Title: Innovations of James G Rairigh in Tubular Expansion Technologies

Introduction

James G Rairigh, located in Houston, TX, has made significant contributions to the field of tubular expansion technologies, holding a remarkable total of 22 patents. His innovative work primarily focuses on methods for selectively expanding the walls of tubular structures, particularly in wellbore applications, which has implications for the oil and gas industry.

Latest Patents

Among his latest patents, Rairigh developed innovative methods for pre-testing expansion charges, which aim at selectively expanding a wall of a tubular without causing perforation or cutting through its structure. The techniques involve determining wellbore conditions, such as hydrostatic pressure and the physical characteristics of the tubular, and reproducing these conditions at a secondary location through the use of a test tubular. His approach ensures that the test expansion charge is accurately determined and actuated to achieve radial expansion, which forms a controlled protrusion in the wall of the test tubular.

Additionally, Rairigh's patents encompass a shaped charge assembly designed for selectively expanding tubular walls. This assembly includes explosive units that provide the necessary force to create a protrusion extending outward while maintaining the integrity of the tubular structure. Such innovations are critical for enhancing the efficiency and effectiveness of operations in high-pressure environments.
