Title: Innovations by John Haynes in Oil and Gas Inspection Technologies.

Introduction

John Haynes is an accomplished inventor based in Houston, Texas, known for his contributions to the field of oil and gas inspection technologies. With a total of two patents to his name, Haynes has developed innovative solutions that enhance the safety and efficiency of well tubular inspections.

Latest Patents

One of Haynes' latest patents is an "Oil and gas well tubular inspection system using Hall effect sensors." This inspection system is designed to detect flaws in oil and gas well borehole ferromagnetic tubulars. The device operates by saturating the tubular wall with magnetic flux. When flaws are present, flux leakage occurs, and the magnitude of this leakage is measured using Hall effect sensors within the device. The measurements are then correlated to the amount of ferromagnetic material loss due to the flaw. Additionally, the system measures eddy currents induced in the wall, which, when combined with Hall effect sensor data, helps define the location and geometric shape of the flaw.

Another significant invention by Haynes is the "Ultrasonic thickness gauge for pipe." This compact ultrasonic tester features rotating sensors, with the processor rotating alongside them. The output signal from the processor is transmitted through slip rings, rather than from the sensors directly. The device includes a spraying system that works with rollers to apply a film on the outer pipe surface, ensuring good contact for accurate results. A floating shoe holds each sensor against the pipe wall, allowing the machine to accommodate different pipe diameters. By controlling the pipe's speed and the sensors' rotational speed, the system guarantees 100 percent coverage of the pipe wall. This compact machine can be installed behind existing electromagnetic and gamma testers without requiring major modifications to pipe-testing facilities.
