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