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.
