Title: Randy Royce Rowland and Low-Temperature Sub-Surface Safety Valve Innovation.

Introduction

Randy Royce Rowland is an inventor associated with Rosharon, Texas, and Schlumberger Technology Corporation. His patent work addresses the challenges that low-temperature downhole environments pose to sub-surface safety valves.

Latest Patents

Rowland is credited with 1 patent, titled “Insert Sub-Surface Safety Valve (SSSV) for Use in Cold Temperature.” The invention concerns a safety valve designed for low-temperature downhole conditions, which may arise when fluids such as carbon dioxide are injected. Such conditions can damage elastomer seals and compromise valve performance.

The disclosed design uses non-elastomeric seals and metal-to-metal sealing between components. It also employs metal-to-metal threads between body joints, avoiding the need for elastomers in those threaded connections. These features are intended to reduce fatigue and seal damage in cold environments.

Career Highlights

Rowland’s documented patent contribution focuses on improving the durability of sub-surface safety valves under demanding downhole conditions. His work reflects an engineering approach that replaces vulnerable elastomer-dependent connections with metal-to-metal alternatives.

Collaborations

Rowland is associated with Schlumberger Technology Corporation. Garis Mccutcheon is identified as a coworker.

Conclusion

Randy Royce Rowland’s patent describes a sub-surface safety valve designed to withstand low-temperature downhole environments by using non-elastomeric seals and metal-to-metal connections.
