Long-term seismic monitoring of the Roosevelt - Cove Fort KGRA's

Description: Earthquake monitoring of the Roosevelt-Cove Fort Hot Springs KGRA's was implemented by installation of three RF telemetered, vertical component, seismograph stations: CFU, MNU and RHU. These station sites were selected on the basis of proximity to the KGRA's, with respect to known earthquake activity determined in the microearthquake surveys. The three permanent stations form the basic long-term monitoring capability of the Roosevelt-Cove Fort KGRA's. The signals are FM transmitted to a collecting site near Milford then they are telephone-transmitted to the University of Utah campus for recording. The limitations of only three-stations precludes accurate hypocenter determinations but allows detection to a minimum threshold of about M-0.5 for close-in events. Locations can be determined for earthquakes of about M-0.7 or greater. Regional coverage of the south-central Utah KGRA's is supplemented by the use of other existing University of Utah stations to the east: MSU, PUU, and RFU. Together the six stations allow long-term detection of this geothermally active region.

Monroe, Utah, Hydrothermal System: Results from Drilling of Test Wells MC1 and MC2

Description: Following detailed geological (Parry et al., 1976; Miller, 1976) and geophysical (Mase, Chapman, and Ward, 1978; Kilty, Mase, and Chapman, 1978) studies of the Monroe, Utah hydrothermal system, a program of drilling two intermediate depth test wells was undertaken. The objectives of the test well drilling were three-fold: (1) to obtain structural information bearing on the poorly known dip of the Sevier Fault, (2) to obtain temperature information below the shallow depths (approximately 300 ft.) sampled in the first phase of exploration, and (3) to provide cased wells which could act as monitor wells during the production phase of the project. The test well drilling was seen to be vital to the selection of a site for a production well. This report describes the results from the drilling of the two test wells, designated MC1 and MC2, and offers interpretation of the hydrothermal system which may be used as a basis for selecting production wells.

Well cost estimates in various geothermal regions

Description: A project to estimate well costs in regions of current geothermal activity has been initiated. Costs associated with commonly encountered drilling problems will be included. Activity-based costing techniques will be employed to allow the identification of cost drivers and the evaluation of the economic effects of new technologies and operational procedures on well costs. The sensitivity of well costs to a number of parameters such as rate-of-penetration and daily operating costs will be examined. Additional sensitivity analyses and trade-off studies will evaluate the efficiency of various operational practices and preventive, as well as remedial, actions. These efforts should help provide an understanding of the consumption of resources in geothermal drilling.

Final Report, Volume 77-5

Description: This report covers the following Tasks: Task 76.1.21--Color photos: Stereo color aerial photographs were made available to industry for copying at industry's expense on November 28, 1977 at 11:00 a.m. This final report on this task merely records that fact. Task 77.1.14--Proposal Review (MOD A002)--All activities under this task have been completed. No tangible deliverables were required. Task 76.1.14--Simultaneous modeling of multiple data sets: A technique for simultaneous inversion of MT and Schlumberger data was developed and tested on some available deep crustal data from South Africa. The publication resulting and included herewith is: 'Ridge Regression Inversion Applied to Crustal Resistivity Sounding Data from South Africa', Geophysics, Volume 42, No.5, pages 995-1005. Joint inversion of Schlumberger and electromagnetic sounding data was developed and applied to geothermal data from Roosevelt Hot Springs KGRA. The publication resulting and included herewith is: 'Electromagnetic and Schlumberger Resistivity Sounding in the Roosevelt Hot Springs KGRA', Geophysics, in press. To utilize multiple inversion schemes at a convective hydrothermal system in the Eastern Great Basin will require applications of three-dimensional forward algorithms now available for gravity, magnetics, and AMT/MT. Unfortunately the pertinent data sets available for Roosevelt Hot Springs KGRA (or Monroe Hot Springs KGRA, for that matter) are not compatible since the physical property distributions giving rise to the gravity field is not coincident with that giving rise to the magnetic field, and so on. Thus, they have turned to interpreting each data set independently and then drawing a schematic model of the subsurface which accepts all data sets. An example of this procedure is contained in 'Geophysics of the Roosevelt Hot Springs Thermal Area, Utah', submitted to Geology and included in Final Report Volume 77-2. Task 76.1.11--Drill and Log 10 Heat Flow Holes: All thermal gradients and heat flows appear in Technical Report 77-3. The ...

A thermal resistance method for computing surface heat flow and subsurface temperatures with application to the Uinta Basin of northeastern Utah

Description: The thermal resistance method has been modified to test the utility of oil and gas well bottom-hole temperature data in determining heat flow and subsurface temperature patterns. Thermal resistance, defined as the quotient of a depth parameter '{Delta}{sub z}' and thermal conductivity 'k'', governs subsurface temperatures as follows: T{sub B} = T{sub 0} + q{sub 0} B {summation} z=0 ({Delta}z/k){sub i} where T{sub B} is the temperature at depth z = B, T{sub 0} is the surface temperature, q{sub 0} is surface heat flow and the thermal resistance ({Delta}z/k) is summed for all lithological units between the surface and depth B. In practice, bottom-hole temperatures are combined with a measured or estimated thermal conductivity profile to determine the surface heat flow q{sub 0}, which in turn is used for all consequent subsurface temperature computations. The method has been tested in the Tertiary Uinta Basin of northeastern Utah, a region of intermediate geologic complexity (structurally simple yet lithologically complex) where numerous oil and gas well data are available. Thermal conductivity values, determined for 852 samples from five representative wells varying in depth from 670 to 5180 meters, were used to assign average conductivities to geologic formations and to investigate the effect of facies changes on intra-formation conductivities. In situ conductivities were corrected for porosity and temperature effects. Formation thicknesses needed for the thermal resistance summation were obtained by utilizing approximately 2000 wells in the WEXPRO Petroleum Information file, the computations being expedited by describing all formation contacts as fourth order polynomial surfaces. Bottom-hole temperatures were used from 97 selected wells where multiple well logs permitted correcting temperatures for drilling effects.

Utah State Prison Space Heating with Geothermal Heat - Resource Assessment Report Crystal Hot Springs Geothermal Area

Description: Reported herein is a summary of work conducted under the Resource Assessment Program-Task 2, for the Utah State Prison Geothermal Space Heating Project at Crystal Hot Springs, Draper, Utah. Assessment of the geothermal resource in and around the Utah State Prison property began in october of 1979 with an aeromagnetic and gravity survey. These tasks were designed to provide detailed subsurface structural information in the vicinity of the thermal springs so that an informed decision as to the locations of test and production holes could be made. The geophysical reconnaissance program provided the structural details needed to focus the test drilling program on the most promising production targets available to the State Prison. The subsequent drilling and well testing program was conducted to provide information to aid fin the siting and design of a production well and preliminary design activities. As part of the resource assessment portion of the Utah State Prison Geothermal Project, a program for periodic geophysical monitoring of the Crystal Hot Springs resource was developed. The program was designed to enable determination of baseline thermal, hydraulic, and chemical characteristics in the vicinity of Crystal Hot Springs prior to production and to provide a history of these characteristics during resource development.
