Abraham Grader 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).

  • Representative elementary volume determination via clustering-based statistics
    Patent number: 10229344
    Abstract: An example method includes acquiring two-dimensional (2D) or three-dimensional (3D) digital images of a rock sample. The method also includes iteratively analyzing property measurements collected throughout the digital images using different subsample sizes to identify a property distribution convergence as a function of subsample size. The method also includes selecting a smallest subsample size associated with the property distribution convergence as a representative elementary area or volume for the rock sample.
    Type: Grant
    Filed: March 30, 2015
    Date of Patent: March 12, 2019
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Radompon Sungkorn, Jonas Toelke, Yaoming Mu, Carl Sisk, Abraham Grader, Naum Derzhi
  • Digital rock physics-based trend determination and usage for upscaling
    Patent number: 10223782
    Abstract: An example method includes acquiring two-dimensional (2D) or three-dimensional (3D) digital images of a rock sample. The method also includes selecting a subsample within the digital images. The method also includes deriving a trend or petrophysical property for the subsample. The method also includes applying the trend or petrophysical property to a larger-scale portion of the digital images.

  • Digital pore alteration methods and systems
    Patent number: 10198852
    Abstract: A method includes receiving images of a rock sample. The method also includes modifying a set of voxels related to one or more of the received images by applying a digital pore growing operation that changes non-pore voxels surrounding a pore space to pore voxels, wherein the digital pore growing operation is based at least in part on a predetermined dead oil estimate. The method also includes estimating a property of the rock sample based at least in part on the modified set of voxels.
