Abstract
The testing of geothermal wells to measure reservoir and well potential is similar in some respects to oil and gas testing; however, a number of unique problems have arisen in the geothermal case. For examples, when commonly accepted oil and gas procedures have been applied to geothermal well testing, many important parameters have been determined inaccurately or not at all. This paper presents an integrated approach to geothermal well testing which the authors believe will improve the reliability and usefulness of the data which is obtained. The objectives are to determine the key parameters in 5 major areas: (1) reservoir; (2) reservoir/wellbore interface; (3) wellbore; (4) surface equipment; and (5) reinjection ability. Some of the potential pitfalls in obtaining and interpreting this data are discussed. Finally, the paper presents several schematic diagrams of detailed field test facilities and test loops.
