  	Citation × Citation Citation Abstract Copy Title: Instruments for Subsurface Monitoring of Geothermal Subsidence Author: O'Rourke, J.E. Year: 1979 The requirements for a subsurface geothermal subsidence instrument were reviewed. Available instruments for monitoring subsurface displacements, both vertical and horizontal, were studied and the most capable instruments identified. Techniques and materials for improving existing or developing new instruments were evaluated. Elements of sensor and signal technology with potential for high temperature monitoring of subsidence were identified. Drawing from these studies, methods to adapt production Wells for monitoring were proposed and several new instrumentation systems were conceptually designed. Finally, four instrumentation systems were selected for future development. These systems are: triple sensor induction sensor probe (with casing collar markers); triple sensor gamma ray detector probe (with radioactive markers); triple sensor reed switch probe (with magnet markers); and triple sensor oscillator-type magnet detector probe (with magnet markers). All are designed for use in well casing incorporating slip couplings or bellows sections, although the gamma ray detector probe may also be used in unlined holes. These systems all measure vertical movement. Instruments to measure horizontal displacement due to geothermal subsidence were studied and the required instrument performance was judged to be beyond the state-of-the-art. Thus, no conceptual designs for instruments to monitor horizontal movement are included Title: Instruments for Subsurface Monitoring of Geothermal Subsidence Author: O'Rourke, J.E.

  	Citation × Citation Citation Abstract Copy Title: Environmental Monitoring for the Hot Dry Rock Geothermal Energy Development Project, Annual Report for the Period July 1975-June 1976 Author: Pettitt, Roland A. Year: 1976 For the last four years, the Los Alamos Scientific Laboratory has been investigating the feasibility demonstration of a technique for extracting geothermal energy from hot dry rock existing at moderate depths beneath the surface of the earth. In the hot dry rock (HDR) concept, a manmade geothermal reservoir would be formed by drilling an initial borehole into a region of hot rock, creating a large fracture at the bottom of the hole, then intersecting the fractured area with a second borehole. The heat contained in this underground reservoir would then be brought to the surface by the circulation of water through the system. The objectives of this environmental monitoring report are to provide a brief conceptual and historical summary of the Hot Dry Rock Geothermal Project, a brief overview of the environmental monitoring responsibilities and activities of the Los Alamos Scientific Laboratory, and descriptions of the studies, problems, and results obtained from the various monitoring programs. Included are descriptions of the work that has been done in three major monitoring areas: (1) water quality, both surface and subsurface; (2) seismicity, with a discussion of the monitoring strategy of regional, local, and close-in detection networks; and (3) climatology. The purpose of these programs is to record baseline data, define potential effects from the project activities, and determine and record any impacts that may occur. The development of the hot dry rock geothermal energy resource and associated energy extraction technology is a new field of endeavor, with no established environmental guidelines. It is doubtful if the problems encountered and solutions devised in traditional geothermal systems will apply directly to hot dry rock development. Therefore, the impacts that are encountered in this project will be of particular value in making future environmental Assessments for this type of energy resource development in other locations in different geologic settings. By the end of the reporting period, there had been no unacceptable impacts on the environment in any of the three monitoring areas Title: Environmental Monitoring for the Hot Dry Rock Geothermal Energy Development Project, Annual Report for the Period July 1975-June 1976 Author: Pettitt, Roland A.
