The cluster arrangement is depicted in Fig. 5.22. A doublet of wells, separated by
about 10 m, services a geothermal hot water plant. The geofluid is pumped from a

depth of about 2500 m at 74 C. It passes through a trio of plate-and-frame heat ex-

changers where it heats treated water from 26 C to about 72 C. The cooled geofluid

is sent to the injection well at 28 C where it returns to the reservoir about 1.5 km from
the production spot. The heated circulating water travels through a sequence of
