Title: Innovations by Steven C. Speegle
Introduction
Steven C. Speegle is a notable inventor based in Flower Mound, TX (US). He has made significant contributions to the field of engineering, particularly in well safety technology. With a total of 3 patents, his work showcases innovative solutions for the oil and gas industry.
Latest Patents
One of his latest patents is the Well Safety Valve. This invention features a retrievable well safety valve designed for a cased well system. It includes a tubing string, a dual packer downhole around the tubing sealing with the casing, and a submersible pump located below the packer. The safety valve effectively controls the flow of pumped fluids through the tubing to the surface while directing gas flow into the casing annulus above the packer. When the safety valve is properly positioned in cooperating tubing nipples above the packer, it creates separate central annular flow passages for both pumped fluids and gas. A ball valve within the central flow passage regulates the flow of pumped fluids, while an annular valve works in conjunction with the ball valve to manage gas flow from below the packer. This design ensures that the flow of fluids and gas remains separate, preventing any unwanted mixing.
Another significant patent is the Equalizing Means for Well Tools. This invention provides a pressure equalizing mechanism for well tools that feature a tubular housing and an operator tube that moves longitudinally within it. The design includes a valved bypass passage in the housing and a shoulder on the operator tube that engages and opens the valve of the bypass passage upon movement. The equalizing mechanism also incorporates a pair of seal rings that maintain a bubble-tight integrity, even if the valve in the bypass passage does not seal perfectly.
