  • Methods and systems for evaluating and treating previously-fractured subterranean formations
    Patent number: 7580796
    Abstract: Methods, computer programs, and systems for evaluating and treating previously-fractured subterranean formations are provided. An example method includes, for one or more of the one or more layers, determining whether there are one or more existing fractures in the layer. The method further includes, for one or more of the one or more existing fractures, measuring one or more parameters of the existing fracture and determining conductivity damage to the existing fracture, based, at least in part, on one or more of the one or more measured parameters of the existing fracture. The method further includes selecting one or more remediative actions for the existing fracture, based, at least in part, on the conductivity damage.
    Type: Grant

    Date of Patent: August 25, 2009
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Mohamed Y. Soliman, Loyd E. East, Neil A. Stegent, Joseph Ansah

  • Methods and systems for using wavelet analysis in subterranean applications
    Patent number: 6978211
    Abstract: The present invention provides methods of monitoring the injection of a fluid into a subterranean formation. The present invention also provides a method of fracturing a subterranean formation. All methods feature the use of a wavelet transform of data generated by the subterranean injection process.
