Patents by Inventor Yi-Kun Yang

Yi-Kun Yang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8347959
    Abstract: A method for stimulating production of a first wellbore associated with a reservoir. The method includes determining a textural complexity of a formation in which the reservoir is located, determining an induced fracture complexity of the formation using the textural complexity, determining a first operation to perform within the formation to maintain conductivity of the formation based on the induced fracture complexity and the textural complexity, performing the first operation within the formation, and fracturing the formation to create a first plurality of fractures.
    Type: Grant
    Filed: September 3, 2008
    Date of Patent: January 8, 2013
    Assignee: TerraTek, Inc.
    Inventors: Roberto Suarez-Rivera, Sidney Green, Chaitanya Deenadayalu, David Handwerger, Yi-Kun Yang
  • Patent number: 8200465
    Abstract: A method for creating a heterogeneous earth model (HEM) of a reservoir field includes generating a group of wellsite models for a group of wellsites of the reservoir field based at least on cluster analysis and cluster tagging performed on log data of the group of wellsites, generating a reference model from the group of wellsite models, where cluster tagging errors of the group of wellsite models is minimized to obtain the reference model, constructing a contour plot of the cluster tagging errors on a cluster by cluster basis in the reservoir field, identifying at least one well location and associated core depth interval based on the contour plot for obtaining additional sampling results, and updating the reference model based on the additional sampling results to create the HEM.
