  • Patent number: 10761228
    Abstract: New methods for calculating acquisition illumination are computationally less expensive in comparison with conventional methods. In one such new method, source wavefield propagations are calculated and assigned to corresponding zero-offset receivers. Further, the number of non-zero-offset receivers within the coverage of the shot at the source location is decimated. Such a method is most advantages in reverse time migration, in which all source wavefield propagations are already calculated. The receiver-side illumination for each shot can be obtained by summing up all the source-side illumination with the source located within receiver coverage. All the source-side illumination and receiver-side illumination can be summed up to get the acquisition illumination for the survey. The acquisition illumination can be used to value the acquisition system and to compensate the migration images.

  • Patent number: 10738598
    Abstract: A method for operating a drilling system that has a mud pump disposed on an earth surface and a drill string with a bottom hole assembly (BHA) in a borehole. The method involves turning the mud pump ON or OFF according to a pre-determined sequence so that the mud flow in the borehole fluctuates between high and low. The mud pulser in the bottom hole assembly senses the fluctuation in the mud flow and generates a binary signal accordingly. The mud pulser further sends the binary signal to a measurement-while-drilling (MWD) tool in the bottom hole assembly. The binary signal executes one or more firmware in the MWD tool.
