Journal Article: Geology Of The Fenton Hill, New Mexico, Hot Dry Rock Site
Abstract
The Phase I prototype hot dry rock (HDR) geothermal system was developed in Precambrian basement rocks at Fenton Hill, New Mexico. Core and cuttings samples from the four deep wells indicate that the reservoir of this Phase I HDR system lies within a homogeneous biotite granodiorite body of very low permeability. Natural fractures, although present, are typically sealed with secondary minerals. The biotite granodiorite is intrusive into a heterogeneous metamorphic complex comprised of gneisses of variable composition and minor mafic schist, amphibolite, and metavolcanic rocks. The deeper part of this metamorphic section is the site of a deeper Phase II system currently under development. Differences in geology between the phase I and underlying Phase II systems will provide an opportunity for further testing of HDR development techniques.
