Title: Thad D Andrews: Innovator in Downhole Technology
Introduction
Thad D Andrews is a notable inventor based in Tulsa, OK (US), recognized for his contributions to downhole technology. With a total of 2 patents, he has made significant advancements in the field, particularly through his work at Baker Hughes Corporation.
Latest Patents
Thad's latest patents include the Downhole Barrier Valve and the Electric Wireline Insert Safety Valve. The Downhole Barrier Valve is a ball-type valve capable of bidirectional sealing. It features a ball that rotates on its axis to open or close with control line pressure to an actuating rod piston assembly. The design allows the ball to shift to a locked open position, surrounded by a cage that retains opposed seats. The cage is crafted from a single piece, with tangential holes drilled and tapped before being longitudinally split using a wire EDM cutting technique. Fasteners are used to rejoin the cut halves, ensuring proper spacing to the original internal dimensions. Auxiliary tools help determine the spacing of internal components, achieving the desired spring preload on the seats against the ball. Seals on the sleeves that form ball seats prevent leakage due to ball distortion at high differential pressures when the valve is closed.
The Electric Wireline Insert Safety Valve involves methods and devices for utilizing an electrically-actuated wireline insert safety valve (WLSV) within a wellbore. Power is delivered to the WLSV via inductive charging, eliminating the need for wired contact.
