Title: Innovations of Arnold G Edwards
Introduction
Arnold G Edwards is a notable inventor based in Hockley, Texas, recognized for his contributions to the field of downhole valve apparatuses and perforating methods. With a total of 6 patents to his name, Edwards has made significant advancements in oil and gas extraction technologies.
Latest Patents
One of his latest patents is the "Hydraulically actuated downhole valve apparatus." This invention is a hydraulically controlled device that responds to changes in well annulus pressure. It is designed to be run into a well bore that intersects an oil and gas reservoir, effectively sealing off perforations in the well bore with an associated packer. The apparatus features a cylindrical housing with ports at both ends, and an operating mandrel inside. A disengaging sleeve connected to the operating mandrel allows for selective opening and closing of the ports, enabling communication of reservoir pressure through the apparatus. The activation of the disengaging sleeve and operating mandrel occurs with variations in annulus pressure.
Another significant patent is the "Anchor apparatus for a tubing and wireline conveyed method and apparatus." This innovative method involves lowering a perforator into a borehole on a tubing string. When perforating is required, a wireline is connected to the perforator, which is then disconnected from the tubing string. The perforator is lowered to the desired depth and anchored to the borehole casing or formation. This method includes a neutral release latch mechanism and an anchoring apparatus with interleaved coil springs that expand radially to set the anchor against the borehole wall.
