Latest Patents

Smith's latest patents include a "Return line mounted pump for riserless mud return system." This invention outlines systems and methods for drilling a well bore in a subsea formation from an offshore structure positioned on the water surface. The system utilizes a drill string suspended from the structure, which includes a bottom hole assembly designed to form the top hole portion of the well bore. A drilling fluid source on the offshore structure supplies drilling fluid through the drill string to the bottom hole assembly, where it exits during drilling and returns up the well bore. A suction module at the sea floor collects the drilling fluid, while a pump module on a return line, positioned below the water surface, pumps the fluid back to the offshore structure.

Another significant patent is focused on "Methods of cleaning surfaces of copper-containing materials, and methods of forming openings to copper-containing substrates." This invention describes a semiconductor processing method that cleans the surface of a copper-containing material by exposing it to a specific mixture. The process involves forming a mass over the copper substrate, etching an opening through the mass, and cleaning the base surface of the substrate with a specialized cleaning solution.
