Abstract
From 1979 through 1984 the U.S. Department of Energy (DOE) sponsored t en stimulation experiments in hydrothermal geothermal wells. The work included literature reviews, laboratory studies, field tests of hydraulic fractures and acidization treatments, explosive stimulation, and high energy gas fracturing. Hydraulic fractures can be economic in sedimentary rock with substantial matrix permeability. But what are now seen as the most typical hydrothermal wells, in naturally fractured reservoir zones, were not converted to useful wells in these experiments.
