  • Diagnosis of formation characteristics in wells
    Patent number: 7874357
    Abstract: A technique for estimating the permeability profile of a well includes generating a well and formation model. The technique includes producing the well so that hydrocarbons flow from the formation and through the well. The technique includes measuring pressure at a plurality of points along at least a portion of the well without an intervention in the well and estimating a permeability profile along the portion of the well by use of the plurality of pressure measurements.
    Type: Grant
    Filed: February 27, 2004
    Date of Patent: January 25, 2011
    Assignee: Schlumberger Technology Corporation
    Inventors: Younes Jalali, Yannong Dong, Huanwen Cui, Shekhar Sinha, Rintu Kalita
