Geology of the central Mineral Mountains, Beaver County, Utah
The Mineral Mountains are located in Beaver and Millard Counties, southwestern Utah. The range is a horst located in the transition zone between the Basin and Range and Colorado Plateau geologic provinces. A multiple-phase Tertiary pluton forms most of the range, with Paleozoic rocks exposed on the north and south and Precambrian metamorphic rocks on the west in the Roosevelt Hot Springs KGRA (Known Geothermal Resource Area). Precambrian banded gneiss and Cambrian carbonate rocks have been intruded by foliated granodioritic to monzonitic rocks of uncertain age. The Tertiary pluton consists of six major phases of quartz monzonitic to leucocratic granitic rocks, two diorite stocks, and several more mafic units that form dikes. During uplift of the mountain block, overlying rocks and the upper part of the pluton were partially removed by denudation faulting to the west. The interplay of these low-angle faults and younger northerly trending Basin and Range faults is responsible for the structural control of the Roosevelt Hot Springs geothermal system. The structural complexity of the Roosevelt Hot Springs KGRA is unique within the range, although the same tectonic style continues throughout the range. During the Quaternary, rhyolite volcanism was active in the central part of the range …

Use of an acoustic borehole televiewer to investigate casing corrosion in geothermal wells
Corrosion of well and surface equipment due to the presence of hot, corrosive brines is one of the major problems facing geothermal operators. For wellbore casing, this problem is complicated by the fact that in-place inspection is difficult at best. In an attempt to improve this situation, a prototype acoustic borehole televiewer designed to operate in geothermal wells was used to study the corrosion damage to casing in three commercial wells. The results of this experiment were promising. The televiewer returns helped to define areas of major corrosion damage and to indicate the extent of the damage. This paper briefly discusses the corrosion problem, describes the acoustic borehole televiewer, and then summarizes the results of the field test of the televiewer's capability for investigating corrosion.

Occurrence of oil and gas in Devonian shales and equivalents in West Virginia
During the Devonian, an epicontinental sea was present in the Appalachian basin. The Catskill Clastic Wedge was formed in the eastern part of the basin by sediments derived from land along the margin of the continent. Three facies are recognized in the Catskill Clastic Wedge: (1) a red-bed facies deposited in terrestrial and nearshore marine environments; (2) a gray shale and sandstone facies deposited in a shallow- to moderately-deep marine environment; and (3) a dark-gray shale and siltstone facies deposited in the deepest part of the epicontinental sea. Oil and natural gas are being produced from Devonian shales in the western part of West Virginia and from upper Devonian sandstones and siltstones in the north-central part of the state. It is suggested that in addition to extending known areas of gas production, that drilling for natural gas be conducted in areas underlain by organic-rich shales and thick zones of interbedded siltstone and shale in the Devonian section in central, southern, and western West Virginia. The most promising areas for exploration are those areas where fractures are associated with folds, faults, and lineaments. 60 references.

Use of data obtained from core tests in the design and operation of spent brine injection wells in geopressured or geothermal systems
The effects of formation characteristics on injection well performance are reviewed. Use of data acquired from cores taken from injection horizons to predict injectivity is described. And methods for utilizing data from bench scale testing of brine and core samples to optimize injection well design are presented. Currently available methods and equipment provide data which enable the optimum design of injection wells through analysis of cores taken from injection zones. These methods also provide a means of identifying and correcting well injection problems. Methods described in this report are: bulk density measurement; porosity measurement; pore size distribution analysis; permeability measurement; formation grain size distribution analysis; core description (lithology) and composition; amount, type and distribution of clays and shales; connate water analysis; consolidatability of friable reservoir rocks; grain and pore characterization by scanning electron microscopy; grain and pore characterization by thin section analysis; permeability damage and enhancement tests; distribution of water-borne particles in porous media; and reservoir matrix acidizing effectiveness. The precise methods of obtaining this information are described, and their use in the engineering of injection wells is illustrated by examples, where applicable. (MHR)

Testing geopressured geothermal reservoirs in existing wells: Detailed completion prognosis for geopressured-geothermal well of opportunity, prospect #2
A geopressured-geothermal test of Martin Exploration Company's Crown Zellerbach Well No. 2 will be conducted in the Tuscaloosa Trend. The Crown Zellerbach Well No. 1 will be converted to a saltwater disposal well for disposal of produced brine. The well is located in the Satsuma Area, Livingston parish, Louisiana. Eaton proposes to test the Tuscaloosa by perforating the 7 inch casing from 16,718 feet to 16,754 feet. The reservoir pressure at an intermediate formation depth of 16,736 feet is anticipated to be 12,010 psi and the temperature is anticipated to be 297 F. Calculated water salinity is 16,000 ppm. The well is expected to produce a maximum of 16,000 barrels of water a day with a gas content of 51 SCF/bbl. Eaton will re-enter the test well, clean out to 17,000 feet, run production casing and complete the well. The disposal well will be re-entered and completed in the 9-5/8 inch casing for disposal of produced brine. Testing will be conducted similar to previous Eaton annular flow WOO tests. An optional test from 16,462 feet to 16,490 feet may be performed after the original test and will require a workover with a rig on location to perform the plugback. The …

Western gas sands project. Status report, July-August-September 1981
The progress during July, August and September 1981 on increasing gas production from low permeability gas sands of the Western United States, is summarized in this edition of the WGSP Quarterly Status Report. During the quarter, CK GeoEnergy completed the field work in the Rifle Gap area near Rifle, Colorado, as well as the Draft Phase VI report covering the prognosis about reservoir geometry in the Multi-Well site area. The improved pressure coring system project, officially terminated Sept. 30. Accomplishments included increased capabilities for the pressure core barrel, improvements in the low invasion fluid plus various laboratory core intrusion studies and improved designs for PDC drill bits. At Lawrence Livermore National Laboratory, the P/sup 2/L/sup 2/ system described last quarter was evaluated further and the decision has been made to abandon further investigation. The Los Alamos National Laboratory Ceramics Materials Group is preparing to fabricate a ceramic sample with cylindrical pores of specified diameters. The NMR data on this type sample will contribute to a better understanding of the parameters affecting NMR relaxation rates in porous media. During the quarter, modifications were made in the operating and application software of the DOE Well Test Facility, which will support additions to …

Geopressured Geothermal Drilling and Completions Technology Development Needs
Geopressured geothermal formations found in the Texas and Louisiana gulf coast region and elsewhere have the potential to supply large quantities of energy in the form of natural gas and warm brine (200 to 300/sup 0/F). Advances are needed, however, in hardware technology, well design technology, and drilling and completion practices to enable production and testing of exploratory wells and to enable economic production of the resource should further development be warranted. This report identifies needed technology for drilling and completing geopressured geothermal source and reinjection wells to reduce the cost and to accelerate commercial recovery of this resource. A comprehensive prioritized list of tasks to develop necessary technology has been prepared. Tasks listed in this report address a wide range of technology needs including new diagnostic techniques, control technologies, hardware, instrumentation, operational procedure guidelines and further research to define failure modes and control techniques. Tasks are organized into the functional areas of well design, drilling, casing installation, cementing, completions, logging, brine reinjection and workovers.

Drilling, logging and preliminary well testing of geothermal well Susan 1, Susanville, Lassen County, California
Susan 1, a hot water production well, was drilled late in 1980 for the City of Susanville, California, as part of its geothermal space-heating project. A history of drilling, logging, completion and pump testing of this well is presented. Susan 1 was drilled to 930 feet using local river water with a 17-1/2-inch bit from 50 to 540 feet and a 12-1/2-inch bit from 540 to 927 feet. A 12-3/4-inch solid casing was set from surface to 350 feet, a slotted casing from 350 to 538 feet, and a 8-5/8-inch slotted casing from 520 to 925 feet. Interpretations of the following logs and test data from this well are presented: drilling logs (penetration rate, water loss and gain, return temperatures); formation logs (description of well cuttings, caliper, spontaneous potential, electrical resistivity, gamma ray, neutron); production logs (temperature, spinner); and pump test data.

Monitoring well systems in geothermal areas
The ability to monitor the injection of spent geothermal fluids at reasonable cost might be greatly improved by use of multiple-completion techniques. Several such techniques, identified through contact with a broad range of experts from the groundwater and petroleum industries, are evaluated relative to application in the typical geologic and hydrologic conditions of the Basin and Range Province of the Western United States. Three basic monitor well designs are suggested for collection of pressure and temperature data: Single standpipe, multiple standpipe, and closed-system piezometers. A fourth design, monitor well/injection well dual completions, is determined to be inadvisable. Also, while it is recognized that water quality data is equally important, designs to allow water sampling greatly increase costs of construction, and so such designs are not included in this review. The single standpipe piezometer is recommended for use at depths less than 152 m (500 ft); several can be clustered in one area to provide information on vertical flow conditions. At depths greater than 152 m (500 ft), the multiple-completion standpipe and closed-system piezometers are likely to be more cost effective. Unique conditions at each monitor well site may necessitate consideration of the single standpipe piezometer even for deeper completions.

Geothermal field case studies that document the usefulness of models in predicting reservoir and well behavior
The geothermal industry has shown significant interest in case histories that document field production histories and demonstrate the techniques which work best in the characterization and evaluation of geothermal systems. In response to this interest, LBL has devoted a significant art of its geothermal program to the compilation and analysis of data from US and foreign fields (e.g., East Mesa, The Geysers, Susanville, and Long Valley in California; Klamath Falls in Oregon; Valles Caldera, New Mexico; Cerro Prieto and Los Azufres in Mexico; Krafla and Nesjavellir in Iceland; Larderello in Italy; Olkaria in Kenya). In each of these case studies we have been able to test and validate in the field, or against field data, the methodology and instrumentation developed under the Reservoir Technology Task of the DOE Geothermal Program, and to add to the understanding of the characteristics and processes occurring in geothermal reservoirs. Case study results of the producing Cerro Prieto and Olkaria geothermal fields are discussed in this paper. These examples were chosen because they illustrate the value of conceptual and numerical models to predict changes in reservoir conditions, reservoir processes, and well performance that accompany field exploitation, as well as to reduce the costs associated with …

User manual for IOSYM: an input-oriented simulation language for continuous systems
IOSYM is an extension of the GASP IV simulation language. It permits systems which are sequences of continuous processes to be modeled graphically. Normally the system can be described by data input only. The language permits stochastic sequencing and termination criteria for processes and allows crossing conditions for ending operations that are more general than GASP IV. Extensive capability exists for conditional branching and logical modification of the network. IOSYM has been used to model the cost of geothermal drilling where the various costly processes of drilling are represented by IOSYM operations. The language is much more general, however, since it retains most of GASP IV's discrete event capabilities and permits easy modeling of continuous processes.

Pumping tests of well Campbell et al. No. 2, Gila Hot Springs, Grant County, New Mexico
Well Campbell et al. No. 2 near Gila Hot Springs in southwestern New Mexico (Section 5, Township 13 South, Range 13 West) was pumped for a five-step test and a 48-hour constant-rate test during October 1981. Measurements included depth to water in the pumping well and two observation wells, and discharge rates at the pumping well and two springs. The water level in the pumping well responded during both tests. However, water-level changes in the observation wells were too small for analytical use and discharge rates from the springs showed no change. Chemical analyses of water samples collected from two springs and the pumping well show very similar water chemistries. Estimates of hydraulic properties show transmissivity from 12,000 to 14,000 gpd/ft and a storativity of 0.05. Combining these parameters with well data gives the first-year optimum discharge rate as 50 gpm with 20 feet of drawdown. Pumping this well at 50 gpm for forty years should produce only small water-level changes in wells a few hundred feet away. It would diminish the flow of the springs, and for planning purposes the combined discharge of the springs and well should be considered constant.

Hydrothermal systems in two areas of the Jemez volcanic field: Sulphur Springs and the Cochiti mining district
K/Ar dates and oxygen isotope data were obtained on 13 clay separates (<2 ..mu..m) of thermally altered mafic and silicic rocks from the Cochiti mining district (SE Jemez Mountains) and Continental Scientific Drilling Project (CSDP) core hole VC-2A (Sulphur Springs, Valles caldera). Illite with K/sub 2/O contents of 6.68%--10.04% is the dominant clay in the silicic rocks, whereas interstratified illite/smectites containing 1.4%--5.74% K/sub 2/O constitute the altered andesites. Two hydrothermal alteration events are recognized at the Cochiti area (8.07 m.y., n = 1, and 6.5--5.6 m.y., n = 6). The older event correlates with the waning stages of Paliza Canyon Formation andesite volcanism (greater than or equal to13 to less than or equal to8.5 m.y.), whereas the younger event correlates with intrusions and gold- and silver-bearing quartz veins associated with the Bearhead Rhyolite (7.54--5.8 m.y.). The majority of K/Ar dates in the hydrothermally altered, caldera-fill rocks of core hole VC-2A (0.83--0.66 m.y., n = 4) indicate that hydrothermal alteration developed contemporaneously with resurgence and ring fracture Valles Rhyolite domes (0.89--0.54 m.y.). One date of 0 +- 0.10 m.y. in acid-altered landslide debris of postcaldera tuffs from the upper 13 m of the core hole probably correlates with Holocene hydrothermal activity …
