Groundwater flow near the Shoal Site, Sand Springs Range, Nevada: Impact of density-driven flow  

SciTech Connect (OSTI)

The nature of flow from a highland recharge area in a mountain range in north-central Nevada to discharge areas on either side of the range is evaluated to refine a conceptual model of contaminant transport from an underground nuclear test conducted beneath the range. The test, known as the Shoal event, was conducted in 1963 in granitic rocks of the Sand Springs Range. Sparse hydraulic head measurements from the early 1960s suggest flow from the shot location to the east to Fairview Valley, while hydrochemistry supports flow to salt pans in Fourmile Flat to the west. Chemical and isotopic data collected from water samples and during well-logging arc best explained by a reflux brine system on the west side of the Sand Springs Range, rather than a typical local flow system where all flow occurs from recharge areas in the highlands to a central discharge area in a playa. Instead, dense saline water from the playa is apparently being driven toward the range by density contrasts. The data collected between the range and Fourmile Flat suggest the groundwater is a mixture of younger, fresher recharge water with older brine. Chemical contrasts between groundwater in the east and west valleys reflect the absence of re-flux water in Fairview Valley because the regional discharge area is distant and thus there is no accumulation of salts. The refluxing hydraulic system probably developed after the end of the last pluvial period and differences between the location of the groundwater divide based on hydraulic and chemical indicators could reflect movement of the divide as the groundwater system adjusts to the new reflux condition.

Nonparaxial Mathieu and Weber accelerating beams  

E-Print Network [OSTI]

We demonstrate both theoretically and experimentally nonparaxial Mathieu and Weber accelerating beams, generalizing the concept of previously found accelerating beams. We show that such beams bend into large angles along circular, elliptical or parabolic trajectories but still retain nondiffracting and self-healing capabilities. The circular nonparaxial accelerating beams can be considered as a special case of the Mathieu accelerating beams, while an Airy beam is only a special case of the Weber beams at the paraxial limit. Not only generalized nonparaxial accelerating beams open up many possibilities of beam engineering for applications, but the fundamental concept developed here can be applied to other linear wave systems in nature, ranging from electromagnetic and elastic waves to matter waves.

Radiological survey and evaluation of the fallout area from the Trinity test: Chupadera Mesa and White Sands Missile Range, New Mexico  

SciTech Connect (OSTI)

Current radiological conditions were evaluated for the site of the first nuclear weapons test, the Trinity test, and the associated fallout zone. The test, located on White Sands Missile Range, was conducted as part of the research with nuclear materials for the World War II Manhattan Engineer District atomic bomb project. Some residual radioactivity attributable to the test was found in the soils of Ground Zero on White Sands Missile Range and the areas that received fallout from the test. The study considered relevant information including historical records, environmental data extending back to the 1940s, and new data acquired by field sampling and measurements. Potential exposures to radiation were evaluated for current land uses. Maximum estimated doses on Chupadera Mesa and other uncontrolled areas are less than 3% of the DOE Radiation Protection Standards (RPSs). Radiation exposures during visits to the US Army-controlled Ground Zero area are less than 1 mrem per annual visit or less than 0.2% of the RPS for a member of the public. Detailed data and interpretations are provided in appendixes. 14 figs., 45 tabs.

Submilisecond acoustic pulses: effective pitch and Weber-Fechner law in discrimination of duration times  

E-Print Network [OSTI]

The enclosed tests demonstrate that an effective pitch can be attributed to acoustic signals shorter then tenths of milliseconds. A power-law dependence of this pitch on the signal's duration time is found for subjects tested with Gaussian pulses. The discrimination threshold for the pulse duration time reported on the basis of the effective pitch increases proportionally to the duration time itself, i.e. it follows the Weber-Fechner law. A model based on the "Helmholtz's harp" idea, i.e. a series of damped resonators tuned in the audible range of frequencies, reveals the mechanism of producing a maximum in the filtered spectrum of the pulse. This corroborates the power law in the dependence of the position of the maximum on the duration time of the pulse. The model indicates a possibility of designing a manmade device dedicated to determination of the durations so short that they are inaccessible by direct measurements.

Phase behavior of methane hydrate in silica sand  

Science Journals Connector (OSTI)

Abstract Two kinds of silica sand powder with different particle size were used to investigate the phase behavior of methane hydrate bearing sediment. In coarse-grained silica sand, the measured temperature and pressure range was (281.1 to 284.2) K and (5.9 to 7.8) MPa, respectively. In fine-grained silica sand, the measured temperature and pressure range was (281.5 to 289.5) K and (7.3 to 16.0) MPa, respectively. The results show that the effect of coarse-grained silica sand on methane hydrate phase equilibrium can be ignored; however, the effect of fine-grained silica sand on methane hydrate phase equilibrium is significant, which is attributed to the depression of water activity caused by the hydrophilicity and negatively charged characteristic of silica particle as well as the pore capillary pressure. Besides, the analysis of experimental results using the Gibbs–Thomson equation shows that methane hydrate phase equilibrium is related to the pore size distribution of silica sand. Consequently, for the correct application of phase equilibrium data of hydrate bearing sediment, the geological condition and engineering requirement should be taken into consideration in gas production, resource evaluation, etc.

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.

The freezing tendency towards 4-coordinated amorphous network causes increase in heat capacity of supercooled Stillinger-Weber silicon  

E-Print Network [OSTI]

The supercooled liquid silicon, modeled by Stillinger-Weber potential, shows anomalous increase in heat capacity $C_p$, with a maximum $C_p$ value close to 1060 K at zero pressure. We study equilibration and relaxation of the supercooled SW Si, in the temperature range of 1060 K--1070 K at zero pressure. We find that as the relaxation of the metastable supercooled liquid phase initiates, a straight line region (SLR) is formed in cumulative potential energy distributions. The configurational temperature corresponding to the SLR is close to 1060 K, which was earlier identified as the freezing temperature of 4-coordinated amorphous network. The SLR is found to be tangential to the distribution of the metastable liquid phase and thus influences the broadness of the distribution. As the bath temperature is reduced from 1070 K to 1060 K, the effective temperature approaches the bath temperature which results in broadening of the metastable phase distribution. This, in turn, causes an increase in overall fluctuations of potential energy and hence an increase of heat capacity. We also find that during initial stages of relaxation, 4-coordinated atoms form 6-membered rings with a chair--like structure and other structural units that indicate crystallization. Simultaneously a strong correlation is established between the number of chair-shaped 6-membered rings and the number of 4-coordinated atoms in the system. This shows that all properties related to 4-coordinated particles are highly correlated as the SLR is formed in potential energy distributions and this can be interpreted as a consequence of `freezing' of amorphous network formed by 4-coordinated particles.

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.

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.

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.

Aerothermoballistics of pyrophoric metal shrapnel in high speed, high Weber number flows. [From non-nuclear detonation of nuclear weapon  

SciTech Connect (OSTI)

A numerical simulation is presented on the aerothermoballistic behavior of pyrophoric metal shrapnel ejected at supersonic speeds from a non-nuclear detonation of a nuclear weapon. The model predicts the aerodynamic and chemical heat transfer rates and the particle thermal responses including the time and position of melt initiation. Due to the high Weber number environment, the melting particle undergoes liquid layer stripping. The theoretical model, which is incorporated in the PLUTO computer code, predicts the liquid mass loss rate, characteristic liquid droplet diameter, temperature rise across the liquid film, and the coupled particle trajectory.

Heterotrophic denitrification of aquaculture effluent using fluidized sand biofilters  

Science Journals Connector (OSTI)

Abstract The ability to consistently and cost-effectively reduce nitrate-nitrogen loads in effluent from recirculating aquaculture systems would enhance the industry's environmental stewardship and allow improved facility proximity to large markets in sensitive watersheds. Heterotrophic denitrification technologies specifically employing organic carbon found in aquaculture system waste offer a unique synergy for treatment of land-based, closed-containment production outflows. For space-efficient fluidized sand biofilters to be used as such denitrification reactors, system parameters (e.g., influent dissolved oxygen and carbon to nitrogen ratios, C:N) must be evaluated to most effectively use an endogenous carbon source. The objectives of this work were to quantify nitrate removal under a range of C:Ns and to explore the biofilter bacterial community using three replicated fluidized sand biofilters (height 3.9 m, diameter 0.31 m; fluidized sand volume plus biofilm volume of 0.206 m3) operated at a hydraulic retention time of 15 min and a hydraulic loading rate of 188 L/min m2 at The Conservation Fund Freshwater Institute in Shepherdstown, West Virginia, USA. Nitrate reduction was consistently observed during the biofilter study period (26.9 ± 0.9% removal efficiency; 402 ± 14 g NO3-N/(m3 biofilter d)) although nitrite-N and total ammonium nitrogen concentrations slightly increased (11 and 13% increases, respectively). Nitrate removal efficiency was correlated with carbonaceous oxygen demand to nitrate ratios (R2 > 0.70). Nitrate removal rates during the study period were moderately negatively correlated with influent dissolved oxygen concentration indicating it may be possible the biofilter hydraulic retention time was too short to provide optimized nitrate removal. It is reasonable to assume that the efficiency of nitrate removal across the fluidized sand biofilters could be substantially increased, as long as organic carbon was not limiting, by increasing biofilter bed depths (to 6–10 m), and thus hydraulic retention time. These findings provide a low-cost yet effective technology to remove nitrate-nitrogen from effluent waters of land-based closed-containment aquaculture systems.

Deep-water bottom-current reworked sands: Their recognition and reservoir potential, northern Gulf of Mexico  

SciTech Connect (OSTI)

Some Pliocene and Pleistocene reservoir sands in intraslope basins of the northern Gulf of Mexico exhibit features that are interpreted to be indicative of reworking by deep-water (bathyal) bottom currents (contour currents). These fine sands have previously been interpreted as turbidites associated with levee overbanks and lobes of submarine fan complexes; however, sedimentological features characteristic of turbidites are rare in these laminated sands. Common features observed are (1) numerous (up to 75 layers/m) thin (<2 cm) sand layers, (2) sharp upper contacts, (3) inverse grading, (4) current ripples, (5) lenticular bedding, (6) flaser bedding, (7) bidirectional cross-lamination, and (8) sigmoidal bed forms with mud drapes (i.e., mud offshoots). These features, dominated by traction structures, can be explained by reworking of overbank turbidite sands by deep-bottom currents. In the present Gulf of Mexico, the surface Loop Current is considered to be a major cause of deep circulation. The authors propose that similar bottom currents and perhaps minor deep tidal currents existed during Pliocene and Pleistocene times. The entire sediment package may be thick and continuous, but individual sand layers within the package are thin and discontinuous. Porosity values of these sands range from 27 to 40%, and permeability ranges from 100 to 2,000 md at 200 psi. In seismic profiles or seismic facies maps, it is difficult to distinguish the reworked sands from turbidites. Therefore, geologic models based on core and process sedimentology are the key to a better understanding of these often misinterpreted complex reservoir facies.

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.

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.

Macrodispersion in sand-shale sequences  

SciTech Connect (OSTI)

Macrodispersion in sand-shale sequences is investigated by a series of numerical tracer tests. Hydraulic conductivity is modeled as a binary, spatially correlated random function. Realizations of the random conductivity field are simulated on a nodal grid discretizing the heterogeneous formation. Corresponding realizations of the random velocity field are obtained by solving the equation for saturated steady state flow. Particle tracking, with flux-weighted tracer injection and detection, is used to generate experimental residence time distributions (RTDs). Moments of the RTD are used to characterize longitudinal tracer spreading. Results show that macrodispersive transport in sand-shale sequences cannot be represented by a Fickian model. RTDs display a bimodal structural caused by the fast arrival of particles traveling along preferential sandstone and shale. The relative importance of channeling and tortuous flow transport mechanisms is determined by sand-shale conductivity contrast, shale volume fraction, and conductivity spatial correlation structure. Channeling is promoted by high conductivity contrasts, low shale fractions, and flow parallel to bedding in anisotropic media. Low contrasts, high shale fractions, and flow perpendicular to bedding act to break up channels and to enhance tracer spreading.

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.

Sphere impact and penetration into wet sand  

Science Journals Connector (OSTI)

We present experimental results for the penetration of a solid sphere when released onto wet sand. We show, by measuring the final penetration depth, that the cohesion induced by the water can result in either a deeper or shallower penetration for a given release height compared to dry granular material. Thus the presence of water can either lubricate or stiffen the granular material. By assuming the shear rate is proportional to the impact velocity and using the depth-averaged stopping force in calculating the shear stress, we derive effective viscosities for the wet granular materials.

Induction log analysis of thinly laminated sand/shale formation  

SciTech Connect (OSTI)

The author examines induction log responses to a thinly laminated sand/shale sequence in a deviated borehole for arbitrary deviation (or dip) angle and sand/shale composition. He found that the induction log responses in a thinly laminated sand/shale sequence are the same as they would be if the tool is placed in a homogeneous but anisotropic formation with the horizontal and vertical conductivities given respectively by the parallel and the series conductivities of the sequence. Conversely, a thinly laminated sand/shale sequence can be identified as an anisotropic formation by induction logs. He discusses three methods to identify an anisotropic formation using induction-type logs alone.

Direct numerical simulations of aeolian sand ripples  

E-Print Network [OSTI]

Aeolian sand beds exhibit regular patterns of ripples resulting from the interaction between topography and sediment transport. Their characteristics have been so far related to reptation transport caused by the impacts on the ground of grains entrained by the wind into saltation. By means of direct numerical simulations of grains interacting with a wind flow, we show that the instability turns out to be driven by resonant grain trajectories, whose length is close to a ripple wavelength and whose splash leads to a mass displacement towards the ripple crests. The pattern selection results from a compromise between this destabilizing mechanism and a diffusive downslope transport which stabilizes small wavelengths. The initial wavelength is set by the ratio of the sediment flux and the erosion/deposition rate, a ratio which increases linearly with the wind velocity. We show that this scaling law, in agreement with experiments, originates from an interfacial layer separating the saltation zone from the static sand bed, where momentum transfers are dominated by mid-air collisions. Finally, we provide quantitative support for the use the propagation of these ripples as a proxy for remote measurements of sediment transport.

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...

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.

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.

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.

The effect of methane hydrate morphology and water saturation on seismic wave attenuation in sand under shallow sub-seafloor conditions  

Science Journals Connector (OSTI)

Abstract A better understanding of seismic wave attenuation in hydrate-bearing sediments is needed for the improved geophysical quantification of seafloor methane hydrates, important for climate change, geohazard and economic resource assessment. Hence, we conducted a series of small strain (hydrate-bearing sands under excess-water seafloor conditions. The results show a complex dependence of P- and S-wave attenuation on hydrate saturation and morphology. P- and S-wave attenuation in excess-water hydrate-bearing sand is much higher than in excess-gas hydrate-bearing sand and increases with hydrate saturation between 0 and 0.44 (the experimental range). Theoretical modelling suggests that load-bearing hydrate is an important cause of heightened attenuation for both P- and S-waves in gas and water saturated sands, while pore-filling hydrate also contributes significantly to P-wave attenuation in water saturated sands. A squirt flow attenuation mechanism, related to microporous hydrate and low aspect ratio pores at the interface between sand grains and hydrate, is thought to be responsible for the heightened levels of attenuation in hydrate-bearing sands at low hydrate saturations (<0.44).

Direct Production of Silicones From Sand  

SciTech Connect (OSTI)

Silicon, in the form of silica and silicates, is the second most abundant element in the earth's crust. However the synthesis of silicones (scheme 1) and almost all organosilicon chemistry is only accessible through elemental silicon. Silicon dioxide (sand or quartz) is converted to chemical-grade elemental silicon in an energy intensive reduction process, a result of the exceptional thermodynamic stability of silica. Then, the silicon is reacted with methyl chloride to give a mixture of methylchlorosilanes catalyzed by cooper containing a variety of tract metals such as tin, zinc etc. The so-called direct process was first discovered at GE in 1940. The methylchlorosilanes are distilled to purify and separate the major reaction components, the most important of which is dimethyldichlorosilane. Polymerization of dimethyldichlorosilane by controlled hydrolysis results in the formation of silicone polymers. Worldwide, the silicones industry produces about 1.3 billion pounds of the basic silicon polymer, polydimethylsiloxane.

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.

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.

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.

Electrostatic cleaning system for removal of sand from solar panels  

Science Journals Connector (OSTI)

Abstract An improved cleaning system has been developed that uses electrostatic force to remove sand from the surface of solar panels. A single-phase high voltage is applied to parallel wire electrodes embedded in the cover glass plate of a solar panel. It has been demonstrated that more than 90% of the adhering sand is repelled from the surface of the slightly inclined panel after the cleaning operation. The performance of the system was further improved by improving the electrode configuration and introducing natural wind on the surface of the panel, even when the deposition of sand on the panel is extremely high. The power consumption of this system is virtually zero. This technology is expected to increase the effective efficiency of mega solar power plants constructed in deserts at low latitudes.

Frisco City sand: New Jurassic reservoir in southwest Alabama  

SciTech Connect (OSTI)

The first commercial production of hydrocarbons from the Jurassic Haynesville Formation in southwestern Alabama was from the Frisco City field. The field currently produces 57.8{degree} API gravity oil on 160-ac well spacing from a depth of approximately 12,000 ft. Perforations are in the Frisco City sand interval, in the lower part of the Haynesville Formation. Average porosity is 15% and average permeability is 45 md. Currently, the field has two producing wells with cumulative production of over 138,876 bbl of oil and 213,144 mcf of gas. The hydrocarbon trap in the Frisco City field is a combination structural-stratigraphic trap. The Frisco City sand reservoir is located on a faulted anticline. The stratigraphic trap is produced by a permeability barrier near the crest of the structure and termination against a basement high. The lower part of the Haynesville Formation in this area is comprised of (in ascending order) the Buckner Anhydrite Member, the Frisco City sand, and interbedded shale and anhydrite. Sandstones of the Frisco City sand interval were deposited in a shallow marine setting and have a sheetlike morphology. The sandstones are poorly to moderately sorted, angular to rounded arkose, and contain angular to rounded pebbles. The sandstones are interbedded with thin, sandy, mudstones that contribute, along with patchy carbonate and anhydrite cement, to considerable reservoir heterogeneity. Porosity is predominantly primary intergranular with a small amount of framework grain dissolution and decementation.

Stratigraphy of Upper Miocene Potter sands, Midway-Sunset field, Kern County, California  

SciTech Connect (OSTI)

Upper Miocene Potter sands in the northern part of the Midway-Sunset field were analyzed extensively using detailed electric-log correlations. Structural and stratigraphic cross sections and subsurface mapping demonstrate variations across four general areas in T31S, R22E, referred to as west (parts of Secs. 16, 17, 21), north (parts of Secs. 15, 16), east (part of sec. 14), and south (within Sec. 27). Potter sands deposited in the west area represent the oldest strata of the Potter sequence because they unconformably overlie older silts, diatomaceous shales, and isolated sand channels believed to be part of the Antelope Shale Member. These sands are interpreted to represent massive debris flow/grain flows deposited in a proximal channel-trough system that carried sediments from west to east, toward the low point of the Midway syncline. In the north area, Potter sands change abruptly from massive sands in the eastern part of Sec. 16 to thinner sand channels with more correlative and continuous silt interbeds in Sec. 15. The massive sands are stratigraphically equivalent, if not slightly younger than, sands in the west. However, at the base, these sands depositionally onlap onto the southwest flank of the globe anticline. The Potter sand channel packages thin in Sec. 15, which represents lateral facies changes within the system as the sand to silt ratios become lower and the silts become more continuous. Potter sands in the east area are the uppermost and youngest strata encountered in the study area. Although massive sand channel packages are common, they show better lateral continuity and exhibit lower sand to silt ratios than the north sequences. In the south area, Potter sands are interbedded with continuous silt units that can be mapped over much of the section.

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.

Bonding Strength by Methane Hydrate Formed among Sand Particles  

Science Journals Connector (OSTI)

The mechanical properties of methane hydrate?bearing sand were investigated by low temperature and high confining pressure triaxial testing apparatus in the present study. The specimens were prepared by infiltrating the methane gas into partially saturated sand specimen under the given temperature and stress condition which is compatible with the phase equilibrium condition for the stability of methane hydrate. The tests were firstly performed to investigate the effect of temperature on the shear behaviour of the specimen. Then the effect of backpressure was investigated. The strength of methane hydrate bearing sand increased as the temperature decreased and the back pressure increased. The bonding strength due to methane hydrate was dependent on methane hydrate saturation temperature and back pressure but independent of effective stress. Dissociation tests of methane hydrate were also performed by applying the temperature to the specimen at the various initial stress conditions. The marked development of shear and volumetric strains were observed due to dissociation of the methane hydrate in the specimen corresponding to the initial stress conditions.

National Metal Casting Research Institute final report. Volume 1, Sand reclamation  

SciTech Connect (OSTI)

A mobile thermal foundry sand reclamation unit was designed and constructed. This unit consisted of thermal and mechanical sand reclamation equipment installed on the bed of a 50 foot low-boy trailer. It was transported to a number of Midwest foundries for on-site demonstration of the sand reclamation process. This allowed participating foundries to have their own refuse sand (10-100 tons) processed and then reused in production for evaluation. The purpose for building the unit was to demonstrate to foundries through ``hands on`` experience that refuse sands can be reclaimed and successfully reused particularly in regard to product quality. Most of the participating foundries indicated a high level of satisfaction with the reclaimed sand. Laboratory testing of samples of the used sand, before and after processing by the demonstration unit, verified the usability of the reclaimed sand. One of the foundries participating was a brass foundry, the sand from this foundry contained lead and is classified as a hazardous material. After reclamation the sand was no longer hazardous and could also be reused in the foundry.

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.

Solvent extraction of oil shale or tar sands  

SciTech Connect (OSTI)

Oil shales or tar sands are extracted under non-thermally destructive conditions with a solvent liquid containing a compound having the general formula: R(N)-M(=O)(-R1)-N(-R2)-R3 where M is a carbon, sulfur or phosphorus atom, R/sup 2/ and R/sup 3/ are each a hydrogen atom or a lowe alkyl group, R and R/sup 1/ are each a lower alkyl group, another -N(-R2)-R3 group, a monocyclic arom group, or R/sup 1/ can be another -N(-R3)-M(=O)(-R1)-R(N) group or R/sup 1/ and R/sup 2/ together can represent the atoms necessary to close a heterocyclic ring, and n=1 where M=phosphorus and is otherwise 0, to substantially remove the non-fixed carbon content of the oil shale or tar sands, leaving a solid residue of fixed carbon, ash minerals, and non-extractable matter.

Baseline for beached marine debris on Sand Island, Midway Atoll  

Science Journals Connector (OSTI)

Baseline measurements were made of the amount and weight of beached marine debris on Sand Island, Midway Atoll, June 2008–July 2010. On 23 surveys, 32,696 total debris objects (identifiable items and pieces) were collected; total weight was 740.4 kg. Seventy-two percent of the total was pieces; 91% of the pieces were made of plastic materials. Pieces were composed primarily of polyethylene and polypropylene. Identifiable items were 28% of the total; 88% of the identifiable items were in the fishing/aquaculture/shipping-related and beverage/household products-related categories. Identifiable items were lowest during April–August, while pieces were at their lowest during June–August. Sites facing the North Pacific Gyre received the most debris and proportionately more pieces. More debris tended to be found on Sand Island when the Subtropical Convergence Zone was closer to the Atoll. This information can be used for potential mitigation and to understand the impacts of large-scale events such as the 2011 Japanese tsunami.

Superfund Record of Decision (EPA Region 8): Ogden Defense Depot, Operable Unit 1, Weber County, UT. (Second remedial action), June 1992  

SciTech Connect (OSTI)

Since 1941, the 1,100-acre Ogden Defense Depot (DDOU) site, located in Ogden, Weber County, Utah, has been a key installation in the Department of Defense supply system. Operable Unit 1, which is located in the southwest part of the DDOU, is composed of the backfill material in the Plain City Canal, Burial Site 1, and Burial Site 3-B. Burial Site 1 was reported to have been used for the disposal of riot control agent (chloroacetophenone) and white smoke (hexachloroethane) containers in the 1940's. In the early 1960's, Burial Site 3-B was reportedly the burying ground for over 1,000 arctic-style rubber boots. The ROD addresses a final remedy for OU1 that will reduce the principal threats posed by contaminated soil and shallow ground water at the site. The primary contaminants of concern affecting the soil, debris, and ground water are VOCs, including TCE; other organics, including dioxins and pesticides; and metals, including arsenic and lead.

A receiver imposes another periodic modulation on the received optical signal, the modulated signal being detected by an array of detectors of the integrating type. Range to the target determined by measuring the phase shift of the intensity modulation on the received optical beam relative to a reference. The receiver comprises a photoemitter for converting the reflected, periodically modulated, return beam to an accordingly modulated electron stream. The electron stream is modulated by a local demodulation signal source and subsequently converted back to a photon stream by a detector. A charge coupled device (CCD) array then averages and samples the photon stream to provide an electrical signal in accordance with the photon stream.

A case study of multipole acoustic logging in heavy oil sand reservoirs  

Science Journals Connector (OSTI)

The multipole acoustic logging tool (MPAL) was tested in the heavy oil sand reservoirs of Canada. Compared with near shales the P-wave slowness of heavy oil sands does not change obviously with the value of about 125?s/ft; the dipole shear slowness decreases significantly to 275?s/ft. The heavy oil sands have a Vp/Vs value of less than 2.4. The slowness and amplitude of dipole shear wave are good lithology discriminators that have great differences between heavy oil sands and shales. The heavy oil sand reservoirs are anisotropic. The crossover phenomenon in the fast and slow dipole shear wave dispersion curves indicates that the anisotropy is induced by unbalanced horizontal stress in the region.

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.

Preliminary relative permeability estimates of methanehydrate-bearing sand  

SciTech Connect (OSTI)

The relative permeability to fluids in hydrate-bearing sediments is an important parameter for predicting natural gas production from gas hydrate reservoirs. We estimated the relative permeability parameters (van Genuchten alpha and m) in a hydrate-bearing sand by means of inverse modeling, which involved matching water saturation predictions with observations from a controlled waterflood experiment. We used x-ray computed tomography (CT) scanning to determine both the porosity and the hydrate and aqueous phase saturation distributions in the samples. X-ray CT images showed that hydrate and aqueous phase saturations are non-uniform, and that water flow focuses in regions of lower hydrate saturation. The relative permeability parameters were estimated at two locations in each sample. Differences between the estimated parameter sets at the two locations were attributed to heterogeneity in the hydrate saturation. Better estimates of the relative permeability parameters require further refinement of the experimental design, and better description of heterogeneity in the numerical inversions.

Methane hydrate formation and dissociation in a partially saturated sand  

SciTech Connect (OSTI)

To predict the behavior of hydrate-bearing sediments and the economic extractability of natural gas from reservoirs containing gas hydrates, we need reservoir simulators that properly represent the processes that occur, as well as accurate parameters. Several codes are available that represent some or all of the expected processes, and values for some parameters are available. Where values are unavailable, modelers have used estimation techniques to help with their predictions. Although some of these techniques are well respected, measurements are needed in many cases to verify the parameters. We have performed a series of experiments in a partially water saturated silica sand sample. The series included methane hydrate formation, and dissociation by both thermal stimulation and depressurization. The sample was 7.6 cm in diameter and 25 cm in length. In addition to measuring the system pressure and temperatures at four locations in the sample, we measured local density within the sample using x-ray computed tomography. Our goals in performing the experiment were to gather information for estimating thermal properties of the medium and to examine nonequilibrium processes.

Hydrotreating the native bitumen from the Whiterocks tar sand deposit  

SciTech Connect (OSTI)

The bitumen from the Whiterocks oil sand deposit in the Uinta Basin of eastern Utah was hydrotreated in a fixed-bed reactor to determine the extent of upgrading as a function of process operating variables. The process variables investigated included reactor pressure (11.2--16.7 MPa); reactor temperature (641--712 K) and liquid hourly space velocity (0.19--0.77 h{sup {minus}1}). The hydrogen/oil ratio, 890 m{sup 3} m{sup {minus}3} was fixed in all experiments. A sulphided Ni-Mo on alumina hydrodenitrogenation catalyst was used in these studies. The deactivation of the catalyst, 0.2 {degree}C/day, was monitored by thedecline in the API gravity of the total liquid product with time on-stream at a standard set of conditions. The effect of temperature, WHSV, and pressure on denitrogenation, desulphurization, and metals removalwere studied and apparent kinetic parameters determined. The effect of process variables on residue conversion and Conradson carbon residue reduction were also investigated.

Methane Hydrate Formation and Dissocation in a Partially Saturated Sand--Measurements and Observations  

SciTech Connect (OSTI)

We performed a sequence of tests on a partially water-saturated sand sample contained in an x-ray transparent aluminum pressure vessel that is conducive to x-ray computed tomography (CT) observation. These tests were performed to gather data for estimation of thermal properties of the sand/water/gas system and the sand/hydrate/water/gas systems, as well as data to evaluate the kinetic nature of hydrate dissociation. The tests included mild thermal perturbations for the estimation of the thermal properties of the sand/water/gas system, hydrate formation, thermal perturbations with hydrate in the stability zone, hydrate dissociation through thermal stimulation, additional hydrate formation, and hydrate dissociation through depressurization with thermal stimulation. Density changes throughout the sample were observed as a result of hydrate formation and dissociation, and these processes induced capillary pressure changes that altered local water saturation.

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. Additional information about the PEIS can be found at http://ostseis.anl.gov.

Electrical anisotropy of gas hydrate-bearing sand reservoirs in the Gulf of Mexico  

Science Journals Connector (OSTI)

We present new results and interpretations of the electrical anisotropy and reservoir architecture in gas hydrate-bearing sands using logging data collected during the Gulf of Mexico Gas Hydrate Joint Industry Project Leg II. We focus specifically on sand reservoirs in Hole Alaminos Canyon 21 A (AC21-A), Hole Green Canyon 955 H (GC955-H) and Hole Walker Ridge 313 H (WR313-H). Using a new logging-while-drilling directional resistivity tool and a one-dimensional inversion developed by Schlumberger, we resolve the resistivity of the current flowing parallel to the bedding, R? and the resistivity of the current flowing perpendicular to the bedding, R?. We find the sand reservoir in Hole AC21-A to be relatively isotropic, with R? and R? values close to 2 ? m. In contrast, the gas hydrate-bearing sand reservoirs in Holes GC955-H and WR313-H are highly anisotropic. In these reservoirs, R? is between 2 and 30 ? m, and R? is generally an order of magnitude higher. Using Schlumberger’s WebMI models, we were able to replicate multiple resistivity measurements and determine the formation resistivity the gas hydrate-bearing sand reservoir in Hole WR313-H. The results showed that gas hydrate saturations within a single reservoir unit are highly variable. For example, the sand units in Hole WR313-H contain thin layers (on the order of 10–100 cm) with varying gas hydrate saturations between 15 and 95%. Our combined modeling results clearly indicate that the gas hydrate-bearing sand reservoirs in Holes GC955-H and WR313-H are highly anisotropic due to varying saturations of gas hydrate forming in thin layers within larger sand units.

Velocity anisotropy should be taken into account when analyzing the amplitude variation with offset (AVO) response of gas sands encased in shales. The anisotropic effects on the AVO of gas sands in transversely isotropic (TI) media are reviewed. Reflection coefficients in TI media are computed using a planewave formula based on ray theory. The authors present results of modeling special cases of exploration interest having positive reflectivity, near-zero reflectivity, and negative reflectivity. The AVO reflectivity in anisotropic media can be decomposed into two parts; one for isotropy and the other for anisotropy. Zero-offset reflectivity and Poisson's ratio contract are the most significant parameters for the isotropic component while the [delta] difference ([Delta][delta]) between shale and gas sand is the most important factor for the anisotropic component. For typical values of TI anisotropy in shale (positive [delta] and [var epsilon]), both [delta] difference ([Delta][delta]) and [var epsilon] difference ([Delta][var epsilon]) amplify AVO effects. For small angles on incidence, [Delta][delta] plays an important role in AVO while [Delta][var epsilon] dominates for large angles of incidence. For typical values of [delta] and [var epsilon], the effects of anisotropy in shale are: (1) a more rapid increase in AVO for Class 3 and Class 2 gas sands, (2) a more rapid decrease in AVO for Class 1 gas sands, and (3) a shift in the offset of polarity reversal for some Class 1 and Class 2 gas sands.

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.

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.

Inorganic Carbon Turnover caused by Digestion of Carbonate Sands and Metabolic Activity of Holothurians  

SciTech Connect (OSTI)

Recent measurements have shown that holothurians (sea cucumbers) play an important role in the cycling of CaCO3 in tropical coral reef systems through ingestion and processing of carbonate sediment. In this study inorganic additional aspects of carbon turnover were determined in laboratory incubations of Holothuria atra, H. leucospilota and Stichopus herrmanni from One Tree Reef, Great Barrier Reef. The pH values of the gut lumen ranged from 6.1 to 6.7 in animals with empty digestive tracts as opposed to 7.0 to 7.6 when digestive tracts were filled with sediment. Empty gut volume estimates for H. atra and S. herrmanni were 36 ± 4 mL and 151 ± 14 mL, respectively. Based on these measurements it is estimated that these species process 19 ± 2kg and 80 ± 7kg CaCO3 sand yr-1 per individual, respectively. The annual dissolution rates of H. atra and S. herrmanni of 6.5±1.9g and 9.6±1.4g, respectively, suggest that 0.05±0.02% and 0.1±0.02% of the CaCO3 processed through their gut annually is dissolved. During the incubations the CaCO3 dissolution was 0.07±0.01%, 0.04±0.01% and 0.21±0.05% of the fecal casts for H. atra, H. leucospilota and S. herrmanni, respectively. The CaCO3 saturation state for both aragonite and calcite minerals during laboratory incubations decreased markedly due to a greater increase in dissolved inorganic carbon (DIC) relative to total alkalinity (AT) as a result of respiration by the animals. Our results support the hypothesis that deposit feeders such as sea cucumbers play an important ecological role in the coral reef CaCO3 cycle.

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.

Influence of depositional sand quality and diagenesis on porosity and permeability: Examples from Brent Group reservoirs, northern North Sea  

SciTech Connect (OSTI)

Multivariate statistical analysis was applied to examine correlations between reservoir quality and petrology in two data sets from the Middle Jurassic Brent Group. One of the data sets is from relatively shallow depth and has been little affected by chemical diagenesis (Statfjord Nord and Ost Fields; 2.3--2.6 km below the sea floor), while the second data set is from a more deeply buried reservoir having an advanced degree of diagenesis (Huldra Field; 3.6--3.9 km). Much of the total variation in porosity and permeability within each data set (0.02 mD to > 7 D in both sets) can be accounted for by laboratory measurements of parameters mainly related to depositional sand quality, including shaliness (represented by bulk-rock alumina/silica ratio), early carbonate cement, feldspar content, and grain size. Despite major differences in the proportions of different sedimentary facies in the two data sets, they have similar ranges of depositional sand quality and therefore probably had similar reservoir quality early in their burial history. Deeper burial diagenesis at Huldra Field has shifted the average of both porosity and permeability to lower values and produced a bimodal permeability distribution, apparently reflecting preferential preservation of permeability in the cleaner sandstones. On the basis of these examples, the author outlines an approach for unmixing the diagenetic and lithologic components of variation in regional compilations of sandstone porosity-permeability data. The procedure and its consequences are illustrated using a regional compilation of core data from the Brent Group of the northern North Sea.

Assessment of sand drift potential along the Nile Valley and Delta using climatic and satellite data  

Science Journals Connector (OSTI)

Abstract Sand encroachment is a significant environmental hazard prevailing across the western fringes of the Nile Valley and Delta due to the occurrence of many dune fields in the adjacent Western Desert. Climatic data acquired from five meteorological stations were used to assess drifting sand and dune activity along this heavily populated and cultivated region. Dune forms and rates of dune advance were extracted from remotely sensed images. Results showed that wind environment and topography are the significant factors for the distribution of aeolian deposits. Wind energy and sand drift are maximum in the Middle Egypt and minimum west of the Nile Delta. Transverse (barchan) dunes are the dominant throughout the study area. Nevertheless, longitudinal (linear) dunes are observed west of the Nile Delta. The southern one-third of the study area is bordered by an elevated plateau from the west that hinders significant dune clusters from reaching the Nile Valley. Development projects in the contiguous fringes west of the Nile Valley would respond negatively to sand encroachment.

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.

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.

Process sedimentology and reservoir quality of deep-marine bottom-current reworked sands (sandy contourites): An example from the Gulf of Mexico  

SciTech Connect (OSTI)

Deep-marine bottom-current reworked sands (sandy contourites) have been recognized in hydrocarbon-bearing sands of the Gulf of Mexico. A distinctive attribute of these sands is their traction bed forms, which occur in discrete units. Common sedimentary features of traction currents include cross-bedding, current ripples, horizontal lamination, sharp upper contacts, and inverse size grading. These sands also exhibit internal erosional surfaces and mud offshoots, indicating oscillating current energy conditions. THe Pliocene-Pleistocene sequence cored in the Ewing Bank Block 826 field in the Gulf of Mexico provides an example of sand distribution and reservoir quality of deep-marine bottom-current reworked sands. Presumably, the Loop Current, a strong wind-driven surface current in the Gulf of Mexico, impinged on the sea bottom, as it does today, and resulted in bottom-current reworked sands. A depositional model based on the integration of well (core and log) and three-dimensional seismic data suggests that the reworked sediment package may be thick and continuous, but individual sand layers within the package may be thin and discontinuous. This unconventional model, which depicts the distribution of bottom-current reworked sands in interchannel slope areas as a distinctly different facies from channel-levee facies, has the potential for general application to other slope plays outside the study area. In the Ewing Bank Block 826 field, the type I (L-1) reservoir with 80% sand exhibits higher permeability values (100-1800 md) than the type 2 (N-1) reservoir with 26% sand (50-800 md). The increased permeability in the type I sand has been attributed to high sand content, vigorous reworking, and microfractures. The clean, porous, and well-sorted type 1 sands with good communication between sand layers have produced at higher rates and recovery efficiencies than the type 2 sands with numerous interbedded mud layers. 50 refs., 22 figs., 1 tab.

X-ray computed-tomography observations of water flow through anisotropic methane hydrate-bearing sand  

SciTech Connect (OSTI)

We used X-ray computed tomography (CT) to image and quantify the effect of a heterogeneous sand grain-size distribution on the formation and dissociation of methane hydrate, as well as the effect on water flow through the heterogeneous hydrate-bearing sand. A 28 cm long sand column was packed with several segments having vertical and horizontal layers with sands of different grain-size distributions. During the hydrate formation, water redistribution occurred. Observations of water flow through the hydrate-bearing sands showed that water was imbibed more readily into the fine sand, and that higher hydrate saturation increased water imbibition in the coarse sand due to increased capillary strength. Hydrate dissociation induced by depressurization resulted in different flow patterns with the different grain sizes and hydrate saturations, but the relationships between dissociation rates and the grain sizes could not be identified using the CT images. The formation, presence, and dissociation of hydrate in the pore space dramatically impact water saturation and flow in the system.

Effect of dilution and contaminants on strength and hydraulic conductivity of sand grouted with colloidal silica gel  

SciTech Connect (OSTI)

Colloidal silica (CS) is a low-viscosity liquid that can be made to gel by addition of brine. This property allows it to be injected into, or mixed with, soil, so that after gelling the colloidal silica blocks the pore space in the soil and forms a barrier to the flow of contaminated groundwater or non-aqueous liquids (NAPLs). Gelled-in-place CS was first studied for the petroleum industry and later for protecting groundwater quality. Noll investigated the use of colloidal silica diluted so that its solids content was reduced from 30% (a typical nominal value for material as delivered) to values as low as 5%. The more dilute colloids could still be made to gel, although more slowly, and the resulting gel was weaker. Because the proposed application of colloidal silica grout involves emplacing it in the subsurface by permeation, jet grouting, or soil mixing where its role as a barrier will be to resist flow of contaminants, the effects of these contaminants on the properties of the grouted soil is also of interest. This work comprised four tasks. In Task 1, samples of grouted sand were prepared with a range of CS dilutions, for measurement of hydraulic conductivity and unconfined-compressive strength. In Task 2, these properties were measured on samples of grouted sand that incorporated 5% volumetric saturation of NAPLs. In Task 3, samples, prepared without any contaminants, were immersed in contaminant liquids and tested after 30 and 90 days. Task 4 was added because NAPL contamination in the samples of Tasks 2 and 3 impelled modifications in the test methods, and comparison of the results of Task 2 and Task 1 suggested that these modifications had introduced errors. In Task 4, samples were tested both ways, to confirm that in Tasks 2 and 3 strength was underestimated and hydraulic conductivity was overestimated. Despite the existence of these known systematic errors, the inclusion of control samples in Tasks 2 and 3 permits conclusions to be drawn from these data.

Live Fire Range Environmental Assessment  

SciTech Connect (OSTI)

The Central Training Academy (CTA) is a DOE Headquarters Organization located in Albuquerque, New Mexico, with the mission to effectively and efficiently educate and train personnel involved in the protection of vital national security interests of DOE. The CTA Live Fire Range (LFR), where most of the firearms and tactical training occurs, is a complex separate from the main campus. The purpose of the proposed action is to expand the LFR to allow more options of implementing required training. The Department of Energy has prepared this Environmental Assessment (EA) for the proposed construction and operation of an expanded Live Fire Range Facility at the Central Training Academy in Albuquerque, New Mexico. Based on the analysis in the EA, DOE has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an environmental impact statement is not required and DOE is issuing this Finding of No Significant Impact (FONSI).

Sand transverse dune aerodynamics: 3D Coherent Flow Structures from a computational study  

E-Print Network [OSTI]

The engineering interest about dune fields is dictated by the their interaction with a number of human infrastructures in arid environments. The aerodynamic behaviour of sand dunes in atmospheric boundary layer belongs to the class of bluff bodies. Because of their simple geometry and their frequent occurrence in desert area, transverse sand dunes are usually adopted in literature as a benchmark to investigate dune aerodynamics by means of both computational or experimental approach, usually in nominally 2D setups. The writers suspect the flow in the wake is characterised by 3D features and affected by wind tunnel setup - e.g. blockage effect, duct side wall boundary layer, incoming velocity profile - when experimental studies are carried out. The present study aims at evaluating the 3D flow features of an idealised transverse dune under different setup conditions by means of computational simulations and to compare the obtained results with experimental measurements.

Methane Hydrate Formation and Dissociation in a PartiallySaturated Core-Scale Sand Sample  

SciTech Connect (OSTI)

We performed a sequence of tests on a partiallywater-saturated sand sample contained in an x-ray transparent aluminumpressure vessel that is conducive to x-ray computed tomography (CT)observation. These tests were performed to gather data for estimation ofthermal properties of the sand/water/gas system and thesand/hydrate/water/gas systems, as well as data to evaluate the kineticnature of hydrate dissociation. The tests included mild thermalperturbations for the estimation of the thermal properties of thesand/water/gas system, hydrate formation, thermal perturbations withhydrate in the stability zone, hydrate dissociation through thermalstimulation, additional hydrate formation, and hydrate dissociationthrough depressurization with thermal stimulation. Density changesthroughout the sample were observed as a result of hydrate formation anddissociation, and these processes induced capillary pressure changes thataltered local water saturation.

Reservoir characterization of thinly laminated heterolithic facies within shallow-marine sand bodies  

SciTech Connect (OSTI)

Shallow marine sandstones typically form high quality reservoirs but they can contain a significant proportion of extremely heterogeneous facies. Particularly significant are heterolithic (mixed interlaminated sand-mud) deposits which are common in estuarine/incised valley-fill reservoirs and other tidally-influenced depositional environments. The complex mm/cm-scale interfingering of sands and clays in these reservoirs is below the resolution of most logging tools, which poses major problems for the petrophysical evaluation, quantitative reservoir modelling and reservoir performance prediction. This study outlines an integrated geological/petrophysical framework for the reservoir characterization of heterolithic facies from the Jurassic of the North Sea Basin which utilizes well logs, cores, minipermeameter and analog outcrop data. The calibration of wireline logs (GR, LDT/CNL, EPT and dipmeter) with cores helps in establishing the relationship between the architecture of sand-shale laminations and their wireline log response/electrofacies. The routine sampling procedure for porosity/permeability measurement from cores will not accurately determine the average reservoir properties for these heterolithic intervals. The selection of measurement points is of vital importance for determining average reservoir properties. The minipermeameter measurements are especially useful for these thin bedded reservoirs and serve as a useful guide for reservoir zonation and evaluation of petrophysical properties from wireline logs. The incorporation of analog outcrop data helps further in establishing vertical and lateral communication relationships at field scale.

Western Gas Sands Subprogram. Status report, October-November-December 1982  

SciTech Connect (OSTI)

The progress during October, November and December 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 Western Gas Sands Subprogram (WGSS) Quarterly Status Report. During the quarter, major changes were made in the management of the subprogram. Personnel in the Division of Petroleum Projects Management at the Morgantown Energy Technology Center (METC) assumed the role of management for the Western Gas Sands Subprogram that had been performed by the Bartlesville Energy Technology Center (BETC). BETC continued in-house research on the fluid and proppant problems of fracture conductivity, and management of the Multi-Well Experiment (MWX). Owing to economic constraints, all efforts at the Sandia National Laboratory that were not directly related to the performance of MWX were terminated. The projects at the Lawrence Livermore National Laboratory and the Los Alamos National Laboratory were reduced by approximately 50 percent. The efforts at the USGS were reduced by 70 percent. Significant progress was made in the MWX project. Both the Upper and Lower Cozzette zones were production tested. Interference tests run on the Upper Cozzette showed much higher in situ permeability than core and log analysis indicated. This higher permeability has been attributed to the natural fractures. The site was closed for the winter on December 22 and the test trailer moved to CER Corporation, Las Vegas, for maintenance and upgrading. 40 figures, 16 tables.

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)

Integration of reclamation and tailings management in oil sands surface mine planning  

Science Journals Connector (OSTI)

Abstract The processing of oil sands generates large volumes of slurry, known as tailings, that is impounded in tailings ponds. Oil sands operators are committed to develop reclamation plans to ensure that the mine site is restored to a natural or economically usable landscape. Since most of the material that is needed for capping of the tailings pond is produced in mining operation, it is reasonable to include material requirement for reclamation as part of mine planning. In this paper, an integrated long-term mine planning model is proposed that includes tailings capacity and reclamation material requirements. A mixed integer linear programming (MILP) model is developed to test the performance of the proposed model. The MILP model is coded in Matlab®. It is verified by carrying out a case study on an actual oil sands dataset, and has resulted in an integer solution within a 2% gap to the optimality. The resulted production schedule meets the capacity constraint of the tailings facility and guarantees the production of the required reclamation material.

Biodiesel production from used cooking oil and sea sand as heterogeneous catalyst  

Science Journals Connector (OSTI)

Abstract The aim of this study was to analyze the catalytic performance of sea sand as a nonconventional catalyst in the transesterification reaction of used cooking oil and refined oil with methanol. The sea sand was utilized as a source of calcium oxide. The main characteristic of this sea sand is the high content of CaCO3 which was transformed into CaO by calcination. The catalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption/desorption (BET) and by Hammett method (basicity determination). The produced biodiesel has 95.4% (polar + non polar methyl esters), 96.6% and 97.5% methyl esters content when employing used cooking oil, safflower oil and soybean oil, respectively. The obtained biodiesel at these conditions (atmospheric pressure, reaction temperature of 60 °C, 12:1 M ratio of methanol:oil and catalyst amount of 7.5%) met key parameters (viscosity: 4.2–5.0 mm2/s and acid value: 0.05–0.011 mg KOH/g) of the European norm EN-14214 (viscosity: 3.5–5.0 mm2/g and acid value: max. 0.50 mg KOH/g).

Stratigraphy, coal occurrence, and depositional history of the Paleocene Fort Union Formation, Sand Wash basin, northwestern Colorado  

SciTech Connect (OSTI)

The Fort Union Formation in the Sand Wash basin is divided into the massive Cretaceous and Tertiary (K/T) sandstone unit, lower coal-bearing unit, gray-green mudstone unit, basin sandy unit, and upper shaly unit. Lithofacies and coal-occurrence maps of the stratigraphic units indicate that sandstone bodies and coal beds occur along south-north oriented, intermontane fluvial systems. Net-sandstone-thickness trends of the massive K/T sandstone unit reveal laterally extensive channel-fill sandstones formed in north-flowing fluvial systems. The massive K/T sandstone unit's dominant source was in the Sawatch Range. Sandstones within the lower coal-bearing unit consist of similar north-flowing fluvial systems, but they are laterally discontinuous and have several tectonically active source areas, including the Uinta and Sierra Madre-Park uplifts, and Sawatch Range. Coal-occurrence maps of the lower coal-bearing unit indicate that maximum coal-bed thicknesses are greatest along the south-north-oriented fluvial axes. Coal beds thin and split to the east and west, confirming a direct relation between the position of thick, fluvial-sandstone bodies, which form a stable platform for peat accumulation, and the location of the thick coal beds. Above the lower coal-bearing unit, the gray-green mudstone unit forms north-trending belts centered R91W and R100W. The gray-green mudstone thins to the north and into the basin center and probably is lacustrine in origin, reflecting tectonic quiescence and cessation of coarse clastic sedimentation. The basin sandy unit is best developed in the central parts of the basin, where its fluvial depositional axis is oriented south-north. The upper shaly unit directly overlies the basin sandy unit and includes a thin Cherokee coal zone. The upper shaly unit has variable thicknesses due to erosion at the base of the Wasatch Formation and lateral facies changes.

A nuclear DNA based phylogeny of endemic sand dune ants of the genus Mycetophylax (Emery, 1913): How morphology is reflected in molecular data  

Science Journals Connector (OSTI)

Abstract Molecular methods have substantially advanced our knowledge about ant systematics in the past few years. Here, we infer the molecular phylogeny of sand dune ants of the genus Mycetophylax, Emery 1913 (Formicidae: Myrmicinae: Attini) using 730 base pairs of DNA sequences of the two nuclear genes longwave rhodopsin and wingless. Our analyses indicate that Mycetophylax is monophyletic, as suggested by its morphological characters. M. morschi, previously considered a species of Cyphomyrmex due to a scrobe-like impressed area on the head, forms a well-supported cluster with the two other species of Mycetophylax, M. conformis and M. simplex. Our analysis yields the first comprehensive phylogeny of Mycetophylax based on molecular data and includes specimens from localities within a wide distributional range as well as all species belonging to the genus following the recent taxonomic revision.

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.

Quantitative Methods for Reservoir Characterization and Improved Recovery: Application to Heavy Oil Sands  

SciTech Connect (OSTI)

This project involved application of advanced analytical property-distribution methods conditioned to continuous outcrop control for improved reservoir characterization and simulation. The investigation was performed in collaboration with Chevron Production Company U.S.A. as an industrial partner, and incorporates data from the Temblor Formation in Chevron's West Coalinga Field, California. Improved prediction of interwell reservoir heterogeneity was needed to increase productivity and to reduce recovery cost for California's heavy oil sands, which contained approximately 2.3 billion barrels of remaining reserves in the Temblor Formation and in other formations of the San Joaquin Valley.

Innovative logistics for the transportation of sand and gravel in Brazil  

Science Journals Connector (OSTI)

The transportation of sand and gravel, which are highly consumed in civil construction, is traditionally hauled on roads and highways. Currently, the growing demand in large metropolitan areas is met by an increasing road fleet, which delivers the aggregates from the origin to construction sites. This paper discusses alternative distribution means for aggregates in Sao Paulo, Brazil, focusing on the cost-reduction opportunities associated with the use of railway and waterway modals. The benefits identified in the research are not merely limited to greater competitiveness due to the reduction of costs in logistics, but also to reducing traffic jams.

Radar range measurements in the atmosphere.  

SciTech Connect (OSTI)

The earth's atmosphere affects the velocity of propagation of microwave signals. This imparts a range error to radar range measurements that assume the typical simplistic model for propagation velocity. This range error is a function of atmospheric constituents, such as water vapor, as well as the geometry of the radar data collection, notably altitude and range. Models are presented for calculating atmospheric effects on radar range measurements, and compared against more elaborate atmospheric models.

Flowsheet modifications for dissolution of sand, slag, and crucible residues in the F-canyon dissolvers  

SciTech Connect (OSTI)

An initial flowsheet for the dissolution of sand, slag, and crucible (SS{ampersand}C) was developed for the F- Canyon dissolvers as an alternative to dissolution in FB-Line. In that flowsheet, the sand fines were separated from the slag chunks and crucible fragments. Those two SS{ampersand}C streams were packaged separately in mild-steel cans for dissolution in the 6.4D dissolver. Nuclear safety constraints limited the dissolver charge to approximately 350 grams of plutonium in two of the three wells of the dissolver insert and required 0.23M (molar) boron as a soluble neutron poison in the 9.3M nitric acid/0.013M fluoride dissolver solution. During the first dissolution of SS{ampersand}C fines, it became apparent that a significant amount of the plutonium charged to the 6.4D dissolver did not dissolve in the time predicted by previous laboratory experiments. The extended dissolution time was attributed to fluoride complexation by boron. An extensive research and development (R{ampersand}D) program was initiated to investigate the dissolution chemistry and the physical configuration of the dissolver insert to understand what flowsheet modifications were needed to achieve a viable dissolution process.

Factors that affect the degradation of naphthenic acids in oil sands wastewater by indigenous microbial communities  

SciTech Connect (OSTI)

The acute toxicity of wastewater generated during the extraction of bitumen from oil sands is believed to be due to naphthenic acids (NAs). To determine the factors that affect the rate of degradation of representative NAs in microcosms containing wastewater and the acute toxicity of treated and untreated wastewater, the effects of temperature, dissolved oxygen concentration, and phosphate addition on the rate of {sup 14}CO{sub 2} release form two representative naphthenic acid substrates, (linear) U-{sup 14}C-palmitic acid (PA) and (bicyclic) decahydro-2-naphthoic acid-8-{sup 14}C (DHNA), were monitored. Tailings pond water (TPW) contained microorganisms well adapted to mineralizing both PA and DHNA:PA was degraded more quickly (10--15% in 4 weeks) compared to DHNA (2--4% in 8 weeks). On addition of phosphate, the rate of NA degradation increased up to twofold in the first 4 weeks, with a concurrent increase in the rate of oxygen consumption by oil sands TPW. The degradation rate then declined to levels equivalent to those measured in flasks without phosphate. The observed plateau was not due to phosphate limitation. Decreases in either the dissolved oxygen concentration or the temperature reduced the rate. Phosphate addition also significantly decreased the acute toxicity of TPW to fathead minnows. In contrast, Microtox{reg_sign} analyses showed no reduction in the toxicity of treated or untreated TPW after incubation for up to 8 weeks at 15 C.

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.

Perch population assessment in lakes reclaimed using oil-sands derived material  

SciTech Connect (OSTI)

The mining and extraction of petroleum products from oil-sands involves large areas of land and produces enormous volumes of tailings. One possible land reclamation option is to incorporate fine-tailings material into the bottoms of constructed lakes capped with natural surface water. The wet landscape method represents potential risk to aquatic biota-naphthenic acids and PAHs elute from pore water contained in the fine-tailings substrate. In spring 1995 yellow perch were stocked into a large-scale (5ha) experimental pond that consisted of fine-tailings capped with natural water as well as into two other reclaimed ponds that were constructed with oil-sands overburden material. Prior to stocking of perch, ponds had colonized with cyprinids, macrophytes and benthic invertebrates over a two year period. Perch were sampled in fall 1995 for age, condition factor, liver size, gonad size, fecundity, stomach contents, liver mixed-function oxygenase activity (MFO), bile PAH metabolites and plasma steroid hormones. When compared to the source lake, perch in the DP did not show reduced reproductive potential. Perch in all of the reclaimed ponds demonstrated exposure to organic compounds as indicated by marginally induced MFO activity and increased liver size. Exposure to naphthenates and PAHs in water as well as ecological environmental factors will be discussed.

This WGSP Quarterly Report summarizes the progress of government-sponsored projects aimed at recovering gas from low permeability gas sands in the Western United States during October, November and December 1981. CK GeoEnergy released the final report for Development of Techniques for Optimizing Selection and Completion of Western Gas Sands. For CER's Reservoir Simulation Model Development, primary emphasis during the quarter was placed on extending the previous work to include effects of massive hydraulic fractures intersecting multiple lenses. During the quarter, the University of Oklahoma completed the two-dimensional reservoir simulator for BETC. A simplified two-dimensional hydraulic fracturing model is being developed by LLL. A major activity this quarter at Los Alamos was redesigning the NMR receiver system, making it capable of being repackaged for downhole use. Sandia summarizes the analysis of five saturated rock samples that were measured for dielectric constant. The drilling, coring, logging and casing of MWX-1 was accomplished this quarter; quality of output, mainly core, core data and logs, has been good.

Methane hydrate formation and dissociation in a partially saturated core-scale sand sample  

SciTech Connect (OSTI)

We performed a series of experiments to provide data for validating numerical models of gas hydrate behavior in porous media. Methane hydrate was formed and dissociated under various conditions in a large X-ray transparent pressure vessel, while pressure and temperature were monitored. In addition, X-ray computed tomography (CT) was used to determine local density changes during the experiment. The goals of the experiments were to observe changes occurring due to hydrate formation and dissociation, and to collect data to evaluate the importance of hydrate dissociation kinetics in porous media. In the series of experiments, we performed thermal perturbations on the sand/water/gas system, formed methane hydrate, performed thermal perturbations on the sand/hydrate/water/gas system resulting in hydrate formation and dissociation, formed hydrate in the resulting partially dissociated system, and dissociated the hydrate by depressurization coupled with thermal stimulation. Our CT work shows significant water migration in addition to possible shifting of mineral grains in response to hydrate formation and dissociation. The extensive data including pressure, temperatures at multiple locations, and density from CT data is described.

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.

Evolution of seismic velocities in heavy oil sand reservoirs during thermal recovery process  

E-Print Network [OSTI]

In thermally enhanced recovery processes like cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD), continuous steam injection entails changes in pore fluid, pore pressure and temperature in the rock reservoir, that are most often unconsolidated or weakly consolidated sandstones. This in turn increases or decreases the effective stresses and changes the elastic properties of the rocks. Thermally enhanced recovery processes give rise to complex couplings. Numerical simulations have been carried out on a case study so as to provide an estimation of the evolution of pressure, temperature, pore fluid saturation, stress and strain in any zone located around the injector and producer wells. The approach of Ciz and Shapiro (2007) - an extension of the poroelastic theory of Biot-Gassmann applied to rock filled elastic material - has been used to model the velocity dispersion in the oil sand mass under different conditions of temperature and stress. A good agreement has been found between these pre...

Varying properties of in situ heat treatment of a tar sands formation based on assessed viscosities  

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.

Strength behavior of methane hydrate bearing sand in undrained triaxial testing  

Science Journals Connector (OSTI)

Gas hydrates represent a potential future energy source as well as a considerable geohazard. In order to assess both the benefits and risks that gas hydrate bearing sediments pose, fundamental information about their physical properties is required. In this study, the undrained shear strength of methane hydrate bearing sand was investigated. The experimental program required modifications to an existing triaxial apparatus and accurate determination of the hydrate saturation lead to the use of two methods for comparison of the saturation calculations. Strength results indicated that the presence of gas hydrate will increase the sediment's undrained shear strength and corresponding stiffness. The relative contribution of cohesion and friction angle was observed to be a function of the hydrate saturation, for this particular hydrate formation methodology.

Marine gas hydrates in thin sand layers that soak up microbial methane  

Science Journals Connector (OSTI)

At Site U1325 (IODP Exp. 311, Cascadia margin), gas hydrates occupy 20–60% of pore space in thin sand layers (hydrate. This is a common occurrence in gas hydrate-bearing marine sequences, and it has been related to the inhibition of hydrate formation in the small pores of fine-grained sediments. This paper applies a mass balance model to gas hydrate formation in a stack of alternating fine- and coarse-grained sediment layers. The only source of methane considered is in situ microbial conversion of a small amount of organic carbon (gas hydrates in the fine-grained layers. Methane generated in these layers is transported by diffusion into the coarse-grained layers where it forms concentrated gas hydrate deposits. The vertical distribution and amount of gas hydrate observed at Site U1325 can be explained by in situ microbial methane generation, and a deep methane source is not necessary.

Policy Analysis of Water Availability and Use Issues for Domestic Oil Shale and Oil Sands Development  

SciTech Connect (OSTI)

Oil shale and oil sands resources located within the intermountain west represent a vast, and as of yet, commercially untapped source of energy. Development will require water, and demand for scarce water resources stands at the front of a long list of barriers to commercialization. Water requirements and the consequences of commercial development will depend on the number, size, and location of facilities, as well as the technologies employed to develop these unconventional fuels. While the details remain unclear, the implication is not – unconventional fuel development will increase demand for water in an arid region where demand for water often exceeds supply. Water demands in excess of supplies have long been the norm in the west, and for more than a century water has been apportioned on a first-come, first-served basis. Unconventional fuel developers who have not already secured water rights stand at the back of a long line and will need to obtain water from willing water purveyors. However, uncertainty regarding the nature and extent of some senior water claims combine with indeterminate interstate river management to cast a cloud over water resource allocation and management. Quantitative and qualitative water requirements associated with Endangered Species protection also stand as barriers to significant water development, and complex water quality regulations will apply to unconventional fuel development. Legal and political decisions can give shape to an indeterminate landscape. Settlement of Northern Ute reserved rights claims would help clarify the worth of existing water rights and viability of alternative sources of supply. Interstate apportionment of the White River would go a long way towards resolving water availability in downstream Utah. And energy policy clarification will help determine the role oil shale and oil sands will play in our nation’s future.

Determining the ecological viability of constructed wetlands for the treatment of oil sands wastewater  

SciTech Connect (OSTI)

To determine the conditions for optimal degradation of naphthenic acids (C{sub n}H{sub 2n+z}O{sub 2}), the most toxic component of oil sands wastewater, the authors have monitored the mineralization of 2 representative naphthenic acids (NA), U-{sup 14}C-palmitic acid (linear, Z = 0) and 8-{sup 14}C-decahydro-2-naphthoic acid (bicyclic, Z = {minus}4) under varying conditions of temperature, phosphate and oxygen. The radiolabeled NA was added to biometer flasks containing wastewater {+-} amendments and evolved {sup 14}C-CO{sub 2} was trapped in a side arm and counted by LSC. The results indicate that low temperature (5 C) and anaerobiasis greatly inhibited NA degradation over the four week incubation period. Addition of phosphate (as buffered KP{sub i}) significantly increased {sup 14}C-CO{sub 2} production for both Z = 0 and Z = {minus}4 compounds; however, the subsequent high microbial growth rates also decreased PO{sub 2} which limited NA mineralization. Effluent toxicity was monitored at week 0 and week 4 using Microtox and fathead minnow tests. Although there was increased survival of fathead minnows in the phosphate-amended effluent, the IC{sub 20} values of the Microtox assay showed no improvement in either the phosphate-treated or untreated effluents. These results show that naphthenic acid analogues are readily degraded by indigenous microorganisms in oil sands wastewater and that phosphate addition accelerated the mineralization of these compounds if PO{sub 2} remained high.

Tonopah Test Range capabilities: technical manual  

SciTech Connect (OSTI)

This manual describes Tonopah Test Range (TTR), defines its testing capabilities, and outlines the steps necessary to schedule tests on the Range. Operated by Sandia National Laboratories, TTR is a major test facility for DOE-funded weapon programs. The Range presents an integrated system for ballistic test vehicle tracking and data acquisition. Multiple radars, optical trackers, telemetry stations, a central computer complex, and combined landline/RF communications systems assure full Range coverage for any type of test. Range operations are conducted by a department within Sandia's Field Engineering Directorate. While the overall Range functions as a complete system, it is operationally divided into the Test Measurements, Instrumentation Development, and Range Operations divisions. The primary function of TTR is to support DOE weapons test activities. Management, however, encourages other Government agencies and their contractors to schedule tests on the Range which can make effective use of its capabilities. Information concerning Range use by organizations outside of DOE is presented. Range instrumentation and support facilities are described in detail. This equipment represents the current state-of-the-art and reflects a continuing commitment by TTR management to field the most effective tracking and data acquisition system available.

Scale-dependent gas hydrate saturation estimates in sand reservoirs in the Ulleung Basin, East Sea of Korea  

Science Journals Connector (OSTI)

Through the use of 2-D and 3-D seismic data, several gas hydrate prospects were identified in the Ulleung Basin, East Sea of Korea and thirteen drill sites were established and logging-while-drilling (LWD) data were acquired from each site in 2010. Sites UBGH2–6 and UBGH2–10 were selected to test a series of high amplitude seismic reflections, possibly from sand reservoirs. LWD logs from the UBGH2–6 well indicate that there are three significant sand reservoirs with varying thickness. Two upper sand reservoirs are water saturated and the lower thinly bedded sand reservoir contains gas hydrate with an average saturation of 13%, as estimated from the P-wave velocity. The well logs at the UBGH2–6 well clearly demonstrated the effect of scale-dependency on gas hydrate saturation estimates. Gas hydrate saturations estimated from the high resolution LWD acquired ring resistivity (vertical resolution of about 5–8 cm) reaches about 90% with an average saturation of 28%, whereas gas hydrate saturations estimated from the low resolution A40L resistivity (vertical resolution of about 120 cm) reaches about 25% with an average saturation of 11%. However, in the UBGH2–10 well, gas hydrate occupies a 5-m thick sand reservoir near 135 mbsf with a maximum saturation of about 60%. In the UBGH2–10 well, the average and a maximum saturation estimated from various well logging tools are comparable, because the bed thickness is larger than the vertical resolution of the various logging tools. High resolution wireline log data further document the role of scale-dependency on gas hydrate calculations.

Reservoir description of a sand-rich submarine fan complex for a steamflood project: upper Miocene Potter sandstone, North Midway Sunset field, California  

SciTech Connect (OSTI)

Nearly 650 m of cores from the upper Miocene Potter sandstone in Mobil's Alberta/Shale property, North Midway Sunset field, California, were examined to determine depositional facies, sand-body geometry, and reservoir quality for a proposed steamflood project. The Potter represents a sand-rich submarine fan complex with braided-channel, meandering-channel, levee, and crevasse-splay facies. The braided-channel facies (gravel and coarse sand) is thick (up to 100 m), sheetlike (> 500 m wide), and highly permeable (10,000 + md). The meandering-channel facies (coarse to medium sand) is up to 20 m thick, over 400 m long, lenticular in geometry, and exhibits an upward decrease in permeability (e.g., 9000 to 500 md) related to grain size that fines upward. The levee facies (in bioturbated sand) is up to 21 m thick, shows variable geometry, and is generally low in permeability (100-1500 md). The crevasse splay (medium sand) is up to 12 m thick, sheetlike (> 300 m wide), and shows moderately high permeability (2000-8000 md). The braided-channel facies was a product of density-modified grain flows, and the remaining three facies were deposited by turbidity currents. Steam flooding of the Potter reservoir should perform extremely well because the entire reservoir is composed of relatively clean sand and the reservoir lacks both horizontal and vertical permeability barriers.

The available data on neutron scattering were analyzed to constrain a hypothetical new short-range interaction. We show that these constraints are several orders of magnitude better than those usually cited in the range between 1 pm and 5 nm. This distance range occupies an intermediate space between collider searches for strongly coupled heavy bosons and searches for new weak macroscopic forces. We emphasise the reliability of the neutron constraints in so far as they provide several independent strategies. We have identified the most promising way to improve them.

Active dendrites enhance neuronal dynamic range  

E-Print Network [OSTI]

Since the first experimental evidences of active conductances in dendrites, most neurons have been shown to exhibit dendritic excitability through the expression of a variety of voltage-gated ion channels. However, despite experimental and theoretical efforts undertaken in the last decades, the role of this excitability for some kind of dendritic computation has remained elusive. Here we show that, owing to very general properties of excitable media, the average output of a model of active dendritic trees is a highly non-linear function of their afferent rate, attaining extremely large dynamic ranges (above 50 dB). Moreover, the model yields double-sigmoid response functions as experimentally observed in retinal ganglion cells. We claim that enhancement of dynamic range is the primary functional role of active dendritic conductances. We predict that neurons with larger dendritic trees should have larger dynamic range and that blocking of active conductances should lead to a decrease of dynamic range.

Range Separated Brueckner Coupled Cluster Doubles Theory  

E-Print Network [OSTI]

We introduce a range-separation approximation to coupled cluster doubles (CCD) theory that successfully overcomes limitations of regular CCD when applied to the uniform electron gas. We combine the short-range ladder channel with the long-range ring channel in the presence of a Bruckner renormalized one-body interaction and obtain ground-state energies with an accuracy of 0.001 a.u./electron across a wide range of density regimes. Our scheme is particularly useful in the low-density and strongly-correlated regimes, where regular CCD has serious drawbacks. Moreover, we cure the infamous overcorrelation of approaches based on ring diagrams (i.e. the particle-hole random phase approximation). Our energies are further shown to have appropriate basis set and thermodynamic limit convergence, and overall this scheme promises energetic properties for realistic periodic and extended systems which existing methods do not possess.

Assessment of fish health effects resulting from exposure to oil sands wastewater  

SciTech Connect (OSTI)

The objective of this study was to determine if oil sands wastewater had an effect on the general health and condition of hatchery raised rainbow trout (200 to 400 g). Effects were assessed based on a battery of physiological and biochemical indices and the physical condition of the fish. The trout were exposed to tailings water in the field and in a flow through system under laboratory conditions. The field tests were conducted in 1992 and 1993 in experimental ponds at Syncrude which contained fine tails covered with surface water, fine tails covered with tailings water, and a surface water control pond. The laboratory treatments included Mildred Lake tailings water, dyke drainage water, fractionated tailings pond water (acid fraction containing naphthenic acids), sodium naphthenate, recycle water from Suncor`s tailings pond, and a laboratory control. All body condition factors and blood parameters were normal in the field and laboratory exposed fish and there were no apparent differences between the fish exposed to the tailings water and controls.

We performed a series of experiments to provide data forvalidating numerical models of gas hydrate behavior in porous media.Methane hydrate was formed and dissociated under various conditions in alarge X-ray transparent pressure vessel, while pressure and temperaturewere monitored. In addition, X-ray computed tomography (CT) was used todetermine local density changes during the experiment. The goals of theexperiments were to observe changes occurring due to hydrate formationand dissociation, and to collect data to evaluate the importance ofhydrate dissociation kinetics in porous media. In the series ofexperiments, we performed thermal perturbations on the sand/water/gassystem, formed methane hydrate, performed thermal perturbations on thesand/hydrate/water/gas system resulting in hydrate formation anddissociation, formed hydrate in the resulting partially dissociatedsystem, and dissociated the hydrate by depressurization coupled withthermal stimulation. Our CT work shows significant water migration inaddition to possible shifting of mineral grains in response to hydrateformation and dissociation. The extensive data including pressure,temperatures at multiple locations, and density from CT data isdescribed.

Techno-economic assessment of hydrogen production from underground coal gasification (UCG) in Western Canada with carbon capture and sequestration (CCS) for upgrading bitumen from oil sands  

Science Journals Connector (OSTI)

Abstract This paper examines the techno-economic viability of hydrogen production from underground coal gasification (UCG) in Western Canada, for the servicing of the oil sands bitumen upgrading industry. Hydrogen production for bitumen upgrading is predominantly achieved via steam methane reforming (SMR); which involves significant greenhouse gas (GHG) emissions along with considerable feedstock (natural gas) cost volatility. UCG is a formidable candidate for cost-competitive environmentally sustainable hydrogen production; given its negligible feedstock cost, the enormity of deep coal reserves in Western Canada and the favourable CO2 sequestration characteristics of potential UCG sites in the Western Canadian sedimentary basin (WCSB). Techno-economic models were developed for UCG and SMR with and without CCS, to estimate the cost of hydrogen production including delivery to a bitumen upgrader. In this paper, at base case conditions, a 5% internal rate of return (IRR) differential between UCG and SMR was considered so as to account for the increased investment risk associated with UCG. The cost of UCG hydrogen production without CCS is estimated to be $1.78/kg of H2. With CCS, this increases to range of $2.11–$2.70/kg of H2, depending on the distance of the site for CO2 sequestration from the UCG plant. The SMR hydrogen production cost without CCS is estimated to be $1.73/kg of H2. In similar fashion to UCG, this rises to a range of $2.14 to $2.41/kg of H2 with the consideration of CCS. Lastly, for hydrogen production without CCS, UCG has a superior cost competitiveness in comparison to SMR for an IRR differential less than 4.6%. This competitive threshold rises to 5.4% for hydrogen production with CCS.

Tonopah Test Range Air Monitoring: CY2013 Meteorological, Radiological, and Airborne Particulate Observations  

SciTech Connect (OSTI)

In 1963, the U.S. Department of Energy (DOE) (formerly the Atomic Energy Commission [AEC]), implemented Operation Roller Coaster on the Tonopah Test Range (TTR) and an adjacent area of the Nevada Test and Training Range (NTTR) (formerly the Nellis Air Force Range). This test resulted in radionuclide-contaminated soils at Clean Slate I, II, and III. This report documents observations made during on-going monitoring of radiological, meteorological, and dust conditions at stations installed adjacent to Clean Slate I and Clean Slate III and at the TTR Range Operations Control center. The primary objective of the monitoring effort is to determine if winds blowing across the Clean Slate sites are transporting particles of radionuclide-contaminated soils beyond both the physical and administrative boundaries of the sites. Results for the calendar year (CY) 2013 monitoring include: (1) the gross alpha and gross beta values from the monitoring stations are approximately equivalent to the highest values observed during the CY2012 reporting at the surrounding Community Environmental Monitoring Program (CEMP) stations (this was the latest documented data available at the time of this writing); (2) only naturally occurring radionuclides were identified in the gamma spectral analyses; (3) the ambient gamma radiation measurements indicate that the average annual gamma exposure is similar at all three monitoring stations and periodic intervals of increased gamma values appear to be associated with storm fronts passing through the area; and (4) the concentrations of both resuspended dust and saltated sand particles generally increase with increasing wind speed. However, differences in the observed dust concentrations are likely due to differences in the soil characteristics immediately adjacent to the monitoring stations. Neither the resuspended particulate radiological analyses nor the ambient gamma radiation measurements suggest wind transport of radionuclide-contaminated soils.

Architecture of gas-hydrate-bearing sands from Walker Ridge 313, Green Canyon 955, and Alaminos Canyon 21: Northern deepwater Gulf of Mexico  

Science Journals Connector (OSTI)

Logging-while-drilling data acquired during the 2009 Gulf of Mexico (GoM) Gas Hydrate Joint Industry Project Leg II program combined with features observed in seismic data allow assessment of the depositional environment, geometry, and internal architecture of gas-hydrate-bearing sand reservoirs from three sites in the northern Gulf of Mexico (GoM): Walker Ridge 313, Alaminos Canyon 21, and Green Canyon 955. The site descriptions assist in the understanding of the geological development of gas-hydrate-bearing sands and in the assessment of their energy production potential. Three sand-rich units are described from the Walker Ridge site, including multiple ponded sand-bodies representing turbidite channel and associated levee and terminal lobe environments within the Terrebonne basin on the lower slope of the GoM. Older units display fewer but greater-reservoir-quality channel and proximal levee facies as compared to thinner, more continuous, and unconfined sheet-like sands that characterize the younger units, suggesting a decrease in depositional gradient with time in the basin. The three wells in the Green Canyon 955 site penetrated proximal levee sands within a previously recognized Late Pleistocene basin floor turbidite-channel-levee complex. Reservoirs encountered in GC955 exhibit thin-bedded internal structure and complex fault compartmentalization. Two wells drilled in the Alaminos Canyon 21 site tested a large, shallow, sand unit within the Diana mini-basin that exhibits steep lateral margins, non-sinuous elongate form, and flat base with hummocky upper surface. These features suggest deposition as a mass-transport deposit consisting of remobilized sand-rich turbidites or as a large basin-floor fan that was potentially eroded and buried by later-stage, mud-prone, mass-transport deposits.

Extended range radiation dose-rate monitor  

DOE Patents [OSTI]

An extended range dose-rate monitor is provided which utilizes the pulse pileup phenomenon that occurs in conventional counting systems to alter the dynamic response of the system to extend the dose-rate counting range. The current pulses from a solid-state detector generated by radiation events are amplified and shaped prior to applying the pulses to the input of a comparator. The comparator generates one logic pulse for each input pulse which exceeds the comparator reference threshold. These pulses are integrated and applied to a meter calibrated to indicate the measured dose-rate in response to the integrator output. A portion of the output signal from the integrator is fed back to vary the comparator reference threshold in proportion to the output count rate to extend the sensitive dynamic detection range by delaying the asymptotic approach of the integrator output toward full scale as measured by the meter.

Supersymmetric inversion of effective-range expansions

A complete and consistent inversion technique is proposed to derive an accurate interaction potential from an effective-range function for a given partial wave in the neutral case. First, the effective-range function is Taylor or Pad\\'e expanded, which allows high precision fitting of the experimental scattering phase shifts with a minimal number of parameters on a large energy range. Second, the corresponding poles of the scattering matrix are extracted in the complex wave-number plane. Third, the interaction potential is constructed with supersymmetric transformations of the radial Schr\\"odinger equation. As an illustration, the method is applied to the experimental phase shifts of the neutron-proton elastic scattering in the $^1S_0$ and $^1D_2$ channels on the $[0-350]$ MeV laboratory energy interval.

Unusual behavior of propane as a co-guest during hydrate formation in silica sand: Potential application to seawater desalination and carbon dioxide capture  

Science Journals Connector (OSTI)

Abstract We report an unusual behavior of hydrate formation in silica sand with gas mixtures containing propane as a co-guest. Based on morphology study we observed that propane as a co-guest has the ability to draw water dispersed in silica sand to the hydrate formation region and showed a tendency to result in drastic hydrate growth due to the migration of water molecules to the gas phase region. Hydrate nucleation occurred in the interstitial pore space between the silica sand particles and hydrate growth occurred in the gas phase above the silica sand bed and to sustain the hydrate growth, dispersed water was drawn towards the hydrate growth front. In addition, we elucidated the effect of sand bed height to maximize the growth rates utilizing this behavior that results in enhanced kinetics. We propose conceptual designs for utilizing this behavior of propane as a co-guest in sand for seawater desalination and an innovative approach to simultaneously capture carbon dioxide and desalinate seawater.

Gravitomagnetism and the Earth-Mercury range  

E-Print Network [OSTI]

We numerically work out the impact of the general relativistic Lense-Thirring effect on the Earth-Mercury range caused by the gravitomagnetic field of the rotating Sun. The peak-to peak nominal amplitude of the resulting time-varying signal amounts to 1.75 10^1 m over a temporal interval 2 yr. Future interplanetary laser ranging facilities should reach a cm-level in ranging to Mercury over comparable timescales; for example, the BepiColombo mission, to be launched in 2014, should reach a 4.5 - 10 cm level over 1 - 8 yr. We looked also at other Newtonian (solar quadrupole mass moment, ring of the minor asteroids, Ceres, Pallas, Vesta, Trans-Neptunian Objects) and post-Newtonian (gravitoelectric Schwarzschild solar field) dynamical effects on the Earth-Mercury range. They act as sources of systematic errors for the Lense-Thirring signal which, in turn, if not properly modeled, may bias the recovery of some key parameters of such other dynamical features of motion. Their nominal peak-to-peak amplitudes are as large as 4 10^5 m (Schwarzschild), 3 10^2 m (Sun's quadrupole), 8 10^1 m (Ceres, Pallas, Vesta), 4 m (ring of minor asteroids), 8 10^-1 m (Trans-Neptunian Objects). Their temporal patterns are different with respect to that of the gravitomagnetic signal.

Signal Fluctuations in the BIFI Range  

Science Journals Connector (OSTI)

Short?term and long?term fluctuation studies have been made in the BIFI Shallow X Water Acoustic Range which is 37 kyd in length. It is shown how time?smear analysis may be used to predict the extent of short?term signal fluctuation by taking into account the energy content of the “front” and “tail” of the received signal. The method is applied to an actual received signal with good results. Long?term fluctuation such as that due to tide is considered in terms of normal mode theory using the results of the time smear analysis to provide an estimate of the relative strengths of the modes. When applied to the BIFI range this method predicts that tidal effects will cause negligible fluctuations in the received signal due to the absence of modes other than the fundamental at this large range. This prediction was verified by experiment. At shorter ranges the interaction of several modes will cause relatively large fluctuations in the signal as the water depth changes during the tidal cycle.

Discussion of long-range weather prediction  

SciTech Connect (OSTI)

A group of scientists at Los Alamos have held a series of discussions of the issues in and prospects for improvements in Long-range Weather Predictions Enabled by Proving of the Atmosphere at High Space-Time Resolution. The group contained the requisite skills for a full evaluation, although this report presents only an informal discussion of the main technical issues. The group discussed all aspects of the proposal, which are grouped below into the headings: (1) predictability; (2) sensors and satellites, (3) DIAL and atmospheric sensing; (4) localized transponders; and (5) summary and integration. Briefly, the group agreed that the relative paucity of observations of the state of the atmosphere severely inhibits the accuracy of weather forecasts, and any program that leads to a more dense and uniform observational network is welcome. As shown in Long-range Weather more dense and uniform observational network is welcome. As shown in Long-range Weather Predictions, the pay-back of accurate long-range forecasts should more than justify the expenditure associated with improved observations and forecast models required. The essential step is to show that the needed technologies are available for field test and space qualification.

Geological characterization and statistical comparison of outcrop and subsurface facies: Shannon shelf sand ridges: Topical report  

SciTech Connect (OSTI)

The primary objective of this research is to develop a methodology for constructing accurate quantitative models of reservoir heterogeneities. The resulting models are expected to improve predictions of flow patterns, spatial distribution of residual oil after secondary and tertiary recovery operations, and ultimate oil recovery. The purpose of this study is to provide preliminary evaluation of the usefulness of outcrop information in characterizing analogous reservoirs and to develop research techniques necessary for model development. The Shannon Sandstone, a shelf sand ridge deposit in the Powder River Basin, Wyoming, was studied. Sedimentologic and petrophysical features of an outcrop exposure of the High-Energy Ridge-Margin facies (HERM) within the Shannon were compared with those from a Shannon sandstone reservoir in Teapot Dome field. Comparisons of outcrop and subsurface permeability and porosity histograms, cumulative distribution functions, correlation lengths and natural logarithm of permeability versus porosity plots indicate a strong similarity between Shannon outcrop and Teapot Dome HERM facies petrophysical properties. Permeability classes found in outcrop samples can be related to crossbedded zones and shaley, rippled, and bioturbated zones. Similar permeability classes related to similar sedimentologic features were found in Teapot Dome field. The similarities of outcrop and Teapot Dome petrophysical properties, which are from the same geologic facies but from different depositional episodes, suggest that rocks deposited under similar depositional processes within a given deposystem have similar reservoir properties. The results of the study indicate that the use of quantitative outcrop information in characterizing reservoirs may provide a significant improvement in reservoir characterization. 17 refs., 5 tabs.

Range of High-Energy Interactions  

Science Journals Connector (OSTI)

The range of high-energy nucleon-nucleon interactions is examined in a simple single inelastic channel model which consists of the production of two spinless isobars. An almost transparent, purely absorbing optical approximation is made, in which case both the inelastic and elastic angular distributions are sensitive to the variation of the absorption coefficient ?l with angular momentum l. Unlike the case of the strong absorber, the inelastic and elastic interactions are described by different effective ranges. Two examples are given, one in which the inelastic channel has an angular distribution characteristic of a one-pion exchange process and the second in which it is characteristic of a "vacuum Regge pole" exchange.

In this paper we report results of a study concerning such determination based on a modification of the canonical model, which admits that pulsars are rotating magnetic dipoles, and on data from the seven pulsars with known braking indices. In order to test the modified model, we predict ranges for the braking indices of other pulsars.

Preparation and evaluation of hydrotreating catalysts based on activated carbon derived from oil sand petroleum coke  

Science Journals Connector (OSTI)

Novel Ni–Mo/activated carbon (AC) hydrotreating catalysts were prepared and evaluated for upgrading heavy vacuum gas oil (HVGO). The AC supports were derived from Alberta oil sand petroleum coke, i.e. fluid coke and/or delayed coke, hereafter referred to as OSP coke, through a chemical process. The BET surface area was as high as 2194 m2/g for the fluid coke derived AC and 2357 m2/g for the delayed coke derived AC. Both \\{ACs\\} contained a large number of micropores with pore volume as high as 1.2 cm3/g. Ni and Mo based active component precursors could be easily loaded on the activated carbon supports by chemical impregnation of nickel nitrate and ammonium molybdate followed by calcination in nitrogen at 773 K without further modification or oxidation treatment to the activated carbons. Scanning electron microscopy (SEM) observation showed highly porous surface structure of the bare activated carbon supports and well dispersed metal (oxide) precursor nanoparticles of 30–50 nm loaded on the AC supports. For comparison, two reference catalysts were also prepared by the same procedure but using commercial activated carbon and porous alumina as supports. After catalyst activation by sulfiding, the hydrotreating performance of the prepared catalysts was evaluated in a magnetically stirred autoclave with a HVGO feedstock to examine their hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) activities. Two commercial hydrotreating catalysts were also tested and compared under similar conditions with the same feed. The results showed that the catalysts based on the activated carbon supports prepared from OSP coke had better hydrotreating performance than the other catalysts. Scanning transmission electron microscopy (STEM) characterization of the catalysts after activation showed that small particles of nanostructure (2–5 nm in size) were evenly embedded in the carbon matrix except for some bigger particles that were located on the catalyst surface. Energy dispersive X-ray (EDX) spectroscopy revealed that these particles were composed of Ni, Mo and S elements. The dispersed nanoparticles formed the active sites and were responsible for the observed high HDS and HDN activity. Elemental analysis and surface characterization of the spent catalysts showed that the formation of coke precursors was favored on the alumina supported catalyst, which resulted in catalyst deactivation.

Yellow perch embryo-larval survival and growth in surface waters associated with oil-sands mining  

SciTech Connect (OSTI)

As part of their land reclamation strategy, Syncrude Canada Ltd. is currently developing environmentally acceptable tailings disposal methods. Fine tailings, a suspension of clay and residual bitumen, is the waste product from oil sands extraction. Fine-tailings contain naphthenic acids, a group of saturated aliphatic and alicyclic carboxylic acids, which occur naturally in petroleum and are partly responsible for the toxicity of process water. The wet landscape method involves covering fine tails with a layer of water such that a self-sustaining ecosystem can be established. A 5 ha demonstration pond with a bottom of fine-tailings was constructed and stocked with yellow perch for experimental purposes. Two other reclaimed ponds formed with oil-sands overburden material were also stocked with perch. Adult perch sampled in the fall of 1995 from the experimental and reclaimed ponds exhibited a 2-fold induction of MFO activity compared to the source lake; indicating organic compound exposure. Perch from one of the reclaimed ponds showed significantly reduced circulating reproductive hormone levels, gonad size and smaller ovarian follicles. Reproductive parameters were not different between the source lake and the remaining ponds. Paired lab and field experiments were conducted to determine if contaminants present would be detrimental to egg viability and development of larvae either through direct exposure of spawned eggs or indirectly by effecting oogenesis. An early life stage toxicity test was also performed using commercially available naphthenic acid standard. Endpoints measured were percent fertilization, percent hatch, mortality, deformities, timing of developmental periods and larval growth.

Tertiary development of heavy oil sands through thermal stimulation in the Wilmington Oil Field, California: A geological perspective  

SciTech Connect (OSTI)

In 1995, a DOE cost share project was initiated to extend thermal recovery in the Tar Zone, Fault Block 11 of the West Wilmington Oil Field, California. The project involved the collection of old oil well data and the construction of a modern digital data base in order to develop a deterministic geological model. The plan was to rigorously define the geology such that horizontal wells could be accurately placed within the sands containing heavy oil to facilitate gravity drainage. A detailed deterministic geological model was constructed using a state of the art 3D mapping and modeling package. Beginning in July, 1995, five observation wells were drilled. Data inconsistencies were revealed when core hole OB2-003 was drilled. It was discovered that the data used to make the maps was corrupted; as a result, the predicted coring point was missed by more than 20'. Significant modifications to the data base were required due to inaccurate subsidence corrections in the original data set. Horizontal wells were then laid out based on the revised data and the geological model was completely reconstructed. Detailed cross sections extracted from the model were use for geosteering. These cross sections proved to be highly accurate and five more wells are now planned for the target sands. This detailed deterministic model will be further refined and combined with our geostatistical mode for geological control in an advanced reservoir simulator. If successful, the thermal stimulation project will be expanded to other fault blocks.

Design of a novel drilled-and-grouted pile in sand for offshore oil&gas structures  

Science Journals Connector (OSTI)

Abstract New offshore oil and gas exploration has placed renewed emphasis on developing structures in relatively complex geological conditions. Due to the damaging nature of impact driving, traditional steel piles used to support jacket structures, are not ideally suited to specific soil types, such as carbonate sands. Drilled and grouted piles are commonly used to support structures in these soil conditions. This paper describes a novel drilled pile, which has been developed specifically to provide a cost effective installation process while maintaining the benefits of grouted piles. The installation process negates the need for temporary casing in weak soils and minimizes the number of offshore operations. In this paper, the installation methodology and post-installation performance of a large scale onshore field trial is described. The installation process was successfully demonstrated with a 1.9 m diameter test pile installed in fine sand to 17.7 m depth in under 3 h. The performance of the pile, as measured in a tension static load test, was shown to compare favorably with existing pile design methods.

Spatial variation of void ratio and shear band thickness in sand using X-ray computed tomography  

SciTech Connect (OSTI)

A detailed study of spatial variation of void ratio and shear band thickness measurements is presented in this paper. A prismatic sand specimen that initially measured 57{center_dot}4 mm wide x 120{center_dot}5 mm long x 182{center_dot}1 mm high was sheared under plane-strain (biaxial) loading conditions. The specimen was prepared at a relative density of 79% using F-75 Ottawa sand. X-ray computed tomography was used to scan the specimen before shearing and after the onset of the shear band. The specimen failed through a single shear band with an inclination angle of 65{center_dot}6{sup o} measured from the direction of the minor principal stress. Computer algorithms were developed to calibrate CT images and quantify void ratio (e) variation within the specimen. CT data analysis revealed cross-sectional spatial variation in void ratio where density is higher in regions close to the edges of the specimen due to membrane effects and confining pressure with no significant variation in void ratio in the axial direction (top to bottom) before shearing. The shear band was easily identified from the CT images, and analysis of void ratio showed a noticeable jump in void ratio profile across the shear band. A detailed statistical summary of the thickness of the shear band and variation of void ratio across the shear band is presented and discussed.

These challenges were highlighted in the NIST workshop report "Aerosol Metrology Needs for Climate Science" (Dec, 2011). Sure, we can capture aerosol particles on surfaces - removing them from their airborne state - and probe them with high resolution optical and chemical imaging tools, but what information do we lose about the airborne particles? How can we follow dynamics? In this talk we will explore these very basic questions and their importance to combustion

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.

Interactions between nitrifying bacteria and hydrocarbon-degrading bacteria during detoxification of oil sands process affected water  

SciTech Connect (OSTI)

Large quantities of process water are produced during the extraction of bitumen from oil sands by the Syncrude and Suncor operations in northern Alberta. Freshly produced tailings water is acutely toxic, but it has been shown to slowly detoxify over time. As detoxification proceeds, there is also a precipitous decrease in ammonia concentrations. The present study examines these two microbially-mediated processes in relation to levels of bacteria and toxicants in mixtures of fresh and aged (detoxified) tailings water. Detoxification of tailings water was greatly accelerated when equal volumes of fresh and detoxified (natural aging for one year) tailings water were mixed. Addition of phosphorus further stimulated detoxification, causing levels of ammonia and naphthenic acids (toxic organic acids leached during bitumen extraction) to decrease to those of detoxified water within two months. Such changes were not observed when phosphorus was not added, or when it was added to less diluted (10-.1 or 3-.1) fresh tailings water. Populations of nitrifying bacteria and naphthenic acid degraders increased markedly in the phosphorus-amended mixtures, but not in its absence. Addition of CS{sub 2} (a specific inhibitor of nitrification) to these mixtures prevented ammonia oxidation. Surprisingly, it also prevented the increase in naphthenic acid-degraders and retarded the loss of naphthenic acids. These results suggest the existence of interactions in fresh tailings water between nitrifying bacteria, naphthenic acid degraders and toxicants. The activity of naphthenic acid-degraders apparently remains low until ammonia is oxidized, whereas that of nitrifying bacteria remains low until concentrations of naphthenic acids or other toxicants decrease below some threshold level. Understanding these interactions may lead to more efficient and effective processes to detoxify oil sands process water.

Use of computed X-ray tomographic data for analyzing the thermodynamics of a dissociating porous sand/hydrate mixture  

SciTech Connect (OSTI)

X-ray computed tomography (CT) is a method that has been used extensively in laboratory experiments for measuring rock properties and fluid transport behavior. More recently, CT scanning has been applied successfully to detect the presence and study the behavior of naturally occurring hydrates. In this study, we used a modified medical CT scanner to image and analyze the progression of a dissociation front in a synthetic methane hydrate/sand mixture. The sample was initially scanned under conditions at which the hydrate is stable (atmospheric pressure and liquid nitrogen temperature, 77 K). The end of the sample holder was then exposed to the ambient air, and the core was continuously scanned as dissociation occurred in response to the rising temperature. CT imaging captured the advancing dissociation front clearly and accurately. The evolved gas volume was monitored as a function of time. Measured by CT, the advancing hydrate dissociation front was modeled as a thermal conduction problem explicitly incorporating the enthalpy of dissociation, using the Stefan moving-boundary-value approach. The assumptions needed to perform the analysis consisted of temperatures at the model boundaries. The estimated value for thermal conductivity of 2.6 W/m K for the remaining water ice/sand mixture is higher than expected based on conduction alone; this high value may represent a lumped parameter that incorporates the processes of heat conduction, methane gas convection, and any kinetic effects that occur during dissociation. The technique presented here has broad implications for future laboratory and field testing that incorporates geophysical techniques to monitor gas hydrate dissociation.

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.

Range-gated field disturbance sensor with range-sensitivity compensation  

DOE Patents [OSTI]

A field disturbance sensor operates with relatively low power, provides an adjustable operating range, is not hypersensitive at close range, allows co-location of multiple sensors, and is inexpensive to manufacture. The sensor includes a transmitter that transmits a sequence of transmitted bursts of electromagnetic energy. The transmitter frequency is modulated at an intermediate frequency. The sequence of bursts has a burst repetition rate, and each burst has a burst width and comprises a number of cycles at a transmitter frequency. The sensor includes a receiver which receives electromagnetic energy at the transmitter frequency, and includes a mixer which mixes a transmitted burst with reflections of the same transmitted burst to produce an intermediate frequency signal. Circuitry, responsive to the intermediate frequency signal indicates disturbances in the sensor field. Because the mixer mixes the transmitted burst with reflections of the transmitted burst, the burst width defines the sensor range. The burst repetition rate is randomly or pseudorandomly modulated so that bursts in the sequence of bursts have a phase which varies. 8 figs.

Wide tracking range, auto ranging, low jitter phase lock loop for swept and fixed frequency systems  

DOE Patents [OSTI]

The present invention provides a wide tracking range phase locked loop (PLL) circuit that achieves minimal jitter in a recovered clock signal, regardless of the source of the jitter (i.e. whether it is in the source or the transmission media). The present invention PLL has automatic harmonic lockout detection circuitry via a novel lock and seek control logic in electrical communication with a programmable frequency discriminator and a code balance detector. (The frequency discriminator enables preset of a frequency window of upper and lower frequency limits to derive a programmable range within which signal acquisition is effected. The discriminator works in combination with the code balance detector circuit to minimize the sensitivity of the PLL circuit to random data in the data stream). In addition, the combination of a differential loop integrator with the lock and seek control logic obviates a code preamble and guarantees signal acquisition without harmonic lockup. An adaptive cable equalizer is desirably used in combination with the present invention PLL to recover encoded transmissions containing a clock and/or data. The equalizer automatically adapts to equalize short haul cable lengths of coaxial and twisted pair cables or wires and provides superior jitter performance itself. The combination of the equalizer with the present invention PLL is desirable in that such combination permits the use of short haul wires without significant jitter.

The effect of low concentrations of assimilable organic carbon (AOC) in water on biological clogging of sand beds  

Science Journals Connector (OSTI)

Infiltration of pretreated surface water with recharge wells is hampered by biological clogging processes in the aquifer. The influence of the concentration of easily assimilable organic carbon (AOC) in water on clogging was investigated in filter beds operated under well-defined laboratory conditions using acetate as a model substrate. Acetate concentrations in the water as low as 0.01 mg C/l promoted clogging with the main head loss, caused by bacterial growth, in the first centimeter of the sand bed. An empirical model was developed describing a linear relationship between the operation period to reach a certain increase in head loss (TPi) and the reciprocal value of the acetate concentration or acetate load [Lac g C/ (m2 · d)] at a constant filtration rate. The rate of clogging, designated as the microbiological clogging factor (Cr), is defined by the slope of the linear relationship between the square root of the increase of the head loss (P112) and the operation time. This linear relationship demonstrated that the increase in clogging rate was constant with time. Observations at several locations with experimental recharge wells revealed that the AOC concentration is an important parameter for the biological clogging potential of water. The AOC concentration of water used for infiltration in a recharge well should be less than 0.01 mg acetate-C equiv/l to prevent biological clogging for a period of more than a year.

Enhanced rate of gas hydrate formation in a fixed bed column filled with sand compared to a stirred vessel  

Science Journals Connector (OSTI)

The performance of two gas/liquid contact modes was evaluated in relation to the rate of gas hydrate formation. Hydrate formation experiments were conducted for several gas mixtures relevant to natural gas hydrate formation in the earth (CH4, CH4/C3H8, CH4/C2H6 and CH4/C2H6/C3H8) and two CO2 capture and storage (CO2, CO2/H2/C3H8). One set of experiments was conducted in a bed of silica sand, saturated with water (fixed fed column) while the other experiment was conducted in a stirred vessel for each gas/gas mixture. Both sets of experiments were conducted at a constant temperature. The rate of hydrate formation is customarily correlated with the rate of gas consumption. The results show that the rate of hydrate formation in the fixed bed column is significantly greater and thereby resulted in a higher percent of water conversion to hydrate in lesser reaction time for all the systems studied.

Analysing sand-dominated channel systems for potential gas-hydrate-reservoirs using an AVO seismic inversion technique on the Southern Hikurangi Margin, New Zealand  

Science Journals Connector (OSTI)

Gas hydrates have recently been recognised as a class of unconventional petroleum resource and the economic viability of gas production from hydrates is now being viewed as a realistic possibility within the next decade. Therefore, potential offshore hydrate accumulations in the world-class endowed gas hydrate province, the Hikurangi Margin, New Zealand, represent a significant medium- to long-term opportunity to meet the country's future energy requirements. In this paper we delineate a potential gas hydrate reservoir in the East Coast Basin, New Zealand and quantitatively estimate its gas hydrate concentrations from 2D seismic data with no well information available. The target is interesting for exploration since it shows evidence for gas-hydrate bearing sands, in particular, buried channel systems. We use a combined analysis of high-resolution velocity analysis, amplitude-versus-offset (AVO) attribute and AVO inversion to investigate whether we can identify regions that are likely to contain highly concentrated gas hydrates and whether they are likely to be sand-dominated. To estimate hydrate concentrations we apply a rock physics model. Our results indicate the presence of several – up to 200 m thick – zones that are likely to host gas hydrates, with one location predicted to consist of high-permeable channel sands and an inferred gas hydrate saturation of ?25%. These findings suggest significant amounts of gas hydrates may be present in high-quality reservoirs on this part of the margin.

Influence of riparian vegetation on channel widening and subsequent contraction on a sand-bed stream since European settlement: Widden Brook, Australia  

Science Journals Connector (OSTI)

Widden Brook in the Hunter Valley, Australia, was first settled by Europeans in 1831 and had widened substantially by the 1870s due to frequent floods during a flood-dominated regime impacting on highly disturbed banks whose riparian trees had been either ringbarked or cleared, and whose understorey had been grazed. Catastrophic floods in 1950 (many), two in August 1952 and one in February 1955 effected the final phase of channel widening at the onset of a second flood-dominated regime more than half a century after the initial widening. Contraction has been active since 1963 by a combination of five biogeomorphic processes. Firstly, rapid channel widening, migration and cutoffs totally reworked the pre-European floodplain and were followed by active floodplain formation. Initial bar formation was replaced by sand splay and overbank deposition which constructed a new floodplain and narrower channel. Secondly, overwidened channel segments that were produced by the catastrophic 1955 flood have contracted since 1963 by the formation of up to four bank-attached, discontinuous benches below the floodplain. Each bench has a bar nucleus of pebbly coarse sand overlain by stratified fine-medium sand and mud. Colonisation by River Sheoaks (Casuarina cunninghamiana subsp. cunninghamiana) or grasses (Cynodon dactylon, Paspalum distichum, Pennisetum clandestinum) is important in converting bars to benches. Thirdly, narrower segments which developed since 1963 have contracted by small-scale accretion on both banks. These deposits are steeply dipping, interbedded sand and mud trapped by stoloniferous and rhizomatous grasses (C. dactylon, P. distichum, P. clandestinum) which also rapidly stabilise the deposits. Fourthly, rare laterally migrating, small radius bends have contracted by recent point bar formation greatly exceeding cutbank recession rates. Point bar formation is controlled by secondary currents producing inclined stratified coarse sands without the influence of vegetation. Lastly, rare, overwidened, non-migrating, large radius bends have greatly contracted by the infilling of dissecting chutes across the convex bank. Establishment of stoloniferous and rhizomatous clonal grasses (Phragmites australis, C. dactylon, P. distichum, P. clandestinum) is important in inducing sedimentation of the chutes. Contraction has produced a much narrower channel than the design width between river training fences which were installed progressively between the 1960s and 1990s. The recent flood history of Widden Brook has not included any catastrophic floods of a size similar to February 1955. Our work demonstrates that both trees and grasses can be associated with narrower channel widths and that the causal link between width and vegetation type is more complex than usually acknowledged.

ESS and Dissipation Range Dynamics of 3-D Turbulence  

E-Print Network [OSTI]

We carry out a self consistent calculation of the structure functions in the dissipation range using Navier Stokes equation. Combining these results with the known structures in the inertial range, we actually propose crossover functions for the structure functions that takes one smoothly from the inertial to the dissipation regime. In the process the success of the extended self similarity is explicitly demonstrated.

Laser Ranging for Gravitational, Lunar, and Planetary Science  

E-Print Network [OSTI]

More precise lunar and Martian ranging will enable unprecedented tests of Einstein's theory of General Relativity and well as lunar and planetary science. NASA is currently planning several missions to return to the Moon, and it is natural to consider if precision laser ranging instruments should be included. New advanced retroreflector arrays at carefully chosen landing sites would have an immediate positive impact on lunar and gravitational studies. Laser transponders are currently being developed that may offer an advantage over passive ranging, and could be adapted for use on Mars and other distant objects. Precision ranging capability can also be combined with optical communications for an extremely versatile instrument. In this paper we discuss the science that can be gained by improved lunar and Martian ranging along with several technologies that can be used for this purpose.

Investigation of operating range in a methanol fumigated diesel engine  

Science Journals Connector (OSTI)

Abstract An experimental study was conducted to investigate the operating range and combustion characteristics in a methanol fumigated diesel engine. The test engine was a six-cylinder, turbocharged direct injection engine with methanol injected into the intake manifold of each cylinder. The experimental results showed that the viable diesel methanol dual fuel (DMDF) operating range in terms of load and methanol substitution percent (MSP) was achieved over a load range from 6% to 100%. The operating range was restricted by four bounds: partial burning, misfire, roar combustion and knock. The lower bound of the operating range was the partial burn bound, which occurred under very low load conditions with high MSP. As the load increased to medium load, MSP reached its maximum value of about 76%, and the onset of misfire provided the right bound for normal operation. At medium to high load, maximum MSP began to decrease. DMDF combustion with excessive MSP was extremely loud with high pressure rise rate, which defined the roar combustion bound. As it increased to nearly full load, measured pressure traces in-cylinder showed strong acoustic oscillations. The appearance of knock provided the upper bound of the operating range. In general, as the load increased, the characters of the combustion changed from partial burn to misfire to roar combustion and to knocking. The range between these four bounds and the neat diesel combustion bound constituted the viable operating range. Over the viable operating range, DMDF combustion worsened the brake thermal efficiency (BTE) at light load while boosted it at medium and high load.
