TITLE - High-Pressure-Gas-Lift: The Critical Variables Affecting Your Maximum Outflow Potential
Since its’ introduction to the unconventional oil and gas realm in 2018, Single Point High Pressure Gas Lift (referred to as HPGL going forward) has emerged as one of the top artificial lift choices for operators in the Permian and Anadarko basins. It has become a proven technology with over 1,500 applications to date as more operators are choosing it as their primary form of artificial lift for their unconventional assets. Its ability to achieve sustained high fluid rates as well as having a high sand and gas tolerance makes it the most versatile form of artificial lift offered in today’s market.
HPGL is not a new concept having been discussed in SPE 14347. (Dickens, 1988) The concept was revitalized in SPE 187443 (Elmer, Elmer, & Harms, 2017) by which the authors of this paper emphasized its’ application for horizontal wells though at the time the needed compressor technology was not widely available to the market. This has changed as compression service companies have begun offering compressors designed to achieve the high discharge pressures needed to initially unload wells. This has led to a surge in HPGL applications as operators are looking to maintain the high output capabilities of ESPs with the benefits of gas lift.
Gas lift is a naturally flowing process; therefore, it is important to understand the pressure drop across the entire system to achieve the desirable outcome. There are many components along the flow path from reservoir to sales that affect this pressure drop. HPGL has re-emphasized the importance of Nodal Analysis, and the understanding thereof, to production engineers. Proper design and installation of each node can drastically sway your well’s performance capabilities therefore proper modeling must be conducted to ensure the desired outcome is achieved. In this paper we will demonstrate the HPGL design method used today to ensure optimal output will be achieved.
After graduating LSU in May of 2010 with a Bachelor of Science in Petroleum Engineering, Victor began his career as a lease operator for SM Energy in Shreveport, La. After 24 months of extensive field work, he moved into the role of Production Engineer where he managed SM Energy’s production assets in the East Texas Basin. He also assisted with field supervision of SM Energy’s Granite Wash completion operations and worked on several exploration teams for the SM MIDCON region. Victor joined Equal Energy in 2014 as an Operations Engineer. During his time at Equal Energy, Victor managed drilling, completion, and production operations for Equal’s Hunton Lime program. After spending two years with Equal Energy, Victor joined Casillas Operating as Production Manager in November of 2016. While at Casillas Operating, Victor managed the construction, production, facility, EHS, and midstream divisions. Victor was promoted to Vice President of Operations of CPRP Services in 2020. Victor joined Estis Compression is 2021 where he serves as subject matter expert for High Pressure Gas Lift.
Victor is a member of the Society of Petroleum Engineers, where he served as chair of the MIDCON region for the 2015-2016 year. He currently serves on the steering committee for the ALRDC Gas Lift Workshop and is an active member at his children’s school. He is currently pursuing his Masters of Energy Business from the University of Tulsa with an anticipated graduation date of December 2022.
