| Description/Abstract: | S>Some recent results from the Los Alamos program in which hydraulic
fracturing is used for the recovery of geothermal energy are discussed. The
location is about 4 kilometers west and south of the ring fault of the enormous
Jemez Caldera in the northcentral part of New Mexico. It is shown that
geothermal energy may be extracted from hot rock that does not contain
circulating hot water or steam and is relatively impermeable. A fluid is pumped
at high pressure into an isolated section of a wellbore. If the well is cased
the pipe in this pressurized region is perforated as it is in the petroleum
industry, so that the pressure may be applied to the rock, cracking it. A second
well is drilled a few hundred feet away from the first. Cold water is injected
through the first pipe, circulates through the crack, and hot water returns to
the surface through the second pipe. Results are described and circumstances are
discussed under which artiflcial geothermal reservoirs might be created in the
basaltic rock of Hawaii. (MCW) |
