What is a Gas Lift Curve? ➡ In short, it shows our expected oil rate at all gas lift injection rates! 😢 In the past, we had to manually sensitize the new BHP for one specific gas lift rate, then see where that rate lands along our IPR curve. Repeat the process for a different gas lift rate. It was brutal! ⭐ Now, we can instantly see our expected oil rate at any gas lift rate! Even evaluate lower casing pressures to predict opening a deeper gas lift valve. As you can see, there's more then 1 route to increase oil production with gas lift. 🛣 Video Case Study: https://lnkd.in/gtcTNp37 💌 Contact us to learn more. #nodal #productionengineering #productionoptimization whitson Curtis Hays Whitson Ilina Yusra Markus Blytt Markus Hays Nielsen Henrik Lia Bilal Younus Sissel Øksnevad Martinsen Sayyed Ahmad Alavian Stian Mydland Kameshwar Singh Hamna Zafar Mathias Lia Carlsen John Ratulowski Milan Stanko Mohamad Majzoub Dahouk Lavrans Blytt Jason Hu Barry Ruddick Leslie Thompson Edvard Schwabe Jortveit Venkata Bala Krishnateja Chavali Arnaud Hoffmann Graham Helfrick Henrik Berg Nemanja Dunić Kjetil Lorentzen Ana Proaño

Thanks for sharing some of the capabilities of the software especially about gas lift well response. It is impressive to have such flexible features in web-based Nodal Analysis software. What I want to get a clear understanding about is the well response to gas lift injection based on valves opening and closing pressures as demonstrated in the tutorial video. I think it is better to sensitize on injection gas not the casing pressure to reflect the actual or the real well response. From what I understand, we are here assuming a fixed point of injection at higher casing pressures for shallower point of injection, and lower casing pressures for injection through deeper valves which have lower surface opening pressure. For each casing pressure case, and by assuming a fixed depth of injection, we generate the well production rate response to injection gas rates. In real-case scenarios, it is the case that we inject through two or more valves concurrently, if the tubing pressure gradients allow to uncover deeper valves.

And here is another way to use Surface Jet Pump supporting gas lifted wells.

5moUsually, the sensitivity on casing pressures is a preliminary study performed before the gas lift design, what is normally called a gas lift response. The actual response is reversed compared with what is shown in the above picture, because increasing casing pressure allows injecting deeper in the well and results in higher production rates. Of course there are some assumptions like fixed pressure difference across the calculated point of injection and estimating the number of unloading valves for surface closing or opening pressure reduction or safety factors. The final depth of point of injection, injection gas rate, and well production rate is the final results of the mandrel spacing procedures (Gas lift design).
