摘要
In one method, the permeabilities are obtained by correcting the geometric factor derived from combining the FRA analysis and buildup analysis. In a second method, the permeabilities are obtained by combining the spherical permeability estimated from buildup analysis and the geometric skin factor obtained from history matching the probe-pressure data. In another method, horizontal and vertical permeabilities are determined by analysis of pressure drawdown made with a single probe of circular aperture in a substantially horizontal borehole at two different walls of the borehole.
