Title: Richard W Luhning: Innovator in Sand Exclusion Technology

Introduction

Richard W Luhning is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of oil and gas technology, particularly with his innovative approach to sand exclusion in wellbores. His work has implications for improving the efficiency and effectiveness of drilling operations.

Latest Patents

Luhning holds a patent for a "Sand exclusion liner and method of using the same." This invention modifies a conventional screened liner to enable fluid circulation through its length while working it toward a landing position in a horizontal wellbore. At the surface, a sleeve of heat-liquifiable sealant, such as wax or tar, is formed internally in each perforated liner joint to blind the liner openings. The design allows for a central longitudinal bore to be formed through the sleeve, enabling circulation through the entire length of the liner to remove sand blockages without reversing fluid flow through the liner openings. Once the liner is in place, the sealant can be removed by circulating steam past it to liquefy it.
