  • Well testing using multiple pressure measurements
    Patent number: 6675892
    Abstract: A technique includes measuring a first pressure of well fluid in a first region. The well fluid is produced from a formation into the first region. A second pressure of well fluid is measured in a second region. The second region is isolated from the first region, and the well fluid in the second region is in communication with the formation characteristics (skin, horizontal permeability or vertical permeability, as examples) of the formation is determined from the first and second measured pressures.
    Type: Grant
    Filed: June 13, 2002
    Date of Patent: January 13, 2004
    Assignee: Schlumberger Technology Corporation
