  • Determination of representative wells to characterize subsurface regions
    Patent number: 11740386
    Abstract: Simulated wells may be selected from a subsurface representation to serve as representation of the corresponding simulated subsurface region. Spatial coverage of a simulated well for the simulated subsurface region may be determined based on extent of similarity between the simulated well and other simulated wells in the subsurface representation. The simulated wells may be selected to achieve desired spatial coverage for the simulated subsurface region and to achieve desired representation of properties of interest for the simulated subsurface region.
    Type: Grant
    Filed: July 30, 2020
    Date of Patent: August 29, 2023
    Assignee: Chevron U.S.A. Inc.
    Inventors: Fabien J. Laugier, Alicia Downard, Robert Chadwick Holmes
  • Image-comparison based analysis of subsurface representations
    Patent number: 11282269
    Abstract: 2D slices/images may be extracted from a three-dimensional volume of subsurface data. Image comparison analysis across sequential 2D slices/images may identify boundaries within the corresponding subsurface region, such as changes in style of deposition or reservoir property distribution. Identification of temporal/spatial boundaries in the subsurface region where subsurface properties change may facilitate greater understanding of the scales and controls on heterogeneity, and connectivity between different locations.

  • Characterization of subsurface regions using moving-window based analysis of unsegmented continuous data
    Patent number: 11187826
    Abstract: Unsegmented continuous subsurface data may be analyzed using one or more moving windows to characterize a subsurface region. Unsegmented continuous subsurface data may be scanned using the moving window(s). Probabilities that portions of the subsurface region include a subsurface feature may be determined based on analysis of the portions of the unsegmented continuous subsurface data within the moving window(s).
