ICFT: An initial closed-loop flow test of the Fenton Hill Phase II HDR reservoir

Abstract

A 30-day closed-loop circulation test of the Phase I1 Hot Dry Rock reservoir at Fenton Hill, New Mexico, was conducted to determine the thermal, hydraulic, chemical, and seismic characteristics of the reservoir in preparation for a long-term energy-extraction test. loop was3successfully tested with the injection of3 37 000 m of cold water and production of 23 300 m of hot water. Up to 10 MW, was extracteg when the production flow rate reached 0.0139 m /s at 192OC. By the end of the test, the water-loss rate had decreased to 26% and a significant portion of the injected water was recovered; 20% during subsequent venting. hydraulic, geochemical, tracer, and seismic data suggests the fractured volume of the reservoir was growing throughout the test. The Phase I1 heat-extraction 66% during the test and an additional Analysis of thermal, SUMMARY The Initial Closed-Loop Flow Test (ICFT), Experiment 2067, was The ICFT designed as a precursor to a long-term energy-extraction experiment in the Phase I1 Hot Dry Rock (HDR) reservoir at Fenton Hill. successfully evaluated the Phase I1 heat-extraction loop from May 19 through June 18, 1986. EE-3A and hot water was produced at EE-2, cooled, and reinjected (Hendron, 1987).

“…The second stage will be critical in execution of expected capacity testing drills and depends on the quality of feasibility study may find suitable sponsor. The third stage is more standard, but successful and timely execution of the construction of GPP and to be in the budget will have also influence to final result [9].…”
