Molting in Reptiles and Amphibians

Molting in Reptiles and Amphibians Molting in Reptiles and Amphibians Nature Bulletin No. 642-A May 21, 1977 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation MOLTING IN REPTILES AND AMPHIBIANS A snake or a frog sheds its whole skin in one piece in just one day. On the contrary we lose a little of ours every day. Some is worn away and some is soaked loose every time we bathe. We do not realize how fast our skin grows until we have a broken arm or leg and see the crust of dead skin that forms under the case where it cannot be washed or scratched. Hair and feathers are really parts of the skin of mammals and birds. Dogs -- at least house dogs -- shed hair the year round. In contrast, a fur-bearing animal such as a mink loses its thick underfur in spring and grows a new coat before the next winter. Wild birds, as a rule, molt their feathers and replace them a few at a time so that they are always able to fly. Wild ducks and geese, on the other hand, lose all of their night feathers soon after nesting. Then, for a few weeks, while a new set of feathers is growing, they cannot fly. In order to grow, young insects, spiders and crayfish must exchange their tough outer coverings for new and larger ones.

Falling stars: Acoustic influences on meteor detection  

Science Journals Connector (OSTI)

As particles enter the earth's atmosphere they produce a burst of electromagnetic energy including visible and radio-wave emissions. Consequently just as meteors can be detected visually in the night sky they can be heard using radio telescopes. The current project investigated the potential influence of these audio signals on meteor detection. Anecdotally and in related research it has been found that auditory signals can enhance or even alter visual perception of objects. The current project examined the specific effects of accompanying auditory signals on the detection of meteors. Meteors present an interesting case of audiovisual integration in that detection paradigms often entail extended vigilance and extremely brief yet brilliant astronomical events. Experiments specifically investigated how auditory signals that varied in spectra influenced changes in visual magnitude and duration judgments of meteors. In addition research targeted how extraneous auditory cues during a vigilant meteor search might contribute to false judgments. Results are described in terms of audiovisual integration and the relation of perceptual mechanisms to meteor detection.

The Unexpected 2012 Draconid Meteor Storm  

E-Print Network (OSTI)

An unexpected intense outburst of the Draconid meteor shower was detected by the Canadian Meteor Orbit Radar (CMOR) on October 8, 2012. The peak flux occurred at ~16:40 UT on October 8 with a maximum of 2.4 +/- 0.3 hr-1 km-2 (appropriate to meteoroid mass larger than 10-7 kg), equivalent to a ZHRmax = 9000 +/- 1000 using 5-minute intervals, using a mass distribution index of s = 1.88 +/- 0.01 as determined from the amplitude distribution of underdense Draconid echoes. This makes the out- burst among the strongest Draconid returns since 1946 and the highest flux shower since the 1966 Leonid meteor storm, assuming a constant power-law distribution holds from radar to visual meteoroid sizes. The weighted mean geocentric radiant in the time interval of 15-19h UT, Oct 8, 2012 was {\\alpha}g = 262.4 +/- 0.1 deg, {\\delta}g = 55.7 +/- 0.1 deg (epoch J2000.0). Visual observers also reported increased activity around the peak time, but with a much lower rate (ZHR 200), suggesting that the magnitude-cumulative num- ber r...

Meteor showers of comet C/1917 F1 Mellish  

E-Print Network (OSTI)

December Monocerotids and November Orionids are weak but established annual meteor showers active throughout November and December. Analysis of a high quality orbits subset of the SonotaCo video meteor database shows that the distribution of orbital elements, geocentric velocity and also the orbital evolution of the meteors and potential parent body may imply a common origin for these meteors coming from the parent comet C/1917 F1 Mellish. This is also confirmed by the physical properties and activity of these shower meteors. An assumed release of meteoroids at the perihelion of the comet in the past and the sky-plane radiant distribution reveal that the December Monocerotid stream might be younger than the November Orionids. A meteoroid transversal component of ejection velocity at the perihelion must be larger than 100 m/s. A few authors have also associated December Canis Minorids with the comet C/1917 F1 Mellish. However, we did not find any connection.

NHR-23 dependent collagen and hedgehog-related genes required for molting  

SciTech Connect

Highlights: {yields} NHR-23 is a critical regulator of nematode development and molting. {yields} The manuscript characterizes the loss-of-function phenotype of an nhr-23 mutant. {yields} Whole genome expression analysis identifies new potential targets of NHR-23. {yields} Hedgehog-related genes are identified as NHR-23 dependent genes. {yields} New link between sterol mediated signaling and regulation by NHR-23 is found. -- Abstract: NHR-23, a conserved member of the nuclear receptor family of transcription factors, is required for normal development in Caenorhabditis elegans where it plays a critical role in growth and molting. In a search for NHR-23 dependent genes, we performed whole genome comparative expression microarrays on both control and nhr-23 inhibited synchronized larvae. Genes that decreased in response to nhr-23 RNAi included several collagen genes. Unexpectedly, several hedgehog-related genes were also down-regulated after nhr-23 RNAi. A homozygous nhr-23 deletion allele was used to confirm the RNAi knockdown phenotypes and the changes in gene expression. Our results indicate that NHR-23 is a critical co-regulator of functionally linked genes involved in growth and molting and reveal evolutionary parallels among the ecdysozoa.

Structure and dynamics of a complex of cellulose with EDA: insights into the action of amines on cellulose  

SciTech Connect

The neutron structure of a complex of EDA with cellulose has been determined to reveal the location of hydrogen atoms involved in hydrogen bonding. EDA disrupts the hydrogen bonding pattern of naturally occurring cellulose by accepting a strong hydrogen bond from the O6 hydroxymethyl group as the conformation of this group is rotated from tg to gt. The O3-H O5 intrachain hydrogen bond commonly found in cellulose allomorphs is observed to be disordered in the neutron structure, and quantum chemistry and molecular dynamics calculations show that O3 prefers to donate to EDA. The hydrogen bonding arrangement is highly dynamic with bonds continually being formed and broken thus explaining the difficulty in locating all of the hydrogen atoms in the neutron scattering density maps. Comparison with other polysaccharide-amine complexes supports a common underlying mechanism for amine disruption of cellulose.

DYNAMICAL MODEL FOR THE ZODIACAL CLOUD AND SPORADIC METEORS  

SciTech Connect

The solar system is dusty, and would become dustier over time as asteroids collide and comets disintegrate, except that small debris particles in interplanetary space do not last long. They can be ejected from the solar system by Jupiter, thermally destroyed near the Sun, or physically disrupted by collisions. Also, some are swept by the Earth (and other planets), producing meteors. Here we develop a dynamical model for the solar system meteoroids and use it to explain meteor radar observations. We find that the Jupiter Family Comets (JFCs) are the main source of the prominent concentrations of meteors arriving at the Earth from the helion and antihelion directions. To match the radiant and orbit distributions, as measured by the Canadian Meteor Orbit Radar (CMOR) and Advanced Meteor Orbit Radar (AMOR), our model implies that comets, and JFCs in particular, must frequently disintegrate when reaching orbits with low perihelion distance. Also, the collisional lifetimes of millimeter particles may be longer ({approx}> 10{sup 5} yr at 1 AU) than postulated in the standard collisional models ({approx}10{sup 4} yr at 1 AU), perhaps because these chondrule-sized meteoroids are stronger than thought before. Using observations of the Infrared Astronomical Satellite to calibrate the model, we find that the total cross section and mass of small meteoroids in the inner solar system are (1.7-3.5) Multiplication-Sign 10{sup 11} km{sup 2} and {approx}4 Multiplication-Sign 10{sup 19} g, respectively, in a good agreement with previous studies. The mass input required to keep the zodiacal cloud in a steady state is estimated to be {approx}10{sup 4}-10{sup 5} kg s{sup -1}. The input is up to {approx}10 times larger than found previously, mainly because particles released closer to the Sun have shorter collisional lifetimes and need to be supplied at a faster rate. The total mass accreted by the Earth in particles between diameters D = 5 {mu}m and 1 cm is found to be {approx}15,000 tons yr{sup -1} (factor of two uncertainty), which is a large share of the accretion flux measured by the Long Term Duration Facility. The majority of JFC particles plunge into the upper atmosphere at <15 km s{sup -1} speeds, should survive the atmospheric entry, and can produce micrometeorite falls. This could explain the compositional similarity of samples collected in the Antarctic ice and stratosphere, and those brought from comet Wild 2 by the Stardust spacecraft. Meteor radars such as CMOR and AMOR see only a fraction of the accretion flux ({approx}1%-10% and {approx}10%-50%, respectively), because small particles impacting at low speeds produce ionization levels that are below these radars' detection capabilities.

A periodic Energy Decomposition Analysis (pEDA) method for the Investigation of Chemical Bonding in Extended Systems  

E-Print Network (OSTI)

The development and first applications of a new periodic energy decomposition analysis (pEDA) scheme for extended systems based on the Kohn-Sham approach to density functional theory are described. The pEDA decomposes the binding energy between two fragments (e.g. the adsorption energy of a molecule on a surface) into several well-defined terms: preparation, electrostatic and dispersion interaction, Pauli repulsion and orbital relaxation energies. The pEDA presented here for an AO-based implementation can handle restricted and unrestricted fragments for 0D to 3D systems considering periodic boundary conditions with and without the determination of fragment occupations. For the latter case, reciprocal space sampling is enabled. The new method gives comparable results to established schemes for molecular systems and shows good convergence with respect to the basis set (TZ2P), the integration accuracy and k-space sampling. Four typical bonding scenarios for surface adsorbate complexes were chosen to highlight th...

Green power refers to electricity generated from renewable sources, such as solar, wind, biomass, and hydro power. How Does the Green Power Program Work? Otero County Electric Cooperative, Inc. (OCEC) purchases green power at a premium from Tri-State under its Voluntary Renewable Resource Program and then passes the cost of green power on to participating OCEC members. The cost of green power has decreased steadily since the program first started. Initially, it was $2.50 per 100 kWh block. Over the past few years it has been 50 cents and then 9 cents a block. Once again, Tri-State is passing along the reduction in the cost of green power to OCEC. Now, the premium is just 7.5 cents per 100 kWh block. This means that the average household purchasing seven blocks of green power can contribute to renewable energy for just 52.5 cents extra a month.

Meteor observations by the Arecibo 430 \\{MHz\\} incoherent scatter radar. II. Results from time-resolved observations  

Science Journals Connector (OSTI)

We report high time resolution observations using the powerful Arecibo incoherent scatter radar (ISR). The majority of the meteor-like echoes observed lasted less than 50 ms at one range gate, although echoes lasting for a second were also occasionally observed. The latter may not necessarily be associated with meteors. Most of the meteor echoes in our observations have an effective radar cross-section of the order of 3 × 10?8m2, and an estimated electron line density (ELD) of the order of 4 × 109/m. The visual magnitude is approximately + 16, which is about two orders of magnitude fainter than the meteor echoes found in our time-integrated data (Zhou et al., 1995). The average echo power is positively correlated with the number of range bins in which an echo is detected. This characteristic, along with other experimental evidence, strongly suggests that the Arecibo 430 \\{MHz\\} radar is more sensitive to head-on meteors than to those arriving at an oblique angle. Although classical underdense scattering mechanisms may account for echoes having short range extensions, it is clear that they are insufficient to explain echoes having long range extensions. Some possible mechanisms are discussed. In particular, we suggest that Bragg scattering due to the irregular structure existing in a meteor trail is the most important scattering mechanism for the latter type of echoes in our observations. A plasma instability operating near the Arecibo wavelength is required.

Chlorine-36 in Water, Snow, and Mid-Latitude Glacial Ice of North America: Meteoric and Weapons-Tests Production in the Vicinity of the Idaho National Engineering and Environmental Laboratory, Idaho  

SciTech Connect

Measurements of chlorine-36 (36Cl) were made for 64 water, snow, and glacial-ice and -runoff samples to determine the meteoric and weapons-tests-produced concentrations and fluxes of this radionuclide at mid-latitudes in North America. The results will facilitate the use of 36Cl as a hydrogeologic tracer at the Idaho National Engineering and Environmental Laboratory (INEEL). This information was used to estimate meteoric and weapons-tests contributions of this nuclide to environmental inventories at and near the INEEL. The data presented in this report suggest a meteoric source 36Cl for environmental samples collected in southeastern Idaho and western Wyoming if the concentration is less than 1 x 10 7 atoms/L. Additionally, concentrations in water, snow, or glacial ice between 1 x 10 7 and 1 x 10 8 atoms/L may be indicative of a weapons-tests component from peak 36Cl production in the late 1950s. Chlorine-36 concentrations between 1 x 10 8 and 1 x 10 9 atoms/L may be representative of re-suspension of weapons-tests fallout airborne disposal of 36Cl from the INTEC, or evapotranspiration. It was concluded from the water, snow, and glacial data presented here that concentrations of 36Cl measured in environmental samples at the INEEL larger than 1 x 10 9 atoms/L can be attributed to waste-disposal practices.

Carbon Dioxide, Hydrographic, and Chemical Data Obtained During the R/V Meteor Cruise 22/5 in the South Atlantic Ocean (WOCE Section A10, December 1992-January 1993)  

SciTech Connect

This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO{sub 2}) and total alkalinity (TALK) at hydrographic stations, as well as the underway partial pressure of CO{sub 2} (pCO{sub 2}) during the R/V Meteor Cruise 22/5 in the South Atlantic Ocean (Section A10). Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Rio de Janeiro on December 27, 1992, and ended after 36 days at sea in Capetown, South Africa, on January 31, 1993. Measurements made along WOCE Section A10 included pressure, temperature, and salinity [measured by conductivity, temperature, and depth (CTD) sensor], bottle salinity, bottle oxygen, phosphate, nitrate, nitrite, silicate, chlorofluorocarbons (CFC-1 1 , CFC-12), TCO{sub 2}, TALK, and underway pCO{sub 2}. The TCO{sub 2} was measured by using two Single-Operator Multiparameter Metabolic Analyzers (SOMMAs) for extracting CO{sub 2} from seawater samples that were coupled to a coulometer for detection of the extracted CO{sub 2}. The overall precision and accuracy of the analyses was {+-} 1.9 {micro}mol/kg. Samples collected for TALK were measured by potentiometric titration; precision was {+-}2.0 {micro}mol/kg. Underway pCO{sub 2} was measured by infrared photometry with a precision of {+-} 2.0 {micro}atm. The work aboard the R/V Meteor was supported by the U.S. Department of Energy under contract DE-AC02-76CHOO016, and the Bundesministerium fir Forschung und Technologies through grants 03F0545A and MPG 099/1.

Carbon dioxide, hydrographic, and chemical data obtained during the R/V Meteor Cruise 22/5 in the South Atlantic Ocean (WOCE Section A10, December 1992--January 1993)  

SciTech Connect

This documentation discusses the procedures and methods used to measure total carbon dioxide (TCO{sub 2}), total alkalinity at Hydrographic stations as well as the underway partial pressure of CO{sub 2} (pCO{sub 2}) during the R/V Meteor Cruise M22/5 in the South Atlantic Ocean (Section A10). Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Rio de Janeiro on 27 December 1992, and ended after 36 days at sea in Capetown, South Africa on 31 January 1993. Instructions for accessing the data are provided. TCO{sub 2} was measured using tow automated sample processors for extracting CO{sub 2} from seawater samples which were coupled to a Coulometer for detection of the extracted CO{sub 2}. The overall precision and accuracy of the analyses was {+-} 1.9 {micro}mol/kg. Samples collected for total alkalinity were measured by potentiometric titration; precision was {+-} 2.0 {micro}mol/kg. Underway pCO{sub 2} was measured by Infra Red (IR) Photometry; precision was {+-} 2.0 {micro}atm. From these cruises the large-scale three-dimensional distribution of temperature, salinity, and chemical constituents, including the carbonate system parameters will be mapped. Knowledge of these parameters and their initial conditions will allow determination of heat and water transports as well as carbon transport. An understanding of these transports will contribute to the understanding of processes which are relevant for climate change. This section in the South Atlantic subtropical Gyre is especially relevant for CO{sub 2} transport because it crosses both the Brazil and the Benguela Boundary Currents.

Time-resolved X-ray diffraction microprobe studies of the conversion of cellulose I to ethylenediamine-cellulose I  

SciTech Connect

Structural changes during the treatment of films of highly crystalline microfibers of Cladophora cellulose with ethylenediamine (EDA) have been studied by time-resolved X-ray microprobe diffraction methods. As EDA penetrates the sample and converts cellulose I to EDA-cellulose I, the measured profile widths of reflections reveal changes in the shapes and average dimensions of cellulose I and EDA-cellulose I crystals. The (200) direction of cellulose I is most resistant to EDA penetration, with EDA penetrating most effectively at the hydrophilic edges of the hydrogen bonded sheets of cellulose chains. Most of the cellulose chains in the initial crystals of cellulose I are incorporated into crystals of EDA-cellulose I. The size of the emerging EDA-cellulose I crystals is limited to about half of their size in cellulose I, most likely due to strains introduced by the penetration of EDA molecules. There is no evidence of any gradual structural transition from cellulose I to EDA-cellulose I involving a continuously changing intermediate phase. Rather, the results point to a rapid transition to EDA-cellulose I in regions of the microfibrils that have been penetrated by EDA.

Meteor Soft Landing Meteor Soft Landing Name: Les Status: other Grade: 12+ Location: WA Country: USA Date: Winter 2011-2012 Question: Given the surface speed of the earth (daily rotation, yearly orbit, etc.) in relation to everything, is it possible for a meteor or asteroid at just the right path and speed to make a "soft" landing on the surface? Replies: Les I guess it is possible that a meteor or asteroid would have just the right course and speed to make a soft landing on Earth, but it is highly unlikely. Most meteors and asteroids travel and really high speeds. You see them burn in the atmosphere nightly and very brief streaks of light. Sincere regards, Mike Stewart Les, It would not be possible without risking burning up in the atmosphere. To make a soft landing, the meteor would also have to be able to make a soft launch. Barring energy loss to the atmosphere, energy conservation requires that such a landing work the same in both directions. Such a landing could be no slower than the speed needed to launch the meteor back to where it came from. With energy loss due to the atmosphere, slowing from this necessary speed to a soft landing would probably burn the meteor up. An Apollo spaceship landing without open parachutes is better than a meteor could do.

Multisolvent successive extractive refining of coal  

SciTech Connect

A selected group of commercial solvents, namely, anthracene oil (AO), ethylenediamine (EDA), and liquid paraffin (LP), were used for successive extraction of Assam coal. Hot AO provided a wide range of mixed solvents that dissociate chemically and interact favorably with dissociated and undissociated coal macromolecules (like dissolves like). This resulted in the enhancement of the EDA extractability of the AO-pretreated residual coal. EDA is a good swelling solvent and results in physical dissociation of coal molecules. The residual coal obtained after EDA extraction was subjected to extraction with LP, an H-donor, high-boiling (330--360 C) solvent. LP thermally dissociates coal macromolecules and interacts with the coal at its plastic stage at the free radical pockets. The mechanism and molecular dynamics of the multisolvent successive extraction of Assam coal using AO-EDA-LP solvents are discussed. In early attempts, successive extractions did not modify the extraction yield in the single solvent showing the maximum extraction. However, the AO-EDA-LP extraction resulted in the extraction of 70% coal, more than for any of the individual solvents used. Therefore, AO-EDA-LP extraction of coal affords a process yielding a superclean, high-heating value fuel from coal under milder conditions. Several uses of superclean coal have been recommended. Present studies have revealed a new concept concerning the structure of coal having 30% polyaromatic condensed entangled rings and 70% triaromatic-heterocyclic-naphthenic-aliphatic structure. The insolubility of coal is due to the polyfunctional-heterocyclic-condensed structure having a polyaromatic core with intermacromolecular entanglements.

Verifiable process monitoring through enhanced data authentication.  

SciTech Connect

To ensure the peaceful intent for production and processing of nuclear fuel, verifiable process monitoring of the fuel production cycle is required. As part of a U.S. Department of Energy (DOE)-EURATOM collaboration in the field of international nuclear safeguards, the DOE Sandia National Laboratories (SNL), the European Commission Joint Research Centre (JRC) and Directorate General-Energy (DG-ENER) developed and demonstrated a new concept in process monitoring, enabling the use of operator process information by branching a second, authenticated data stream to the Safeguards inspectorate. This information would be complementary to independent safeguards data, improving the understanding of the plant's operation. The concept is called the Enhanced Data Authentication System (EDAS). EDAS transparently captures, authenticates, and encrypts communication data that is transmitted between operator control computers and connected analytical equipment utilized in nuclear processes controls. The intent is to capture information as close to the sensor point as possible to assure the highest possible confidence in the branched data. Data must be collected transparently by the EDAS: Operator processes should not be altered or disrupted by the insertion of the EDAS as a monitoring system for safeguards. EDAS employs public key authentication providing 'jointly verifiable' data and private key encryption for confidentiality. Timestamps and data source are also added to the collected data for analysis. The core of the system hardware is in a security enclosure with both active and passive tamper indication. Further, the system has the ability to monitor seals or other security devices in close proximity. This paper will discuss the EDAS concept, recent technical developments, intended application philosophy and the planned future progression of this system.

Computer aids for electronic equipment design — 21 years on  

Science Journals Connector (OSTI)

In 1968, Eric Wolfendale wrote an article entitled ‘Computer aids for electronic equipment design’ in the first issue of Computer-Aided Design. At the time Wolfendale led a team within Racal Research Ltd that was investigating the possibilities for automating aspects of the process of designing electronic equipment. In the intervening twenty years, Wolfendale's research team has transformed itself into a supplier of electronic design automation (EDA) systems, the Racal Redac Group. Reading Wolfendale's article now is an enlightening task, because it reveals that while substantial progress has been made in developing software to support EDA, the pioneers in the field had clearly identified most, if not all, of the major issues.

Characterization of core and edge turbulence in L- and enhanced D{sub {alpha}} H-mode Alcator C-Mod plasmas  

SciTech Connect

The recently upgraded phase-contrast imaging (PCI) diagnostic is used to characterize the transition from the low (L) to the enhanced D{sub {alpha}} (EDA) high (H) confinement mode in Alcator C-Mod [I. H. Hutchinson, R. Boivin, F. Bombarda et al., Phys. Plasmas 1, 1511 (1994)] plasmas. PCI yields information on line integrated density fluctuations along vertical chords. The number of channels has been increased from 12 to 32 and the sampling rate from 1 MHz to 10 MHz. This expansion of diagnostic capabilities is used to study broadband turbulence in L and EDA H mode and to analyze the quasicoherent (QC) mode associated with EDA H mode. Changes in broadband turbulence at the transition from L to EDA H mode can be interpreted as an effect of the Doppler rotation of the bulk plasma. Additional fluctuation measurements of D{sub {alpha}} light and the poloidal magnetic field show features correlated with PCI in two different frequency ranges at the transition. The backtransition from EDA H to L mode, the so-called enhanced neutron (EN) mode, is investigated by new high frequency (132 and 140 GHz) reflectometer channels operating in the ordinary (O) mode. This additional hardware has been installed in an effort to study localized turbulence associated with internal transport barriers (ITBs). The EN mode is a suitable candidate for this study, since an ITB exists transiently as the outer density decreases much faster than the core density in this mode. The fact that the density decays from the outside inward allows us to study fluctuations progressing towards the plasma core. Our results mark the first localized observation of the QC mode at medium density: 2.2x10{sup 20} m{sup -3} (132 GHz). Correlating the reflectometry measurements with other fluctuating quantities provides some insight regarding the causality of the EN-mode development.

Measured commercial load shapes and energy-use intensities and validation of the LBL end-use disaggregation algorithm. Final report  

SciTech Connect

The Southern California Edison Company (SCE) has conducted an extensive metering project in which electricity end use in 53 commercial buildings in Southern California has been measured. The building types monitored include offices, retail stores, groceries, restaurants, and warehouses. One year (June 1989 through May 1990) of the SCE measured hourly end-use data are reviewed in this report. Annual whole-building and end-use energy use intensities (EUIs) and monthly load shapes (LSs) have been calculated for the different building types based on the monitored data. This report compares the monitored buildings` EUIs and LSs to EUIs and LSs determined using whole-building load data and the End-Use Disaggregation Algorithm (EDA). Two sets of EDA determined EUIs and LSs are compared to the monitored data values. The data sets represent: (1) average buildings in the SCE service territory and (2) specific buildings that were monitored.

Origin of the oil-field brines in the Paris basin  

SciTech Connect

From Br{sup {minus}}/Cl{sup {minus}} ratios coupled with stable-isotope compositions, the components of deep sedimentary brines - namely, primary and secondary brines (from dissolving evaporites) and diluting waters of meteoric origin - can be identified, and in favorable cases, their respective proportions can be quantified. Dilution of primary marine brines (mother liquors of halite) by meteoric waters has occurred in the Dogger and the Keuper aquifers. The presence of highly saline brines (molality of Cl{sup {minus}} = 3.9) in the Rhaetian aquifer may be due to dissolution of primary marine halite by sea water with minor contributions of primary brines. The resulting mixture is diluted by meteoric circulation.

A new approach to estimate commercial sector end-use load shapes and energy use intensities  

SciTech Connect

We discuss the application of an end-use load shape estimation technique to develop annual energy use intensities (EUIs) and hourly end-use load shapes (LSs) for commercial buildings in the Pacific Gas and Electric Company (PG&E) service territory. Results will update inputs for the commercial sector energy and peak demand forecasting models used by PG&E and the California Energy Commission (CEC). EUIs were estimated for 11 building types, up to 10 end uses, 3 fuel types, 2 building vintages, and up to 5 climate regions. The integrated methodology consists of two major parts. The first part is the reconciliation of initial end-use load-shape estimates with measured whole-building load data to produce intermediate EUIs and load shapes, using LBL`s End-use Disaggregation Algorithm, EDA. EDA is a deterministic hourly algorithm that relies on the observed characteristics of the measured hourly whole-building electricity use and disaggregates it into major end-use components. The end-use EUIs developed through the EDA procedure represent a snap-shot of electricity use by building type and end-use for two regions of the PG&E service territory, for the year that disaggregation is performed. In the second part of the methodology, we adjust the EUIs for direct application to forecasting models based on factors such as climatic impacts on space-conditioning EUIs, fuel saturation effects, building and equipment vintage, and price impacts. Core data for the project are detailed on-site surveys for about 800 buildings, mail surveys ({approximately}6000), load research data for over 1000 accounts, and hourly weather data for five climate regions.

Numerical investigation of edge plasma phenomena in an enhanced D-alpha discharge at Alcator C-Mod: Parallel heat flux and quasi-coherent edge oscillations  

SciTech Connect

Reduced-model scrape-off layer turbulence (SOLT) simulations of an enhanced D-alpha (EDA) H-mode shot observed in the Alcator C-Mod tokamak were conducted to compare with observed variations in the scrape-off-layer (SOL) width of the parallel heat flux profile. In particular, the role of the competition between sheath- and conduction-limited parallel heat fluxes in determining that width was studied for the turbulent SOL plasma that emerged from the simulations. The SOL width decreases with increasing input power and with increasing separatrix temperature in both the experiment and the simulation, consistent with the strong temperature dependence of the parallel heat flux in balance with the perpendicular transport by turbulence and blobs. The particularly strong temperature dependence observed in the case analyzed is attributed to the fact that these simulations produce SOL plasmas which are in the conduction-limited regime for the parallel heat flux. A persistent quasi-coherent (QC) mode dominates the SOLT simulations and bears considerable resemblance to the QC mode observed in C-Mod EDA operation. The SOLT QC mode consists of nonlinearly saturated wave-fronts located just inside the separatrix that are convected poloidally by the mean flow, continuously transporting particles and energy and intermittently emitting blobs into the SOL.

Regional ground-water mixing and the origin of saline fluids: Midcontinent, United States  

SciTech Connect

Ground waters in three adjacent regional flow systems in the midcontinent exhibit extreme chemical and isotopic variations that delineate large-scale fluid flow and mixing processes and two distinct mechanisms for the generation of saline fluids. Systematic spatial variations of major ion concentrations, H, O, and Sr isotopic compositions, and ground-water migration pathways indicate that each flow system contains water of markedly different origin. Mixing of the three separate ground waters exerts a fundamental control on ground-water composition. The three ground waters are: (i) dilute meteoric water recharged in southern Missouri; (ii) saline Na-Ca-Cl water in southeastern Kansas of far-traveled meteoric origin that acquired its salinity by halite dissolution; and (iii) Na-Ca-Cl brines in north-central Oklahoma that may have originated as Paleozoic seawater. 45 refs., 4 figs., 1 tab.

Improved user interface design for site selection modeling system  

SciTech Connect

The Site Selection Modeling System (SSMS) is a customized application within the Environmental Data Atlas (EDA), which is an integrated geographic information system (GIS) for environmental applications at the Savannah River site (SRS) developed jointly by the Environmental Sciences Section (ESS) of Westinghouse Savannah River Company and by the University of South Carolina (USC). The SSMS was developed to assist analysts with site selection activities carried out by the ESS and is a powerful tool with a graphical user interface that allows non-GIS analysts to use the application. However, use of the SSMS in recent siting exercises revealed deficiencies in the user interface as a production tool. This paper specifies user interface design criteria necessary for a production application and describes the implementation of these design criteria in the SSMS.

Final Draft of RACER Audit  

SciTech Connect

This document describes the approach Waste and Environmental Services - Environmental Data and Analysis plans to take to resolve the issues presented in a recent audit of the WES-EDA Environmental Database relative to the RACER database. A majority of the issues discovered in the audit will be resolved in May 2011 when the WES-EDA Environmental Database, along with other LANL databases, are integrated and moved to a new vendor providing an Environmental Information Management (EIM) system that allows reporting capabilities for all users directly from the database. The EIM system will reside in a publicly accessible LANL cloud-based software system. When this transition occurs, the data quality, completeness, and access will change significantly. In the remainder of this document, this new structure will be referred to as the LANL Cloud System In general, our plan is to address the issues brought up in this audit in three ways: (1) Data quality issues such as units and detection status, which impinge upon data usability, will be resolved as soon possible so that data quality is maintained. (2) Issues requiring data cleanup, such as look up tables, legacy data, locations, codes, and significant data discrepancies, will be addressed as resources permit. (3) Issues associated with data feed problems will be eliminated by the LANL Cloud System, because there will be no data feed. As discussed in the paragraph above, in the future the data will reside in a publicly accessible system. Note that report writers may choose to convert, adapt, or simplify the information they receive officially through our data base, thereby introducing data discrepancies between the data base and the public report. It is not always possible to incorporate and/or correct these errors when they occur. Issues in the audit will be discussed in the order in which they are presented in the audit report. Clarifications will also be noted as the audit report was a draft document, at the time of this response.

Automating Risk Assessments of Hazardous Material Shipments for Transportation Routes and Mode Selection  

SciTech Connect

The METEOR project at Idaho National Laboratory (INL) successfully addresses the difficult problem in risk assessment analyses of combining the results from bounding deterministic simulation results with probabilistic (Monte Carlo) risk assessment techniques. This paper describes a software suite designed to perform sensitivity and cost/benefit analyses on selected transportation routes and vehicles to minimize risk associated with the shipment of hazardous materials. METEOR uses Monte Carlo techniques to estimate the probability of an accidental release of a hazardous substance along a proposed transportation route. A METEOR user selects the mode of transportation, origin and destination points, and charts the route using interactive graphics. Inputs to METEOR (many selections built in) include crash rates for the specific aircraft, soil/rock type and population densities over the proposed route, and bounding limits for potential accident types (velocity, temperature, etc.). New vehicle, materials, and location data are added when available. If the risk estimates are unacceptable, the risks associated with alternate transportation modes or routes can be quickly evaluated and compared. Systematic optimizing methods will provide the user with the route and vehicle selection identified with the lowest risk of hazardous material release. The effects of a selected range of potential accidents such as vehicle impact, fire, fuel explosions, excessive containment pressure, flooding, etc. are evaluated primarily using hydrocodes capable of accurately simulating the material response of critical containment components. Bounding conditions that represent credible accidents (i.e; for an impact event, velocity, orientations, and soil conditions) are used as input parameters to the hydrocode models yielding correlation functions relating accident parameters to component damage. The Monte Carlo algorithms use random number generators to make selections at the various decision points such as; crash, location, etc. For each pass through the routines, when a crash is randomly selected, crash parameters are then used to determine if failure has occurred using either external look up tables, correlations functions from deterministic calculations, or built in data libraries. The effectiveness of the software was recently demonstrated in safety analyses of the transportation of radioisotope systems for the US Dept. of Energy. These methods are readily adaptable to estimating risks associated with a variety of hazardous shipments such as spent nuclear fuel, explosives, and chemicals.

Porosity prediction in sandstones using erosional unconformities  

SciTech Connect

Erosional unconformities of subaerial origin are created by tectonic uplifts and eustatic sea level fall. Most erosional unconformities developed on sandstones are planes of increased porosity because uplifted sandstones are exposed to undersaturated CO/sub 2/-charged meteoric waters that result in dissolution of unstable framework grains and cements. The chemical weathering of sandstones is intensified in humid regions by the heavy rainfall, soil zones, lush vegetation, and accompanying voluminous production of organic and inorganic acids. Erosional unconformities are considered hydrologically open systems because of abundant supply of fresh meteoric water and relatively unrestricted transport of dissolved constituents away from the site of dissolution, causing a net gain in porosity near unconformities. Thus, porosity in sandstones tends to increase toward overlying unconformities. Such porosity trends have been observed in hydrocarbon-bearing sandstone reservoirs in Alaska, Algeria, Australia, China, Libya, Netherlands, Norwegian North Sea, Norwegian Sea, and Texas. A common attribute of these reservoirs is that they were all subaerially exposed under heavy rainfall conditions. An empirical model has been developed for the Triassic and Jurassic sandstone reservoirs in the Norwegian North Sea on the basis of the observed relationship that shows an increase in porosity in these reservoirs with increasing proximity to the overlying base of Cretaceous unconformity. An important practical attribute of this model is that it allows for the prediction of porosity in the neighboring undrilled areas by recognizing the base of Cretaceous unconformity in seismic reflection profiles and by constructing subcrop maps.

An important practical attribute of these models is that they allow for the prediction of porosity in frontier areas by recognizing erosional unconformities in seismic reflection profiles and by constructing subcrop maps for underlying sandstones. Hydrocarbon-bearing sandstone reservoirs in Alaska, Algeria, Australia, China, Libya, Netherlands, North Sea, Norwegian Sea, and Texas occur immediately beneath major erosional unconformities.

Radar Observations of the 2011 October Draconid Outburst  

E-Print Network (OSTI)

A strong outburst of the October Draconid meteor shower was predicted for October 8, 2011. Here we present the observations obtained by the Canadian Meteor Orbit Radar (CMOR) during the 2011 outburst. CMOR recorded 61 multi-station Draconid echoes and 179 single-station overdense Draconid echoes (covering the magnitude range of +3 <= MV <= +7) between 16-20h UT on October 8, 2011. The mean radiant for the outburst was determined to be a_g = 261.9o +/- 0.3o, d_g = +55.3o +/- 0.3o (J2000) from observations of the underdense multi-station echoes. This radiant location agrees with model predictions to ~1o . The determined geocentric velocity was found to be ~10-15% lower than the model value (17.0 - 19.1 km s^-1 versus 20.4 km s^-1), a discrepancy we attribute to undercorrection for atmospheric deceleration of low density Draconid meteoroids as well as to poor radar radiant geometry during the outburst peak. The mass index at the time of the outburst was determined to be ~ 1.75 using the amplitude distribut...

9 M.y. record of southern Nevada climate from Yucca Mountain secondary minerals  

SciTech Connect

Yucca Mountain, Nevada, is presently the object of intense study as a potential permanent repository for the Nation`s high-level radioactive wastes. The mountain consists of a thick sequence of volcanic tuffs within which the depth to water table ranges from 500 to 700 meters below the land surface. This thick unsaturated zone (UZ), which would host the projected repository, coupled with the present day arid to semi-arid climate, is considered a favorable attribute of the site. Evaluation of the site includes defining the relation between climate variability, as the input function or driver of site- and regional-scale ground-water flow, and the possible future transport and release of radionuclides to the accessible environment. Secondary calcite and opal have been deposited in the UZ by meteoric waters that infiltrated through overlying soils and percolated through the tuffs. The oxygen isotopic composition ({delta}{sup 18}O values) of these minerals reflect contemporaneous meteoric waters and the {delta}{sup 13}C values reflect soil organic matter, and hence the resident plant community, at the time of infiltration. Recent U/Pb age determinations of opal in these occurrences, coupled with the {delta}{sup 13}C values of associated calcite, allow broadbrush reconstructions of climate patterns during the past 9 M.y.

REDUCING RISK IN LOW-PERMEABILITY GAS FORMATIONS: UNDERSTANDING THE ROCK/FLUID CHARACTERISTICS OF ROCKY MOUNTAIN LARAMIDE BASINS  

SciTech Connect

An anomalous velocity model was constructed for the Wind River Basin (WRB) based on {approx}2000 mi of 2-D seismic data and 175 sonic logs, for a total of 132,000 velocity/depth profiles. Ten cross sections were constructed through the model coincident with known gas fields. In each cross section, an intense, anomalously slow velocity domain coincided with the gas-productive rock/fluid interval. The anomalous velocity model: (1) Easily isolates gas-charged rock/fluid systems characterized by anomalously slow velocities and water-rich rock/fluid systems characterized by normal velocities; and (2) Delineates the regional velocity inversion surface, which is characterized by steepening of the Ro/depth gradient, a significant increase in capillary displacement pressure, a significant change in formation water composition, and acceleration of the reaction rate of smectite-to-illite diagenesis in mixed-layer clays. Gas chimneys are observed as topographic highs on the regional velocity inversion surface. Beneath the surface are significant fluid-flow compartments, which have a gas-charge in the fluid phase and are isolated from meteoric water recharge. Water-rich domains may occur within regional gas-charged compartments, but are not being recharged from the meteoric water system (i.e., trapped water). The WRB is divided into at least two regionally prominent fluid-flow compartments separated by the velocity inversion surface: a water-dominated upper compartment likely under strong meteoric water drive and a gas-charged, anomalously pressured lower compartment. Judging from cross sections, numerous gas-charged subcompartments occur within the regional compartment. Their geometries and boundaries are controlled by faults and low-permeability rocks. Commercial gas production results when a reservoir interval characterized by enhanced porosity/permeability intersects one of these gas-charged subcompartments. The rock/fluid characteristics of the Rocky Mountain Laramide Basins (RMLB) described in this work determine the potential for significant, relatively unconventional, so-called ''basin-center'' hydrocarbon accumulations. If such accumulations occur, they will be characterized by the following critical attributes: (1) Location beneath a regional velocity inversion surface that typically is associated with low-permeability lithologies; (2) Anomalous pressure, both over- and underpressure, and when, less commonly, they appear to be normally pressured, they are not in contact with the meteoric water system; (3) A significant gas component in the regional multiphase fluid-flow system (water-gas-oil) that occurs beneath the regional velocity inversion surface; (4) Domains of intense gas charge (i.e., high gas saturation) within the regional multiphase fluid-flow system; (5) Compartmentalization of the rock/fluid system to a far greater extent beneath the regional velocity inversion surface than above it (i.e., convection of fluids across the regional velocity inversion surface is reduced or eliminated depending on the nature of the capillary properties of the low-permeability rocks associated with the inversion surface); (6) Commercial gas accumulations occurring at the intersection of reservoir intervals characterized by enhanced porosity and permeability and gas-charged domains; (7) Productive intersections of reservoir intervals and gas-charged domains, which are controlled by the structural, stratigraphic, and diagenetic elements affecting the rock/fluid system; and (8) No apparent meteoric water connection with the gas accumulations and gas columns up to several thousand feet in height. Because some of these critical attributes are not associated with conventional hydrocarbon accumulations, a new set of diagnostic tools are required in order to explore for and exploit these types of gas prospects efficiently and effectively. Some of these new diagnostic tools have been discussed in this report; other have been described elsewhere. In order to maximize risk reduction, it is recommended when exploring for these types of gas accu

Low-temperature hydrothermal alteration of intra-caldera tuffs, Miocene Tejeda caldera, Gran Canaria, Canary Islands  

Science Journals Connector (OSTI)

The Miocene Tejeda caldera on Gran Canaria erupted ~ 20 rhyolite–trachyte ignimbrites (Mogán Group 14–13.3 Ma), followed by ~ 20 phonolitic lava flows and ignimbrites (Fataga Group 13–8.5 Ma). Upper-Mogán tuffs have been severely altered immediately within the caldera margin, whereas extra-caldera Mogán ignimbrites, and overlying Fataga units, are apparently unaltered. The altered intra-caldera samples contain minerals characteristic of secondary fluid–rock interaction (clays, zeolites, adularia), and relics of the primary mineral assemblage identified in unaltered ignimbrites (K-feldspar, plagioclase, pyroxene, amphibole, and groundmass quartz). Major and trace-element data indicate that Si, Na, K, Pb, Sr, and Rb, were strongly mobilized during fluid–rock interaction, whereas Ti, Zr, and Nb behaved in a more refractory manner, experiencing only minor mobilization. The ?18O values of the altered intra-caldera tuffs are significantly higher than in unaltered extra-caldera ignimbrites, consistent with an overall low-temperature alteration environment. Unaltered extra-caldera ignimbrites have ?D values between ? 110‰ and ? 173‰, which may reflect Rayleigh-type magma degassing and/or post-depositional vapour release. The ?D values of the altered intra-caldera tuffs range from ? 52‰ to ? 131‰, with ambient meteoric water at the alteration site estimated at ca. ? 15‰. Interaction and equilibration of the intra-caldera tuffs with ambient meteoric water at low temperature can only account for whole-rock ?D values of around ? 45‰, given that ?Dclay–water is ca. ? 30‰ at 100 °C, and decreases in magnitude at higher temperatures. All altered tuff samples have ?D values that are substantially lower than ? 45‰, indicating interaction with a meteoric water source with a ?D value more negative than ? 15‰, which may have been produced in low-temperature steam fumaroles. Supported by numerical modeling, our Gran Canaria data reflect the near-surface, epithermal part of a larger, fault-controlled hydrothermal system associated with the emplacement of the high-level Fataga magma chamber system. In this near-surface environment, fluid temperatures probably did not exceed 200–250 °C.

Design of Electron Cyclotron Heating and Current Drive System of ITER  

SciTech Connect

Since the end of EDA, the design of the Electron Cyclotron Heating and Current Drive (ECH and CD) system has been modified to respond to progress in physics understanding and change of interface conditions. Nominal RF power of 20 MW is shared by four upper launchers or one equatorial launcher RF beams are steered by front steering mirrors providing wide sweeping angle for the RF beam. DC high voltage power supply may be composed of IGBT pulse step modulators because of high frequency modulation and design flexibility to three different types of 170 GHz gyrotrons provided by three parties. The RF power from the 170 GHz gyrotron is transmitted to the launcher by 63.5 mm{phi} corrugated waveguide line and remotely switched by a waveguide switch between the upper launcher and the equatorial launcher. The ECH and CD system has also a start-up sub-system for assist of initial discharge composed of three 127.5 GHz gyrotrons and a dedicated DC high voltage power supply. Three of transmission lines are shared between 170 GHz gyrotron and 127.5 GHz gyrotron so as to inject RF beam for the start-up through the equatorial launcher. R and Ds of components for high power long pulse and mirror steering mechanism have been on-going in the parties to establish a reliable ITER ECH and CD system.

Energetic/alpha particle effects on MHD modes and transport  

SciTech Connect

A nonvariational kinetic-MHD stability code (NOVA-K) has been employed to study TAE stability in TFRR D-T and DIII-D experiments and to achieve understanding of TAE instability drive and damping mechanism. Reasonably good agreement between theory and experiment has been obtained. In these experiments the dominant damping mechanism is due to both the thermal ion Landau damping and/or the beam ion Landau damping. Based on ITER EDA parameters, the TAE modes are expected to be unstable in normal ITER operations. Energetic particle transport has been studied using a test particle code (ORBIT). Energetic particle loss scales linearly with the TAE mode amplitude and can be large for TFRR and DIII-D for {delta}B{sub r}/B > 10{sup {minus}4} due to large banana orbit. From quasi-linear (ORBIT) and nonlinear kinetic-MHD (MH3D-K) simulations the saturation of TAE modes is due to nonlinear wave particle trapping and energetic particle profile modification in both radial and energy space. Finally, a convective bucket transport mechanism by MHD waves with time-dependent frequency is presented. Based on the energy-selective characteristics of the bucket transport mechanism, undesirable particles such as helium ash can be removed from the plasma core efficiently.

Estimates of energy consumption by building type and end use at U.S. Army installations  

SciTech Connect

This report discusses the use of LBNL`s End-use Disaggregation Alogrithm (EDA) to 12 US Army installations nationwide in order to obtain annual estimates of electricity use for all major building types and end uses. The building types include barrack, dining hall, gymnasium, administration, vehicle maintenance, hospital, residential, warehouse, and misc. Up to 8 electric end uses for each type were considered: space cooling, ventilation (air handling units, fans, chilled and hot water pumps), cooking, misc./plugs, refrigeration, exterior and interior lighting, and process loads. Through building simulations, we also obtained estimates of natural gas space heating energy use. Average electricity use for these 12 installations and Fort Hood are: HVAC, misc., and indoor lighting end uses consumed the most electricity (28, 27, and 26% of total[3.8, 3.5, and 3.3 kWh/ft{sup 2}]). Refrigeration, street lighting, exterior lighting, and cooking consumed 7, 7, 3, and 2% of total (0.9, 0.9, 0.4, and 0.3 kWh/ft{sup 2})

Chapter 22 - General Concepts  

Science Journals Connector (OSTI)

Publisher Summary The term Electronic Design Automation (EDA) refers to the tools that are used to design and verify integrated circuits (ICs), printed circuit boards (PCBs), and electronic systems, in general. Over time, these early computer-aided drafting tools evolved into interactive programs that performed integrated circuit layout. Other companies like Racal-Redac, SCI-Cards, and Telesis created equivalent layout programs for printed circuit boards. These integrated circuit and circuit board layout programs became known as Computer-Aided Design (CAD) tools. The companies promoting front-end tools for schematic capture and simulation classed them as Computer-Aided Engineering (CAE). The term “automation” refers to the ability for end-users to augment, customize, and drive the capabilities of electronic design and verification tools by means of a scripting language and associated support utilities. There are a wide variety of programming languages available, but—excepting specialist application areas—the most commonly used by far are traditional C and its object-oriented offspring, C++. A gate-level netlist refers to a circuit representation at the level of individual logic gates, registers, and other simple functions. The netlist will also specify the connections (wires) between the various gates and functions. A component-level netlist refers to a circuit representation at the level of individual components. System programming languages such as C, C++, and Java™ are designed to allow programmers to build data structures, algorithms, and—ultimately—applications from the ground up.

Effect of solution chemistry on water softening using charged nanofiltration membranes  

Science Journals Connector (OSTI)

The negatively charged polyamide thin-film-composite nanofiltration membranes have been used to possibly treat the sodium-enriched water, particularly cooling tower water, to separate hardness producing solute like MgSO4 from univalent salts using ESNA and EDA nanofiltration membranes. The flux declines with increasing ionic strength of the feed solution. Rejection of objectionable hardness producing magnesium ions decreases with increasing ionic strength, a case hopefully not reported earlier, with hardly any change in the rejection of sodium chloride used to maintain the ionic strength of the solutions. The effect of pH has also been studied, which shows that flux decreases whereas rejection increases when the solution pH is either reasonably acidic or alkaline in nature. The rate of change in flux and rejection drops with increasing pH when the ionic strength was kept constant. The method is applied to the treatment of some tap waters, altering the ionic strength and pH, to show the validity of the findings. A good agreement in results confirms the phenomenon of variable rejection of hardness producing ions under different solution chemistry.

Porosity enhancement from chert dissolution beneath Neocomian unconformity: Ivishak Formation, North Slope, Alaska  

SciTech Connect

Secondary porosity caused by chert dissolution is common in the hydrocarbon-producing fluvial facies of the Ivishak Formation (Triassic), North Slope, Alaska. Petrographic observations suggest that macroporosity caused by chert dissolution tends to increase toward the Neocomian unconformity. In the Prudhoe Bay field, a lateral increase in core porosity (from 15% at about 30 km from the unconformity to 30% near the unconformity) and in permeability (from 50 md at about 30 km from the unconformity to 800 md near the unconformity) is evident toward the unconformity. This increase occurs within the fluvial facies (zone 4) of nearly uniform grain size and framework composition (chert litharenite). Major chert dissolution probably took place during the Neocomian uplift when the Ivishak Formation was exposed to acidic meteoric waters in the near-surface environment. 16 figures, 3 tables.

11 - Knowledge Flow in Universities  

Science Journals Connector (OSTI)

In this chapter, a typical American university is chosen as a model for the quantitative analysis for the flow of knowledge in a reasonably well-defined academic setting. Knowledge flow assumes quantifiable patterns and much like the flow and retention of rain water over a given terrain of land; the quality (of teaching) and quantity (number of credit hours) of knowledge retained by students is estimated on a qualitative and quantitative basis. The model presented in this chapter is entirely generic. It can be applied in any center of learning and during any period of training, residency in limited time frame, or even to the evolution of species as they gain survival skills, and build their knowledge potential to survive, another generation, calamity, meteor fall, a catastrophic disaster, or a global nuclear fall-out. Though the probability of outcome is not accurately known, it is still bounded by confidence limits.

Rock-brine chemical interactions. Final report  

SciTech Connect

The results of experimental interaction of powdered volcanic rock with aqueous solutions are presented at temperatures from 200 to 400/sup 0/C, 500 to 1000 bars fluid pressure, with reaction durations of approximately 30 days under controlled laboratory conditions. The aim of this research is to develop data on the kinetics and equilibria of rock solution interactions that will provide insight into the complex geochemical processes attending geothermal reservoir development, stimulation, and reinjection. The research was done in the Stanford Hydrothermal Lab using gold cell equipment of the Dickson design. This equipment inverts the solution rock mixture several times a minute to ensure thorough mixing. Solution samples were periodically withdrawn without interruption of the experimental conditions. The data from these experiments suggests a path dependent series of reactions by which geothermal fluids might evolve from meteoric or magmatic sources.

Thirty-one thermal and nonthermal water samples were collected in Panama by the Instituto de Recursos Hidraulicos y Electrificacion and analyzed by the Earth and Space Sciences Division at Los Alamos National Laboratory to evaluate the geothermal potential of four different areas. Chemical and isotopic analyses were performed on each sample. Because samples from several areas were submitted, the chemistry of the samples is varied, with total dissolved solids of thermal fluids ranging from 900 to nearly 10,000 mg/{ell}. All water samples studied are meteoric in origin, and none of the thermal waters exhibit an {sup 18}O enrichment, which is characteristic of high-temperature isotopic, exchange between water and rock. At all four areas, calculated geothermometer temperatures within a reservoir of less than 160{degrees}C. 4 refs., 4 figs., 6 tabs.

OT 060420: A Seemingly Optical Transient Recorded by All-Sky Cameras  

E-Print Network (OSTI)

We report on a ~5th magnitude flash detected for approximately 10 minutes by two CONCAM all-sky cameras located in Cerro Pachon - Chile and La Palma - Spain. A third all-sky camera, located in Cerro Paranal - Chile did not detect the flash, and therefore the authors of this paper suggest that the flash was a series of cosmic-ray hits, meteors, or satellite glints. Another proposed hypothesis is that the flash was an astronomical transient with variable luminosity. In this paper we discuss bright optical transient detection using fish-eye all-sky monitors, analyze the apparently false-positive optical transient, and propose possible causes to false optical transient detection in all-sky cameras.

Diagenetic history of Missourian (Upper Pennsylvanian) Chanute Shale, Cherokee Shelf, midcontinent U. S. A  

SciTech Connect

The Chanute (Ch) Shale consists of two sandstone bodies deposited in fluvial deltaic complexes separated by a shale unit and a coal. The lower Ch is characterized by very fine-to-medium-grained sandstone that fill channels at its base, while the upper Ch includes silt-to-fine-grained sandstone bodies. Petrographic analyses of both units show that they consist of quartz arenites, subarkose, sublitharenite, feldspathic litharenites, litharenites and wackes of the same compositions. Silica-supersaturated waters in the meteoric regime cemented the Ch sands creating thin and discontinuous overgrowths on detrital quartz grains. Early calcite cement precipitated afterwards, inhibiting further silica cementation and shielding feldspars and other liable grains from extensive dissolution. A change in the composition of the meteoric waters caused calcite dissolution leaving patches of cement. As Ch sands entered the compactional regime, saline and alkaline waters dissolved quartz grains and overgrowths as well as other liable grains no longer shielded by the early carbonate cement. The absence of cements and continued compaction resulted in concave-convex and sutured contacts. Dissolution and alteration of feldspars, alteration of micas to clays, and chloritization of biotite and clays continued in the compactional regime. Acidified waters released from organic matter and coal altered micas and feldspars to kaolinite and other clays, releasing Fe, Mg, and Ca necessary for late precipitation of ankerite, dolomite, and calcite cements. Extensive clay and Fe oxide coatings formed, filling embayments on the etched grains. During subsequent Pennsylvanian low sea level stands, ground water dissolved most carbonate cements, creating secondary porosity. Porosity was further enhanced on the outcrop belt during weathering, leaving higher total Fe oxide content on surface samples compared to core samples.

Depositional setting and sandstone diagenesis of the Upper Pennsylvanian (Missourian) Hepler Formation, Cherokee Shelf of the midcontinent  

SciTech Connect

The Hepler Formation marks the base of the Pleasanton Group which is recognized as the base of the Upper Pennsylvanian in southeastern Kansas. This formation consists of interstratified units of shales, siltstones, and sandstones, as well as a localized coal bed. These lithologies are interpreted as having formed in a prograting, fluvially-dominated deltaic sequence that was deposited as the Late Pennsylvanian sea temporarily withdrew from the Cherokee shelf. Hepler sandstone bodies in the study area are predominantly quartz arenites and sublitharenites. The diagenetic history of the Hepler consisted of alternating periods of authigenic mineral precipitation and dissolution of both detrital grains and cements. Petrographic observations indicate that silica cementation, in the form of quartz overgrowths, took place early in the paragenetic sequence. Changes in the meteoric water chemistry, resulted in partial quartz and feldspar dissolution, and alteration of feldspars to clays. Precipitation of carbonate into dissolution features was initiated by acidic surface waters (fluvial) followed by a sea level rise allowing carbonate-saturated marine waters to flush these sediments. Further burial and compaction destroyed much of remaining porosity and left concavo-convex contacts and sutured quartz grains. This was followed by anoxic conditions which allowed pyrite crystallization to take place. A subsequent fall in sea level exposed Hepler deposits once again to meteoric, low pH waters, resulting in carbonate dissolution. All observed porosity is secondary, formed by carbonate dissolution. Surface samples were subjected to weathering of iron-bearing components to iron-oxide, a product not observable in subsurface core samples.

Inversion of reservoir quality: An example from the Triassic Buntsandstein, offshore Netherlands  

SciTech Connect

Sandstones from the Triassic Main Buntsandstein form a major gas reservoir in the Netherlands offshore. The sequence is dominated by siliciclastics deposited in an arid continental setting, and include dune, interdune, sheetsand, and fluvial sandstones. Reduction in reservoir quality is caused primarily by dolomite, halite, and anhydrite cementation, with minor authigenic illite and chlorite. Integration of petrographic and isotopic data has allowed the origins and relative timing of the different cements to be constrained. The carbon and oxygen isotopic composition of dolomite ([delta][sup 13]C = -3.76 to -9.3%, [delta][sup 18]O = -3 to +2.9% PDB) combined with strontium isotopic data (0.7091 to 0.7109 [sup 86]Sr/[sup 87]Sr) suggest that is precipitated from meteoric groundwater. Halite and anhydrite formed from a mixture of meteoric water and saline fluids expelled from underlying evaporites and claystones. Sulfur isotopic data (+4.2 to +12.1 CDT) support6 this interpretation for the origin of the anhydrite. Precipitation of the major authigenic minerals occurred during early diagenesis, prior to burial depths of 500 m. Cementation and groundwater flow followed the zones of highest permeability and caused an inversion of reservoir quality. Sandstones with the highest depositional porosity and permeability (i.e., dune sandstones) are the most cemented, and have poorer reservoir quality compared to the fluvial and interdune sandstones, which originally had lower depositional porosity/permeability. Formation of authigenic illite and chlorite occurred during burial and has significantly reduced permeability. Information on the depositional settings and paleogeography, combined with expected groundwater flow, has helped define potential exploration areas of reduced reservoir quality as a result of extensive early cementation.

Ordovician carbonate formation waters in the Illinois Basin: Chemical and isotopic evolution beneath a regional aquitard  

SciTech Connect

Formation waters from carbonate reservoirs in the upper Ordovician Galena Group of the Illinois Basin have been analyzed geochemically to study origin of salinity, chemical and isotopic evolution, and relation to paleohydrologic flow systems. These carbonate reservoirs underlie the Maquoketa Shale Group of Cincinnatian age, which forms a regional aquitard. Cl-Br relations and Na/Br-Cl/Br systematics indicate that initial brine salinity resulted from subaerial evaporation of seawater to a point not significantly beyond halite saturation. Subsequent dilution in the subsurface by meteoric waters is supported by delta D-delta O-18 covariance. Systematic relations between Sr-87/Sr-86 and 1/Sr suggest two distinct mixing events: introduction of a Sr-87 enriched fluid from a siliciclastic source, and a later event which only affected reservoir waters from the western shelf of the basin. The second mixing event is supported by covariance between Sr-87/Sr-86 and concentrations of cations and anions; covariance between Sr and O-D isotopes suggests that the event is related to meteoric water influx. Systematic geochemical relations in ordovician Galena Group formation waters have been preserved by the overlying Maquoketa shale aquitard. Comparison with results from previous studies indicates that waters from Silurian-Devonian carbonate strata evolved in a manner similar to yet distinct from that of the Ordovician carbonate waters, whereas waters from Mississippian-Pennsylvanian strata that overlie the New Albany Shale Group regional aquitard are marked by fundamentally different Cl-Br-Na and Sr isotope systematics. Evolution of these geochemical formation-water regimes apparently has been influenced significantly by paleohydrologic flow systems.

Geophysical exploration in the Lautertal at the Combat Maneuver Training Center, Hohenfels, Germany  

SciTech Connect

Geophysical exploration was conducted in the Lautertal at the Combat Maneuver Training Center, Hohenfels, Germany, to determine the shallow geological framework of a typical dry valley in this karstic environment. The complementary methods of electromagnetic surveying, vertical electrical soundings, and seismic refraction profiling were successful in determining the depth and configuration of the bedrock surface, the character of the unconsolidated deposits resting on the bedrock surface, and the nature of the bedrock surface. Channels and other depressions in the bedrock surface are aligned with structurally induced fractures in the bedrock. The unconsolidated deposits consist of coarse alluvium and colluvium, which are confined to these channels and other depressions, and fine-grained loam and loess, which cover most of the Lautertal. Wide ranges in the electrical and elastic parameters of the bedrock surface are indicative of carbonate rock that is highly fractured and dissolved at some locations and competent at others. Most local groundwater recharge occurs in the uplands where the Middle Kimmeridge (Delta) Member of the Maim Formation (Jurassic) is widely exposed. These carbonate rocks are known to be susceptible to dissolution along the fractures and joints; thus, they offer meteoric waters ready access to the main shallow aquifers lower in the Malm Formation. These same rocks also form the bedrock surface below many of the dry valleys, but in the Lautertal, the infiltration of meteoric waters into the subsurface is generally impeded by the surficial layer of fine-grained loam and loess, which have low hydraulic conductivity. Further, the rocks of the Middle Kimmeridge Member appear to be closely associated with the localized occurrence of turbidity in such perennial streams as the Lauterach.

Uranium mineralization in fluorine-enriched volcanic rocks  

SciTech Connect

Several uranium and other lithophile element deposits are located within or adjacent to small middle to late Cenozoic, fluorine-rich rhyolitic dome complexes. Examples studied include Spor Mountain, Utah (Be-U-F), the Honeycomb Hills, Utah (Be-U), the Wah Wah Mountains, Utah (U-F), and the Black Range-Sierra Cuchillo, New Mexico (Sn-Be-W-F). The formation of these and similar deposits begins with the emplacement of a rhyolitic magma, enriched in lithophile metals and complexing fluorine, that rises to a shallow crustal level, where its roof zone may become further enriched in volatiles and the ore elements. During initial explosive volcanic activity, aprons of lithicrich tuffs are erupted around the vents. These early pyroclastic deposits commonly host the mineralization, due to their initial enrichment in the lithophile elements, their permeability, and the reactivity of their foreign lithic inclusions (particularly carbonate rocks). The pyroclastics are capped and preserved by thick topaz rhyolite domes and flows that can serve as a source of heat and of additional quantities of ore elements. Devitrification, vapor-phase crystallization, or fumarolic alteration may free the ore elements from the glassy matrix and place them in a form readily leached by percolating meteoric waters. Heat from the rhyolitic sheets drives such waters through the system, generally into and up the vents and out through the early tuffs. Secondary alteration zones (K-feldspar, sericite, silica, clays, fluorite, carbonate, and zeolites) and economic mineral concentrations may form in response to this low temperature (less than 200 C) circulation. After cooling, meteoric water continues to migrate through the system, modifying the distribution and concentration of the ore elements (especially uranium).

Electrophilic, Ambiphilic, and Nucleophilic C-H bond Activation: Understanding the electronic continuum of C-H bond activation through transition-state and reaction pathway interaction energy decompositions  

SciTech Connect

The potential energy and interaction energy profiles for metal- and metal?ligand-mediated alkane C?H bond activation were explored using B3LYP density functional theory (DFT) and the absolutely localized molecular orbital energy decomposition analysis (ALMO-EDA). The set of complexes explored range from late transition metal group 10 (Pt and Pd) and group 11 (Au) metal centers to group 7?9 (Ir, Rh, Ru, and W) metal centers as well as a group 3 Sc complex. The coordination geometries, electron metal count (d{sup 8}, d{sup 6}, d{sup 4}, and d{sup 0}), and ligands (N-heterocycles, O-donor, phosphine, and Cp*) are also diverse. Quantitative analysis using ALMO-EDA of both directions of charge-transfer stabilization (occupied to unoccupied orbital stabilization) energies between the metal?ligand fragment and the coordinated C?H bond in the transition state for cleavage of the C?H bond allows classification of C?H activation reactions as electrophilic, ambiphilic, or nucleophilic on the basis of the net direction of charge-transfer energy stabilization. This bonding pattern transcends any specific mechanistic or bonding paradigm, such as oxidative addition, ?-bond metathesis, or substitution. Late transition metals such as Au(III), Pt(II), Pd(II), and Rh(III) metal centers with N-heterocycle, halide, or O-donor ligands show electrophilically dominated reaction profiles with forward charge-transfer from the C?H bond to the metal, leading to more stabilization than reverse charge transfer from the metal to the C?H bond. Transition states and reaction profiles for d{sup 6} Ru(II) and Ir(III) metals with Tp and acac ligands were found to have nearly equal forward and reverse charge-transfer energy stabilization. This ambiphilic region also includes the classically labeled electrophilic cationic species Cp*(PMe{sub 3})Ir(Me). Nucleophilic character, where the metal to C?H bond charge-transfer interaction is most stabilizing, was found in metathesis reactions with W(II) and Sc(III) metal center complexes in reactions as well as late transition metal Ir(I) and Rh(I) pincer complexes that undergo C?H bond insertion. Comparison of pincer ligands shows that the PCP ligand imparts more nucleophilic character to an Ir metal center than a deprotonated PNP ligand. The PCP and POCOP ligands do not show a substantial difference in the electronics of C?H activation. It was also found that Rh(I) is substantially more nucleophilic than Ir(I). Lastly, as a qualitative approximation, investigation of transition-state fragment orbital energies showed that relative frontier orbital energy gaps correctly reflect electrophilic, ambiphilic, or nucleophilic charge-transfer stabilization patterns.

Scale Insects and Mealy Bugs Scale Insects and Mealy Bugs Nature Bulletin No. 404-A January 30, 1971 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation SCALE INSECTS AND MEALY BUGS The insect world contains an enormous number and variety of species but, of them all, the Scale Insects and Mealy Bugs come nearest to being vegetables. Most insects are active animals that fly, hop, scamper, crawl or burrow, but these queer creatures spend most of their lives merely sitting in one spot, sucking plant juices from a branch, twig, leaf, or fruit. Some of our most destructive pests are included among the several hundred kinds of these highly specialized insects. They are so small that the average person seldom realizes that they are responsible for the sickly or dying condition of a tree or shrub. Adult scale insects are extremely variable in shape, and range in size from that of a pinhead up to forms which are a quarter of an inch long. Each hides under a hard protective shell, or scale, of wax secreted by pores on its body, and are frequently so numerous that they form a dense crust. The females molt a few times, and usually discard their legs and wings, before they mature. She lays eggs under the scale and then dies. These hatch into young (called "crawlers") which move around for a period varying from a few hours to a day or two before they settle down and build scales. Unlike the female, the male -always the smaller of the two -- goes through a cocoon stage from which he emerges with a pair of wings but with no means of taking food. He merely mates and dies. Males are scarce In most kinds and in many species have never been seen.

Involvement of FTZ-F1 in the regulation of pupation in Leptinotarsa decemlineata (Say)  

Science Journals Connector (OSTI)

Abstract During the final instar larvae of holometabolous insects, a pulse of 20-hydroxyecdysone (20E) and a drop in juvenile hormone (JH) trigger larval-pupal metamorphosis. In this study, two LdFTZ-F1 cDNAs (LdFTZ-F1-1 and LdFTZ-F1-2) were cloned in Leptinotarsa decemlineata. Both LdFTZ-F1-1 and LdFTZ-F1-2 were highly expressed just before or right after each molt, similar to the expression pattern of an ecdysteroidogenesis gene LdSHD. Ingestion of an ecdysteroid agonist halofenozide (Hal) enhanced LdFTZ-F1-1 and LdFTZ-F1-2 expression in the final larval instar. Conversely, a decrease in 20E by feeding a double-stranded RNA (dsRNA) against LdSHD repressed the expression. Moreover, Hal rescued the expression levels in LdSHD-silenced larvae. Thus, 20E peaks seem to induce the transcription of LdFTZ-F1s. Furthermore, ingesting dsLdFTZ-F1 from a common fragment of LdFTZ-F1-1 and LdFTZ-F1-2 successfully knocked down both LdFTZ-F1s, and impaired pupation. Finally, knocking down LdFTZ-F1s significantly repressed the transcription of three ecdysteroidogenesis genes, lowered 20E titer, and reduced the expression of two 20E receptor genes. Silencing LdFTZ-F1s also induced the expression of a JH biosynthesis gene, increased JH titer, but decreased the mRNA level of a JH early-inducible gene. Thus, LdFTZ-F1s are involved in the regulation of pupation by modulating 20E and JH titers and mediating their signaling pathways.

A microfluidics-based technique for automated and rapid labeling of cells for flow cytometry  

Science Journals Connector (OSTI)

Flow cytometry is a powerful technique capable of simultaneous multi-parametric analysis of heterogeneous cell populations for research and clinical applications. In recent years, the flow cytometer has been miniaturized and made portable for application in clinical- and resource-limited settings. The sample preparation procedure, i.e. labeling of cells with antibodies conjugated to fluorescent labels, is a time consuming (~45 min) and labor-intensive procedure. Microfluidics provides enabling technologies to accomplish rapid and automated sample preparation. Using an integrated microfluidic device consisting of a labeling and washing module, we demonstrate a new protocol that can eliminate sample handling and accomplish sample and reagent metering, high-efficiency mixing, labeling and washing in rapid automated fashion. The labeling module consists of a long microfluidic channel with an integrated chaotic mixer. Samples and reagents are precisely metered into this device to accomplish rapid and high-efficiency mixing. The mixed sample and reagents are collected in a holding syringe and held for up to 8 min following which the mixture is introduced into an inertial washing module to obtain 'analysis-ready' samples. The washing module consists of a high aspect ratio channel capable of focusing cells to equilibrium positions close to the channel walls. By introducing the cells and labeling reagents in a narrow stream at the center of the channel flanked on both sides by a wash buffer, the elution of cells into the wash buffer away from the free unbound antibodies is accomplished. After initial calibration experiments to determine appropriate 'holding time' to allow antibody binding, both modules were used in conjunction to label MOLT-3 cells (T lymphoblast cell line) with three different antibodies simultaneously. Results confirm no significant difference in mean fluorescence intensity values for all three antibodies labels (p

Stable isotope and water quality analysis of coal bed methane production waters and gases from the Bowen Basin, Australia  

Science Journals Connector (OSTI)

Coal bed methane (CBM) is a significant growing industry in Queensland's energy sector. It is, however, a relatively new industry with little local water quality data and stable isotope compositions of production waters and gases available in the public domain. This study aims to determine whether water quality and stable isotope data can be correlated with gas and groundwater production and flow pathways, and identify zones of recharge and water mixing. Stable isotope analysis and accessory water quality tests were conducted on CBM production gas and water samples collected from two CBM producing bituminous coal seams within a single field in the Bowen Basin. In the production field, the reservoir seams are gently folded with eastwardly dipping fold axes, and compartmentalised by an ENE normal fault on the flank of a broad central anticline that contains minor faults. For one seam, splitting and a change in coal quality parallels the fault and fold axes. Although virgin reservoir conditions were similar, differing production performance north and south of the main fault suggests it acts as a barrier to water and gas flow along strike. The stable isotope analysis on the production water showed that waters with more positive ?D and ?18O compositions were associated with areas of higher water production and shallower depths, whereas more negative ?D and ?18O compositions were associated with lower water production and high gas production. The gas isotope analysis showed that production gases had both biogenic and thermogenic origins and that secondary biogenic gas generated through CO2 reduction comprises a significant portion of the CBM produced from this field. More negative CH4 ?13C values characterize the zones of meteoric recharge in shallow, up-dip areas. Gas production data and CO2 ?13C values suggest that this may result from 13CH4 stripping by the recharge waters and/or increased biogenic activity in this area. Smaller CO2–CH4 carbon isotopic fractionation values characterized zones of meteoric recharge, whereas higher isotopic fractionation values characterized the high gas production domain.

Columbus Day Columbus Day Nature Bulletin No. 651 Oct6ober 14, 1961 Forest Preserve District of Cook County John J. Duffy, President Roberts Mann, Conservation Editor David H. Thompson, Senior Naturalist COLUMBUS DAY October 12th, 1492, was a great turning point in history. On that day Christopher Columbus, with 87 men in three small sailing vessels, sighted the low hills of a little island in the West Indies which he named San Salvador. Although he made three more voyages across the Atlantic he never realized that, instead of a route to the Orient, he had discovered a whole New World. With favorable winds they had sailed westward from the Canary Islands for 33 days and nights without sighting land. As they ran before the wind day after day into unknown seas the crews began to grumble that they would starve before they could make their way back to Spain. On the 6th day a brilliant meteor was an ill omen to the superstitious sailors. To quiet their fears somewhat, Columbus kept two ship's logs: a private record of his own showing the true distances traveled, and a second one -- for the crew -- in which each day's run was reduced.

Arun field  

SciTech Connect

The Arun field is a giant gas-condensate field operated by Mobil and Pertamina with over 20,000 acres of closure at the top of the Arun reservoir. A middle-shelf patch reef complex of early to middle Miocene age is the producing facies at the Arun field. About 1,100 ft of porous limestones, encased in shales, create a stratigraphic trap for overpressure hydrocarbons. Three main carbonate lithologies were encountered during the examination of over 4,300 ft of core; (1) a reef facies consisting of vuggy, coral encrusting, red-algal boundstones, (2) a near-reef facies consisting of foraminiferal, mixed-skeletal packstones with gravel-size coral fragments, and (3) an interreef lagoonal facies consisting of benthonic-foram packstones. Twenty-two species of corals have been identified from Arun reef facies; major reef-forming coals, listed in order of decreasing abundance, are Porites cf P. Lutes, Cyphastrea microphthalma, Astreopora myriophthalma, Styloconiella gunetheri, Porites solida, and Acropora ssp. The Arun reef is comprised of limestones (with minor amounts of dolomite). No shale beds occur in the sequence, and all carbonate facies are in communication. A pervasive microporosity, occurring throughout the Arun Limestone, results from meteoric alteration of original carbonate mud to form a microrhombic porosity that accounts for about three-fourths of the field's total porosity.

Water information bulletin No. 30, part 13: geothermal investigations in Idaho. Preliminary geologic reconnaissance of the geothermal occurrences of the Wood River Drainage Area  

SciTech Connect

Pre-tertiary sediments of the Milligen and Wood River Formations consisting primarily of argillite, quartzite, shale and dolomite are, for the most part, exposed throughout the area and are cut locally by outliers of the Idaho Batholith. At some locations, Tertiary-age Challis Volcanics overlay these formations. Structurally the area is complex with major folding and faulting visible in many exposures. Many of the stream drainages appear to be fault controlled. Hydrologic studies indicate hot spring occurrences are related to major structural trends, as rock permeabilities are generally low. Geochemical studies using stable isotopes of hydrogen and oxygen indicate the thermal water in the Wood River region to be depleted by about 10 0/00 in D and by 1 to 2 0/00 in /sup 18/0 relative to cold water. This suggests the water could be meteoric water that fell during the late Pleistocene. The geological data, as well as the chemical data, indicate the geothermal waters are heated at depth, and subsequently migrate along permeable structural zones. In almost all cases the chemical data suggest slightly different thermal histories and recharge areas for the water issuing from the hot springs. Sustained use of the thermal water at any of the identified springs is probably limited to flow rates approximating the existing spring discharge. 28 refs., 16 figs., 3 tabs.

The red rain phenomenon of Kerala and its possible extraterrestrial origin  

E-Print Network (OSTI)

A red rain phenomenon occurred in Kerala, India starting from 25th July 2001, in which the rainwater appeared coloured in various localized places that are spread over a few hundred kilometers in Kerala. Maximum cases were reported during the first 10 days and isolated cases were found to occur for about 2 months. The striking red colouration of the rainwater was found to be due to the suspension of microscopic red particles having the appearance of biological cells. These particles have no similarity with usual desert dust. An estimated minimum quantity of 50,000 kg of red particles has fallen from the sky through red rain. An analysis of this strange phenomenon further shows that the conventional atmospheric transport processes like dust storms etc. cannot explain this phenomenon. The electron microscopic study of the red particles shows fine cell structure indicating their biological cell like nature. EDAX analysis shows that the major elements present in these cell like particles are carbon and oxygen. Strangely, a test for DNA using Ethidium Bromide dye fluorescence technique indicates absence of DNA in these cells. In the context of a suspected link between a meteor airburst event and the red rain, the possibility for the extraterrestrial origin of these particles from cometary fragments is discussed.

Evaporite diagenesis driven by synsedimentary evolution of brines  

SciTech Connect

Back-reaction of brines has modified cyclic shallow water carbonate-sulfate-halite sequences (Permian) in the Palo Duro basin, Texas Panhandle. Successive parts of regressive evaporite cycles were deposited from progressively more highly evaporated seawater. The reaction of the brine with sediments deposited during earlier parts of each cycle was the major force criving diagenetic reactions and determining the final mineralogy. Normal marine limestones at the base of cycles were dolomitized in the shallow subsurface environments by brines that precipitated brine-pool evaporites in the upper parts of cycles. Gypsum dehydrated to anhydrite at burial depths of 1-2m beneath the brine-pool floor as brine salinity increased toward halite saturation. Diagenetic limpid dolomite and anhydrite replacing halite were probably derived from mixed meteoric and evaporated-marine brines squeezed from mudstone beds during compaction in the shallow subsurface. Anhydrite and halite pervasively cemented and partly replaced carbonates and gypsum. The resulting low permeability limited later diagenetic alteration, so that the early diagenetic textures and mineralogy were preserved in the burial environment. Reduction in permeability occurred before the transgression initiating the next cycle; the only major result of the introduction of seawater into the evaporite environment was dissolution of the last-deposited few meters of halite.

Petrographic and geochemical constraints on the deposition and diagenesis of the Haynesville Formation (Upper Jurassic), southwestern Alabama  

SciTech Connect

The Haynesville Formation in Clarke County, southwestern Alabama, is a 250 m thick, halite-dominated evaporite rock composed of four vertically stacked evaporite facies. The different facies present include a basal chevron-dominated unit, a gray cumulate unit, a unit dominated by brown, organic-rich cumulates, and a unit composed of halite and anhydrite interbedded with sand and mud. The facies are defined by halite textures, the presence of anhydrite laminae and dissolution surfaces, and the relative amount of terrigenous material. These criteria were used because they provide some constraint on the brine depths present during precipitation of the salt. The integration of geochemical data with petrographic observations has been used to formulate a model for the deposition and diagenesis of the deposits. The bromide concentrations within the basal chevron zone systematically rise from 36 ppm to 101 ppm, while the bromide concentrations within the overlying cumulate zone rise more rapidly from 121 ppm to 440 ppm. The strontium isotopic composition of the salt over this interval systematically increases from 0.7068 to 0.7084. Bromide concentrations, strontium isotope ratios, and other chemical parameters, in combination with petrographic observations, constrain the relative importance of depositional and diagenetic processes. Processes that are important in controlling the geochemistry of the deposits include the influx of seawater and meteoric fluid into the basin, synsedimentary dissolution and recycling of solutes, the reflux of brines within the basin, and burial diagenetic processes.

Salt diffusion in interstitial waters and halite removal from sediments: Examples from the Red Sea and Illinois basins  

SciTech Connect

Large thicknesses of bedded halite can be removed in subsiding sedimentary basins by verticla diffusion of dissolved salt in interstitial waters over geologic time scales. Calculations show that at least 10 m to 40 m of halite may have dissolved and diffused through the Red Sea sediments overlying the salt beds, since cessation of salt deposition approximatley 5.3 million years ago. The total amount of salt diffused out of the sediment column over geologic time is five to twenty times the amount of salt that currently exists in the porewater column. If upward flow in the past occurred at even small rates, 10{sup {minus}3} m/yr, the amount of halite removed could have been ten times as great, 500 m. Unlike the Red Sea Basin, no halite beds are known in the Illinois Basin in spite of the fact that interstitial waters with as much as 200{per thousand} TDS (approximately 220 g/L) occur. Calculations show that if a halite bed had been deposited at the base of the Illinois Basin in Cambrian time, it would have been completely removed from the stratigraphic record had it initially been less than 60 m to 130 m in thickness. A significant thickness of halite deposited in sedimentary basins may thus be removed during active burial of salt beds, and before exhumation and exposure of the salt beds to shallow meteoric waters.

Water salinity of the First Eocene reservoir: Its unique behaviour and influence on reservoir engineering calculations  

SciTech Connect

The salinity of the produced water from First Eocene reservoir of Wafra field was studied through its past history. The change in the salinity of the initially produced water (from about 500 to 20,000 ppm NaCl) was attributed to the meteoric water which might have entered the reservoir through its outcrops to the west of the field. The correct value of the connate water salinity (23,000 ppm) that should be used in estimating the original oil in place by the volumetric method was determined by three different approaches. In addition, a technique to be followed in calculating the volumetric original oil in place for the First Eocene reservoir is outlined to overcome the complex behaviour of aquifer salinity. The change in the produced water salinity of the First Eocene reservoir with time was studied and proved that water is dumping from an upper water bearing zone into First Eocene reservoir. Upper water dumping, which apparently has supported the reservoir pressure, was confirmed to occur behind casing in many deeper wells penetrating the First Eocene reservoir by the analysis of their temperature and noise logs.

Response of Alum Rock springs to the October 30, 2007 Alum Rock earthquake and implications for the origin of increased discharge after earthquake  

SciTech Connect

The origin of increased stream flow and spring discharge following earthquakes have been the subject of controversy, in large part because there are many models to explain observations and few measurements suitable for distinguishing between hypotheses. On October 30, 2007 a magnitude 5.5 earthquake occurred near the Alum Rock springs, California, USA. Within a day we documented a several-fold increase in discharge. Over the following year, we have monitored a gradual return towards pre-earthquake properties, but for the largest springs there appears to be a permanent increase in the steady discharge at all the springs. The Alum Rock springs discharge waters that represent a mixture between modern ('shallow') meteoric water and old ('deep') connate waters expelled by regional transpression. After the earthquake, the increased discharge at the largest springs was accompanied by a small decrease in the fraction of connate water in the spring discharge. Combined with the rapid response, this implies that the increased discharge has a shallow origin. Increased discharge at these springs occurs for earthquakes that cause static volumetric expansion and those that cause contraction, supporting models in which dynamic strains are responsible for the subsurface changes that cause flow to increase. We show that models in which the permeability of the fracture system feeding the springs increases after the earthquake are in general consistent with the changes in discharge. The response of these springs to another earthquake will provide critical constraints on the changes that occur in the subsurface.

Deposition and diagenesis of a cratonic Silurian platform reef, Pipe Creek Jr. , Indiana  

SciTech Connect

Petrographic and geochemical characteristics of the Pipe Creek Jr. paragenesis record the stratigraphic and burial evolution of the cratonic Silurian platform of Indiana during Late Silurian to Pennsylvanian. A variety of several diagenetic fluids acting over geological time affected the reef. The paragenetic sequence is as follows: (1) precipitation of turbid, fibrous, blotchy cathodoluminescent (CL) cement; (2) dolomitization of mud-rich facies; (3) precipitation of clear, zoned CL equant calcite cements; (4) fracturing and karst formation, partially filled by geopetal silt and sandstone; (5) precipitation of clear, dull CL, ferroan to nonferroan equant calcite cement, ferroan dolomite overgrowth and equant dolomite cement in moldic porosity, caves and fractures; (6) microdissolution and hydrocarbon emplacement; and (7) stylolitization. Carbonate grew and fibrous cements precipitated in an open marine environment. During Late Silurian an increasingly restricted environment stopped reef growth and dolomite replaced mud-rich faces. The reefs were then subaerially exposed and two meteoric cement sequences, non-luminescent to bright luminescent, precipitated prior to Mid-Devonian fracture-controlled karsting. Caves and fractures crosscut former cement stages and were filled by sandstones. Later, the platform was buried by the late Mid-Devonian organic-rich New Albany Shale, and clear, dull CL calcite cement and ferroan dolomite precipitated. Hydrocarbon migration postdates all cements and created minor moldic porosity and predates stylolitization.

Geothermal potential on Kirtland Air Force Base lands, Bernalillo County, New Mexico  

SciTech Connect

Extensive sampling and geochemical analysis of groundwater in and near the base disclosed no significant geothermal parameters. However, structural conditions and current hydrologic regimes strongly suggest that thermal waters would be masked by near surface, low temperature meteoric water originating as rain and snowfall in the nearby mountains. Controlled source audio-magnetotelluric (CSAMT) electromagnetic techniques, refraction seismic experiments, and gravity traverses were utilized on the base. These, together with published geohysical information that presents evidence for a shallow magma body beneath the Albuquerque Basin; favorable terrestrial heat flow, water chemistry, and shallow temperature gradient holes on the nearby mesa west of the Rio Grande; interpretation of regional gravity data; and geological data from nearby deep wells tend to confirm structural, stratigraphic, and hydrologic conditions favorable for developing an extensive intermediate to high-temperature hydrothermal regime on portions of Kirtland AFB lands where intensive land use occurs. Two possible exploration and development scenarios are presented. One involves drilling a well to a depth of 3000 to 5000 ft (914 to 1524 m) to test the possibility of encountering higher than normal water temperatures on the basinward side of the faults underlying the travertine deposits. The other is to conduct limited reflection seismograph surveys in defined areas on the base to determine the depth to basement (granite) and thickness of the overyling, unconfined, water filled, relatively unconsolidated sand and gravel aquifer.

Radiological assessment of the consequences of the disposal of high-level radioactive waste in subseabed sediments  

SciTech Connect

The radiological assessment of the seabed option consists in estimating the detriment to man and to the environment that could result from the disposal of high-level waste (HLW) within the seabed sediments in deep oceans. The assessment is made for the high-level waste (vitrified glass) produced by the reprocessing of 10/sup 5/ tons of heavy metal from spent fuel, which represents the amount of waste generated by 3333 reactor-yr of 900-MW(electric) reactors, i.e., 3000 GW(electric) x yr. The disposal option considered is to use 14,667 steel penetrators, each of them containing five canisters of HLW glass (0.15 m/sup 3/ each). These penetrators would reach a depth of 50 m in the sediments and would be placed at an average distance of 180 m from each other, requiring a disposal area on the order of 22 x 22 km. Two such potential disposal areas in the Atlantic Ocean were studied, Great Meteor East (GME) and South Nares Abyssal Plains (SNAP). A special ship design is proposed to minimize transportation accidents. Approximately 100 shipments would be necessary to dispose of the proposed amount of waste. The results of this radiological assessment seem to show that the disposal of HLW in subseabed sediments is radiologically a very acceptable option.

Methanol's transformation to commodity status stretches supply  

SciTech Connect

Methanol is undergoing a renaissance. Beginning in the US in the fourth quarter of 1993, methanol has seen a transformation from a low-growth, low-priced, overly abundant commodity chemical into a high-demand, undersupplied, cost-price driven product. As the economic recovery has spread to the rest of the world, methanol demand has dramatically increased. this meteoric rise has been further sparked in the US by increased use of methanol as an ingredient in gasoline oxygenates required by the federal government. Increased demand has led to the consolidation of producers, a scramble to reopen existing capacity, addition of capacity via product conversion, and plans for various future capacity expansions. Methanol fits alongside the other long-standing, major organic commodity chemicals-ethylbenzene, ethylene, ethylene dichloride, formaldehyde, propylene, styrene, terephthalic acid, and vinyl chloride. Methanol also serves both as a building block for many other chemicals--formaldehyde, acetic acid, and terephthalic acid--and as a solvent for many industrial uses.

Geologic and hydrologic controls on coalbed methane producibility, Williams Fork Formation, Piceance Basin, Colorado  

SciTech Connect

Structural and depositional setting, coal rank, gas content, permeability, hydrodynamics, and reservoir heterogeneity control the producibility of coalbed methane in the Piceance Basin. The coal-rich Upper Cretaceous, Williams Fork Formation is genetically defined and regionally correlated to the genetic sequences in the Sand Wash Basin, to the north. Net coal is thickest in north-south oriented belts which accumulated on a coastal plain, behind west-east prograding shoreline sequences.

Coalbed methane resource potential of the Piceance Basin, northwestern Colorado  

SciTech Connect

As predicted, from an evolving coalbed methane producibility model, prolific coalbed methane production is precluded in the Piceance Basin by the absence of coal bed reservoir continuity and dynamic ground-water flow. The best potential for production may lie at the transition zone from hydropressure to hydrocarbon overpressure and/or in conventional traps basinward of where outcrop and subsurface coals are in good reservoir and hydraulic communication. Geologic and hydrologic synergy among tectonic and structural setting, depositional systems and coal distribution, coal rank, gas content, permeability and hydrodynamics are the controls that determine the coalbed methane resource potential of the Piceance Basin. Within the coal-bearing Upper Cretaceous Williams Fork Formation, the prime coalbed methane target, reservoir heterogeneity and thrust faults cause coal beds along the Grand Hogback and in the subsurface to be in modest to poor reservoir and hydraulic communication, restricting meteoric ground water recharge and basinward flow. Total subsurface coalbed methane resources are still estimated to be approximately 99 Tcf (3.09 Tm{sup 3}), although coalbed methane resource estimates range between 80 (2.49 Tm{sup 3}) and 136 Tcf (4.24 Tm{sup 3}), depending on the calculation method used. To explore for high gas contents or fully gas-saturated coals and consequent high productivity in the Piceance Basin, improved geologic and completion technologies including exploration and development for migrated conventionally and hydrodynamically trapped gases, in-situ generated secondary biogenic gases, and solution gases will be required.

Geologic and hydrologic controls on coalbed methane producibility, Williams Fork Formation, Piceance Basin, Colorado  

SciTech Connect

Structural and depositional setting, coal rank, gas content, permeability, hydrodynamics, and reservoir heterogeneity control the producibility of coalbed methane in the Piceance Basin. The coal-rich Upper Cretaceous, Williams Fork Formation is genetically defined and regionally correlated to the genetic sequences in the Sand Wash Basin, to the north. Net coal is thickest in north-south oriented belts which accumulated on a coastal plain, behind west-east prograding shoreline sequences. Face cleats of Late Cretaceous age strike E-NE and W-NW in the southern and northern parts of the basin, respectively, normal to the Grand Hogback thrust front. Parallelism between face-cleat strike and present-day maximum horizontal stresses may enhance or inhibit coal permeability in the north and south, respectively. Geopressure and hydropressure are both present in the basin with regional hydrocarbon overpressure dominant in the central part of the basin and hydropressure limited to the basin margins. The most productive gas wells in the basin are associated with structural terraces, anticlines, and/or correspond to Cameo-Wheeler-Fairfield coal-sandstone development, reflecting basement detached thrust-faulting, fracture-enhanced permeability, and reservoir heterogeneity.

Seismo-ionospheric effects associated with 'Chelyabinsk' meteorite during the first 25 minutes after its fall  

E-Print Network (OSTI)

This paper presents the properties of ionospheric irregularities elongated with Earth magnetic field during the first 25 minutes after the fall of the meteorite 'Chelyabinsk' experimentally observed with EKB radar of Russian segment of the SuperDARN. It is shown that 40 minutes before meteor fall the EKB radar started to observe powerful scattering from irregularities elongated with the Earth magnetic field in the F-layer. Scattering was observed for 80 minutes and stopped 40 minutes after the meteorite fall. During 9-15 minutes after the meteorite fall at ranges 400-1200 km from the explosion site a changes were observed in the spectral and amplitude characteristics of the scattered signal. This features were the sharp increase in the Doppler frequency shift of the scattered signal corresponding to the Doppler velocities about 600 m/s and the sharp increase of the scattered signal amplitude. This allows us to conclude that we detected the growth of small-scale ionospheric irregularities elongated with the Ea...

Crustal structure of northern Gran Canaria, Canary Islands, deduced from active seismic tomography  

Science Journals Connector (OSTI)

Seismic P-wave travel times collected during METEOR cruise M24 are inverted to derive a three-dimensional model of the P-wave velocity structure of the northern part of Gran Canaria, Canary Islands. The data consist of 6689 P-wave travel times from 1487 offshore air-gun shots which were recorded by both land-based seismometers and ocean bottom hydrophones. The crustal structure is well imaged by the data set as demonstrated by analysis of the resolution and tests with synthetic data. The volcanic island is characterized by generally high P-wave velocities (>5.5 km/s) and a heterogeneous structure with large lateral velocity variations. High P-wave velocities are found around the centers of the Miocene shield volcanoes in the vicinity of Agüimes, San Nicolas, and Agaete as well as the center of the Pliocene Roque Nublo volcano. The velocity structure suggests a high percentage of dense intrusive rocks. Some of the intrusive rocks were emplaced during the eruption of >1000 km3 of Miocene felsic magmas following the basaltic shield phase. The velocity structure beneath La Isleta peninsula and its submarine continuation is interpreted as a volcanic rift zone with abundant dikes. The velocities decrease to Gran Canaria is found at a depth of ?15 km. The structure of Gran Canaria and the adjacent ocean basin is thought to be the result of a diffuse mantle upwelling under a slowly moving plate.

Pellet Fueling Technology Development Leading to Efficient Fueling of ITER Burning Plasmas  

SciTech Connect

Pellet injection is the primary fueling technique planned for central fueling of the ITER burning plasma, which is a requirement for achieving high fusion gain. Injection of pellets from the inner wall has been shown on present day tokamaks to provide efficient fueling and is planned for use on ITER [1,2]. Significant development of pellet fueling technology has occurred as a result of the ITER R&D process. Extrusion rates with batch extruders have reached more than 1/2 of the ITER design specification of 1.3 cm3/s [3] and the ability to fuel efficiently from the inner wall by injecting through curved guide tubes has been demonstrated on several fusion devices. Modeling of the fueling deposition from inner wall pellet injection has been done using the Parks et al. ExB drift model [4] shows that inside launched pellets of 3mm size and speeds of 300 m/s have the capability to fuel well inside the separatrix. Gas fueling on the other hand is calculated to have very poor fueling efficiency due to the high density and wide scrape off layer compared to current machines. Isotopically mixed D/T pellets can provide efficient tritium fueling that will minimize tritium wall loading when compared to gas puffing of tritium. In addition, the use of pellets as an ELM trigger has been demonstrated and continues to be investigated as an ELM mitigation technique. During the ITER CDA and EDA the U.S. was responsible for ITER fueling system design and R&D and is in good position to resume this role for the ITER pellet fueling system. Currently the performance of the ITER guide tube design is under investigation. A mockup is being built that will allow tests with different pellet sizes and repetition rates. The results of these tests and their implication for fueling efficiency and central fueling will be discussed. The ITER pellet injection technology developments to date, specified requirements, and remaining development issues will be presented along with a plan to reach the design goal in time for employment on ITER.

Formation waters from Mississippian-Pennsylvanian reservoirs, Illinois basin, USA: Chemical and isotopic constraints on evolution and migration  

SciTech Connect

We have analyzed a suite of seventy-four formation-water samples from Mississippian and Pennsylvanian carbonate and siliciclastic strata in the Illinois basin for major, minor, and trace element concentrations and for strontium isotopic composition. A subset of these samples was also analyzed for boron isotopic composition. Data are used to interpret origin of salinity and chemical and Sr isotopic evolution of the brines and in comparison with a similar data set from an earlier study of basin formation waters from Silurian-Devonian reservoirs. Systematics of Cl-Br-Na show that present Mississippian-Pennsylvanian brine salinity can be explained by a combination of subaerial seawater evaporation short of halite saturation and subsurface dissolution of halite from an evaporite zone in the middle Mississippian St. Louis Limestone, along with extensive dilution by mixing with meteoric waters. Additional diagenetic modifications in the subsurface interpreted from cation/Br ratios include K depletion through interaction with clay minerals, Ca enrichment, and Mg depletion by dolomitization, and Sr enrichment through CaCO[sub 3] recrystallization and dolomitization. Ste. Genevieve Limestone (middle Mississippian) formation waters show [sup 87]Sr/[sup 86]Sr ratios in the range 0.70782-0.70900, whereas waters from the siliciclastic reservoirs are in the rante 0.70900-0.71052. Inverse correlations between [sup 87]Sr/[sup 86]Sr and B,Li, and Mg concentrations suggest that the brines acquired radiogenic [sup 87]Sr through interaction with siliciclastic minerals. Completely unsystematic relations between [sup 87]Fr/[sup 86]Sr and 1/Sr are observed; Sr concentrations in Ste. Genevieve and Aux Vases (middle Mississippian) waters appear to be buffered by equilibrium with respect to SrSo[sub 4]. These formation waters are distinguished from Silurian-Devonian brines in the basin by elevated Cl/Br and Na/Br ratios and by unsystematic Sr isotope relationships.

Origin and geochemical evolution of the Michigan basin brine  

SciTech Connect

Chemical and isotopic data were collected on 126 oil field brine samples and were used to investigate the origin and geochemical evolution of water in 8 geologic formations in the Michigan basin. Two groups of brine are found in the basin, the Na-Ca-Cl brine in the upper Devonian formations, and Ca-Na-Cl brine from the lower Devonian and Silurian aged formations. Water in the upper Devonian Berea, Traverse, and Dundee formations originated from seawater concentrated into halite facies. This brine evolved by halite precipitation, dolomitization, aluminosilicate reactions, and the removal of SO{sub 4} by bacterial action or by CaSO{sub 4} precipitation. The stable isotopic composition (D, O) is thought to represent dilution of evapo-concentrated seawater by meteoric water. Water in the lower Devonian Richfield, Detroit River Group, and Niagara-Salina formations is very saline Ca-Na-Cl brine. Cl/Br suggest it originated from seawater concentrated through the halite and into the MgSO{sub 4} salt facies, with an origin linked to the Silurian and Devonian salt deposits. Dolomitization and halite precipitation increased the Ca/Na, aluminosilicate reactions removed K, and bacterial action or CaSO{sub 4} precipitation removed SO{sub 4} from this brine. Water chemistry in the Ordovician Trenton-Black River formations indicates dilution of evapo-concentrated seawater by fresh or seawater. Possible saline end-members include Ordovician seawater, present-day upper Devonian brine, or Ca-Cl brine from the deeper areas in the basin.

Petrography and geochemistry of the Artesia Group, Palo Duro Basin, Texas Panhandle: Final report  

SciTech Connect

The Artesia Group of the Texas Panhandle is an evaporite red-bed sequence which has been intensely altered by interaction of evaporites with ground water. Comparison of the upper, most altered part of the sequence with the lower, least altered part allows identification of the diagenetic sequence. The least altered lower part of the Artesia Group includes anhydrite beds, anhydritic halite, mudstone-halite mixtures, mudstone, claystone, siltstone, and sandstone. Diagenetic processes include cementation by halite, replacement of gypsum by anhydrite and minor polyhalite, and minor replacement of halite by dolomite and anhydrite. Halite is present throughout the lower part of the Artesia Group as bedded halite, as isolated halite crystals and veins, and as halite cement in clastic beds. The altered interval in the upper part of the Artesia Group is characterized by mudstone-anhydrite-dolomite breccias, thin, wavy laminae of anhydrite and dolomite, and abundant fractures filled with fibrous anhydrite and gypsum in mudstone, claystone, siltstone, and thin anhydrite beds. Halite is absent, and removal of halite is interpreted as the principal cause of the alteration, either directly, by dissolution and collapse, or indirectly, by increasing porosity and allowing increased ground-water penetration. At the top of the Artesia Group, anhydrite has been hydrated to gypsum, and minor amounts of gypsum have been replaced by calcite. The geochemistry of preserved halite in the lower part of the Artesia Group shows that meteoric waters have been included in halite and that halite has been recycled by dissolution and reprecipitation. The occurrence of this type of alteration might indicate that the halite of the Artesia Group was invaded by waters from the overlying aquifers. However, the stratigraphic and textural relationships in the halite indicate that the alteration reflects continental influences in the clastic-dominated depositional environment. 32 refs., 45 figs., 1 tab.

Diagenesis of Eolian and fluvial feldspathic sandstones, Norphlet formation (upper Jurassic), Rankin County, Mississippi, and Mobile County, Alabama  

SciTech Connect

Norphlet sandstones in seven cores from Mississippi and Alabama are arkoses and subarkoses deposited in eolian-dune, interdune, and fluvial environments. Similar to the deeply buried (> 5 km) Tertiary feldspathic sandstones of the Gulf basin, all detrital plagioclase that survived dissolution has been albitized. Fluvial red sandstone lost all initial porosity by the introduction of preburial pedogenic calcite and compaction. Initial porosity of eolian sands was reduced by compaction to an average of 29%; and later by cementation by quartz, carbonates, anhydrite, halite, K-feldspar, and illite. Quartz and anhydrite cements precipitated between 90/sup 0/ and 100/sup 0/C (approximately 2.3 km deep), carbonates and halite cements formed below 120/sup 0/C (< 3 km), and late-stage illite cement formed between 130/sup 0/ and 150/sup 0/C (4-5 km deep). Cements are patchy, and some, especially quartz and anhydrite, are texture-selective, being more abundant in coarser laminae. Secondary porosity, which makes up approximately half the porosity in thin sections, formed by dissolution of detrital grains (feldspar, rock fragments) and cements (anhydrite, carbonate, halite). Reservoir bitumen records an early phase of oil entrapment. Reservoir quality is influenced by the abundance of reservoir bitumen and thread-like illite, both of which bridge pores. Isotopic data suggest that during the first 30 to 40 m.y. of burial, subsurface diagenesis of the Norphlet Formation was dominated by deep-circulating, hot, meteoric water. This phenomenon may be characteristic of the early diagenetic history of rifted basins. 10 figures, 5 tables.

Origin, distribution, and movement of brine in the Permian Basin (U. S. A. ). A model for displacement of connate brine  

SciTech Connect

Na-Cl, halite Ca-Cl, and gypsum Ca-Cl brines with salinities from 45 to >300 g/L are identified and mapped in four hydrostratigraphic units in the Permian Basin area beneath western Texas and Oklahoma and eastern New Mexico, providing spatial and lithologic constraints on the interpretation of the origin and movement of brine. Na-Cl brine is derived from meteoric water as young as 5-10 Ma that dissolved anhydrite and halite, whereas Ca-Cl brine is interpreted to be ancient, modified-connate Permian brine that now is mixing with, and being displaced by, the Na-Cl brine. Displacement fronts appear as broad mixing zones with no significant salinity gradients. Evolution of Ca-Cl brine composition from ideal evaporated sea water is attributed to dolomitization and syndepositional recycling of halite and bittern salts by intermittent influx of fresh water and sea water. Halite Ca-Cl brine in the evaporite section in the northern part of the basin differs from gypsum Ca-Cl brine in the south-central part in salinity and Na/Cl ratio and reflects segregation between halite- and gypsum-precipitating lagoons during the Permian. Ca-Cl brine moved downward through the evaporite section into the underlying Lower Permian and Pennsylvanian marine section that is now the deep-basin brine aquifer, mixing there with pre-existing sea water. Buoyancy-driven convection of brine dominated local flow for most of basin history, with regional advection governed by topographically related forces dominant only for the past 5 to 10 Ma. 71 refs., 11 figs.

Geothermal energy resources in Trans-Pecos Texas - characteristics and potential for development  

SciTech Connect

Convective geothermal systems in Trans-pecos Texas, and Chihuahua and Coahuila, Mexico, are potential energy resources. The geothermal systems, which lie along a narrow belt near the Rio Grand River, are characterized by hot springs and shallow hot wells located along normal faults. The hot water is meteoric water that has circulated to depths of 2-3 km (1-2 mi), been heated, and risen to the surface through fractures along fault zones. The heat source is the Earth's normal thermal gradient, which as high as 40/sup 0/C/km (202/sup 0/F/100 ft); no young magma bodies are involved. Maximum measured temperatures are 90/sup 0/C (194/sup 0/F) at a hot spring in Chihuahua, about 80/sup 0/C (176/sup 0/F) in 2 well in the Sierra Vieja, and about 75/sup 0/C (167/sup 0/F) in several wells east of El Paso. Many springs have temperature in the range 35-50/sup 0/C (95-122/sup 0/F). Maximum subsurface temperatures estimated from chemical geothermometers are 100-160/sup 0/C (212-320/sup 0/F); most are considerably lower. Chemical constraints on use should be negligible except for the El Paso-area waters, which have moderately high dissolved solids (10,000 mg/L). Hydrologic data to evaluate possible production rates are generally sparse. None of the waters are hot enough to generate electricity by currently available technology. The highest temperature waters could be used for industrial or space heating, but, except for the area near El Paso, they are too far from population centers.

Trace element and isotope geochemistry of geothermal fluids, East Rift Zone, Kilauea, Hawaii  

SciTech Connect

A research program has been undertaken in an effort to better characterize the composition and the precipitation characteristic of the geothermal fluids produced by the HGP-A geothermal well located on the Kilauea East Rift Zone on the Island of Hawaii. The results of these studies have shown that the chemical composition of the fluids changed over the production life of the well and that the fluids produced were the result of mixing of at least two, and possibly three, source fluids. These source fluids were recognized as: a sea water composition modified by high temperature water-rock reactions; meteoric recharge; and a hydrothermal fluid that had been equilibrated with high temperature reservoir rocks and magmatic volatiles. Although the major alkali and halide elements show clearly increasing trends with time, only a few of the trace transition metals show a similar trend. The rare earth elements, were typically found at low concentrations and appeared to be highly variable with time. Studies of the precipitation characteristics of silica showed that amorphous silica deposition rates were highly sensitive to fluid pH and that increases in fluid pH above about 8.5 could flocculate more than 80% of the suspended colloidal silica in excess of its solubility. Addition of transition metal salts were also found to enhance the recovery fractions of silica from solution. The amorphous silica precipitate was also found to strongly scavenge the alkaline earth and transition metal ions naturally present in the brines; mild acid treatments were shown to be capable of removing substantial fractions of the scavenged metals from the silica flocs yielding a moderately pure gelatinous by-product. Further work on the silica precipitation process is recommended to improve our ability to control silica scaling from high temperature geothermal fluids or to recover a marketable silica by-product from these fluids prior to reinjection.

Silver Peak Innovative Exploration Project (Ram Power Inc.)  

SciTech Connect

Data generated from the Silver Peak Innovative Exploration Project, in Esmeralda County, Nevada, encompasses a “deep-circulation (amagmatic)” meteoric-geothermal system circulating beneath basin-fill sediments locally blanketed with travertine in western Clayton Valley (lithium-rich brines from which have been mined for several decades). Spring- and shallow-borehole thermal-water geochemistry and geothermometry suggest that a Silver Peak geothermal reservoir is very likely to attain the temperature range 260- 300oF (~125-150oC), and may reach 300-340oF (~150-170oC) or higher (GeothermEx, Inc., 2006). Results of detailed geologic mapping, structural analysis, and conceptual modeling of the prospect (1) support the GeothermEx (op. cit.) assertion that the Silver Peak prospect has good potential for geothermal-power production; and (2) provide a theoretical geologic framework for further exploration and development of the resource. The Silver Peak prospect is situated in the transtensional (regional shearing coupled with extension) Walker Lane structural belt, and squarely within the late Miocene to Pliocene (11 Ma to ~5 Ma) Silver Peak-Lone Mountain metamorphic core complex (SPCC), a feature that accommodated initial displacement transfer between major right-lateral strike- slip fault zones on opposite sides of the Walker Lane. The SPCC consists essentially of a ductiley-deformed lower plate, or “core,” of Proterozoic metamorphic tectonites and tectonized Mesozoic granitoids separated by a regionally extensive, low-angle detachment fault from an upper plate of severely stretched and fractured structural slices of brittle, Proterozoic to Miocene-age lithologies. From a geothermal perspective, the detachment fault itself and some of the upper-plate structural sheets could function as important, if secondary, subhorizontal thermal-fluid aquifers in a Silver Peak hydrothermal system.

Low-to-moderate temperature geothermal resource assessment for Nevada: Area specific studies, final report for the period June 1, 1980-August 30, 1981  

SciTech Connect

The Hawthorne study area is located in Mineral County, Nevada and surrounds the municipality of the same name. It encompasses an area of approximately 310 sq. km (120 sq. mi), and most of the land belongs to the US Army Ammunition Plant. The energy needs of the military combined with those of the area population (over 5,000 residents) are substantial. The area is classified as having a high potential for direct applications using the evaluation scheme described in Trexler and others (1979). A variety of scientific techniques was employed during area-wide resource assessment. General geologic studies demonstrate the lithologic diversity in the area; these studies also indicate possible sources for dissolved fluid constituents. Geophysical investigations include aeromagnetic and gravity surveys which aid in defining the nature of regional, and to a lesser extent, local variations in subsurface configurations. Surface and near-surface structural features are determined using various types of photo imagery including low sun-angle photography. An extensive shallow depth temperature probe survey indicates two zones of elevated temperature on opposite sides of the Walker Lake basin. Temperature-depth profiles from several wells in the study area indicate significant thermal fluid-bearing aquifers. Fluid chemical studies suggest a wide spatial distribution for the resource, and also suggest a meteoric recharge source in the Wassuk Range. Finally, a soil-mercury survey was not a useful technique in this study area. Two test holes were drilled to conclude the area resource assessment, and thermal fluids were encountered in both wells. The western well has measured temperatures as high as 90 C (194 F) within 150 meters (500 ft) of the surface. Temperature profiles in this well indicate a negative temperature gradient below 180 meters (590 ft). The eastern hole had a bottom hole temperature of 61 C (142 F) at a depth of only 120 meters (395 ft). A positive gradient is observed to a total depth in the well.

Application of seismic tomographic techniques in the investigation of geothermal systems  

SciTech Connect

The utility of microearthquake data for characterizing the Northwest Geysers geothermal field and the Long Valley Caldera (LVC) was investigated. Three-dimensional (3-D) P- and S-wave seismic velocity models were estimated for the Coldwater Creek Steam Field (CCSF) in the Northwest Geysers region. Hypocenters relocated using these 3-D models appear to be associated with the steam producing zone, with a deeper cluster of hypocenters beneath an active injection well. Spatial and temporal patterns of seismicity exhibit strong correlation with geothermal exploitation. A 3-D differential attenuation model was also developed for the CCSF from spectral ratios corrected for strong site effects. High-velocity anomalies and low attenuation in the near surface correspond to Franciscan metagraywacke and greenstone units. Microearthquakes recorded at seismographic stations located near the metagraywacke unit exhibit high corner frequencies. Low-velocity anomalies and higher attenuation in the near surface are associated with sections of Franciscan melange. Near-surface high attenuation and high Vp/Vs are interpreted to indicate liquid-saturated regions affected by meteoric recharge. High attenuation and low Vp/Vs marks the steam producing zone, suggesting undersaturation of the reservoir rocks. The extent of the high attenuation and low Vp/Vs anomalies suggest that the CCSF steam reservoir may extend northwestward beyond the known producing zone. This study concludes that microearthquake monitoring may be useful as an active reservoir management tool. Seismic velocity and attenuation structures as well as the distribution of microearthquake activity can be used to identify and delineate the geothermal reservoir, while temporal variations in these quantities would be useful in tracking changes during exploitation.

Fluid flow in the resurgent dome of Long Valley Caldera: implications from thermal data and deep electrical sounding  

Science Journals Connector (OSTI)

Temperatures of 100°C are measured at 3 km depth in a well located on the resurgent dome in the center of Long Valley Caldera, California, despite an assumed >800°C magma chamber at 6–8 km depth. Local downflow of cold meteoric water as a process for cooling the resurgent dome is ruled out by a Peclét-number analysis of temperature logs. These analyses reveal zones with fluid circulation at the upper and lower boundaries of the Bishop Tuff, and an upflow zone in the metasedimentary rocks. Vertical Darcy velocities range from 10 to 70 cm a?1. A 21-km-long geoelectrical profile across the caldera provides resistivity values to the order of 100 to >103 ?m down to a depth of 6 km, as well as variations of self-potential. Interpretation of the electrical data with respect to hydrothermal fluid movement confirms that there is no downflow beneath the resurgent dome. To explain the unexpectedly low temperatures in the resurgent dome, we challenge the common view that the caldera as a whole is a regime of high temperatures and the resurgent dome is a local cold anomaly. Instead, we suggest that the caldera was cooled to normal thermal conditions by vigorous hydrothermal activity in the past, and that a present-day hot water flow system is responsible for local hot anomalies, such as Hot Creek and the area of the Casa Diablo geothermal power plant. The source of hot water has been associated with recent shallow intrusions into the West Moat. The focus of planning for future power plants should be to locate this present-day flow system instead of relying on heat from the old magma chamber.

Ca, Sr, O and D isotope approach to defining the chemical evolution of hydrothermal fluids: Example from Long Valley, CA, USA  

Science Journals Connector (OSTI)

Abstract We present chemical and isotopic data for fluids, minerals and rocks from the Long Valley meteoric-hydrothermal system. The samples encompass the presumed hydrothermal upwelling zone in the west moat of the caldera, the Casa Diablo geothermal field, and a series of wells defining a nearly linear, ?16 km long, west-to-east trend along the likely fluid flow path. Fluid samples were analyzed for the isotopes of water, Sr, and Ca, the concentrations of major cations and anions, alkalinity, and total CO2. Water isotope data conform to trends documented in earlier studies, interpreted as indicating a single hydrothermal fluid mixing with local groundwater. Sr isotopes show subtle changes along the flow path, which requires rapid fluid flow and minimal reaction between the channelized fluids and the wallrocks. Sr and O isotopes are used to calculate fracture spacing using a dual porosity model. Calculated fracture spacing and temperature data for hydrothermal fluids indicate the system is (approximately) at steady-state. Correlated variations among total CO2, and the concentration and isotopic composition of Ca suggest progressive fluid degassing (loss of CO2), which drives calcite precipitation as the fluid flows west-to-east and cools. The shifts in Ca isotopes require that calcite precipitated at temperatures of 150–180 °C is fractionated by ca. ?0.3‰ to ?0.5‰ relative to aqueous species. Our data are the first evidence that Ca isotopes undergo kinetic fractionation at high temperatures (>100 °C) and can be used to trace calcite precipitation along hydrothermal fluid flow paths.

Hydrogeological influences on petroleum accumulations in the Arabian Gulf  

SciTech Connect

The stratigraphic and topographic conditions in the Arabian Gulf are appropriate for the instigation and maintenance of an active hydrodynamic regime. The setting is that of a gentle basin surrounded by topographic highs. The central Arabian highlands to the west-southwest, the Tarus-Zagros mountains to the north, and the Oman mountains to the east rim the structural low occupied by the Gulf. Elevations in these areas reach maximum values of approximately 1000 meters. Paleozoic through Cenozoic strata stretch continuously across the basin, are relatively unfaulted, and outcrop in the topographic highs. Such a setting is propitious for a regional hydrodynamic system with meteoric recharge in the topographic highs and discharge in the middle of the Gulf. The prolific oil and gas accumulations of this region would be subject to influence by these hydrodynamic processes. The existence of such a hydrodynamic regime is documented by a variety of evidence, including potentiometric data, water salinity measurements, and observed tilts in oil-water contacts. Potentiometric data for several Tertiary and Cretaceous units on the Arabian platform, in the Gulf, and in Iraq show a pattern of consistently decreasing potential from topographic highs to lows. Water salinities show a consistent, but inverse, variation with the potentiometric data. Tilted oil-water contacts in Cretaceous and Jurassic reservoirs are observed in several fields of the Gulf region. The direction and magnitude of the observed tilts are consistent with the water potential and salinity data, and suggest that petroleum accumulations are being influenced by a regional hydrodynamic drive. Basin modelling is used to simulate petroleum generation and migration scenarios, and to integrate these histories with the structural evolution of the Gulf. The integrated modelling study illustrates the influence of hydrodynamic processes on the distribution of petroleum accumulations.

The southern Bonaparte Gulf, northwest Australia - New exploration plays  

SciTech Connect

Integration of regional exploration data with new basin model concepts has generated new exploration plays in the offshore area defined as the Southern Bonaparte Gulf. This area represents a unique hydrocarbon habitat significantly different from adjacent areas. Early exploration (seven wells), targeting structural highs, encountered numerous hydrocarbon shows. Of most recent significance, Turtle-1 (1984) targeted a midbasin MS-I high recovering degraded oils in the MS-III section. Turtle-2 (1989) tested an additional 320-m-thick, MS-II onlap, encountering within fractured intervals significant oil and gas influx accompanied by massive lost circulation. Significant live oil (nondegraded) was produced on test despite formation damage inflicted during the 14-day well control period. Within the MS-III section thin incompetent seals and meteoric waters have resulted in small, degraded, low-GOR (gas/oil ratio) oil accumulations. In contrast the MS-II section has competent seals and exhibits high-GOR live oil. In consequence, given suitable models for porosity development, MS-II is highly prospective, indicating new exploratory plays: (1) MS-II fractured, stratigraphic pinch-outs flanking MS-I structures, (2) MS-II stacked turbidites and basin floor fans deposited in salt withdrawal subbasins, (3) MS-II carbonate banks within the subbasin's marginal carbonate complexes, (4) MS-I reefs localized over early salt structures and onlapped by MS-II sediments, and (5) MS-II structural and stratigraphic traps associated with diapiric salt. By virtue of the stratigraphic and structural relationship of MS-U sediments, generally onlapping the flanks of the structural highs originally targeted, these new plays have not been tested in optimal locations. A new phase of exploration specifically targeted at these plays is planned.

Subsurface temperature distributions in south Texas  

SciTech Connect

Isothermal surfaces and temperature gradients confirm the presence of anomalously high geothermal gradients within south Texas. The authors have analyzed over 2,200 oil and gas well logs and compiled more than 5,200 corrected bottom-hole temperature measurements. The data show that temperature gradients often steepen from around 30{degree}C/km up to 60{degree}C/km near the top of geopressure (> 15.8 kPa/m from 1,800 to 3,600 m) through much of the south Texas Gulf Coast. However, the highest gradients coincide with the Wilcox growth-fault zone. Within the Wilcox trend, isotherms indicate that the elevated temperatures become more prominent with depth. Their qualitative analyses indicate that the thermal anomaly is caused by advecting fluids moving upward, along and just coastward of the Wilcox fault zone. In addition, preliminary computer modeling indicates that a pulse or pulses of deep upwelling fluids could create the anomalous temperatures. Petrographic and geochemical data are also consistent with enhanced fluid flux in the zones of elevated temperatures, as are the distributions of hydrocarbon and uranium deposits. Higher temperatures also exist above the top of geopressure along the Wilcox trend, which suggests that fluids are escaping from the geopressured zone via growth faults and perturbing the temperature field in the overlying meteoric regime. Although a few areas of the Vicksburg-Frio growth fault zones have elevated temperature gradients below the top of geopressure, it is still unknown why such a prominent thermal anomaly occurs along the Wilcox trend but not along the Vicksburg and Frio trends.

Post-eruptive alteration of silicic ignimbrites and lavas, Gran Canaria, Canary Islands: Strontium, neodymium, lead, and oxygen isotopic evidence  

SciTech Connect

Isotopic analyses of Miocene comenditic, pantelleritic, and trachyphonolitic ignimbrites and lavas from Gran Canaria, Canary Islands, provide evidence for posteruptive mobility of Rb, Sr, and O. Calculated initial [sup 87]Sr/[sup 86]Sr ratios in whole-rock samples from basaltic lavas and feldspar mineral separates from ignimbrites define a magmatic trend in the stratigraphic section, from ratios of 0.70340 at the base of the Mogan Formation to 0.70305 in the lower Fataga Formation. However, calculated apparent initial [sup 87]Sr/[sup 86]Sr ratios in hydrated vitrophyre and devitrified matrix separates range from 0.7035 to 0.7090. [delta][sup 18]O ratios in basalts and feldspars vary little, from +5.7 to +6.1, yet range from +6.5 to +15.0 in the ignimbrite matrices. In contrast to the Sr and O isotope ratios, Pb and Nd isotope ratios are identical within analytical error in feldspars and their silicic ignimbrite matrices. Sequential leaching experiments and the oxygen data suggest that low-temperature, posteruptive interaction with meteoric water, perhaps containing a small seawater component, has modified Rb and Sr concentrations in the matrices, such that calculated apparent initial [sup 87]Sr/[sup 86]Sr ratios are not those of the magmas when they were erupted. Mobilization of Rb and Sr must occur significantly after eurption. Nd and Pb isotope systems appear to be unaffected by this process. Therefore, [sup 87]Sr/[sup 86]Sr ratios determined by whole rock analysis of silicic rocks from hotspot-type oceanic islands are suspect and should not be incorporated into mantle tracer studies, although analysis of phenocrysts may produce useful data. 40 refs., 5 figs., 3 tabs.

Microbial degradation of sedimentary organic matter associated with shale gas and coalbed methane in eastern Illinois Basin (Indiana), USA  

Science Journals Connector (OSTI)

Molecular biodegradation indices for extracts from five Pennsylvanian coals and six New Albany Shale (Devonian – Mississippian) samples from the eastern part of the Illinois Basin help constrain relationships between the degradation of biomarkers and the generation of coalbed methane and shale gas. Investigation of these gas source rocks of varying thermal maturity from different depths facilitates evaluation of the association of microbial degradation with biogenic gas formation distinct from thermogenic processes. Extensive biodegradation of both aliphatic and aromatic hydrocarbons is observed in the coal extracts, whereas in shale extracts only short-chain (C15–C19) n-alkanes from the shallowest depth appear to be microbially altered with minimal evidence for losses of acyclic isoprenoid alkanes and aromatic hydrocarbons. By contrast, biodegradation of aromatic hydrocarbons, specifically alkylated naphthalenes and phenanthrenes, occurs in coal extracts in concert with losses of n-alkanes attributable to microbial activity. Thus, the progress of hydrocarbon biodegradation in coals differs from the sequence recognized in petroleum where the effects of microbial alteration of aromatic constituents only appear after extensive losses of aliphatic compounds. The extent of hydrocarbon biodegradation in these coals also decreases with depth, as recorded by the ?(nC25–nC30) index (i.e. abundance relative to 17?(H), 21?(H)-hopane) among the aliphatic constituents and several aromatic compounds (methyl-, dimethyl-, and trimethylnaphthalenes, phenanthrene, and trimethyl- and tetramethylphananthrenes). However, the depth variations in the distributions of aliphatic and aromatic hydrocarbons in the shale extracts primarily reflect the effects of thermal maturity rather than biodegradation. Overall, variations in the extent and patterns of biomarker biodegradation among coals and shales likely reflect their distinct microbial consortia that can be attributed to differences in (i) surviving microorganisms and inoculations from meteoric water, (ii) the characteristics of the sedimentary organic matter, especially the preponderance of aromatic constituents in coals, and (iii) the accessibility to that substrate through pores and cleats. These results help constrain the processes involved in biodegradation and controls on its extent, which, in turn, assist in recognizing sites favorable for methanogenesis and improved estimates of biogenic gas resources in the Illinois Basin.

A Non-Proliferating Fuel Cycle: No Enrichment, Reprocessing or Accessible Spent Fuel - 12375  

SciTech Connect

Current fuel cycles offer a number of opportunities for access to plutonium, opportunities to create highly enriched uranium and access highly radioactive wastes to create nuclear weapons and 'dirty' bombs. The non-proliferating fuel cycle however eliminates or reduces such opportunities and access by eliminating the mining, milling and enrichment of uranium. The non-proliferating fuel cycle also reduces the production of plutonium per unit of energy created, eliminates reprocessing and the separation of plutonium from the spent fuel and the creation of a stream of high-level waste. It further simplifies the search for land based deep geologic repositories and interim storage sites for spent fuel in the USA by disposing of the spent fuel in deep sub-seabed sediments after storing the spent fuel at U.S. Navy Nuclear Shipyards that have the space and all of the necessary equipment and security already in place. The non-proliferating fuel cycle also reduces transportation risks by utilizing barges for the collection of spent fuel and transport to the Navy shipyards and specially designed ships to take the spent fuel to designated disposal sites at sea and to dispose of them there in deep sub-seabed sediments. Disposal in the sub-seabed sediments practically eliminates human intrusion. Potential disposal sites include Great Meteor East and Southern Nares Abyssal Plain. Such sites then could easily become international disposal sites since they occur in the open ocean. It also reduces the level of human exposure in case of failure because of the large physical and chemical dilution and the elimination of a major pathway to man-seawater is not potable. Of course, the recovery of uranium from sea water and the disposal of spent fuel in sub-seabed sediments must be proven on an industrial scale. All other technologies are already operating on an industrial scale. If externalities, such as reduced terrorist threats, environmental damage (including embedded emissions), long term care, reduced access to 'dirty' bomb materials, the social and political costs of siting new facilities and the psychological impact of no solution to the nuclear waste problem, were taken into account, the costs would be far lower than those of the present fuel cycle.

Heterogeneous Shallow-Shelf Carbonate Buildups in the Paradox Basin, Utah and Colorado: Targets for Increased Oil Production and Reserves Using Horizontal Drilling Techniques  

SciTech Connect

The Paradox Basin of Utah, Colorado, Arizona, and New Mexico contains nearly 100 small oil fields producing from carbonate buildups within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to 10 wells with primary production ranging from 700,000 to 2,000,000 barrels (111,300-318,000 m{sup 3}) of oil per field and a 15 to 20 percent recovery rate. At least 200 million barrels (31.8 million m{sup 3}) of oil will not be recovered from these small fields because of inefficient recovery practices and undrained heterogeneous reservoirs. Several fields in southeastern Utah and southwestern Colorado are being evaluated as candidates for horizontal drilling and enhanced oil recovery from existing vertical wells based upon geological characterization and reservoir modeling case studies. Geological characterization on a local scale is focused on reservoir heterogeneity, quality, and lateral continuity, as well as possible reservoir compartmentalization, within these fields. This study utilizes representative cores, geophysical logs, and thin sections to characterize and grade each field's potential for drilling horizontal laterals from existing development wells. The results of these studies can be applied to similar fields elsewhere in the Paradox Basin and the Rocky Mountain region, the Michigan and Illinois Basins, and the Midcontinent region. This report covers research activities for the first half of the fourth project year (April 6 through October 5, 2003). The work included (1) analysis of well-test data and oil production from Cherokee and Bug fields, San Juan County, Utah, and (2) diagenetic evaluation of stable isotopes from the upper Ismay and lower Desert Creek zones of the Paradox Formation in the Blanding sub-basin, Utah. Production ''sweet spots'' and potential horizontal drilling candidates were identified for Cherokee and Bug fields. In Cherokee field, the most productive wells are located in the thickest part of the mound facies of the upper Ismay zone, where microporosity is well developed. In Bug field, the most productive wells are located structurally downdip from the updip porosity pinch out in the dolomitized lower Desert Creek zone, where micro-box-work porosity is well developed. Microporosity and micro-box-work porosity have the greatest hydrocarbon storage and flow capacity, and potential horizontal drilling target in these fields. Diagenesis is the main control on the quality of Ismay and Desert Creek reservoirs. Most of the carbonates present within the lower Desert Creek and Ismay have retained a marine-influenced carbon isotope geochemistry throughout marine cementation as well as through post-burial recycling of marine carbonate components during dolomitization, stylolitization, dissolution, and late cementation. Meteoric waters do not appear to have had any effect on the composition of the dolomites in these zones. Light oxygen values obtained from reservoir samples for wells located along the margins or flanks of Bug field may be indicative of exposure to higher temperatures, to fluids depleted in {sup 18}O relative to sea water, or to hypersaline waters during burial diagenesis. The samples from Bug field with the lightest oxygen isotope compositions are from wells that have produced significantly greater amounts of hydrocarbons. There is no significant difference between the oxygen isotope compositions from lower Desert Creek dolomite samples in Bug field and the upper Ismay limestones and dolomites from Cherokee field. Carbon isotopic compositions for samples from Patterson Canyon field can be divided into two populations: isotopically heavier mound cement and isotopically lighter oolite and banded cement. Technology transfer activities consisted of exhibiting a booth display of project materials at the annual national convention of the American Association of Petroleum Geologists, a technical presentation, a core workshop, and publications. The project home page was updated on the Utah Geological Survey Internet web site.

Geology and hydrogeochemistry of the Jungapeo CO2-rich thermal springs, State of Michoacán, Mexico  

Science Journals Connector (OSTI)

We present the first geothermal assessment of the Jungapeo CO2-rich mineral springs, which are located in the eastern part of Michoacán State (central Mexico) at the southern limit of the Trans-Mexican Volcanic Belt. All but one of the > 10 springs occur at the lower contact of the distal olivine-bearing basaltic andesite lavas of the Tuxpan shield, a 0.49- to 0.60-Ma-old cluster of monogenetic scoria cones and lava flows. The Tuxpan shield has a maximum radius of 6 km and was constructed on top of a folded and faulted Cretaceous basement consisting largely of marine limestones, marls, and shales. The mineral waters are characterized by moderate temperatures (28 to 32 °C), mild acidity (pH from 5.5 to 6.5), relatively high discharge rates, effervescence of CO2 gas, clarity at emergence and abundant subsequent precipitation of hydrous iron, silica oxides, and carbonates around pool margins and issuing streamlets. Chemical and isotopic (deuterium, oxygen, and tritium) analyses of water and gas samples obtained during the period 1991–1997 indicate that the springs are largely composed of meteoric water from a local source with relatively short residence times (water ages of 7 to 25 years). Spring waters are chemically characterized by moderate SiO2, Ca + Mg nearly equal to Na + K, high HCO3, moderate to low Cl, low F and SO4, high B, moderate Li, while Br and As are low. In contrast, Fe + Mn is exceptionally high. Thus, the Jungapeo waters cannot be regarded as high-temperature geothermal fluids. Instead, they resemble soda spring waters similar to other low-to-medium temperature soda waters in the world. Gas samples are extremely rich in CO2 with no detectable geothermal H2S or H2 and very low contents of CH4 and NH3, indicating the gases are not derived from a high-temperature resource. Carbon-13 analyses of CO2 show a narrow range (? 6.7‰ and ? 7.2‰) that falls within the range for MORB CO2. Thus, most CO2 seems to originate from the mantle but some CO2 could originate from thermal degradation of organic remains in underlying Cretaceous rocks. 3/4He ratios range from about 2 to 3 Rc/Ra, indicating that a small mantle/magmatic He component is present in the gases. In conclusion, the mineral waters are the surface expression of a low-temperature geothermal system of limited size that originates from the combined effects of a high regional heat flow and (possibly) the remnant heat released from subjacent basaltic andesite magma bodies that constitute the root zone of the Tuxpan shield.

Water Management Strategies for Improved Coalbed Methane Production in the Black Warrior Basin  

SciTech Connect

The modern coalbed methane industry was born in the Black Warrior Basin of Alabama and has to date produced more than 2.6 trillion cubic feet of gas and 1.6 billion barrels of water. The coalbed gas industry in this area is dependent on instream disposal of co-produced water, which ranges from nearly potable sodium-bicarbonate water to hypersaline sodium-chloride water. This study employed diverse analytical methods to characterize water chemistry in light of the regional geologic framework and to evaluate the full range of water management options for the Black Warrior coalbed methane industry. Results reveal strong interrelationships among regional geology, water chemistry, and gas chemistry. Coalbed methane is produced from multiple coal seams in Pennsylvanian-age strata of the Pottsville Coal Interval, in which water chemistry is influenced by a structurally controlled meteoric recharge area along the southeastern margin of the basin. The most important constituents of concern in the produced water include chlorides, ammonia compounds, and organic substances. Regional mapping and statistical analysis indicate that the concentrations of most ionic compounds, metallic substances, and nonmetallic substances correlate with total dissolved solids and chlorides. Gas is effectively produced at pipeline quality, and the only significant impurity is N{sub 2}. Geochemical analysis indicates that the gas is of mixed thermogenic-biogenic origin. Stable isotopic analysis of produced gas and calcite vein fills indicates that widespread late-stage microbial methanogenesis occurred primarily along a CO{sub 2} reduction metabolic pathway. Organic compounds in the produced water appear to have helped sustain microbial communities. Ammonia and ammonium levels increase with total dissolved solids content and appear to have played a role in late-stage microbial methanogenesis and the generation of N{sub 2}. Gas production tends to decline exponentially, whereas water production tends to decline hyperbolically. Hyperbolic decline indicates that water volume is of greatest concern early in the life of a coalbed methane project. Regional mapping indicates that gas production is controlled primarily by the ability to depressurize permeable coal seams that are natively within the steep part of the adsorption isotherm. Water production is greatest within the freshwater intrusion and below thick Cretaceous cover strata and is least in areas of underpressure. Water management strategies include instream disposal, which can be applied effectively in most parts of the basin. Deep disposal may be applicable locally, particularly where high salinity limits the ability to dispose into streams. Artificial wetlands show promise for the management of saline water, especially where the reservoir yield is limited. Beneficial use options include municipal water supply, agricultural use, and industrial use. The water may be of use to an inland shrimp farming industry, which is active around the southwestern coalbed methane fields. The best opportunities for beneficial use are reuse of water by the coalbed methane industry for drilling and hydraulic fracturing. This research has further highlighted opportunities for additional research on treatment efficiency, the origin of nitrogen compounds, organic geochemistry, biogenic gas generation, flow modeling, and computer simulation. Results of this study are being disseminated through a vigorous technology transfer program that includes web resources, numerous presentations to stakeholders, and a variety of technical publications.

T Tank Farm Interim Surface Barrier Demonstration - Vadose Zone Monitoring FY09 Report  

SciTech Connect

DOE’s Office of River Protection constructed a temporary surface barrier over a portion of the T Tank Farm as part of the T Farm Interim Surface Barrier Demonstration Project. As part of the demonstration effort, vadose zone moisture is being monitored to assess the effectiveness of the barrier at reducing soil moisture. A solar-powered system was installed to continuously monitor soil water conditions at four locations (i.e., instrument Nests A, B, C, and D) beneath the barrier and outside the barrier footprint as well as site meteorological conditions. Nest A is placed in the area outside the barrier footprint and serves as a control, providing subsurface conditions outside the influence of the surface barrier. Nest B provides subsurface measurements to assess surface-barrier edge effects. Nests C and D are used to assess changes in soil-moisture conditions beneath the interim surface barrier. Each instrument nest is composed of a capacitance probe (CP) with multiple sensors, multiple heat-dissipation units (HDUs), and a neutron probe (NP) access tube. The monitoring results in FY09 are summarized below. The solar panels functioned normally and could provide sufficient power to the instruments. The CP in Nest C after September 20, 2009, was not functional. The CP sensors in Nest B after July 13 and the 0.9-m CP sensor in Nest D before June 10 gave noisy data. Other CPs were functional normally. All the HDUs were functional normally but some pressure-head values measured by HDUs were greater than the upper measurement-limit. The higher-than-upper-limit values might be due to the very wet soil condition and/or measurement error but do not imply the malfunction of the sensors. Similar to FY07 and FY08, in FY09, the soil under natural conditions (Nest A) was generally recharged during the winter period (October-March) and discharged during the summer period (April-September). Soil water conditions above about 1.5-m to 2-m depth from all three types of measurements (i.e., CP, NP and HDU) showed relatively large variation during the seasonal wetting-drying cycle. For the soil below 2-m depth, the seasonal variation of soil water content was relatively small. The construction of the surface barrier was completed in April 2008. In the soil below the surface barrier (Nests C and D), the CP measurements showed that water content at the soil between 0.6-m and 2.3-m depths was very stable, indicating no climatic impacts on soil water condition beneath the barrier. The NP-measured water content showed that soil water drainage seemed occurring in the soil between about 3.4 m (11 ft) and 9.1 m (30 ft) in FY09. The HDU-measured water pressure decreased consistently in the soil above 5-m depth, indicating soil water drainage at these depths of the soil. In the soil below the edge of the surface barrier (Nest B), the CP-measured water content was relatively stable through the year except at the 0.9-m depth; the NP-measured water content showed that soil water drainage was occurring in the soil between about 3.4 m (11 ft) and 9.1 m (30 ft) but at a slightly smaller magnitude than those in Nests C and D; the HDU-measurements show that the pressure head changes in FY09 in Nest B were less than those for C and D but more than those for A. The soil-water-pressure head was more sensitive to soil water regime changes under dry conditions. In the soil beneath the barrier, the theoretical steady-state values of pressure head is equal to the negative of the distance to groundwater table. Hence, it is expected that, in the future, while the water content become stable, the pressure head will keep decreasing for a long time (e.g., many years). These results indicate that the T Tank Farm surface barrier was performing as expected by intercepting the meteoric water from infiltrating into the soil and the soil was becoming drier gradually. The barrier also has some effects on the soil below the barrier edge but at a reduced magnitude.

Bomb-Pulse Chlorine-36 at the Proposed Yucca Mountain Repository Horizon: An Investigation of Previous Conflicting Results and Collection of New Data  

SciTech Connect

Previous studies Los Alamos National Laboratory (LANL) found elevated ratios of chlorine-36 to total chloride (36Cl/Cl) in samples of rock collected from the Exploratory Studies Facility (ESF) at Yucca Mountain (YM). The data were interpreted as an indication that fluids containing “bomb-pulse” 36Cl reached the repository horizon in the ~50 years since the peak period of above-ground nuclear testing. Due to the significance of 36Cl data to conceptual models of unsaturated zone flow, the United States Geological Survey (USGS) implemented a study to validate the LANL findings. The USGS drilled new boreholes at select locations across zones where bomb-pulse ratios had previously been identified. The drill cores were analyzed at Lawrence Livermore National Laboratory (LLNL). Because consensus was not reached between the USGS/LLNL and LANL on several fundamental points including the presence or absence of bomb-pulse 36Cl, an evaluation by the University of Nevada, Las Vegas (UNLV), was initiated. The overall objectives of the UNLV study were to investigate the source of the validation study’s conflicting results, and to obtain additional data on bomb-pulse isotopes at the repository horizon. UNLV engaged in discussions with previous investigators, reviewed reports, and analyzed archived samples. UNLV also collected new samples of rock from the ESF, soil profiles from the surface of YM, and samples of seep water from inside the ESF. Samples were analyzed for 36Cl/Cl ratios, and 99Tc and 129I in select samples. A column experiment was conducted mimicking the passage of bomb-pulse 36Cl through YM tuff. The work faced several obstacles including an extended shutdown of the tunnel. Only one sample yielded a background corrected 36Cl/Cl ratio that was higher than the accepted bomb-pulse threshold (1250 x 10-15). Specimen 01034214 obtained from the Drill Hole Wash fault (19+33) had a ratio of 1590 ± 80 (1?) x10-15, whereas the other separate sample from this fault zone yielded 1160 ± 50 (1?) x 10-15. Three samples collected from Alcove 6 averaged 490 ± 100 (1?) x10-15; a sample from Sundance Fault resulted in a ratio of 920 ± 60 (1?) x10-15, and a sample from the Bow Ridge Fault produced 530 ± 20 (1?) x10-15. The results are significant because: 1) they tend to be lower than LANL data for comparable samples, albeit in agreement with the range of data produced in the area, and 2) they show that a bomb-pulse 36Cl/Cl ratio was measured in rock collected at the repository horizon level by a second and independent group of investigators (UNLV). Because of time UNLV was not able to replicate the results, and these few data points are insufficient to draw major and definitive conclusions. Leachates of soil samples collected from the surface above the ESF yielded several ratios with bomb-pulse 36Cl, particularly for samples encompassing the wetting front. Soil samples collected above the south ramp, where there was limited soil coverage due to a large amount of rock outcrop, had relatively large ratios ranging from 2170 ± 110 (1?) x10-15 to 5670 ± 350 (1?) x10-15. Soil samples from profiles from above the north ramp ranged from 820 ± 70 (1?) x10-15 to 2390 ± 160 (1?) x10-15, which compare favorably with previous measurements near the site. Water seepage into the ESF south ramp and 36Cl standards made from NIST material were also analyzed. The standards were produced to have nominal 36Cl/Cl ratios (10-15) of 500, 2,500 and 10,000 and the results showed good agreement with the calculated ratios. The seepage samples ranged between 680 ± 40 (1?) x10-15 to 1110 ± 40 (1?) x10-15, consistent with that found for modern meteoric water, with a small bomb-pulse component. Bomb-pulse 36Cl may not have been incorporated in this fast-path water because the surface above the infiltration zone consists mostly of outcrop and the flow pathways have probably mostly been leached. 99Tc was measured in five of nine leaches of ESF rock but poor analytical recoveries and lack of data overlap with 36Cl limit interpretations of these data
