DOE oil shale reference sample bank: Quarterly report, July-September 1987

Description: The DOE Oil Shale Program was restructured in FY84 to implement a 5-year period of basic and applied research in the study of the phenomena involved in oil shale pyrolysis/retorting. The program calls for the study of two reference shales per year for a period of 5 years. Consequently, the program calls for the identification, acquisition, processing, characterization, storage, disbursement, and record keeping for ten reference shales in a period of 5 years. Two FY86 and one FY87 reference shal… more

Improving the performance of brine wells at Gulf Coast strategic petroleum reserve sites

Description: At the request of the Department of Energy, field techniques were developed to evaluate and improve the injection of brine into wells at Strategic Petroleum Reserve (SPR) sites. These wells are necessary for the disposal of saturated brine removed from salt domes where oil is being stored. The wells, which were accepting brine at 50 percent or less of their initial design rates, were impaired by saturated brine containing particulates that deposited on the sand face and in the geologic formatio… more

Evaluation of the production potential of the Crystal Hot Springs geothermal resource, north central Utah

Description: Results of an artesian flow test of a 1000 foot deep well (USP/TH-1) are reported. The testing program was designed to provide necessary data for estimating the long-term production potential of the geothermal resource. Based on results of a 72 hour flow test, it was concluded that the state-owned portion of the Crystal Hot Springs resource is potentially capable of supplying sufficient energy to provide space and hot water heating for the minimum security portion of the Utah State Prison.

Particle confinement in EBT reactors with noncircular mirror coils

Description: Methods of improving single particle confinement in the vacuum magnetic field of an ELMO Bumpy Torus (EBT) reactor have heretofore focused on enhancement of the effective magnetic aspect ratio through the addition of relatively low current supplementary coils to the basic EBT configuration of toroidally linked circular mirror coils. This method of aspect ratio enhancement is reviewed and compared to the use of noncircular, D-shaped mirror coils. A critical parameter in this evaluation is the re… more

Configurational analysis of an EBT reactor in various magnetic geometries

Description: Optimization of vacuum field particle confinement in an ELMO Bumpy Torus (EBT) reactor has been considered. Several methods of improving the efficient utilization of magnetic fields and the particle confinement characteristics of a reactor have been analyzed. These include the use of (1) magnets with a large mirror ratio, (2) high field Nb/sub 3/Sn or Nb/sub 3/Sn/NbTi hybrid mirror coils, (3) split-wedge mirror coils, (4) aspect ratio enhancement (ARE) coils, and (5) recently developed field sy… more

Using surface waters for supplementing injection at the Salton Sea Geothermal Field (SSGF), Southern California

Description: The flash-steam conversion cycle is most suitable for electric power production at the SSGF. However, large-scale development of the SSGF may require use of makeup water supplements to injected brine for a viable reservoir pressure maintenance program. Since steam condensate will probably be required to satisfy power plant cooling needs, local surface waters have been evaluated for their potential use as sources of injection makeup. It was found that direct injection of untreated makeup water i… more

Automated system for membrane filtration and core tests. [For assessing injectability of geothermal fluids]

Description: An existing manually operated LLL system for obtaining data on injectability of geothermal effluents has been automated. Membrane filters and core samples are exposed to geothermal brine at representative injection pressure and formation confining pressure to study the potential effects of scaling and suspended solids deposition on the performance of injection wells. An electronic controller provides for operation under conditions of either constant differential pressure or constant flow. A dat… more

Potential methods for methane extraction from geopressured brine at high temperature and pressure

Description: Recovery of methane from Gulf Coast geopressured-geothermal reservoirs does not appear to be profitable without a rise in natural gas prices to offset high production costs. If injection into the production reservoir becomes necessary to maintain productivity and to minimize subsidence, the injection pumping costs approach and even exceed the value of the recoverable methane. An option aimed at reducing the injection pump operating costs is to maintain a higher than normal pressure at the produ… more

Potential uses for a high-temperature borehole gravimeter

Description: It is possible to design a canister to cool a borehole gravimeter for use in geothermal and high-temperature (up to 350/sup 0/C) gas wells. Repeat surveys with such a gravimeter could (1) help estimate the extent of reservoir plugging in geothermal injection well after one year of operation and (2) detect compaction of a geothermal aquifer if the change in thickness of the aquifer exceeds 1 m. The instrument could be used together with conventional logging tools to evaluate radial dependence of… more

Inhibiting Deposition of Siliceous Scale

Description: Lawrence Livermore Laboratory is developing the TOTAL FLOW process for efficient utilization of the thermal energy stored in high temperature-high salinity brines from the Salton Sea Geothermal Field (SSGF) for electric power production. Energy conversion is accomplished by flowing brine through mixed phase expanders and directing the high velocity exhaust jets onto the blades of an impulse turbine. Previous field experience, however, at the Sinclair No. 4 site in the SSGF indicated that deposi… more

Effective H{sub 2}S abatement process using geothermal brine effluents

Description: A simple and potentially inexpensive method for removal of H/sub 2/S from noncondensible gases evolved in geothermal flash processes has been successfully tested on a small scale in the field. The method consists of scrubbing the noncondensible gases of H{sub 2}S with brine effluents which contain relatively high concentrations of Pb, Zn, and Fe such as those of the Salton Sea and Brawley Geothermal Fields in the Imperial Valley, California. For plant applications, noncondensibles including H{s… more

Evaluation of geopressured brine injectability: Department of Energy, Pleasant Bayou No. 2 well, Brazoria County, Texas

Description: A field evaluation of geopressured brine injectability was completed during September 22 to 25, 1980 at the DOE, Brazoria test site in Texas. Membrane filters, with pore sizes of 0.4-..mu..m and 10.0-..mu..m, were used as the basis for obtaining suspended solids data and for developing performance-life estimates of typical spent brine injection wells. Field measurements were made at 130/sup 0/C and line pressures up to 3800 psig. Scale inhibited (phosphonate-polyacrylate threshold-type, carbona… more

Predicting the Rate by which Suspended Solids Plug Geothermal Injection Wells

Description: Standard membrane filtration tests have been used by the oil industry for more than 20 years to evaluate injection well performance. Published analytical models are also available fore relating filtration data to injector lifetimes. We have utilized these techniques to evaluate injection at the Salton Sea Geothermal Field, Southern California. Results indicate that direct injection into reservoir zones with primary porosity is not feasible unless 1-micrometer or larger particulates formed durin… more
