Detecting and Locating Tubing-Casing Leaks from Analysis and Acoustic Fluid Level Records Abstract: The efficiency of most artificial lift systems is reduced significantly whenever the tubing and the casing annulus are in communication due to the presence of unwanted holes or leaks developed in some of the hardware used in the completion. Detection of the […]
Downhole Pressure and Temperature Survey Analysis for Intermittent Gas Lift Wells: A Case Study in Assam Arakan Basin Abstract: Gas lift is the major artificial lift method for the wells of brownfields in the Assam Arakan Basin. It is the best suited method for maintaining and extending the current production rate of the fields. In […]

Real-Time Surveillance System for Gas Lift Troubleshooting Abstract: Gas lift surveillance and optimization pose significant challenges to oil and gas operations, particularly in monitoring a large number of wells. Manual efforts often result in oversight, delayed responses, and potential production losses due to suboptimal gas lift operations. Real-time systems, capable of automating routine gas lift […]
Gas Lift Optimization Strategies for Enhanced Productivity in Ageing Brown Fields Abstract: The introduction and optimization of gas lift systems in oil wells is a crucial process that aims to enhance the recovery of hydrocarbons and extend the life of a well. When brown fields and assets in late life are considered within the context […]
Erosion Testing of Conventional Gas Lift Check Valves for Unconventional Applications Abstract: Onshore tight oil production has led to a renaissance for conventional gas lift equipment. After years of customer and supplier focus on side pocket mandrels and their associated flow control devices, tubing-deployed conventional mandrels and valves are back in style. But are yesterday’s […]
Learnings from the Design and Testng of a New Surface-Controlled Gas Lift Valve Abstract: Petroleum Technology Corporation (PTC) and Emerson worked together to develop a surface-controlled gas lift valve (SCGLV). This SCGLV uses existing technology from both companies. Emerson uses their IDN network and downhole control modules used for gauges to power and operate the […]
