Available in PDF, EPUB and Kindle. Book excerpt: An in-depth study of the state of the art in Geothermal Well Log Interpretation has been made encompassing case histories, technical papers, computerized literature searches, and actual processing of geothermal wells from New Mexico, Idaho, and California. A classification scheme of geothermal reservoir types was defined which distinguishes fluid phase and temperature, lithology, geologic province, pore geometry, salinity, and fluid chemistry. Major deficiencies of Geothermal Well Log Interpretation are defined and discussed with recommendations of possible solutions or research for solutions. The Geothermal Well Log Interpretation study and report has concentrated primarily on Western US reservoirs. Geopressured geothermal reservoirs are not considered.

Book excerpt: In the petroleum industry, well logging is a well developed discipline that has matured over a fifty-year period. Compared to this, geothermal well logging is a very new field of activity. The current practice is to use the same logging equipment and the same log interpretation techniques for geothermal wells as had been used for petroleum wells. However, this approach has proven either inadequate or ineffective in most geothermal areas. The problems here are of two types: (1) those associated with logging equipment and operation, and (2) those connected with log interpretation techniques. This paper focuses on the log interpretation aspects only. 6 refs.

Book excerpt: Reservoir types are defined according to fluid phase and temperature, lithology, geologic province, pore geometry, and salinity and fluid chemistry. Improvements are needed in lithology and porosity definition, fracture detection, and thermal evaluation for more accurate interpretation. Further efforts are directed toward improving diagnostic techniques for relating rock characteristics and log response, developing petrophysical models for geothermal systems, and developing thermal evaluation techniques. The Geothermal Well Log Interpretation study and report has concentrated only on hydrothermal geothermal reservoirs. Other geothermal reservoirs (hot dry rock, geopressured, etc.) are not considered.

Book excerpt: Progress is presented on the following tasks: review of the state-of-the-art, classification of geothermal reservoir types, data acquisition, problem definition and directions for solution, and refinement of existing interpretation techniques and development of new ones. Computerized literature searches were conducted. The classification system defines five major characteristics which will qualify a potential reservoir. A catalog lists well logs currently available for study. Rock and fluid parameters needed for reservoir studies are listed. A list of matrix characteristics for rocks and minerals is given. (MHR).

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Geothermal Well Desert Peak No. B-23-1 was logged by Dresser Atlas during April/May 1979 to a total depth of 2939 m (9642 ft). A temperature of 209/sup 0/C (408/sup 0/F) was observed on the maximum thermometer run with one of the logging tools. Borehole tools rated to a maximum temperature of 204.4/sup 0/C (400/sup 0/F) were utilized for logging except for the Densilog tool, which was from the other set of borehole instruments, rated to a still higher temperature, i.e., 260/sup 0/C (500/sup 0/F). The quality of the logs recorded and the environmental effects on the log response have been considered. The log response in the unusual lithologies of igneous and metamorphic formations encountered in this well could be correlated with the drill cutting data. An empirical, statistical log interpretation approach has made it possible to obtain meaningful information on the rocks penetrated. Various crossplots/histograms of the corrected log data have been generated on the computer. These are found to provide good resolution between the lithological units in the rock sequence. The crossplotting techniques and the statistical approach were combined with the drill cutting descriptions in order to arrive at the lithological characteristics. The results of log analysis and recommendations for logging of future wells have been included.

Book excerpt: Formation evaluation is of great importance in geothermal development because of the high capital costs and the fact that successful exploration will only pay off through a subsequent decision to construct a power plant or other utilization facility. Since much formation data is available from well logging, development of new techniques of log interpretation for application to geothermal wells is called for. An analysis of potential nearterm benefits from this program and the types of formation data called for is discussed. Much useful information can be developed by adaptation of techniques used in oil and gas reservoirs, but the different demands of geothermal development from hydrocarbon production also open up new data requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Well log interpretation, the process of inferring subsurface geology from geophysical measurements made in boreholes, is the most versatile and direct means available of assessing important physical and structural reservoir properties. Historically, well logging has been developed primarily for use in oil and gas wells, and its application in a different environment such as a geothermal reservoir creates complex problems. Present geothermal development is severely hindered by lack of data. Adaptation of well logging techniques holds the promise of reducing development costs, encouraging investment, and assisting regulatory permitting. Such benefits will translate directly into lower power costs and an increased domestic energy supply. A significant acceleration of geothermal power-on-line is possible plus cost reductions through reduction of drilling failure rate, reduction of average well cost, earlier recognition of bad wells, reduced flow testing, and savings due to provision of better data for regulatory decisions. Net undiscounted benefits in 1979 dollars from improving logging and interpretation in geothermal areas can exceed half a billion dollars in slightly more than a decade, about 300 million of this should be regarded as the potential benefit of the Los Alamos Scientific Laboratory Geothermal Log Interpretation Program or similar research.
Download or read book Log Interpretation Techniques to Identify Production Zones in Geothermal Wells written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of production zones in a fractured or faulted qeotherrnal well is quantitatively difficult. Temperature and spinner surveys along with flow tests are the techniques generally used to identify and describe these fractured zones during production testing. These techniques generally do not describe the production zones in any detail and they miss or bypass potential zones of production when fractures have been closed or plugged during the drilling process. These latter zones could possibly be stimulated (hydraulic fracturing, acidizing, explosive fracturing) and brought into production if all the fracture zones could be identified and described. Interpretation techniques using wireline logs show promise in identifying and describing fractured (open and closed) zones in geothermal wells. The strategy described in this paper on two different geothermal wells (the hot dry rock well and the Surprise Valley well) used a trial and error basis to outline and define the interpretation techniques that work best in each case. Fracture zones are identified that are both open and closed and this type of information gives a better estimation of reservoir size, flow control and reservoir life (production potential) from geothermal wells.
