  • Publication number: 20190302309
    Abstract: Geologic modeling methods and systems disclosed herein employ fault face parameterization to constrain and improve the transformation of a faulted physical space geologic model into an unfaulted depositional space geologic model. An illustrative embodiment includes: associating a seismic image with each face of at least one fault in a subsurface region; determining a correspondence map between the seismic images for said at least one fault; parameterizing the faces using the correspondence map to match parameter value assignments for corresponding portions of the faces; creating a displacement map that draws together matching parameter values to align the corresponding portions of the faces; applying the displacement map to the geologic model to create a design space model; modifying the design space model; applying the displacement map in reverse to the modified design space model to obtain a modified geologic model; and outputting the modified geologic model.

  • Patent number: 9645270
    Abstract: Method for mitigating coherent noise and seismic data using an adaptively varying filter. The strongest and most coherent pattern (53), generally associated with the geology, is adaptively removed (56) from the original seismic data, producing an intermediate product that consists predominantly of noise. These noise data are then removed from the original input data (57) to produce a significantly more interpretable seismic volume.
