Latest Patents

One of his latest patents is titled "Managed pressure drilling with rig heave compensation." This innovative method involves maintaining pressure in a wellbore drilled from a floating drilling platform. The process includes pumping fluid at a determined flow rate into a drill string and measuring fluid pressure within a discharge line. The fluid discharge line's variable length corresponds to the elevation of the floating platform above the water's bottom. The wellbore pressure is determined at a selected depth or position using known parameters. Adjustments are made for changes in the fluid discharge line's length due to the platform's elevation. A backpressure system is utilized to maintain the adjusted wellbore pressure at a set point value.
