Abstract
Studies of heat extraction efficiencies from fracture stimulated and low productivity hydrothermal resources, which will aid in the raid growth of geothermal energy utilization, are an ongoing part of the Stanford Geothermal Program. Recent experiments have been run to compare both specific energy extractions and energy extraction fractions from a sand packed rock loading with lower porosity and permeability to these values in the original high porosity, high permeability rock loadings. The data are useful in extrapolating the reservoir model results to large scale geothermal reservoirs. The result for two experiments produced by the in place boiling process show improved energy recovery with insignificant impedance of natural convection and cooling of the rock.
