaluate performance of downstream cleanup units. Samples of tars were collected from the process unit in a combined ice, dry ice, and liquid nitrogen sampler and stored in a refrigerator. The tar samples were then separated into asphaltene, neutral oil, tar acid, and base fractions by solvent extraction using toluene, pentane, sulfuric acid, and potassium hydroxide extraction. Characterization of the fractions obtained from these tars include IR, UV, GC, and GC/MS analysis. The mass spectrometer analysis of the various isolates shows that many individual peaks in the gas chromatograph are in fact mixtures that can be readily identified by the mass spectrometer. It was found that many of the species identified in these fractions were members of aromatic homologous series consisting of parent, mono, di, and tri substituted compounds. Compound identification was made by comparison of the data system library and standard reference spectra. This paper will discuss the instrumental approach and limitation of the GC/MS and the results of the characterization studies of entrained hydrocarbons collected from the gasifier stream.

Biomass waste gasification - Can be the two stage process suitable for tar reduction and power generation?  

SciTech Connect (OSTI)

Highlights: Black-Right-Pointing-Pointer Comparison of one stage (co-current) and two stage gasification of wood pellets. Black-Right-Pointing-Pointer Original arrangement with grate-less reactor and upward moving bed of the pellets. Black-Right-Pointing-Pointer Two stage gasification leads to drastic reduction of tar content in gas. Black-Right-Pointing-Pointer One stage gasification produces gas with higher LHV at lower overall ER. Black-Right-Pointing-Pointer Content of ammonia in gas is lower in two stage moving bed gasification. - Abstract: A pilot scale gasification unit with novel co-current, updraft arrangement in the first stage and counter-current downdraft in the second stage was developed and exploited for studying effects of two stage gasification in comparison with one stage gasification of biomass (wood pellets) on fuel gas composition and attainable gas purity. Significant producer gas parameters (gas composition, heating value, content of tar compounds, content of inorganic gas impurities) were compared for the two stage and the one stage method of the gasification arrangement with only the upward moving bed (co-current updraft). The main novel features of the gasifier conception include grate-less reactor, upward moving bed of biomass particles (e.g. pellets) by means of a screw elevator with changeable rotational speed and gradual expanding diameter of the cylindrical reactor in the part above the upper end of the screw. The gasifier concept and arrangement are considered convenient for thermal power range 100-350 kW{sub th}. The second stage of the gasifier served mainly for tar compounds destruction/reforming by increased temperature (around 950 Degree-Sign C) and for gasification reaction of the fuel gas with char. The second stage used additional combustion of the fuel gas by preheated secondary air for attaining higher temperature and faster gasification of the remaining char from the first stage. The measurements of gas composition and tar compound contents confirmed superiority of the two stage gasification system, drastic decrease of aromatic compounds with two and higher number of benzene rings by 1-2 orders. On the other hand the two stage gasification (with overall ER = 0.71) led to substantial reduction of gas heating value (LHV = 3.15 MJ/Nm{sup 3}), elevation of gas volume and increase of nitrogen content in fuel gas. The increased temperature (>950 Degree-Sign C) at the entrance to the char bed caused also substantial decrease of ammonia content in fuel gas. The char with higher content of ash leaving the second stage presented only few mass% of the inlet biomass stream.

A study of the structure of the hydrocarbons of primary hard-coal tar  

SciTech Connect (OSTI)

The hydrocarbons isolated from primary hard-coal (G/sub 6/ gas coal) tar have been investigated by a combination of physicochemical and chemical methods. It has been established that the hydrocarbons boiling up to 573 K are mainly aliphatic, hydroaromatic, and naphthenic and are aromatic only to a smaller degree. Molecular and presumable structural formulas of the oxygen compounds isolated from the 473-573 K hydrocarbon fraction have been derived.

VAPOR PRESSURES AND HEATS OF VAPORIZATION OF PRIMARY COAL TARS  

SciTech Connect (OSTI)

This project had as its main focus the determination of vapor pressures of coal pyrolysis tars. It involved performing measurements of these vapor pressures and from them, developing vapor pressure correlations suitable for use in advanced pyrolysis models (those models which explicitly account for mass transport limitations). This report is divided into five main chapters. Each chapter is a relatively stand-alone section. Chapter A reviews the general nature of coal tars and gives a summary of existing vapor pressure correlations for coal tars and model compounds. Chapter B summarizes the main experimental approaches for coal tar preparation and characterization which have been used throughout the project. Chapter C is concerned with the selection of the model compounds for coal pyrolysis tars and reviews the data available to us on the vapor pressures of high boiling point aromatic compounds. This chapter also deals with the question of identifying factors that govern the vapor pressures of coal tar model materials and their mixtures. Chapter D covers the vapor pressures and heats of vaporization of primary cellulose tars. Chapter E discusses the results of the main focus of this study. In summary, this work provides improved understanding of the volatility of coal and cellulose pyrolysis tars. It has resulted in new experimentally verified vapor pressure correlations for use in pyrolysis models. Further research on this topic should aim at developing general vapor pressure correlations for all coal tars, based on their molecular weight together with certain specific chemical characteristics i.e. hydroxyl group content.

Structural group composition and thermodynamic properties of petroleum and coal tar fractions  

SciTech Connect (OSTI)

The improved G-L method was developed for determining the structural group composition of petroleum and coal tar fractions by using experimental values of refraction index, density, molecular weight, and S, N, O, and olefinic group content. The method is useful for fractions boiling in the range 30--500 C containing S, N, O and in total up to 10%, not limiting the distribution of the carbon atoms between aromatic, naphthenic, and paraffinic structures. Several correlations are proposed for prediction of the thermodynamic properties of petroleum and coal tar fractions, i.e., molar volume; surface tension; heat capacity in gas, liquid, and solid phases as a function of temperature; and also critical properties standard heat and entropy of formation, and temperature and entropy of melting. The method and these correlations have been tested on hydrocarbons and other organic compounds with satisfactory accuracy.

Preparation of environmental analyses for synfuel and unconventional gas technologies  

SciTech Connect (OSTI)

Government agencies that offer financial incentives to stimulate the commercialization of synfuel and unconventional gas technologies usually require an analysis of environmental impacts resulting from proposed projects. This report reviews potentially significant environmental issues associated with a selection of these technologies and presents guidance for developing information and preparing analyses to address these issues. The technologies considered are western oil shale, tar sand, coal liquefaction and gasification, peat, unconventional gas (western tight gas sands, eastern Devonian gas shales, methane from coal seams, and methane from geopressured aquifers), and fuel ethanol. Potentially significant issues are discussed under the general categories of land use, air quality, water use, water quality, biota, solid waste disposal, socioeconomics, and health and safety. The guidance provided in this report can be applied to preparation and/or review of proposals, environmental reports, environmental assessments, environmental impact statements, and other types of environmental analyses. The amount of detail required for any issue discussed must, by necessity, be determined on a case-by-case basis.

Review of Novel Catalysts for Biomass Tar Cracking and Methane Reforming  

SciTech Connect (OSTI)

A review of the literature was conducted to examine the performance of catalysts other than conventional nickel catalysts, and alkaline earth and olivine based catalysts for treating hot raw product gas from a biomass gasifier to convert methane and tars into synthesis gas. Metal catalysts other than Ni included precious metals Rh, Ru, Ir, Pt, and Pd, as well as Cu, Co, and Fe in limited testing. Nickel catalysts promoted with Rh, Zr, Mn, Mo, Ti, Ag, or Sn were also examined, as were Ni catalysts on Ce2O3, TiO2, ZrO2, SiO2, and La2O3. In general, Rh stood out as a consistently superior metal catalyst for methane reforming, tar cracking, and minimizing carbon buildup on the catalyst. Ru and Ir also showed significant improvement over Ni for methane reforming. Ceria stood out as good support material and particularly good promoter material when added in small quantities to another support material such as alumina, zirconia, or olivine. Other promising supports were lanthana, zirconia, and titania.

Alcohol flushing for enhanced removal of coal tar from contaminated soils  

SciTech Connect (OSTI)

Alcohol flushing for enhancing the removal of coal tar from contaminated soils and reducing coal tar concentrations in the aqueous-phase leachate was investigated. Four soil columns were packed with relatively undisturbed coal tar contaminated soils collected from a former coal gasification site. These columns were leached with water and then flushed with isopropyl alcohol (IPA) solutions. Initially, total coal tar concentrations in water leachate ranged from = 0.1 to 150 mg/L for the four columns. Coal tar concentrations in the column effluent generally increased three to five orders of magnitude during the initial IPA flush. Each column was flushed with 1-3 pore volumes of an IPA solution. Reduction of coal tar concentrations in water leachate, attributed to the alcohol flushing, was noted in three of the four columns. The total coal tar removed from the soil columns during the IPA flushes constituted from 54 to 97% of the total coal tar removed during both water leaching (240-800 pore volumes) and alcohol flushing (1-3 pore volumes). The alcohol flushing removed from 3 to 19 % of the total coal tar in the various soil columns. Results indicated that alcohol flushing can enhance the removal of coal tar from contaminated soils and can reduce the aqueous-phase coal tar concentrations in the leachate. 16 refs., 5 figs., 3 tabs.

The extraction of bitumen from western oil sands. Annual report, July 1991--July 1992  

SciTech Connect (OSTI)

The University of Utah tar sand research and development program is concerned with research and development on Utah is extensive oil sands deposits. The program has been intended to develop a scientific and technological base required for eventual commercial recovery of the heavy oils from oil sands and processing these oils to produce synthetic crude oil and other products such as asphalt. The overall program is based on mining the oil sand, processing the mined sand to recover the heavy oils and upgrading them to products. Multiple deposits are being investigated since it is believed that a large scale (approximately 20,000 bbl/day) plant would require the use of resources from more than one deposit. The tasks or projects in the program are organized according to the following classification: Recovery technologies which includes thermal recovery methods, water extraction methods, and solvent extraction methods; upgrading and processing technologies which covers hydrotreating, hydrocracking, and hydropyrolysis; solvent extraction; production of specialty products; and environmental aspects of the production and processing technologies. These tasks are covered in this report.

Treatment of primary tailings and middlings from the hot water extraction process for recovering bitumen from tar sand  

SciTech Connect (OSTI)

The primary tailings and middlings are combined and fed to a vessel having the general form of a deep cone thickener. The feed is deflected outwardly and generally horizontally by a baffle, as it is delivered to the vessel. Simultaneously, the outwardly radiating layer of newly added feed is contacted from below by an upwelling stream of aerated middlings, which stream moves in parallel with the aforesaid layer. Bitumen froth is formed and recovered. The upwelling stream is provided by circulating middlings through eductor/aerator assemblies and a plenum chamber mounted centrally in the body of middlings in the vessel. A generally circular circulation of middlings is generated. In this manner, the newly added bitumen is quickly and efficiently recovered. Recirculation of middlings to the aeration zone yields an additional recovery of bitumen. Use of the deep cone ensures that the tailings from the vessel are relatively low in water and bitumen content.

Microstructural characterization of a Canadian oil sand  

E-Print Network [OSTI]

The microstructure of oil sand samples extracted at a depth of 75 m from the estuarine Middle McMurray formation (Alberta, Canada) has been investigated by using high resolution 3D X-Ray microtomography ($\\mu$CT) and Cryo Scanning Electron Microscopy (CryoSEM). $\\mu$CT images evidenced some dense areas composed of highly angular grains surrounded by fluids that are separated by larger pores full of gas. 3D Image analysis provided in dense areas porosity values compatible with in-situ log data and macroscopic laboratory determinations, showing that they are representative of intact states. $\\mu$CT hence provided some information on the morphology of the cracks and disturbance created by gas expansion. The CryoSEM technique, in which the sample is freeze fractured within the SEM chamber prior to observation, provided pictures in which the (frozen) bitumen clearly appears between the sand grains. No evidence of the existence of a thin connate water layer between grains and the bitumen, frequently mentioned in th...

Evaluation of a subsurface oxygenation technique using colloidal gas aphron injections into packed column reactors  

SciTech Connect (OSTI)

Bioremediation may be a remedial technology capable of decontaminating subsurface environments. The objective of this research was to evaluate the use of colloidal gas aphron (CGA) injection, which is the injection of micrometer-size air bubbles in an aqueous surfactant solution, as a subsurface oxygenation technique to create optimal growth conditions for aerobic bacteria. Along with this, the capability of CGAs to act as a soil-washing agent and free organic components from a coal tar-contaminated matrix was examined. Injection of CGAs may be useful for remediation of underground coal gasification (UCG) sites. Because of this, bacteria and solid material from a UCG site located in northeastern Wyoming were used in this research. Colloidal gas aphrons were generated and pumped through packed column reactors (PCRS) containing post-burn core materials. For comparison, PCRs containing sand were also studied. Bacteria from this site were tested for their capability to degrade phenol, a major contaminant at the UCG site, and were also used to bioaugment the PCR systems. In this study we examined: (1) the effect of CGA injection on dissolved oxygen concentrations in the PCR effluents, (2) the effect of CGA, H{sub 2}O{sub 2}, and phenol injections on bacterial populations, (3) the stability and transport of CGAs over distance, and (4) CGA injection versus H{sub 2}O{sub 2} injection as an oxygenation technique.

Acoustic sand detector for fluid flowstreams  

DOE Patents [OSTI]

The particle volume and particle mass production rate of particulate solids entrained in fluid flowstreams such as formation sand or fracture proppant entrained in oil and gas production flowstreams is determined by a system having a metal probe interposed in a flow conduit for transmitting acoustic emissions created by particles impacting the probe to a sensor and signal processing circuit which produces discrete signals related to the impact of each of the particles striking the probe. The volume or mass flow rate of particulates is determined from making an initial particle size distribution and particle energy distribution and comparing the initial energy distribution and/or the initial size distribution with values related to the impact energies of a predetermined number of recorded impacts. The comparison is also used to recalibrate the system to compensate for changes in flow velocity.

Effect of the bioemulsifier emulsan on naphthalene mineralization from coal tar in aqueous systems  

SciTech Connect (OSTI)

Coal tar in aerobic aqueous systems was treated with purified emulsan, the anionic heteropolysaccharide bioemulsifier produced by Acinetobacter calcoaceticus RAG-1; with inocula of various concentrations of stationary phase RAG-1 cells; or with cell-free broth from stationary phase RAG-1 cultures. Naphthalene mineralization by a mixed PAH-degrading population was measured by recovering {sup 14}CO{sub 2} evolved during biotransformation of the [{sup 14}C]naphthalene-labeled coal tar. There was no evidence of naphthalene mineralization by RAG- 1 cells alone. The addition of emulsan, RAG-1 inocula, or cell-free broth to systems containing the PAH-degrading population did not significantly affect naphthalene mineralization in any of the systems tested. Coal tar in these experiments was present either as a free dense nonaqueous phase liquid (DNAPL), or as DNAPL imbibed into microporous silica particles. Emulsification of the tar was not observed in either case. The presence or absence of microporous silica did not affect the extent or rate of naphthalene mineralization, nor did the concentration of RAG-1 inocula or the amount of broth added. The addition of cell-free broth, emulsan, or RAG-1 cells late in the experiments did not yield significantly different results compared to initial addition of these substances. Thus, emulsan and related fractions from RAG-1 cultures were ineffective in altering naphthalene mineralization in this study.

Fraced horizontal well shows potential of deep tight gas  

SciTech Connect (OSTI)

Successful completion of a multiple fraced, deep horizontal well demonstrated new techniques for producing tight gas sands. In Northwest Germany, Mobil Erdgas-Erdoel GmbH drilled, cased, and fraced the world`s deepest horizontal well in the ultra-tight Rotliegendes ``Main`` sand at 15,687 ft (4,783 m) true vertical depth. The multiple frac concept provides a cost-efficient method to economically produce significant gas resources in the ultra-tight Rotliegendes ``Main`` sand. Besides the satisfactory initial gas production rate, the well established several world records, including deepest horizontal well with multiple fracs, and proved this new technique to develop ultra-tight sands.

Quinoline and derivatives at a tar oil contaminated site: hydroxylated products as indicator for natural attenuation?  

SciTech Connect (OSTI)

LC-MS-MS analysis of groundwater of a tar oil contaminated site (a former coal mine and coking plant in Castrop-Rauxel, Germany) showed the occurrence of the N-heterocycles quinoline and isoquinoline as well as their hydroxylated and hydrogenated metabolites. The concentrations of the hydroxylated compounds, 2(1H)-quinolinone and 1(2H)-isoquinolinone, were significantly higher than those of the nonsubstituted parent compounds. Therefore, exclusive quantification of the parent compounds leads to an underestimation of the amount of N-heterocycles present in the groundwater. Microbial degradation experiments of quinoline and isoquinoline with aquifer material of the site as inocculum showed the formation of hydroxylated and hydrogenated products under sulfate-reducing conditions, the prevailing conditions in the field. However, since analyses of seven tar products showed that these compounds are also primary constituents, their detection in groundwater is found to be a nonsufficient indicator for the occurrence of biological natural attenuation processes. Instead, the ratio of hydroxylated to parent compound (R{sub metabolite}) is proposed as a useful indicator. We found that 65-83% of all groundwater samples showed R{sub metabolite} for 2(1H)-quinolinone, 1(2H)-isoquinolinone, 3,4-dihydro-2(1H)-quinolinone, and 3,4-dihydro-1(2H)-isoquinolinone, which was higher than the highest ratio found in tar products. With respect to the observed partition coefficient between tar oil and water of 3.5 for quinoline and isoquinoline and 0.3 for 2(1H)-quinolinone and 1(2H)-isoquinolinone, the ratio in groundwater would be approximately 10 times higher than the ratio in tar oil. When paying attention to these two parameters, 19-31% of groundwater samples exceed the highest tar oil ratio. This indicates that biological processes take place in the aquifer of the site and R{sub metabolite} is an applicable indicator for natural attenuation. 42 refs., 6 figs., 2 tabs.

Hydraulic conductivity of shaly sands  

SciTech Connect (OSTI)

The effects of clays on the hydraulic conductivity of a sandstone are analyzed by considering a simple clay coating structure for the sand grains. In the model, silicate insulating nuclei are uniformly surrounded by charged clay particles. The total charge on the clays is compensated by a counterion density Q{sub v}. Assuming a capillary flow regime inside this granular model a Kozeny-Carman type equation has been derived, expressing its intrinsic permeability k in terms of a porosity-tortuosity factor {phi}{sup (m{minus}0.5)} and of the parameter Q{sub v}. The power-law derived expression shows that k decreases with the amount of clay, not only because a high Q{sub v} implies a narrowing of the pore channels, but also because it modifies the hydraulic tortuosity of the medium. This new equation has been statistically tested with extensive petrophysical laboratory data for different types of shaly sandstones.

Shock response of dry sand.  

SciTech Connect (OSTI)

The dynamic compaction of sand was investigated experimentally and computationally to stresses of 1.8 GPa. Experiments have been performed in the powder's partial compaction regime at impact velocities of approximately 0.25, 0.5, and 0.75 km/s. The experiments utilized multiple velocity interferometry probes on the rear surface of a stepped target for an accurate measurement of shock velocity, and an impedance matching technique was used to deduce the shock Hugoniot state. Wave profiles were further examined for estimates of reshock states. Experimental results were used to fit parameters to the P-Lambda model for porous materials. For simple 1-D simulations, the P-Lambda model seems to capture some of the physics behind the compaction process very well, typically predicting the Hugoniot state to within 3%.

Relationship of respiratory symptoms and pulmonary function to tar, nicotine, and carbon monoxide yield of cigarettes  

SciTech Connect (OSTI)

The data from consecutive surveys of the Tucson Epidemiologic Study (1981-1988) were used to evaluate the relationship in cigarette smokers of respiratory symptoms and pulmonary function to tar, nicotine, and carbon monoxide (CO) yields of the cigarette. There were 690 subjects who reported smoking regularly in at least one survey, over age 15. After adjustment for intensity and duration of smoking and for depth of inhalation, the risk of chronic phlegm, cough, and dyspnea were not related to the tar and nicotine yields. In 414 subjects with pulmonary function tested in at least one of the three surveys the spirometric indices used were significantly related to the daily dose of tar, nicotine, and CO (product of the cigarette yield and daily number of cigarettes smoked). The effects were more pronounced for past than for current doses. However, the differentiation of pulmonary function due to various yields of cigarettes was small in comparison to the difference in pulmonary function between smokers and nonsmokers.

Unconventional Oil and Gas Resources  

SciTech Connect (OSTI)

World oil use is projected to grow to 98 million b/d in 2015 and 118 million b/d in 2030. Total world natural gas consumption is projected to rise to 134 Tcf in 2015 and 182 Tcf in 2030. In an era of declining production and increasing demand, economically producing oil and gas from unconventional sources is a key challenge to maintaining global economic growth. Some unconventional hydrocarbon sources are already being developed, including gas shales, tight gas sands, heavy oil, oil sands, and coal bed methane. Roughly 20 years ago, gas production from tight sands, shales, and coals was considered uneconomic. Today, these resources provide 25% of the U.S. gas supply and that number is likely to increase. Venezuela has over 300 billion barrels of unproven extra-heavy oil reserves which would give it the largest reserves of any country in the world. It is currently producing over 550,000 b/d of heavy oil. Unconventional oil is also being produced in Canada from the Athabasca oil sands. 1.6 trillion barrels of oil are locked in the sands of which 175 billion barrels are proven reserves that can be recovered using current technology. Production from 29 companies now operating there exceeds 1 million barrels per day. The report provides an overview of continuous petroleum sources and gives a concise overview of the current status of varying types of unconventional oil and gas resources. Topics covered in the report include: an overview of the history of Oil and Natural Gas; an analysis of the Oil and Natural Gas industries, including current and future production, consumption, and reserves; a detailed description of the different types of unconventional oil and gas resources; an analysis of the key business factors that are driving the increased interest in unconventional resources; an analysis of the barriers that are hindering the development of unconventional resources; profiles of key producing regions; and, profiles of key unconventional oil and gas producers.

Phase-equilibria for design of coal-gasification processes: dew points of hot gases containing condensible tars. Final report  

SciTech Connect (OSTI)

This research is concerned with the fundamental physical chemistry and thermodynamics of condensation of tars (dew points) from the vapor phase at advanced temperatures and pressures. Fundamental quantitative understanding of dew points is important for rational design of heat exchangers to recover sensible heat from hot, tar-containing gases that are produced in coal gasification. This report includes essentially six contributions toward establishing the desired understanding: (1) Characterization of Coal Tars for Dew-Point Calculations; (2) Fugacity Coefficients for Dew-Point Calculations in Coal-Gasification Process Design; (3) Vapor Pressures of High-Molecular-Weight Hydrocarbons; (4) Estimation of Vapor Pressures of High-Boiling Fractions in Liquefied Fossil Fuels Containing Heteroatoms Nitrogen or Sulfur; and (5) Vapor Pressures of Heavy Liquid Hydrocarbons by a Group-Contribution Method.

Thailand gas project now operational  

SciTech Connect (OSTI)

Now operational, Phase 1 of Thailand's first major natural gas system comprises one of the world's longest (264 miles) offshore gas lines. Built for the Petroleum Authority of Thailand (PTT), this system delivers gas from the Erawan field in the Gulf of Thailand to two electrical power plants near Bangkok, operated by the Electricity Generating Authority of Thailand (EGAT). The project required laying about 360 miles of pipeline, 34-in., 0.625 in.-thick API-5LX-60 pipe offshore and 28-in., 0.406 in.-thick API-5LX-60 onshore. The offshore pipe received a coal-tar coating, a 3.5-5.0 in. concrete coating, and zinc sacrificial-anode bracelets. The onshore line was coated with the same coal-tar enamel and, where necessary, with concrete up to 4.5 in. thick. Because EGAT's two power plants are the system's only customers, no more pipeline will be constructed until deliveries, currently averaging about 100 million CF/day, reach the 250 million CF/day level. The project's second phase will include additional pipelines as well as an onshore distribution network to industrial customers.

A boron containing burn resistant, low level radiation protection material useful, for example, as a liner for radioactive waste disposal and storage, a component for neutron absorber, and a shield for a neutron source. The material is basically composed of Borax in the range of 25-50%, coal tar in the range of 25-37.5%, with the remainder being an epoxy resin mix. A preferred composition is 50% Borax, 25% coal tar and 25% epoxy resin. The material is not susceptible to burning and is about 1/5 the cost of existing radiation protection material utilized in similar applications.

The monitoring of multiphase flow is an established process that has spanned several decades. This paper demonstrates the use of acoustic emission (AE) technology to investigate sand transport characteristic in three-phase (air-water-sand) flow in a horizontal pipe where the superficial gas velocity (VSG) had a range of between 0.2 ms{sup ?1} to 2.0 ms{sup ?1} and superficial liquid velocity (VSL) had a range of between 0.2 ms{sup ?1} to 1.0 ms{sup ?1}. The experimental findings clearly show a correlation exists between AE energy levels, sand concentration, superficial gas velocity (VSG) and superficial liquid velocity (VSL)

CAVITY LIKE COMPLETIONS IN WEAK SANDS PREFERRED UPSTREAM MANAGEMENT PRACTICES  

SciTech Connect (OSTI)

The technology referred to as Cavity Like Completions (CLC) offers a new technique to complete wells in friable and unconsolidated sands. A successfully designed CLC provides significant increases in well PI (performance index) at lower costs than alternative completion techniques. CLC technology is being developed and documented by a partnership of major oil and gas companies through a GPRI (Global Petroleum Research Institute) joint venture. Through the DOE-funded PUMP program, the experiences of the members of the joint venture will be described for other oil and gas producing companies. To date six examples of CLC completions have been investigated by the JV. The project was performed to introduce a new type of completion (or recompletion) technique to the industry that, in many cases, offers a more cost effective method to produce oil and gas from friable reservoirs. The project's scope of work included: (1) Further develop theory, laboratory and field data into a unified model to predict performance of cavity completion; (2) Perform at least one well test for cavity completion (well provided by one of the sponsor companies); (3) Provide summary of geo-mechanical models for PI increase; and (4) Develop guidelines to evaluate success of potential cavity completion. The project tracks the experiences of a joint industry consortium (GPRI No. 17) over a three year period and compiles results of the activities of this group.

Natural gas represents an important energy source for the United States. According to the U.S. Department of Energy's (DOE's) Energy Information Administration (EIA), about 22% of the country's energy needs are provided by natural gas. Historically, natural gas was produced from conventional vertical wells drilled into porous hydrocarbon-containing formations. During the past decade, operators have increasingly looked to other unconventional sources of natural gas, such as coal bed methane, tight gas sands, and gas shales.

U-GAS process  

SciTech Connect (OSTI)

The Institute of Gas Technology (IGT) has developed an advanced coal gasification process. The U-GAS process has been extensively tested in a pilot plant to firmly establish process feasibility and provide a large data base for scale-up and design of the first commercial plant. The U-GAS process is considered to be one of the more flexible, efficient, and economical coal gasification technologies developed in the US during the last decade. The U-GAS technology is presently available for licensing from GDC, Inc., a wholly-owned subsidiary of IGT. The U-GAS process accomplishes four important functions in a single-stage, fluidized-bed gasifier: It decakes coal, devolatilizes coal, gasifies coal, and agglomerates and separates ash from char. Simultaneously with coal gasification, the ash is agglomerated into spherical particles and separated from the bed. Part of the fluidizing gas enters the gasifier through a sloping grid. The remaining gas flows upward at a high velocity through the ash agglomerating device and forms a hot zone within the fluidized bed. High-ash-content particles agglomerate under these conditions and grow into larger and heavier particles. Agglomerates grow in size until they can be selectively separated and discharged from the bed into water-filled ash hoppers where they are withdrawn as a slurry. In this manner, the fluidized bed achieves the same low level of carbon losses in the discharge ash generally associated with the ash-slagging type of gasifier. Coal fines elutriated from the fluidized bed are collected in two external cyclones. Fines from the first cyclone are returned to the bed and fines from the second cyclone are returned to the ash agglomerating zone, where they are gasified, and the ash agglomerated with bed ash. The raw product gas is virtually free of tar and oils, thus simplifying ensuing heat recovery and purification steps.

Investigation of bonding mechanism of coking on semi-coke from lignite with pitch and tar  

SciTech Connect (OSTI)

In coking, the bonding ability of inert macerals by reactive macerals is dependent on various parameters and also is related to the wettability of the inert macerals. In this study, the effect of carbonization temperature on the wettability of semi-cokes produced at various temperatures has been investigated. Soma and Yatagan semicokes represent inert macerals, and pitch was used as a reactive structure in the experiments. The briquetted pitch blocks were located on the semi-cokes and heated from the softening temperature of pitch (60{sup o}C) to 140{sup o}C to observe the wettability. In addition, liquid tar was also used to determine the wettability of semi-cokes. From the standpoint of wettability, the temperature of 900{sup o}C was determined to be the critical point for coke produced from sub-bituminous coals. 15 refs., 6 figs., 2 tabs.

Well completion process for formations with unconsolidated sands  

DOE Patents [OSTI]

A method for consolidating sand around a well, involving injecting hot water or steam through well casing perforations in to create a cement-like area around the perforation of sufficient rigidity to prevent sand from flowing into and obstructing the well. The cement area has several wormholes that provide fluid passageways between the well and the formation, while still inhibiting sand inflow.

History of development and depositional environment and upper Cherokee Prue Sand, Custer and Roger Mills counties, Oklahoma  

SciTech Connect (OSTI)

In western Oklahoma the uppermost sand member of the Cherokee Group, the True sand, was first drilled and found productive in two discoveries, completed in 1980, in west-central Custer County and in central Roger Mills County, Oklahoma. For 1 1/2 to 2 years these two discoveries, some 18 mi (29 km) apart, were thought to be stratigraphic equivalents of two separate sand bodies occurring parallel to the classic northwest-southeast-trending systems of the Anadarko basin. At present, some 40 productive wells will ultimately produce more than 100 bcf of gas and 3 million bbl of condensate from an average depth of 11,500 ft (3500 m). Sand porosities range from 3 to 18% with most producing wells having porosities in the 12 to 15% range. Because Prue sand is slightly overpressured (a pressure gradient of .53 psi/foot), the reserves are generally better than normal-pressured wells at this depth. The sand body is over 40 mi (64 km) in length, 1 to 1.5 mi (1.6 to 2.4 km) wide, and 60 ft (18 m) thick. Study of the core shows the interval to grade from a medium to fine-grained sand, highly laminated and cross-bedded with black shale, to a slightly coarser grained nonstructured interval and back into a highly laminated cross-bedded sandy black shale interval. The interval is topped by a 10 ft (3 m) thick black shale layer that is a predominant bed throughout the whole area. These conclusions have implications that may assist in the exploration of other Pennsylvanian sands in this area.

Engineering analysis of biomass gasifier product gas cleaning technology  

SciTech Connect (OSTI)

For biomass gasification to make a significant contribution to the energy picture in the next decade, emphasis must be placed on the generation of clean, pollutant-free gas products. This reports attempts to quantify levels of particulated, tars, oils, and various other pollutants generated by biomass gasifiers of all types. End uses for biomass gases and appropriate gas cleaning technologies are examined. Complete systems analysis is used to predit the performance of various gasifier/gas cleanup/end use combinations. Further research needs are identified. 128 refs., 20 figs., 19 tabs.

Three dimensional fabric evolution of sheared sand  

SciTech Connect (OSTI)

Granular particles undergo translation and rolling when they are sheared. This paper presents a three-dimensional (3D) experimental assessment of fabric evolution of sheared sand at the particle level. F-75 Ottawa sand specimen was tested under an axisymmetric triaxial loading condition. It measured 9.5 mm in diameter and 20 mm in height. The quantitative evaluation was conducted by analyzing 3D high-resolution x-ray synchrotron micro-tomography images of the specimen at eight axial strain levels. The analyses included visualization of particle translation and rotation, and quantification of fabric orientation as shearing continued. Representative individual particles were successfully tracked and visualized to assess the mode of interaction between them. This paper discusses fabric evolution and compares the evolution of particles within and outside the shear band as shearing continues. Changes in particle orientation distributions are presented using fabric histograms and fabric tensor.

Site Selection for DOE/JIP Gas Hydrate Drilling in the Northern Gulf of Mexico  

SciTech Connect (OSTI)

In the late spring of 2008, the Chevron-led Gulf of Mexico Gas Hydrate Joint Industry Project (JIP) expects to conduct an exploratory drilling and logging campaign to better understand gas hydrate-bearing sands in the deepwater Gulf of Mexico. The JIP Site Selection team selected three areas to test alternative geological models and geophysical interpretations supporting the existence of potential high gas hydrate saturations in reservoir-quality sands. The three sites are near existing drill holes which provide geological and geophysical constraints in Alaminos Canyon (AC) lease block 818, Green Canyon (GC) 955, and Walker Ridge (WR) 313. At the AC818 site, gas hydrate is interpreted to occur within the Oligocene Frio volcaniclastic sand at the crest of a fold that is shallow enough to be in the hydrate stability zone. Drilling at GC955 will sample a faulted, buried Pleistocene channel-levee system in an area characterized by seafloor fluid expulsion features, structural closure associated with uplifted salt, and abundant seismic evidence for upward migration of fluids and gas into the sand-rich parts of the sedimentary section. Drilling at WR313 targets ponded sheet sands and associated channel/levee deposits within a minibasin, making this a non-structural play. The potential for gas hydrate occurrence at WR313 is supported by shingled phase reversals consistent with the transition from gas-charged sand to overlying gas-hydrate saturated sand. Drilling locations have been selected at each site to 1) test geological methods and models used to infer the occurrence of gas hydrate in sand reservoirs in different settings in the northern Gulf of Mexico; 2) calibrate geophysical models used to detect gas hydrate sands, map reservoir thicknesses, and estimate the degree of gas hydrate saturation; and 3) delineate potential locations for subsequent JIP drilling and coring operations that will collect samples for comprehensive physical property, geochemical and other analyses.

Policy Analysis of the Canadian Oil Sands Experience  

SciTech Connect (OSTI)

For those who support U.S. oil sands development, the Canadian oil sands industry is often identified as a model the U.S. might emulate, yielding financial and energy security benefits. For opponents of domestic oil sands development, the Canadian oil sands experience illustrates the risks that opponents of development believe should deter domestic policymakers from incenting U.S. oil sands development. This report does not seek to evaluate the particular underpinnings of either side of this policy argument, but rather attempts to delve into the question of whether the Canadian experience has relevance as a foundational model for U.S. oil sands development. More specifically, this report seeks to assess whether and how the Canadian oil sands experience might be predictive or instructive in the context of fashioning a framework for a U.S. oil sands industry. In evaluating the implications of these underpinnings for a prospective U.S. oil sands industry, this report concentrates on prospective development of the oil sands deposits found in Utah.

Biomass Gas Cleanup Using a Therminator  

SciTech Connect (OSTI)

The objective of the project is to develop and demonstrate a novel fluidized-bed process module called a �¢����Therminator�¢��� to simultaneously destroy and/or remove tar, NH3 and H2S from raw syngas produced by a fluidized-bed biomass gasifier. The raw syngas contains as much as 10 g/m3 of tar, 4,000 ppmv of NH3 and 100 ppmv of H2S. The goal of the Therminator module would be to use promising regenerable catalysts developed for removing tar, ammonia, and H2S down to low levels (around 10 ppm). Tars are cracked to a non-condensable gas and coke that would deposit on the acid catalyst. We will deposit coke, much like a fluid catalytic cracker (FCC) in a petroleum refinery. The deposited coke fouls the catalyst, much like FCC, but the coke would be burned off in the regenerator and the regenerated catalyst would be returned to the cracker. The rapid circulation between the cracker and regenerator would ensure the availability of the required amount of regenerated catalyst to accomplish our goal. Also, by removing sulfur down to less than 10 ppmv, NH3 decomposition would also be possible in the cracker at 600-700���°C. In the cracker, tar decomposes and lays down coke on the acid sites of the catalyst, NH3 is decomposed using a small amount of metal (e.g., nickel or iron) catalyst incorporated into the catalyst matrix, and H2S is removed by a small amount of a metal oxide (e.g. zinc oxide or zinc titanate) by the H2S-metal oxide reaction to form metal sulfide. After a tolerable decline in activity for these reactions, the catalyst particles (and additives) are transported to the regenerator where they are exposed to air to remove the coke and to regenerate the metal sulfide back to metal oxide. Sulfate formation is avoided by running the regeneration with slightly sub-stoichiometric quantity of oxygen. Following regeneration, the catalyst is transported back to the cracker and the cycling continues. Analogous to an FCC reactor system, rapid cycling will allow the use of very active cracking catalysts that lose activity due to coking within the order of several seconds.

TESTING OF TMR SAND MANTIS FINAL REPORT  

SciTech Connect (OSTI)

Screening tests of Sand Mantis candidate materials selected for erosion resistance have been completed. The results of this testing identified that over a relatively short period of operation (<1 hour), measurable erosion will occur in each of the candidate zoom tube materials given equal operating exposure. Additionally, this testing has shown that erosion of the rubber discharge hose directly downstream of the vehicle could be expected to limit the service life of the discharge hose. On the basis of these test results, SRNL recommends the following; {lg_bullet} redesign of critical system components (e.g., zoom tube, discharge hose) should be conducted to improve system characteristics relative to erosion and capitalize on the results of this testing, {lg_bullet} continued efforts to deploy the Sand Mantis should include testing to better define and optimize operating parameters, and gain an understanding of system dynamics, {lg_bullet} discontinue wear testing with the selected materials pending redesign of critical system components (1st recommendation) and inclusion of other candidate materials. The final selection of additional candidate materials should be made following design changes, but might include a Stellite alloy or zirconia.

Diamonds in the rough: identification of individual napthenic acids in oil sands process water  

SciTech Connect (OSTI)

Expansion of the oil sands industry of Canada has seen a concomitant increase in the amount of process water produced and stored in large lagoons known as tailings ponds. Concerns have been raised, particularly about the toxic complex mixtures of water-soluble naphthenic acids (NA) in the process water. To date, no individual NA have been identified, despite numerous attempts, and while the toxicity of broad classes of acids is of interest, toxicity is often structure-specific, so identification of individual acids may also be very important. The chromatographic resolution and mass spectral identification of some individual NA from oil sands process water is described. The authors concluded that the presence of tricyclic diamondoid acids, never before even considered as NA, suggests an unprecedented degree of biodegradation of some of the oil in the oil sands. The identifications reported should now be followed by quantitative studies, and these used to direct toxicity assays of relevant NA and the method used to identify further NA to establish which, or whether all NA, are toxic. The two-dimensional comprehensive gas chromatography-mass spectrometry method described may also be important for helping to better focus reclamation/remediation strategies for NA as well as in facilitating the identification of the sources of NA in contaminated surface waters (auth)

Vapor pressures and heats of vaporization of primary coal tars. Quarterly technical progress report, 1 July 1993--30 September 1993  

SciTech Connect (OSTI)

There is significant current interest in general area of coal pyrolysis, particularly with respect to comprehensive models of this complicated phenomenon. This interest derives from the central role of pyrolysis in all thermally driven coal conversion processes -- gasification, combustion, liquefaction, mild gasification, or thermal benefication. There remain several key data needs in these application areas. Among them is a need for more reliable correlation for prediction of vapor pressure of heavy, primary coal tars. Such information is important in design of all coal conversion processes, in which the volatility of tarry products is of major concern. Only very limited correlations exist, and these are not considered reliable to even an order of magnitude when applied to tars. The present project seeks to address this important gap in the near term by direct measurement of vapor pressures of coal tar fractions, by application of well-established techniques and modifications thereof. The principal objectives of the program are to: (1) obtain data on the vapor pressures and heats of vaporization of tars from a range of ranks of coal, (2) develop correlations based on a minimum set of conveniently measurable characteristics of the tars, (3) develop equipment that would allow performing such measurements in a reliable, straightforward fashion. Results of the literature survey are compiled. The experimental tasks have been concerned with setup and calibration.

Recovery of bitumen from oil sand by steam with chemicals  

SciTech Connect (OSTI)

Recently, oil sand bitumen has become the center of attention as a possible oil energy substitute for the future. Until now, the development of oil sand has been performed by surface miing and conventional steam injection, these methods are limited in respect to resource recovery. A more effective method needs to be developed utilizing in situ recovery. In this study, a new attempt is made for the purpose of enhancing the recovery of bitumen from oil sand by adopting the method of injecting high pressure steam and chemicals such as solvents, surfactants, and others.

Aging effects on oil-contaminated Kuwaiti sand  

SciTech Connect (OSTI)

Large quantities of oil-contaminated sands resulted from the destruction of oil wells and the formation of oil lakes in Kuwait at the end of the Gulf Wa/r. A laboratory testing program was carried out to determine the geotechnical properties of this material and the effect of aging on their properties. Tests included direct shear, triaxial, and consolidation tests on clean and contaminated sand at the same relative density. The influence of aging was examined by testing uncontaminated sand after aging for one, three, and six months in natural environmental conditions. The results indicated increased strength and stiffness due to aging and a reduction of the oil content due to evaporation of volatile compounds. The factors that influence the depth of oil penetration in compacted sand columns were also examined including the type of oil, relative density, and the amount of fines.

Separation of anthracene from crude anthracene using gas antisolvent recrystallization  

SciTech Connect (OSTI)

Pure anthracene is mostly used for conversion to anthraquinone, an intermediate for the synthesis of very powerful vat dyestuffs. A coal tar distillate, crude anthracene, which contains 30% anthracene, 25% phenanthrene, 15% carbazole, and other impurities, was used as the model mixture. In this study, 90% by weight purity anthracene was obtained using gas antisolvent (GAS) recrystallization. The GAS process induces the separation of solids by introducing an antisolvent, carbon dioxide (or the supercritical fluid), into acetone which was used as the liquid solvent. The dissolution of the compressed gas into the solute-laden solution selectively lowers the solubilities of solid solutes and salts them out. The results showed that high purity anthracene was obtained at a high feed concentration and high pressure conditions. The separation factor of anthracene versus phenanthrene is close to 30.07.

The report explains the current and potential of the unconventional gas market including country profiles, major project case studies, and new technology research. It identifies the major players in the market and reports their current and forecasted projects, as well as current volume and anticipated output for specific projects. Contents are: Overview of unconventional gas; Global natural gas market; Drivers of unconventional gas sources; Forecast; Types of unconventional gas; Major producing regions Overall market trends; Production technology research; Economics of unconventional gas production; Barriers and challenges; Key regions: Australia, Canada, China, Russia, Ukraine, United Kingdom, United States; Major Projects; Industry Initiatives; Major players. Uneconomic or marginally economic resources such as tight (low permeability) sandstones, shale gas, and coalbed methane are considered unconventional. However, due to continued research and favorable gas prices, many previously uneconomic or marginally economic gas resources are now economically viable, and may not be considered unconventional by some companies. Unconventional gas resources are geologically distinct in that conventional gas resources are buoyancy-driven deposits, occurring as discrete accumulations in structural or stratigraphic traps, whereas unconventional gas resources are generally not buoyancy-driven deposits. The unconventional natural gas category (CAM, gas shales, tight sands, and landfill) is expected to continue at double-digit growth levels in the near term. Until 2008, demand for unconventional natural gas is likely to increase at an AAR corresponding to 10.7% from 2003, aided by prioritized research and development efforts. 1 app.

Geotechnical properties of oil-contaminated Kuwaiti sand  

SciTech Connect (OSTI)

Large quantities of oil-contaminated sands resulted from exploded oil wells, burning oil fires, the destruction of oil storage tanks, and the formation of oil lakes in Kuwait at the end of the Gulf War. An extensive laboratory testing program was carried out to determine the geotechnical characteristics of this material. Testing included basic properties, compaction and permeability tests, and triaxial and consolidation tests on clean and contaminated sand at the same relative density. Contaminated specimens were prepared by mixing the sand with oil in the amount of 6% by weight or less to match field conditions. The influence of the type of oil, and relative density was also investigated by direct shear tests. The results indicated a small reduction in strength and permeability and an increase in compressibility due to contamination. The preferred method of disposal of this material is to use it as a stabilizing material for other projects such as road construction.

Investigation of guided waves propagation in pipe buried in sand  

SciTech Connect (OSTI)

The inspection of pipelines by guided wave testing is a well-established method for the detection of corrosion defects in pipelines, and is currently used routinely in a variety of industries, e.g. petrochemical and energy. When the method is applied to pipes buried in soil, test ranges tend to be significantly compromised because of attenuation of the waves caused by energy radiating into the soil. Moreover, the variability of soil conditions dictates different attenuation characteristics, which in-turn results in different, unpredictable, test ranges. We investigate experimentally the propagation and attenuation characteristics of guided waves in pipes buried in fine sand using a well characterized full scale experimental apparatus. The apparatus consists of an 8 inch-diameter, 5.6-meters long steel pipe embedded over 3 meters of its length in a rectangular container filled with fine sand, and an air-bladder for the application of overburden pressure. Longitudinal and torsional guided waves are excited in the pipe and recorded using a transducer ring (Guided Ultrasonics Ltd). Acoustic properties of the sand are measured independently in-situ and used to make model predictions of wave behavior in the buried pipe. We present the methodology and the systematic measurements of the guided waves under a range of conditions, including loose and compacted sand. It is found that the application of overburden pressure modifies the compaction of the sand and increases the attenuation, and that the measurement of the acoustic properties of sand allows model prediction of the attenuation of guided waves in buried pipes with a high level of confidence.

Pilot-plant-scale demonstration of an upgrading/refining scheme to convert bitumen or heavy crude oil into high yields of specification-quality aviation turbine fuel was performed. An atmospheric residue from San Ardo (California) crude was converted under hydrovisbreaking conditions to synthetic crude for further refining. Naphtha cuts from the straight run and synthetic crude were combined, catalytically hydrotreated, then hydrocracked. Products from these operations were combined to produce two prototype specification fuels (JP-4 and JP-8) as well as two heavier, variable-quality fuels. An engineering design (Volume II) was developed for a 50,000 BPSD grass-roots refinery, from the pilot-plant operations. Capital investment and operating costs were estimated, and fuel manufacturing costs projected. Conclusions and recommendations for further work are included.

Gas Production from Hydrate-Bearing Sediments - Emergent Phenomena -  

SciTech Connect (OSTI)

Even a small fraction of fine particles can have a significant effect on gas production from hydrate-bearing sediments and sediment stability. Experiments were conducted to investigate the role of fine particles on gas production using a soil chamber that allows for the application of an effective stress to the sediment. This chamber was instrumented to monitor shear-wave velocity, temperature, pressure, and volume change during CO{sub 2} hydrate formation and gas production. The instrumented chamber was placed inside the Oak Ridge National Laboratory Seafloor Process Simulator (SPS), which was used to control the fluid pressure and temperature. Experiments were conducted with different sediment types and pressure-temperature histories. Fines migrated within the sediment in the direction of fluid flow. A vuggy structure formed in the sand; these small cavities or vuggs were precursors to the development of gas-driven fractures during depressurization under a constant effective stress boundary condition. We define the critical fines fraction as the clay-to-sand mass ratio when clays fill the pore space in the sand. Fines migration, clogging, vugs, and gas-driven fracture formation developed even when the fines content was significantly lower than the critical fines fraction. These results show the importance of fines in gas production from hydrate-bearing sediments, even when the fines content is relatively low.

Methane hydrate distribution from prolonged and repeated formation in natural and compacted sand samples: X-ray CT observations  

SciTech Connect (OSTI)

To study physical properties of methane gas hydrate-bearing sediments, it is necessary to synthesize laboratory samples due to the limited availability of cores from natural deposits. X-ray computed tomography (CT) and other observations have shown gas hydrate to occur in a number of morphologies over a variety of sediment types. To aid in understanding formation and growth patterns of hydrate in sediments, methane hydrate was repeatedly formed in laboratory-packed sand samples and in a natural sediment core from the Mount Elbert Stratigraphic Test Well. CT scanning was performed during hydrate formation and decomposition steps, and periodically while the hydrate samples remained under stable conditions for up to 60 days. The investigation revealed the impact of water saturation on location and morphology of hydrate in both laboratory and natural sediments during repeated hydrate formations. Significant redistribution of hydrate and water in the samples was observed over both the short and long term.

Shredded tires and rubber-sand as lightweight backfill  

SciTech Connect (OSTI)

The growing interest in utilizing waste materials in civil engineering applications has opened the possibility of constructing reinforced soil structures with unconventional backfills. Scrap tires are a high-profile waste material for which several uses have been studied, including the use of shredded tires as backfill. A triaxial testing program was conducted to investigate the stress-strain relationship and strength of tire chips and a mixture of sand and tire chips. The test results and additional information from the literature were used in the numerical modeling of wall backfills, both unreinforced and reinforced with geosynthetics. The numerical modeling results suggest tire shreds, particularly when mixed with sand, may be effectively used as a backfill.

Potential for substitution of geothermal energy at domestic defense installations and White Sands Missile Range  

SciTech Connect (OSTI)

Geothermal resources that might provide substitute energy at any of 76 defense installations are identified and evaluated. The geologic characteristics and related economics of potential geothermal resources located at or near the 76 installations were estimated. The geologic assessment identified 18 installations with possible geothermal resources and 4 Atlantic Coastal Plain resource configurations that represented the alternatives available to East Coast bases. These 18 locations and 4 resource configurations, together with 2 possible resources at the White Sands Missile Range and a potential resource at Kings Bay, Georgia, were examined to determine the relative economics of substituting potential geothermal energy for part or all of the existing oil, gas, and electrical energy usage. Four of the military installations - Mountain Home, Norton, Hawthorne, and Sierra - appear to be co-located with possible geothermal resources which, if present, might provide substitute energy at or below current market prices for oil. Six additional locations - Ellsworth, Luke, Williams, Bliss, Fallon, and Twentynine Palms - could become economically attractive under certain conditions. No geothermal resource was found to be economically competitive with natural gas at current controlled prices. Generation of electric power at the locations studied is estimated to be uneconomic at present.

SciTech Connect (OSTI)

The behavior of geopressured reservoirs was investigated by drilling and producing a well in small, well defined, geopressured reservoir; and performing detailed pressure transient analysis together with geological, geophysical, chemical, and physical studies. The Dow-DOE L. R. Sweezy No. 1 well was drilled to a depth of 13,600 feet in Parcperdue field, just south of Lafayette, Louisiana, and began production in April, 1982. The production zone was a poorly consolidated sandstone which constantly produced sand into the well stream, causing damage to equipment and causing other problems. The amount of sand production was kept manageable by limiting the flow rate to below 10,000 barrels per day. Reservoir properties of size, thickness, depth, temperature, pressure, salinity, porosity, and permeability were close to predicted values. The reservoir brine was undersaturated with respect to gas, containing approximately 20 standard cubic feet of gas per barrel of brine. Shale dewatering either did not occur or was insignificant as a drive mechanism. Production terminated when the gravel-pack completion failed and the production well totally sanded in, February, 1983. Total production up to the sanding incident was 1.94 million barrels brine and 31.5 million standard cubic feet gas.

Driver Production proposes to conduct a gas repressurization/well stimulation project on a six well, 80-acre portion of the Dutcher Sand of the East Edna Field, Okmulgee County, Oklahoma. The site has been location of previous successful flue gas injection demonstration but due to changing economic and sales conditions, finds new opportunities to use associated natural gas that is currently being vented to the atmosphere to repressurize the reservoir to produce additional oil. The established infrastructure and known geological conditions should allow quick startup and much lower operating costs than flue gas. Lessons learned from the previous project, the lessons learned form cyclical oil prices and from other operators in the area will be applied. Technology transfer of the lessons learned from both projects could be applied by other small independent operators.

Wet powder seal for gas containment  

DOE Patents [OSTI]

A gas seal is formed by a compact layer of an insoluble powder and liquid filling the fine interstices of that layer. The smaller the particle size of the selected powder, such as sand or talc, the finer will be the interstices or capillary spaces in the layer and the greater will be the resulting sealing capacity, i.e., the gas pressure differential which the wet powder layer can withstand. Such wet powder seal is useful in constructing underground gas reservoirs or storage cavities for nuclear wastes as well as stopping leaks in gas mains buried under ground or situated under water. The sealing capacity of the wet powder seal can be augmented by the hydrostatic head of a liquid body established over the seal.

Proper design hikes gas-lift system efficiency  

SciTech Connect (OSTI)

Proper design of gas-lift pumping systems, used for pumping corrosive or erosive fluids, involves the correct selection of submergence ratio, flow regime, pipe diameter, and physical properties of the fluid. Correlations for maximum lifting efficiency on a friction-free basis vs. submergence ratio have been developed based on experimental data. The Oshinowo and Charles flow map for vertical upward flow has been chosen for determining the two-phase flow regimes. For large-diameter gas-lifting systems, the effects of fluid physical properties on the maximum lifting efficiency become diminished. Gas-lift pumping systems are widely used in the process industry as well as in oil and gas production. In an ethylene dichloride/vinyl chloride monomer (EDC/VCM) plant, quench column bottoms are recirculated back to the column by gas lift of the EDC/VCM stream from the EDC pyrolysis furnace. Gas lift is utilized instead of pumps to alleviate the plugging and erosion problems caused by the presence of coke/tar particulates. Other process applications include those where pumps suffer severe corrosion from the fluids pumped.

Assessment of the KE Basin Sand Filter Inventory In Support of Hazard Categorization  

SciTech Connect (OSTI)

In 1978, the water cleaning system for the KE Basin was upgraded by adding a sand filter and ion exchange columns. Basin water containing finely divided solids is collected by three surface skimmers and pumped to the sand filter. Filtrate from the sand filter is further treated in the ion exchange modules. The suspended solids accumulate in the sand until the pressure drop across the filter reaches established operating limits, at which time the sand filter is backwashed. The backwash is collected in the NLOP, where the solids are allowed to settle as sludge. Figure 2-1 shows a basic piping and instrumentation diagram depicting the relationship among the basin skimmers, sand filter, and NLOP. During the course of deactivation and decommissioning (D&D) of the K-Basins, the sand filter and its media will need to be dispositioned. The isotopic distribution of the sludge in the sand filter has been estimated in KE Basin Sand Filter Monolith DQO (KBC-24705). This document estimates the sand filter contribution to the KE hazard categorization using the data from the DQO.

Determining sand-body geometries for waterflood reservoirs: Examples from Oklahoma  

SciTech Connect (OSTI)

Waterflood projects require an accurate knowledge of reservoir geometry and well-to-well continuity. However, sandstones with thin, multiple-pay zones can be extremely difficult to correlate with confidence. Two case studies of Pennsylvanian sandstones in Oklahoma illustrate how a model for the depositional history of such reservoirs can be an effective tool for determining reservoir continuity. In contrast, correlation criteria such as similar wireline log signatures and relative sand-body thicknesses are not reliable in many situations. In Southwest Logan field (Beaver County), 5 to 15-ft thick reservoir sands formed as shallow marine sand ridges. Their dimensions were approximated from height-to-width ratios of modern sand ridges. Then the reservoir sands were mapped using wireline logs and core data. Individual reservoir sands were approximately 1-2 km wide and stacked en echelon vertically. Thus, a line-drive waterflood pattern oriented parallel to the axes of the ridges is recommended. Tatums field (Carter County) consists of 5 to 50-ft thick sandstones deposited in various deltaic environments. Distributary channel sands have good continuity downdip, but are narrow and lenticular across depositional strike. Crevasse splay and other bay-fill sands were deposited marginal to the channels and are extremely discontinuous. This depositional model can be used to improve flood patterns for these sands, leading to improved sweep efficiency. In both examples, for effective mapping, the depositional facies models have been used to register reservoir quality and wireline log signatures.

Geologic report on the Sand Wash Drilling Project, Moffat and Routt Counties, Colorado  

SciTech Connect (OSTI)

The Sand Wash Basin Drilling Project comprises twenty-seven (27) drill holes located in Moffat and Routt Counties, northwest Colorado, having an aggregate depth of 26,107.5 feet (7957.6 m). The holes penetrate the Browns Park Formation of Miocene age, which is a tuffaceous continental sandstone deposited in fluvial, eolian, and lacustrine environments. Partly based on project drilling results, uranium potential resource estimates for this formation in the $50/lb U/sub 3/O/sub 8/ forward-cost category have been increased by 34,476 tons U/sub 3/O/sub 8/ (35,036 metric tons). Three areas between Maybell and Craig, Colorado, considered favorable for uranium occurrences were verified as favorable by project drilling, and a fourth favorable area northwest of Maybell has been expanded. In addition, project drilling results indicate two new favorable areas, one north and northwest and one south of Steamboat Springs, Colorado. Anomalous radioactivity was detected in drill holes in all six study areas of the project. The most important factor in concentrating significant amounts of uranium in the target formation appears to be the availability of gaseous or liquid hydrocarbons and/or hydrogen sulfide gas as reductants. Where subjacent formations supply these reductants to the Browns Park Formation, project drilling encountered 0.05 percent to 0.01 percent uranium concentrations. Potential, though unproven, sources of these reductants are believed to underlie parts of all six project study areas.

SciTech Connect (OSTI)

Using primarily local personnel and materials, Bredero Price International's Thai pipe-coating plant has prepared some 374 miles of 34 and 28-in. pipe for service in the Gulf of Thailand gas-pipeline project. The enamel-coating shop cleaned, primed and coated all the pipe with coal-tar enamel, glass-fiber mat, felt, and a kraft-paper outer wrap; the cement-coating facility then added a concrete-weight coating to the portion of the pipe earmarked for offshore duty. Scheduled for a 1981 completion, the pipeline will initially carry 250 million CF/day to power-generating plants in Bangpakong and South Bangkok; the volume transported will eventually reach 500 million CF/day when addition offshore production is tied in to the line and an offshore compressor station added.

Coal (or other carbonaceous matter, such as biomass) is converted into a duct gas that is substantially free from hydrocarbons. The coal is fed into a solar reactor (10), and solar energy (20) is directed into the reactor onto coal char, creating a gasification front (16) and a pyrolysis front (12). A gasification zone (32) is produced well above the coal level within the reactor. A pyrolysis zone (34) is produced immediately above the coal level. Steam (18), injected into the reactor adjacent to the gasification zone (32), reacts with char to generate product gases. Solar energy supplies the energy for the endothermic steam-char reaction. The hot product gases (38) flow from the gasification zone (32) to the pyrolysis zone (34) to generate hot char. Gases (38) are withdrawn from the pyrolysis zone (34) and reinjected into the region of the reactor adjacent the gasification zone (32). This eliminates hydrocarbons in the gas by steam reformation on the hot char. The product gas (14) is withdrawn from a region of the reactor between the gasification zone (32) and the pyrolysis zone (34). The product gas will be free of tar and other hydrocarbons, and thus be suitable for use in many processes.

Polymer treatments for D Sand water injection wells: Sooner D Sand Unit Weld County, Colorado. Final report, April 1997  

SciTech Connect (OSTI)

Polymer-gel treatments in injection wells were evaluated for improving sweep efficiency in the D Sandstone reservoir at the Sooner Unit, Weld County, Colorado. Polymer treatments of injection wells at the Sooner Unit were expected to improve ultimate recovery by 1.0 percent of original-oil-in-place of 70,000 bbl of oil. The Sooner D Sand Unit was a demonstration project under the US Department of Energy Class I Oil Program from which extensive reservoir data and characterization were obtained. Thus, successful application of polymer-gel treatments at the Sooner Unit would be a good case-history example for other operators of waterfloods in Cretaceous sandstone reservoirs in the Denver Basin.

Fluid-Bed Testing of Greatpoint Energy's Direct Oxygen Injection Catalytic Gasification Process for Synthetic Natural Gas and Hydrogen Coproduction Year 6 - Activity 1.14 - Development of a National Center for Hydrogen Technology  

SciTech Connect (OSTI)

The GreatPoint Energy (GPE) concept for producing synthetic natural gas and hydrogen from coal involves the catalytic gasification of coal and carbon. GPE’s technology “refines” coal by employing a novel catalyst to “crack” the carbon bonds and transform the coal into cleanburning methane (natural gas) and hydrogen. The GPE mild “catalytic” gasifier design and operating conditions result in reactor components that are less expensive and produce pipeline-grade methane and relatively high purity hydrogen. The system operates extremely efficiently on very low cost carbon sources such as lignites, subbituminous coals, tar sands, petcoke, and petroleum residual oil. In addition, GPE’s catalytic coal gasification process eliminates troublesome ash removal and slagging problems, reduces maintenance requirements, and increases thermal efficiency, significantly reducing the size of the air separation plant (a system that alone accounts for 20% of the capital cost of most gasification systems) in the catalytic gasification process. Energy & Environmental Research Center (EERC) pilot-scale gasification facilities were used to demonstrate how coal and catalyst are fed into a fluid-bed reactor with pressurized steam and a small amount of oxygen to “fluidize” the mixture and ensure constant contact between the catalyst and the carbon particles. In this environment, the catalyst facilitates multiple chemical reactions between the carbon and the steam on the surface of the coal. These reactions generate a mixture of predominantly methane, hydrogen, and carbon dioxide. Product gases from the process are sent to a gas-cleaning system where CO{sub 2} and other contaminants are removed. In a full-scale system, catalyst would be recovered from the bottom of the gasifier and recycled back into the fluid-bed reactor. The by-products (such as sulfur, nitrogen, and CO{sub 2}) would be captured and could be sold to the chemicals and petroleum industries, resulting in near-zero hazardous air or water pollution. This technology would also be conducive to the efficient coproduction of methane and hydrogen while also generating a relatively pure CO{sub 2} stream suitable for enhanced oil recovery (EOR) or sequestration. Specific results of bench-scale testing in the 4- to 38-lb/hr range in the EERC pilot system demonstrated high methane yields approaching 15 mol%, with high hydrogen yields approaching 50%. This was compared to an existing catalytic gasification model developed by GPE for its process. Long-term operation was demonstrated on both Powder River Basin subbituminous coal and on petcoke feedstocks utilizing oxygen injection without creating significant bed agglomeration. Carbon conversion was greater than 80% while operating at temperatures less than 1400°F, even with the shorter-than-desired reactor height. Initial designs for the GPE gasification concept called for a height that could not be accommodated by the EERC pilot facility. More gas-phase residence time should allow the syngas to be converted even more to methane. Another goal of producing significant quantities of highly concentrated catalyzed char for catalyst recovery and material handling studies was also successful. A Pd–Cu membrane was also successfully tested and demonstrated to produce 2.54 lb/day of hydrogen permeate, exceeding the desired hydrogen permeate production rate of 2.0 lb/day while being tested on actual coal-derived syngas that had been cleaned with advanced warm-gas cleanup systems. The membranes did not appear to suffer any performance degradation after exposure to the cleaned, warm syngas over a nominal 100-hour test.

Efficiency Improvement Opportunities for Light-Duty Natural-Gas-Fueled Vehicles  

SciTech Connect (OSTI)

The purpose of this report is to evaluate and make recommendations concerning technologies that promise to improve the efilciency of compressed natural gas (CNG) light-duty vehicles. Technical targets for CNG automotive technology given in the March 1998 OffIce of Advanced Automotive Technologies research and development plan were used as guidance for this effort. The technical target that necessitates this current study is to validate technologies that enable CNG light vehicles to have at least 10% greater - fuel economy (on a miles per gallon equivalent basis) than equivalent gasoline vehicles by 2006. Other tar- gets important to natural gas (NG) automotive technology and this study are to: (1) increase CNG vehicle range to 380 miles, (2) reduce the incremental vehicle cost (CNG vs gasoline) to $1500, and (3) meet the California ultra low-emission vehicle (ULEV) and Federal Tier 2 emission standards expected to be in effect in 2004.

Gas treatment and by-products recovery of Thailand`s first coke plant  

SciTech Connect (OSTI)

Coke is needed in the blast furnace as the main fuel and chemical reactant and the main product of a coke plant. The second main product of the coke plant is coke oven gas. During treatment of the coke oven gas some coal chemicals like tar, ammonia, sulphur and benzole can be recovered as by-products. Since the market prices for these by-products are rather low and often erratic it does not in most cases justify the investment to recover these products. This is the reason why modern gas treatment plants only remove those impurities from the crude gas which must be removed for technical and environmental reasons. The cleaned gas, however, is a very valuable product as it replaces natural gas in steel work furnaces and can be used by other consumers. The surplus can be combusted in the boiler of a power plant. A good example for an optimal plant layout is the new coke oven facility of Thai Special Steel Industry (TSSI) in Rayong. The paper describes the TSSI`s coke oven gas treatment plant.

Geology of new Springdale gas field in northeastern Kansas  

SciTech Connect (OSTI)

The Springdale gas field in Leavenworth County, Kansas, is east of the old McLouth and north of the old Ackerland/Jarbolo fields, both now used for gas storage. Gas production from McLouth sand bodies and the Burgess sand in the Cherokee Group (Pennsylvanian) ranges from 1350 to 1400 ft and extends to the nearby Great Kansas City area. Gas pressures range from 350 to 500 psi and open-flow tests produced up to 675 MCFGD. Structurally, the better wells are high on the flanks of a paleovalley opening toward the north. This structure is reflected on the erosional surface of the Mississippian rocks below and is preserved in the now-deformed base of the Kansas City Group of rocks. The Springdale field is only one of several new Pennsylvanian gas fields in Leavenworth, Wyandotte, and Johnson Counties, Kansas, that are currently commercial. These fields serve as a good example of opening a new frontier in an old area.

Stability of nickel-coated sand as gravel-pack material for thermal wells  

SciTech Connect (OSTI)

Laboratory flow tests have been carried out to study the stability of various nickel-coated sands under aqueous steam temperature and pH conditions that may exist in thermal recovery operations. Other gravel-pack materials tested include Ottawa sand, sintered bauxite, cement clinker, zirconium oxide, and nickel pellets. A comparison was made between the performances of these materials after exposure to identical thermal and hydrolytic conditions. Test results indicate that nickel-coated sands are highly resistant to dissolution at temperatures as high as 300/sup 0/C (570/sup 0/F) and to solution pH's from 4.75 to 11. Weight losses measured after a 72-hour period were less than 1%. In contrast, weight losses from sintered bauxite, zirconium oxide, and Ottawa sand dissolution tests were 30 to 70 times higher under the same conditions. Cement clinker losses were in the intermediate range under alkaline conditions. API standard crushing and acid-solubility tests for proppants also were performed on nickel-coated sands. These results were favorable in that they exceeded the recommended standards. This study of nickel-coated sand stability and mechanical strength has demonstrated its high potential for application as either a gravel-pack material or proppant in thermal recovery operations.

Dynamic Behavior of Sand: Annual Report FY 11  

SciTech Connect (OSTI)

Currently, design of earth-penetrating munitions relies heavily on empirical relationships to estimate behavior, making it difficult to design novel munitions or address novel target situations without expensive and time-consuming full-scale testing with relevant system and target characteristics. Enhancing design through numerical studies and modeling could help reduce the extent and duration of full-scale testing if the models have enough fidelity to capture all of the relevant parameters. This can be separated into three distinct problems: that of the penetrator structural and component response, that of the target response, and that of the coupling between the two. This project focuses on enhancing understanding of the target response, specifically granular geomaterials, where the temporal and spatial multi-scale nature of the material controls its response. As part of the overarching goal of developing computational capabilities to predict the performance of conventional earth-penetrating weapons, this project focuses specifically on developing new models and numerical capabilities for modeling sand response in ALE3D. There is general recognition that granular materials behave in a manner that defies conventional continuum approaches which rely on response locality and which degrade in the presence of strong response nonlinearities, localization, and phase gradients. There are many numerical tools available to address parts of the problem. However, to enhance modeling capability, this project is pursuing a bottom-up approach of building constitutive models from higher fidelity, smaller spatial scale simulations (rather than from macro-scale observations of physical behavior as is traditionally employed) that are being augmented to address the unique challenges of mesoscale modeling of dynamically loaded granular materials. Through understanding response and sensitivity at the grain-scale, it is expected that better reduced order representations of response can be formulated at the continuum scale as illustrated in Figure 1 and Figure 2. The final result of this project is to implement such reduced order models in the ALE3D material library for general use.

FIELD TESTING & OPTIMIZATION OF CO2/SAND FRACTURING TECHNOLOGY  

SciTech Connect (OSTI)

These contract efforts involved the demonstration of a unique liquid free stimulation technology which was, at the beginning of these efforts, in 1993 unavailable in the US. The process had been developed, and patented in Canada in 1981, and held promise for stimulating liquid sensitive reservoirs in the US. The technology differs from that conventionally used in that liquid carbon dioxide (CO{sub 2}), instead of water is the base fluid. The CO{sub 2} is pumped as a liquid and then vaporizes at reservoir conditions, and because no other liquids or chemicals are used, a liquid free fracture is created. The process requires a specialized closed system blender to mix the liquid CO{sub 2} with proppant under pressure. These efforts were funded to consist of up to 21 cost-shared stimulation events. Because of the vagaries of CO{sub 2} supplies, service company support and operator interest only 19 stimulation events were performed in Montana, New Mexico, and Texas. Final reports have been prepared for each of the four demonstration groups, and the specifics of those demonstrations are summarized. A summary of the demonstrations of a novel liquid-free stimulation process which was performed in four groups of ''Candidate Wells'' situated in Crockett Co., TX; San Juan Co., NM; Phillips Co., MT; and Blaine Co., MT. The stimulation process which employs CO{sub 2} as the working fluid and the production responses were compared with those from wells treated with conventional stimulation technologies, primarily N{sub 2} foam, excepting those in Blaine Co., MT where the reservoir pressure is too low to clean up spent stimulation liquids. A total of 19 liquid-free CO{sub 2}/sand stimulations were performed in 16 wells and the production improvements were generally uneconomic.

Gas sensor  

DOE Patents [OSTI]

A gas sensor is described which incorporates a sensor stack comprising a first film layer of a ferromagnetic material, a spacer layer, and a second film layer of the ferromagnetic material. The first film layer is fabricated so that it exhibits a dependence of its magnetic anisotropy direction on the presence of a gas, That is, the orientation of the easy axis of magnetization will flip from out-of-plane to in-plane when the gas to be detected is present in sufficient concentration. By monitoring the change in resistance of the sensor stack when the orientation of the first layer's magnetization changes, and correlating that change with temperature one can determine both the identity and relative concentration of the detected gas. In one embodiment the stack sensor comprises a top ferromagnetic layer two mono layers thick of cobalt deposited upon a spacer layer of ruthenium, which in turn has a second layer of cobalt disposed on its other side, this second cobalt layer in contact with a programmable heater chip.

Determination of the Forms of Nitrogen Released in Coal Tar During Rapid Devolatilization. Semi-annual report, May 1-October 31, 1997  

SciTech Connect (OSTI)

The primary objective of this work is to determine the forms of nitrogen in coal that lead to nitrogen release during devolatilization. Experiments are to be performed in two existing laminar flow reactors available at Brigham Young University, which are both capable of temperatures (up to 2000 K), particle heating rates (104 to 105 K/s), and residence times (up to 500 ms) relevant to conditions commonly encountered in industrial pulverized coal combustors. The forms of nitrogen in coal, char, and tar samples are analyzed using state-of-the-art techniques, including nuclear magnetic resonance (NMR), X-Ray photoelectron spectroscopy (XPS), and high resolution nitrogen-specific chromatography. These sophisticated analysis techniques are being performed in collaboration with other researchers at BYU, the University of Utah, and industrial organizations. Coals have been obtained as a function of rank, including eight coals from the University of Utah that are to be used in pilot scale tests in support of the DOE Coal-2000 HIPPS (High Performance Power Systems) and LEBS (Low- Emission Boiler Systems) programs. Anticipated results from the proposed research are (a) nitrogen release parameters during devolatilization for specific coals pertinent to the HIPPS and LEBS projects, (b) better fundamental understanding of the chemistry of nitrogen release, and (c) a nitrogen release submodel based on fundamental chemistry that may be more widely applicable than existing empirical relationships.

Mortality and cancer experience of Quebec aluminum reduction plant workers. Part I: The reduction plants and coal tar pitch volatile (CTPV) exposure assessment  

SciTech Connect (OSTI)

This paper presents the exposure assessment and job-exposure matrix (JEM) used to estimate coal tar pitch volatile (CTPV) exposure for a study of mortality and cancer incidence in aluminum smelter workers in Quebec, Canada. Historical CTPV exposure was assessed by estimating benzene-soluble material (BSM) and benzo(a)pyrene (B(a)P) levels for combinations of job and time period. Estimates were derived by using several procedures including averaging measurement data, a deterministic mathematical model using process-related correction factors, and expert-based extrapolation. The JEM comprised 28,910 jobs, covering 7 facilities from 1916 to 1999. Estimated exposures ranged from 0.01 {mu} g/m{sup 3} to 68.08 {mu} g/m{sup 3} (B(a)P) and 0.01 mg/m{sup 3} to 3.64 mg/m{sup 3} (BSW) and were lowest before 1940 and after 1980. This methodology constitutes an improvement compared with methods used for previous studies of the Quebec cohort.

SOLVING THE SHUGART QUEEN SAND PENASCO UNIT DECLINING PRODUCTION PROBLEM  

SciTech Connect (OSTI)

The Penasco Shugart Queen Sand Unit located in sections 8, 9, 16 & 17, T18S, 31E Eddy County New Mexico is operated by MNA Enterprises Ltd. Co. Hobbs, NM. The first well in the Unit was drilled in 1939 and since that time the Unit produced 535,000 bbl of oil on primary recovery and 375,000 bbl of oil during secondary recovery operations that commenced in 1973. The Unit secondary to primary ratio is 0.7, but other Queen waterfloods in the area had considerably larger S/P ratios. On June 25 1999 MNA was awarded a grant under the Department of Energy's ''Technology Development with Independents'' program. The grant was used to fund a reservoir study to determine if additional waterflood reserves could be developed. A total of 14 well bores that penetrate the Queen at 3150 ft are within the Unit boundaries. Eleven of these wells produced oil during the past 60 years. Production records were pieced together from various sources including the very early state production records. One very early well had a resistivity log, but nine of the wells had no logs, and four wells had gamma ray-neutron count-rate perforating logs. Fortunately, recent offset deep drilling in the area provided a source of modern logs through the Queen. The logs from these wells were used to analyze the four old gamma ray-neutron logs within the Unit. Additionally the offset well log database was sufficient to construct maps through the unit based on geostatistical interpolation methods. The maps were used to define the input parameters required to simulate the primary and secondary producing history. The history-matched simulator was then used to evaluate four production scenarios. The best scenario produces 51,000 bbl of additional oil over a 10-year period. If the injection rate is held to 300 BWPD the oil rate declines to a constant 15 BOPD after the first year. The projections are reasonable when viewed in the context of the historical performance ({approx}30 BOPD with a {approx}600 BWPD injection rate during 1980-1990). If an additional source of water is developed, increasing the injection rate to 600 BWPD will double the oil-producing rate. During the log evaluation work the presence of a possibly productive Penrose reservoir about 200 ft below the Queen was investigated. The Penrose zone exists throughout the Unit, but appears to be less permeable than the Queen. The maps suggest that either well 16D or 16C are suitable candidates for testing the Penrose zone.

Holocene stratigraphy of the Alabama inner continental shelf: Influence of shelf sand ridges on determining lithofacies architecture  

SciTech Connect (OSTI)

Surface and subsurface distribution of lithofacies from Holocene sediments of the AL inner continental shelf was determined from a series of 59 vibracores and associated surface sediment grab sediments. Five Holocene lithofacies composed of 12 discrete microfacies were delineated based on grain size, color, sedimentary structures, shell content, and fabric of samples. These lithofacies include: (1) Graded Shelly Sand Lithofacies; (2) Clean Sand Lithofacies; (3) Dirty Sand Lithofacies; (4) Biogenic Sediment Lithofacies; and (5) Muddy Sediment Lithofacies. These represent four major depositional environments: The Shelf Sand Sheet Environment (lithofacies 1 and 2); the Sand Ridge Environment (lithofacies 1, 2, and 3); the Bay/Lagoon Environment (lithofacies 3, 4 and 5); and the Muddy Shelf Environment (lithofacies 5). East of the Main Pass of Mobile Bay, the seafloor is composed of a clean Shelf Sand Sheet with oblique shelf sand ridges; Clean Sand and Graded Shelly Sand are the dominant surface sediment types. Coarse shell beds that grade up to quartz sand units (total thickness 0.1 to 3+m) interpreted as tempestites comprise most of the upper portion of the ridges. West of the Pass, the muddier lithofacies (3 and 5) dominate surface samples. Microfacies at depth represent the early Holocene transgressive systems tract; these include the Muddy Shelf Depositional Environment and the filled estuaries and bays of the flooded Pleistocene fluvial valleys represented by the Bay/Lagoon Depositional Environment. The AL inner shelf provides an excellent model of the variability of sedimentation mode in time and space during deposition of a transgressive systems tract. Development of the palimpsest sand sheet/ridge complex progressed on the eastern shelf due to shut off of sediment influx, westward longshore currents, and episodic incidence of major hurricanes. On the western shelf a patchy distribution of muddier sediments developed from input of floodwaters from Mobile Bay.

High Energy Gas Fracturing Test  

SciTech Connect (OSTI)

The Rocky Mountain Oilfield Testing Center (RMOTC) has recently completed two tests of a high-energy gas fracturing system being developed by Western Technologies of Crossville, Tennessee. The tests involved the use of two active wells located at the Naval Petroleum Reserve No. 3 (NPR-3), thirty-five miles north of Casper, Wyoming (See Figure 1). During the testing process the delivery and operational system was enhanced by RMOTC, Western Technologies, and commercial wireline subcontractors. RMOTC has assisted an industrial client in developing their technology for high energy gas fracturing to a commercial level. The modifications and improvements implemented during the technology testing process are instrumental in all field testing efforts at RMOTC. The importance of well selection can also be critical in demonstrating the success of the technology. To date, significant increases in well productivity have been clearly proven in well 63-TPX-10. Gross fluid production was initially raised by a factor of three. Final production rates increased by a factor of six with the use of a larger submersible pump. Well productivity (bbls of fluid per foot of drawdown) increased by a factor of 15 to 20. The above results assume that no mechanical damage has occurred to the casing or cast iron bridge plug which could allow well production from the Tensleep ''B'' sand. In the case of well 61-A-3, a six-fold increase in total fluid production was seen. Unfortunately, the increase is clouded by the water injection into the well that was necessary to have a positive fluid head on the propellant tool. No significant increase in oil production was seen. The tools which were retrieved from both 63-TPX-10 and 61-A-3 indicated a large amount of energy, similar to high gram perforating, had been expended downhole upon the formation face.

On-site profiling and speciation of polycyclic aromatic hydrocarbons at manufactured gas plant sites by a high temperature transfer line, membrane inlet probe coupled to a photoionization detector and gas chromatography/mass spectrometer  

SciTech Connect (OSTI)

A new high temperature transfer line, membrane inlet probe (HTTL-MIP) coupled to a photoionization detector (PID) and gas chromatograph/mass spectrometer (GC/MS) was used to rapidly profile and speciate polycyclic aromatic hydrocarbons (PAH) in the subsurface. PID signals were in agreement with GC/MS results. Correlation coefficients of 0.92 and 0.99 were obtained for discrete and composite samples collected from the same exact location. Continuous probe advancement with PID detection found coal tar, a dense nonaqueous phase liquid, in soil channels and saturated media. When samples were collected conventionally, split, solvent extracted, and analyzed in the field and confirmation laboratory, GC/MS measurement precision and accuracy were indistinguishable; despite the fact the field laboratory produced data five times faster than the laboratory using standard EPA methods. No false positive/negatives were found. Based on these findings, increased confidence in site conceptual models should be obtained, since PID response indicated total PAH presence/absence in 'real-time', while GC/MS provided information as to which PAH was present and at what concentration. Incorporation of this tool into a dynamic workplan will provide more data at less cost enabling environmental scientists, engineers, and regulators to better understand coal tar migration and its impact on human health and the environment. 24 refs., 3 figs., 4 tabs.

Voidage and pressure profile characteristics of sand-iron ore-coal-FCC single-particle systems in the riser of a pilot plant circulating fluidized bed  

SciTech Connect (OSTI)

Hydrodynamic behaviors of single system of particles were investigated in a circulating fluidized bed (CFB) unit. Particles belonging to Geldart groups A and B like sand of various sizes (90, 300, 417, 522, 599, and 622 mu m), FCC catalyst (120 mu m), iron ore (166 and 140 {mu} m), and coal (335 and 168 {mu} m) were used to study the hydrodynamic characteristics. Superficial air velocity used in the present study ranged between 2.01 and 4.681 m/s and corresponding mass fluxes were 12.5-50 kg/(m{sup 2} s). A CFB needs the creation of some special hydrodynamic conditions, namely a certain combination of superficial gas velocity, solids circulation rate, particle diameter, density of particle, etc. which can give rise to a state wherein the solid particles are subjected to an upward velocity greater than the terminal or free fall velocity of the majority of the individual particles. The hydrodynamics of the bed was investigated in depth and theoretical analysis is presented to support the findings. Based on gas-solid momentum balance in the riser, a distinction between apparent and real voidage has been made. The effects of acceleration and friction on the real voidage have been estimated. Results indicated a 0.995 voidage for higher superficial gas velocity of 4.681. m/s.

Cocurrent gas - liquid flow at high rates in small particle beds  

SciTech Connect (OSTI)

Gas liquid cocurrent flow at high pressure drop often occurs near the well bore and in grabel filled perforations during production of oil and geothermal energy. Available studies have, however, emphasized large particles and low pressure drops. Here, results for air-water flows to high fluxes in beds of small glass spheres and in 0.44 mm sand, show the influence of particle size, and flow composition and rate, on pressure drop enhancement and flow regime extent.

The performance of the small-angle diffractometer, SAND at IPNS.  

SciTech Connect (OSTI)

The time-of-flight small-angle diffractometer SAND has been serving the scientific user community since 1996. One notable feature of SAND is its capability to measure the scattered intensity in a wide Q (4{pi}sin{theta}/{lambda}, where 2{theta} is the scattering angle and {lambda} is the wavelength of the neutrons) range of 0.0035 to 0.5 {angstrom}{sup {minus}1} in a single measurement. The optical alignment system makes it easy to set up the instrument and the sample. The cryogenically cooled MgO filter reduces the fast neutrons over two orders of magnitude, while still transmitting over 70% of the cold neutrons. A drum chopper running at 15 Hz suppresses the delayed neutron background. SAND has a variety of ancillary equipment to control the sample environment. In this paper we describe the features of the SAND instrument, compare its data on a few standard samples with those measured at well established centers in the world, and display two scientific examples which take advantage of measuring data in a wide Q-range in a single measurement. With a new set of tight collimators the Q{sub min} can be lowered to 0.002 {angstrom}{sup {minus}1} and the presently installed high-angle bank of detectors will extend the Q{sub max} to 2 {angstrom}{sup {minus}1}.
