Latest Patents

Mitchell's latest patents include "Subsea Fluid Pressure Regulation Systems and Methods" and "System and Method for Mitigating Pressure Drop at Subsea Pump Startup." The first patent focuses on systems and methods that quickly regulate hydraulic fluid pressure to meet demands in subsea equipment over long umbilicals. This invention features a hydraulic power unit that pumps fluid from a reservoir into a supply line, with a supply-side module that includes a circulation pump for maintaining fluid circulation. The pressure management ensures that the supply-side pressure does not exceed twice that of the demand-side module.

The second patent addresses the challenges of pressure drops during the startup of subsea pumps. It introduces fluid handling systems that mitigate the adverse effects of these pressure drops, particularly in high-pressure, low-permeability hydrocarbon reservoirs. The system employs a choke valve to control liquid flow before the pump starts, gradually adjusting the valves to optimize performance and protect reservoir integrity.
