With a total of three patents to his name, Jaynes has developed innovative tools and methods that enhance the efficiency and safety of oil and gas extraction processes.

Latest Patents

One of Jaynes' latest patents is an "Apparatus for servicing tubular strings in subterranean wells." This tubing trip tool is designed to determine the extent of defects in tubular sections of a continuous tubing string used in subterranean oil and gas wells. The tool is mounted on a surface rig surrounding the tubing string, allowing for magnetic detection of defects during the tubing's removal from the well bore. The segmented expandable detector head is equipped with elements that measure average wall thickness and identify local and axially extending defects. The head is spring-loaded and pneumatically actuated, with coupling detectors at the ends to count tubing sections and detect obstructions, thereby preventing damage to the detector head.

Another notable patent is the "Method and apparatus for measuring defects in ferromagnetic elements." This invention focuses on determining the extent of defects in ferromagnetic tubular elements used in oil and gas wells. The tubing trip tool measures average wall thickness, local defects such as corrosion pitting, and axial defects like sucker rod wear during the tubing's removal. It also measures tubing velocity and detects couplings between tubing sections to specify the axial location of defects and provide a comprehensive profile of the overall string's condition. The method employs a saturating magnetic field and a fluctuating magnetic field to quantify defects in the tubing.
