  • Publication number: 20070157719
    Abstract: In one method, the permeabilities are obtained by correcting the geometric factor derived from combining the FRA analysis and buildup analysis.
    Type: Application
    Filed: January 22, 2007
    Publication date: July 12, 2007
    Applicant: BAKER HUGHES INCORPORATED
    Inventors: James Sheng, Daniel Georgi
  • Publication number: 20060042370
    Abstract: 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 other methods, horizontal and vertical permeabilities are determined by analysis of pressure drawdown made with a single probe of circular aperture in a deviated borehole at two different walls of the borehole.

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.
