Utilization of geothermal energy-feasibility study, Ojo Caliente Mineral Springs Company, Ojo Caliente, New Mexico

This report investigates the feasibility of a geothermal heating system at the Ojo Caliente Mineral Springs Co. The geothermal energy will be used to preheat hot water for the laundry facilities and to heat the water for a two-pipe fan coil heating system in the hotel. Present annual heating fuel costs of $11,218 for propane will be replaced by electricity to operate fans and pump at an annual cost of $2547, resulting in a net savings of $8671. Installation costs include $10,100 for a well system, $1400 for a laundry system, and $41,100 for a heating system. With the addition of a 10% design fee the total installation cost is $57,860. Ignoring escalating propane fuel prices, tax credits for energy conservation equipment, and potential funding from the State of New Mexico for a geothermal demonstration project, the simple economic payback period for this project is 6.7 years.

Weeks Island S sand reservoir B gravity stable miscible CO/sub 2/ displacement, Iberia Parish, Louisiana. Fourth annual report, June 1980-June 1981

Shell, in conjunction with the United States of America Department of Energy, is conducting a gravity stable displacement field test of the miscible CO/sub 2/ process. The test is being conducted in the portion of a fault sealed reservoir lying below a subsea depth of -12,750 feet. Injection of the CO/sub 2/ slug at the producing gas-oil contact commenced in October 1978. Injection of the 860 MM cubic foot slug was completed in February of 1980. The slug of CO/sub 2/ was moved downward through the watered out sand by production of downdip water. The leading edge of the displacement has reached the producing perforations and production of the oil column commenced on January 26, 1981. Conventional cores and the log-inject-log technique were used to determine residual oil saturation in a well drilled as the pilot producer. Pulsed neutron logging devices have been used to detect the CO/sub 2/ slug and monitor its subsequent movements in the vicinity of the production well. The monitor logs indicate the thickness of the oil column had increased during the displacement to the production perforations located 130 feet below the level of CO/sub 2/ injection. The 23 foot oil column remaining at initiation of …

Internal Technical Report, 1981 Annual Report, An Analysis of the Response of the Raft River Geothermal Site Monitor Wells

A groundwater monitoring program has been established on the Raft River Geothermal Site since 1978. The objective of this program is to document possible impacts that may be caused by geothermal production and injection on the shallow aquifers used for culinary and irrigation purposes. This annual progress report summarizes data from 12 monitor wells during 1981. These data are compared with long-term trends and are correlated with seasonal patterns, irrigation water use and geothermal production and testing. These results provide a basis for predicting long-term impacts of sustained geothermal production and testing. To date, there has been no effect on the water quality of the shallow aquifers.

Design of the Glenwood Springs downhole heat exchanger

A heat exchanger has been designed to obtain 250,000 Btu/hr from a 20-in.-diameter geothermal well at various brine temperatures. The system consists of a 10-in.-diameter plastic pipe to promote convective flow in the well and a 4-in.-diameter, Schedule 40 steel U-tube containing distilled water to extract the energy. Subject to the validity of the major assumptions, the required lengths of one leg of the U-tube at various brine temperatures are 34 ft (150/sup 0/F), 42 ft (140/sup 0/F), 54 ft (130/sup 0/F), and 75 ft (120/sup 0/F) for a mean working fluid temperature of 90/sup 0/F.

Interpretation of geophysical data from the Colado KGRA, Pershing County, Nevada

The Colado geothermal area is evidenced by hot water wells in alluvium along the west flank of the West Humboldt Range. The exploration of this geothermal system has progressed into advanced stages with completion of shallow thermal gradient drilling, two intermediate-depth exploration drill holes, one deep exploration drill hole, detailed geologic mapping, dipole-dipole resistivity, gravity, ground magnetics, MT-AMT, TDEM and assorted uncommon electrical resistivity techniques. A thermal anomaly was outlined by the shallow drilling. Dipole-dipole resistivity and gravity data along with detailed geologic mapping have suggested that this anomaly is structurally controlled. Other geophysical techniques employed do not appear to contribute to an understanding of the geothermal anomaly. The two intermediate-depth exploration holes (IGH-1, IGH-2) and the one deep hole (44x-10) may not have been located in the most favorable portions of the geothermal anomaly. The area having the greatest exploration potential for intermediate-depth drilling appears to be centered on the shallow drill hole 14 to 22. An intermediate-depth drill hole located near DH14-22 is most likely to encounter one of the conduits that allow thermal waters to rise near the surface.

Planning and drilling geothermal energy extraction hole EE-2: a precisely oriented and deviated hole in hot granitic rock

During the preceding work (Phase I) of the Hot Dry Rock (HDR) Geothermal Energy Project at Fenton Hill, two holes were drilled to a depth of nearly 3048 m (10,000 ft) and connected by a vertical hydraulic fracture. In this phase, water was pumped through the underground reservoir for approximately 417 days, producing an energy equivalent of 3 to 5 MW(t). Energy Extraction Hole No. 2 (EE-2) is the first of two deep holes that will be used in the Engineering-Resource Development System (Phase II) of the ongoing HDR Project of the Los Alamos National Laboratory. This phase of the work consists of drilling two parallel boreholes, inclined in their lower, open-hole sections at 35/sup 0/ to the vertical and separated by a vertical distance of 366 m (1200 ft) between the inclined parts of the drill holes. The holes will be connected by a series of vertical, hydraulically produced fractures in the Precambrian granitic rock complex. EE-2 was drilled to a depth of 4660 m (15,289 ft), where the bottom-hole temperature is approximately 320/sup 0/C (608/sup 0/F). Directional drilling techniques were used to control the azimuth and deviation of the hole. Upgrading of the temperature capability of existing hardware, …

Comparison of two options for supplying geothermal energy to the Veterans Administration Medical Center at Marlin, Texas

Two options for supplying geothermal energy to the Veterans Administration Medical Center (VAMC) at Marlin, Texas were compared. One option is to drill a new production well on the VAMC property, and the other is to construct a 6900-ft pipeline from an existing geothermal well to the VAMC. Technical, economic, regulatory, and institutional issues were examined during the comparison. It was concluded that neither option possesses any significant cost or regulatory advantage over the other. The new well option does involve a risk, probably small, of hitting the expected geothermal resource, whereas the pipeline option involves no similar risk. However, the pipeline option will require right-of-way negotiations and a contractual agreement between the VAMC and the owners of the existing geothermal well. Assuming that a new well is successful, that option appears to be in the best interest of the VAMC.

Hydrodynamic/kinetic reactions in liquid dominated geothermal systems: Hydroscale Test Program, Mercer 2 well site South Brawley, California (Tests No. 15--20). Final report, 27 October 1980--6 February 1981

The Aerojet Energy Conversion Company, under contract to the Los Alamos National Laboratory, US Department of Energy, has constructed and tested a mobile geothermal well-site test unit at the Mercer 2 well in South Brawley, California (Imperial Valley). The equipment controlled, monitored, and recorded all process conditions of single- and dual-flash power cycles. Single- and two-phase flashed brine effluents were flowed through piping component test sections to provide hydrodynamic/kinetic data for scale formation. The unit operated at flowrates in excess of 200 gpm and is designed to accommodate flowrates up to 300 gpm. Primary scale formations encountered were those of Pbs, Fe{sub 2} (OH){sub 3}Cl (iron hydroxychloride), iron chlorides, and non-crystalline forms Of SiO{sub 2}. The formation of iron hydroxychloride was due to the unusually high concentration of iron in the wellhead brine (5000 mg/1).

Assessment of synfuel spill cleanup options

Existing petroleum-spill cleanup technologies are reviewed and their limitations, should they be used to mitigate the effects of synfuels spills, are discussed. The six subsections of this report address the following program goals: synfuels production estimates to the year 2000; possible sources of synfuel spills and volumes of spilled fuel to the year 2000; hazards of synfuels spills; assessment of existing spill cleanup technologies for oil spills; assessment of cleanup technologies for synfuel spills; and disposal of residue from synfuel spill cleanup operations. The first goal of the program was to obtain the most current estimates on synfuel production. These estimates were then used to determine the amount of synfuels and synfuel products likely to be spilled, by location and by method of transportation. A review of existing toxicological studies and existing spill mitigation technologies was then completed to determine the potential impacts of synthetic fuel spills on the environment. Data are presented in the four appendixes on the following subjects: synfuel production estimates; acute toxicity of synfuel; acute toxicity of alcohols.
