A Review of Intermittent Gas Lift and Fallback Factor Modeling Objective/Scope At some point in the producing life of a gas lifted well, it is recommended to switch from continuous gas lift to some type of intermittent gas lift. Various methods such intermittent gas lift with a downhole pilot valve, gas-assisted plunger lift with a […]
Industry Pursuit of API 19G2 V0 Validation Abstract The American Petroleum Institute (API) Specification 19G2 sets forth the standards for the validation and functional testing of gas lift flow control devices. Specification design validation grade V0 represents the highest level of testing rigor to validate flow control devices for use in severe conditions or simply […]
Deep Water Gulf of Mexico – Challenging Hi Angle Subsea Gas Lift Valve Intervention Abstract This paper presents the technology utilized to efficiently replace a leaking Gas Lift Valve (GLV). The technical challenge was to replace the GLV, at short notice (due to the operating window), allow the Kickover Tool (KOT) to pass a minimum […]
Using AI to Address Hidden Inefficiencies in Gas-Lifted Wells Abstract: Important innovations enable us to do something faster and then do the impossible. Gas-lifted wells are challenging to manage because they hide their inefficiencies. Gas-lifted wells typically continue to produce, even if they have problems that hurt production. Finding the underperforming wells in a field […]
Disruptive S-Curves for Surface Controlled Gas Lift and ESPs Abstract: First, I am going to talk about some science related to innovation and market acceptance trends in new technologies. Most are familiar with the S-Curve. Maybe some are familiar with the disruption curve. The next step is the interactions between these in technology ecosystems. I […]
Unlocking Future Well Productivity: Insights from Historical Data-Driven Analysis of an Intelligent Surface-Controlled Gas Lift Technology Abstract: This abstract compares the performance of a surface-controlled gas lift system with conventional gas lift technologies. The remote-control system provides operators with the capability to precisely calculate the necessary quantity of injected gas to achieve a specific oil […]
Application of Shear Gas Lift Valves in the Pre-Salt Buzios Field Abstract: Since the beginning of pre-salt oil production, Petrobras has identified over 25 cases of failure in gas lift valves, characterized by unwanted flow from tubing to annulus. Out of these, at least 14 cases have required a rig intervention to replace the damaged […]
The Success Story of High Pressure Gas Lift In Onshore Unconventional Production Abstract: Scope/Objective This presentation explores an artificial lift method whose use is rapidly expanding in onshore North American unconventional reservoirs. High Pressure Gas Lift (HPGL) as it is known, is reviewed both from a historical and technical perspective. The factors behind HPGLs success […]
First Deployment in Middle East of Digital Gas Lift in Dual String Offshore Well Abstract: Objective/Scope: Gas lift is one of the most crucial components for achieving and maintaining production targets for ADNOC Offshore assets. One major factor for this is the utilization of dual completions, whereby two production zones can be produced via a […]
Production Stabilization In Wells With Downward Inclined Flowlines Through Seafloor Gas Lift Abstract: Subsea bathymetry may play an important role in production flow stability. This is the case of a well located 14 km away from the production unit, demanding a long downward tie-back. Given such conditions, it was necessary to apply a solution to […]
