The Sensitivity of Geothermal Reservoir Behavior to Relative Permeability Parameters

PDF Version Also Available for Download.

Description

In the present work three problems are considered; (1) the sensitivity of {nu}{sub t} and h{sub f} to variations in the relative permeability functions; (2) the determination of {nu}{sub t} and h{sub f} from well-test data, following which a method of is suggested to use these results together with theoretical plots of k{sub rl} and k{sub rv} versus h{sub f} to deduce the general shape of the relative permeability functions is suggested; and ( 3 ) the effect of the relative permeability functions on the pressure decline and flowing enthalpy build-up during a constant rate production test. It is shown ... continued below

It is shown that the characteristic rise in the flowing enthalpy from its initial value to a stable value after a moderate time is strongly influenced by the dependence of h{sub f} on S{sub 1} (and hence k{sub rl} and k{sub rv} on S{sub 1}) .
