A research hot dry rock (HDR) geothermal energy reservoir is currently under development in the Carnmenellis granite in Cornwall (UK) at a depth of ca 2000 m. This study details the conduct, analysis, and interpretation of hydraulic tests using low to medium pressures and flow rates. These tests allowed an evaluation of the in situ hydraulic parameters relavent to initial water storage and long term leakage. Tests were analyzed using both diffusion theory and an explicit coupled hydraulic/mechanical computer code. The computer model was able to similate several cycles of injection and shut-in at progressively higher pressures and flow rates with a single set of variables. 18 references.
