Latest Patents
One of Xu Ji's latest patents is titled "Automatic tying structure maps of subsurface horizons to well-derived orientation information." This invention discloses methods for automatically integrating subsurface structural maps with strike and dip information measured in subsurface wells. The method involves obtaining a seismic image volume for a subsurface region of interest and a well log for each of a plurality of wellbores penetrating that region. It further includes determining a seismic map of a geological surface from the seismic image volume, which comprises an estimated depth and an estimated vector normal to the seismic map at various horizontal locations. The invention also details how to determine intersection points for each wellbore with the geological surface and construct a subsurface map by solving a constrained optimization problem based on a cost function.
Another notable patent by Xu Ji is focused on "Systems and methods for detecting seismic discontinuities by coherence estimation." This method generates a geophysical image of a subsurface region by defining a computational sub-volume that includes a predetermined number of seismic traces and samples. It estimates coherence between the traces by performing a variance sum of the samples and assigns the estimated coherence to a location in the geophysical image.
