The next generation of artificial lift engineers will have much better tools and have different understandings of how their knowledge interacts with the science of artificial lift. There is ample opportunity to explore and improve how each of those methods is practiced.
“Some would suggest that artificial lift is at its zenith, but it only appears that way when looking at the methods from the perspective of current technology. “There are now several established methods of artificial lift, each with its own history, body of knowledge, and practices,” he said. The goal has not yet been met, but if you really want to know what happens in gas lift, understanding the real behavior of gas lift valves is the first step. “Gas lift has been practiced as an art since its first use,” Decker said, “and I attempted to push the boundaries into the realm of science.

His company also developed the Dynalift gas lift simulator that is currently marketed by Weatherford. His company, Decker Technology, manufactures an Automatic Valve Testing tool that verifies the quality of valves before sending them to the field. While Herald Winkler pioneered the concept of gas lift valve testing, Decker took it mainstream and integrated the use of valve performance in gas lift design and trouble shooting. These VPC correlations were distributed to all VPC members and have now been incorporated into WinGLUE, SNAP, PROSPER, WellFlo, PipeSim, and OLGA, as well as into member companies’ inhouse software. During his tenure at the consortium, he personally tested and developed custom correlations for 59 different commercially available gas lift valves and 216 valve-port size combinations. In 1997, he founded the Valve Performance Clearinghouse (VPC) consortium and served as administrator until 2014, when he handed over administration to Louisiana State University. Upon his retirement from Otis in 1993, Decker formed his consulting business, Decker Technology. After earning his BS degree in 1971 from Michigan State University, he worked on gas lift projects around the world, first with Teledyne Merla, then Otis Engineering.

He has served on numerous API and ISO committees writing standards for gas lift equipment design and testing, and he has written numerous SPE papers on gas lift valve performance. The comparison between them showed that the gas lift technique gave the highest production rate at different reservoir pressure and water cut.Ken Decker has practiced gas lift for more than 30 years and is considered an expert in the use of gas lift valve performance, design, and troubleshooting. The results also showed that gas lift system contributed to increase production rate to (3805) STB/D at water cut 60% and ESP raised the production rate to 3087 STB/D at water cut 60%. The result showed that Gas lift system contributed to increase production rate to (3198) STB/D at reservoir pressure equal to 2750 psi, while using the ESP system improved oil production rate to (2800) STB/D at reservoir pressure 2750 psi.
Therefore, the artificial lift techniques were applied to increase the oil production rate. The production rate was decreased to 1917 STB/D when reservoir pressure reached to 2750 psi, and flow rate decreased to 1210 at water cut 60%.
The effect of decreasing reservoir pressure and increasing water cut on production rate has been studied through the evaluation of the well performance.

Firstly, the mathematical model has been built and validation has been done using PIPESIM software in order to select the best correlation (Duns & Ros correlation) for the pressure gradient calculation in the wellbore. Electrical submersible pump (ESP) and gas lift techniques were applied to one well (NS-Y) in the studied reservoir. The possibility of improving the oil production rate for Mishrif formation in Nasiriyah oil field, located in Thi-Qar Governorate – southern province of Iraq, proposed in this paper.
