Heat and mass transfer in a fault‐controlled geothermal reservoir charged at constant pressure

“…Modeling efforts, Riney et al [27] found that the vertical reservoir permeabilities of about 0.3-0.5 md and horizontal reservoir permeabil~ ities of about 90 md were necessa~y to match the observed field data.…”

“…Riney and Pritchett [28] studied the effect of introduction of a fault model on the subsurface isotherms and the surface heat flow patterns in the East Mesa field, using a similar assumption. In addition, the Boussinesq approximation is invoked.…”
