ABSTRACT
A new technique has been developed for determination of the formation permeability , hydraulic diffusivity, and the porosity-total compressibility product from interference well test s in geothermal reservoirs (Kutasov and Eppelbaum 2008). At present the curve-matching technique (where only values of several pressure drops are used for matching) is utilized to process fi eld data. A new method of fi eld data processing, where all measured pressure drops are utilized, is proposed. It is also shown that when high precision (resolution) pressure gauges are employed the pressure time derivative equation can be used for determination of formation hydraulic diffusivity . An example of designing an interference test is presented. A fi eld example is also presented to demonstrate the data processing procedure.
