Abstract
The fracture systems that act as conduits for fluids play an
important role in the extraction of geothermal energy in both liquid-
and vapor-dominated fields. Hydraulic fracturing is a common engineering
practice used to enhance fluid production from reservoirs with low
permeability. In hot dry rock and in vapor-dominated reservoirs that are
being depleted, it is necessary to inject water to produce steam. This
process generally requires hydraulic fracturing in advance to enhance
the recovery. Therefore, fracture imaging and characterization are
important in obtaining a better understanding of geothermal reservoirs.
In this paper, the authors present two new techniques for seismic
characterization of fracture systems. These approaches provide the means
to obtain much more detailed information about fracture systems within
geothermal reservoirs
