Exploration Basis
An additional closed-loop flow test was conducted in the Phase II reservoir from May 10 to July 14, 1995 to investigate and compare changes in heat transfer and reservoir volume to those measured during previous circulation tests. Furthermore, chemical tracer tests were performed in an effort to improve understanding of the spatial characteristics of reservoir conduits, especially those that constitute major fluid flow paths.
Over time, the longer residence-time paths account for progressively more of the total flow, and flow paths through the reservoir volume become more diffuse.
