Title: Gregory Campbell: Innovator in Tubing Fatigue Assessment

Introduction

Gregory Campbell is a notable inventor based in Katy, TX (US), recognized for his contributions to the field of tubing fatigue assessment. With a total of 3 patents, Campbell has developed innovative techniques that enhance the safety and efficiency of wellbore operations.

Latest Patents

One of Campbell's latest patents focuses on "Tracking and estimating tubing fatigue in cycles to failure considering non-destructive evaluation of tubing defects." This technique facilitates tracking and assessing the fatigue life of a tubing string by estimating cycles to failure during wellbore operations. The process begins with determining the initial fatigue life of the tubing string. A sensing device, such as a magnetic flux leakage (MFL) device, is utilized to monitor the tubing string. When the sensing device detects an anomaly, such as a new defect, a revised fatigue life of the tubing string is calculated based on the detected change. This new fatigue life is crucial for estimating the tubing's fatigue life in terms of cycles to failure.
