Latest Patents

One of his latest patents is titled "Domain freezing in joint inversion." This method involves estimating geological properties in a subsurface region using multiple types of geophysical data. An initial physical properties model is constructed, where some parameters in the model are frozen. Portions of the model wave number and spatial domains, as well as the data frequency and time domains, can also be frozen. A joint inversion of the multiple data types is then performed to update the model only for the portions that are not frozen. The converged model from this inversion serves as a new starting model, and the process can be repeated, unfreezing more parameters and data each time until the desired spatial and parameter resolution is achieved.

Another significant patent is "Adaptive weighting of geophysical data types in joint inversion." This method focuses on adaptive weighting of geophysical data types during iterative joint inversion to enhance convergence speed and help escape local minima of the penalty function. Two or more geophysical data sets representing a region of interest are obtained and jointly inverted to infer models of the physical properties affecting the data types used. The misfit for each data type is a weighted term in the penalty function. The invention involves modifying the weights as the iteration cycles progress when the iteration convergence criteria are satisfied, ensuring that they remain satisfied with the modified penalty function.
