  • Determining an elastic model for a geologic region
    Patent number: 10977396
    Abstract: A technique includes determining at least one impulse response of a modeling and migration of at least one point scatterer in a target structure and based at least in part on the impulse response(s) and a reflection amplitude image, determining a model for at least part of the target structure.
    Type: Grant
    Filed: August 20, 2012
    Date of Patent: April 13, 2021
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Stewart Archer, Robin Fletcher, Weijian Mao, David Nichols
  • Spectrum Splitting
    Publication number: 20200183030
    Abstract: Spatial sampling is a key factor in determining acquisition parameters for seismic surveys. Acquiring the data to meet spatial sampling requirements for low, mid and high frequencies, by acquiring coarse, medium and fine acquisition grids respectively and layering these during processing, can result in reduced cost and/or higher quality surveys.
    Type: Application
    Filed: December 11, 2018
