Energy Program annual report

Description: The national economy is particularly dependent on efficient electrical generation and transportation. Electrical demand continues to grow and will increasingly rely on coal and nuclear fuels. The nuclear power industry still has not found a solution to the problem of disposing of the waste produced by nuclear reactors. Although coal is in ample supply and the infrastructure is in place for its utilization, environmental problems and improved conversion processes remain technical challenges. In … more

Development of passive electronic components for instrumentation of improved geothermal logging tools and components. Annual progress report

Description: Short term objectives for well-logging instrumentation are circuits which can operate at temperatures in the range 275/sup 0/C to 350/sup 0/C; the medium term goal is operation up to 500/sup 0/C, and the long term goal is to achieve operation at 1000/sup 0/C. It is apparent that useful electronic circuits will require the combination of both passive components and active devices. In order to meet the compatibility requirements, the basic technology which has been selected in this project is the… more

Investigation and evaluation of geopressured-geothermal wells

Description: Over the life of the project, 1143 wildcat wells were screened for possible use. Although many did not meet the program's requirement for sand development, a surprisingly large number were abandoned because of downhole mechanical problems. Only 94 of these wells were completed as commercial hydrocarbon producers. Five wells of opportunity were funded for testing. Of these, two were evaluated for their hydraulic energy, thermal energy, and recoverable methane, and three were abandoned because of… more

Analysis of flow data from the DOW/DOE L. R. Sweezy No. 1 well

Description: This topical report presents the results of work to-date on the analysis and simulation of flow and pressure data from the testing of the L.R. Sweezy No. 1 well. Analysis of drawdown data indicates a formation permeability of around 126 md, and a flow-rate dependent skin. The conventional analysis techniques were, however, found to be inadequate for analyzing the buildup data. The formation properties inferred from the drawdown were used together with the CHARGR simulator to simulate the produc… more

Testing geopressured geothermal reservoirs in existing wells. Wells of Opportunity Program final contract report, 1980-1981

Description: The geopressured-geothermal candidates for the Wells of Opportunity program were located by the screening of published information on oil industry activity and through direct contact with the oil and gas operators. This process resulted in the recommendation to the DOE of 33 candidate wells for the program. Seven of the 33 recommended wells were accepted for testing. Of these seven wells, six were actually tested. The first well, the No. 1 Kennedy, was acquired but not tested. The seventh well,… more

5MW Raft River facility experience

Description: The Raft River geothermal plant is a small binary cycle conversion system which uses isobutane as the working fluid. This plant uses a staged boiler concept to achieve better performance than could be obtained by a single boiler. The plant was designed to operate with a geothermal water inlet temperature of 143/sup 0/C (290/sup 0/F) and produce a nominal generator output of 5MW. The plant is supported by a supply and injection system consisting of three supply wells (about 1524m or 5000 ft deep… more

Lithologic descriptions and temperature profiles of five wells in the southwestern Valles caldera region, New Mexico

Description: The subsurface stratigraphy and temperature profiles of the southern and western Valles caldera region have been well constrained with the use of data from the VC-1, AET-4, WC 23-4, PC-1 and PC-2 wells. Data from these wells indicate that thermal gradients west of the caldera margin are between 110 and 140)degrees)C/km, with a maximum gradient occurring in the bottom of PC-1 equal to 240)degrees)C/km as a result of thermal fluid flow. Gradients within the caldera reach a maximum of 350)degrees)… more

Preliminary targeting of geothermal resources in Delaware. Progress report, July 15, 1978-July 14, 1979

Description: Results of temperature logging the five DOE 1000 foot test wells in Delaware indicate that the potential is good for a relatively low temperature geothermal resource (temperatures less than about 80/sup 0/C). A preliminary Bouguer gravity map was made for portions of Kent and Sussex counties in order to detect gravity anomalies possibly related to granitic plutons. The map indicates a gravity low trending northeast-southwest across Sussex County that could be indicative of other structural feat… more

Results of acid treatments in hydrothermal direct heat experiment wells

Description: Matrix acid treatments have been employed in two low-to-moderate temperature hydrothermal wells with successful results. These two wells showed flow rate increases of 40% and 50%. The increased flow reduced the payback periods for the heating systems to nearly one-half of what they were before acidization. It is recommended that well designs in certain areas consider accommodating such acid stimulation techniques, if testing suggests they are warranted as a well completion tool.

Geothermal investigations in Idaho: Geothermal resource analysis in Twin Falls County, Idaho:

Description: Increased utilization of the geothermal resource in the Twin Falls - Banbury area of southern Idaho has resulted in noticeable declines in the artesian head of the system. In order to determine the nature of the declines, a network of wells was identified for monitoring shut-in pressures and temperatures. In addition, a compilation of data and reconnaissance of the areal geology was undertaken in order to better understand the geologic framework and its relationship to the occurrence of the the… more

Development of Passive Electronic Components for Instrumentation of Improved Geothermal Logging Tools and Components. Semiannual Progress Report. Report No. 1. [For Temperatures Up to 500/sup 0/C]

Description: Research progress is reported on the development of passive components, resistors, capacitors, metallization, and passivation, that will withstand well logging temperatures to 500/sup 0/C and have extremely low temperature coefficients. The lower the temperature coefficients, the more exacting the instrumentation designs can be without elaborate compensation techniques. The method of fabricating the thin film components is that of chemical vapor deposition (CVD) which is a major deviation from … more

Open hole packer and running procedure for hot dry rock reservoir testing

Description: An acute need for open hole packers for high pressure, high temperature operations at the Fenton Hill, Hot Dry Rock (HDR) Geothermal Site has existed since 1981. Cemented-in-liners were used instead of packers while packer technology was brought up to HDR requirements. A reservoir development and evaluation program has just been completed with 5 successful open hole packer runs. These 5 successful runs were the result of: (1) R and D leading to improved packer materials and design, (2) an impro… more
