Title: Innovations by John E Kahil in Subterranean Well Technology

Introduction

John E Kahil is an accomplished inventor based in Houston, TX (US), known for his significant contributions to the field of subterranean well technology. With a total of 4 patents to his name, Kahil has developed innovative tools and methods that enhance the efficiency and safety of oil and gas extraction processes.

Latest Patents

Kahil's latest patents include an "Apparatus for servicing tubular strings in subterranean wells" and a "Method and apparatus for measuring defects in ferromagnetic elements." The tubing trip tool described in the first patent is designed to determine the extent of defects in tubular sections of a continuous tubing string used in subterranean oil and gas wells. This tool is mounted on a surface rig surrounding the tubing string, allowing for magnetic detection of defects during tubing removal from the well bore. The tool features a segmented expandable detector head that measures average wall thickness and identifies local and axially extending defects. It is spring-loaded and pneumatically actuated, with coupling detectors to count tubing sections and detect obstructions, thereby preventing damage to the detector head.

The second patent outlines a method and apparatus for assessing defects in ferromagnetic tubular elements. This technology measures average wall thickness, local defects such as corrosion pitting, and axial defects like sucker rod wear during the removal of tubing from the well. It also measures tubing velocity and detects couplings between tubing sections to specify the axial location of defects, providing a comprehensive profile of the overall string's condition.
