Latest Patents
One of her latest patents is a device for assembling jacketed lengths of pipe base well screens. This device facilitates the assembly of lengths of jacketed pipe base well screens in wells, utilizing manual or power tongs that have a greater vertical height than the blank pipe base end sections of the screens. The device features a pair of pivoted semicylindrical portions with compressible rubber liners at their ends, which overlie the screen jacket. The jaws at the ends of the device overlie the blank pipe, and a removable pin locks the screen jacket end at a fixed outer diameter. The design allows for a reduction in diameter as force from a set of tongs compresses the device against a blank section of pipe.
Another significant patent is the expandable packer assembly for sealing a well screen to a casing. This improved packer assembly addresses contamination issues associated with expandable lead packers and the abrasion of self-sealing packers, which can become ineffective before reaching their intended depth. The assembly consists of a pair of annular end members that are threaded to the well screen and the drill stem, joined by a compressible, tubular metal portion. When the well screen reaches its intended depth, a swedge dropped against the upper end member compresses the ends of the tubular metal portion, allowing the intermediate portion to expand and create a seal with the casing. The seal can be further enhanced by applying rings or layers of elastomeric material to the tubular metal portion.
