This letter report describes the technical activities of the waste element solubility study during Fiscal Year (FY88, October 1, 1987 to September 30, 1988). This experimental waste element solubility study provides experimentally determined limits on radionuclide concentrations in groundwater from Yucca Mountain. Furthermore, the results of this study are essential for verifying the validity of radionuclide transport calculations, and for providing the maximum concentrations for the radionuclide sorption tests. Solubility is the source term for radionuclide transport calculations. The solubility in this study is controlled by fewer variables than are used in the multiparameter transport model. Therefore, modeling must be capable of predicting the results of this waste element solubility study. Agreement between the experimental result and the modeling predictions will validate the geochemical module of the transport model. 3 refs., 8 figs.

The U.S. Interagency Geothermal Coordinating Council was a multi-agency group charged with identifying and reducing barriers to geothermal energy development in the U.S. Many of the issues covered related to regulations for and progress in the leasing of Federal lands in the West for power development. The IGCC reports are important sources of historical information. (DJE 2005)

In the 1970's, the nation's attention was focused on Energy. This focus shifted to the Economy in the 80's with the concerns about the federal deficit. Emphasis has now moved to the Environment for the 1990's with the other two ''E's'' remaining as lingering concerns. Obviously geothermal resources have positive impacts on the three E's since they provide energy with limited environmental impact. However, they all are aware of the environmental concerns and must address them for the industry. Two current global environmental concerns discussed in this paper are the ''greenhouse effect'' and acid rain. Both of these areas have been emphasized by President Bush, and legislation is pending in both state and federal legislatures to address these problems. They need to understand the impact of geothermal energy production in these areas, and from a DOE viewpoint, identify R and D that is critical to meeting existing and pending regulations and laws.

In order to assure the continued development of geothermal resources, many advances in materials technology are required so that high costs resulting from the severe environments encountered during drilling, well completion and energy extraction can be reduced. These needs will become more acute as higher temperature and chemically aggressive fluids are encountered. High priority needs are for lost circulation control and lightweight well completion materials, and tools such as drill pipe protectors, rotating head seals, blow-out preventers, and downhole drill motors. The lack of suitable hydrolytically stable chemical systems that can bond previously developed elastomers to metal reinforcement is a critical but as yet unaddressed impediment to the development of these tools. In addition, the availability of low cost corrosion and scale-resistant tubular lining materials would greatly enhance transport and energy extraction processes utilizing hypersaline brines. Work to address these materials needs is underway at Brookhaven National Laboratory (BNL), and recent accomplishments are summarized in the paper.

Geopressured reservoirs exhibit pressure gradients in excess of the normal hydrostatic gradient. In the Gulf Coast area the normal gradient is 0.465 psi/ft. Pressures may approach lithostatic pressure and have been measured as high as 1.05 psi/ft in the Gulf Coast area. Geopressured basins exist worldwide and in a number of U.S. locations, east, west, north and south. The Gulf Coast area has been studied extensively and is the subject of the DOE geopressured-geothermal research at present. The assumed ranges in resource characteristics include: depth from -12,000 to > -20,000 feet, brine flow rate from 20,000 to 40,000 bpd, temperature from 300 to 400 F, bottomhole pressure from 12,000 to 18,500 psi; salinity from 20,000 to 200,000 mg/L, gas-water ratio from 40 to 80 scf/bbl., and condensate from a trace to production. Energy in the geopressured resource includes gas, thermal, and hydraulic energy. It has been estimated that there are 6,000 quads of methane and 11,000 quads of thermal energy in the Gulf Coast area geopressured-geothermal reservoirs. Estimates run as high as 50,000 quad for the thermal energy (Wallace et al, 1978). Present industrial interest in the Pleasant Bayou and Hulin wells includes: desalination plants, an economic study by a …

Logging research at The University of Texas has been carried out in several areas. We have studied how rock resistivity varies with water saturation when other variables, such as rock wettability, stress, saturation history, and shale content are varied. Both experimental and theoretical work have been done. Rock wettability (oil or water wet) has by far the largest effect. Shale content and saturation history are also important. Rock stress is the least important, at least in the Berea sandstones and glass bed packs we have studied. We have published several papers and theses which describe this work in detail. We have also studied the effect of certain trace elements (boron, mainly) on the neutron log. Boron has a very high thermal neutron capture cross Section. Analyses of a number of Frio formation cores from the Texas Gulf Coast area show that boron occurs frequently in these rocks in amounts (up to 100 ppm or more) that would seriously affect several procedures in neutron log interpretation. It could, for example, reduce or even eliminate the neutron log--density log porosity reversal that is commonly used as a gas indicator. A recent paper reports details of our work in the Frio. We are …

Up to 500,000 Quads of thermal energy are believed to be contained in crustal magma bodies within the U.S. at temperatures in excess of 600 C and at depths less than 10 km. Scientific feasibility of utilizing this energy resource was concluded after a seven-year study that culminated in successful energy extraction experiments in molten rock at Kilauea Iki lava lake. The current DOE program is developing technology to experimentally extract energy from a silicic magma body so that engineering feasibility of the magma energy concept can be evaluated. At this point, significant progress has been achieved in three areas: Geophysics and site selection. Energy Extraction Processes, and Geochemistry/Materials. Future activities will be focused by drilling and evaluating a deep exploratory well in Long Valley caldera where active magma is expected.

Extensive laboratory studies have indicated that the application of biochemical processes in the development of biotechnology suitable for conversion of geothermal wastes from hazardous to non-hazardous materials is technically and economically feasible. These studies have also shown that such biotechnology may require bioreactors capable of handling different amounts and types of residual sludges. Particular attention has to be paid to the duration of treatment, efficiency of cycling, and maintenance of biomass. Laboratory studies addressing these parameters are described.

My assignment is to give feedback on the Reservoir Technology Task portion of the DOE-sponsored work we've been hearing about. Briefly, you've done well in adapting to an increasingly tough budgetary and political environment. More specifically, I'd like to highlight some of the encouraging developments in the context of overall research strategy. Ted Mock on Tuesday and Ken Nemzer at yesterday's luncheon made several useful observations and I'd like to refer to just two in relation to Reservoir Technology. Ted observed that product development can proceed along two paths. We might call these the Big Bang or the Evolutionary lines. He correctly pointed out the difficulty American industry has had with commercializing incremental (Evolutionary) product improvements. In this context Reservoir Technology development is more like manufacturing engineering because we aren't developing new products, for the most part. We are simply working to produce electricity or process heat cheaper. The DOE has listened to industry on this point and their statement of objectives sounds excellent. Let me quote one example from Page 10 of the December 20, 1988 report. For ''Reservoir Evaluation'' we read ''Decrease uncertainties...20% by 1993''. I confess that I don't know what the uncertainty is in 1989, but …
