Latest Patents
One of her latest patents is the "Noise-attenuating streamer-cable bulkhead." This invention features a plurality of streamer-cable bulkheads mounted within a streamer cable in cascade. The design is intended for radially scattering tube-wave noise from a streamer cable. Each bulkhead consists of an annular body with conical surfaces converging at a desired angle, extending outwards from both ends of the annular body. The bulkhead includes an axial hole and a plurality of off-axial holes for receiving electrical conductors and stress members. Noise traveling within the tube in a waveguide mode impinges upon the conical surfaces of the cascaded bulkheads, reflecting out of the streamer-cable jacket.
Another significant patent is the "Method for seismic lithologic modeling." This method involves seismic exploration of the subsurface of the earth. Seismic reflection data are gathered in a selected area, and this data is combined with available non-seismic data to define an initial two-dimensional lithologic model. Based on the initial model, a set of synthetic seismic data is generated. The degree of correspondence between the synthetic reflection data and the gathered seismic data is determined. The initial model parameters are systematically perturbed during a series of iterations until a desired degree of correspondence is achieved, resulting in a final lithologic model.
