... describes a comprehensive approach to tackle systemic failure in gas lift valves in pre-salt wells. Failure analyses in gas lift valves were performed after unexpected early failures leading to tubing-annulus communication. Understanding the root causes of this problem generates value for assets, increasing...

... Abstract Gas lift valves are an integral part of the tubing in gas lifted wells. Many operators use tubing with premium threads for these wells. Additional safety equipment, including the packer and the downhole safety valve, has been subjected to a program intended to prove its capabilities...

... mandrel diameters equal that of the CT. Additionally, the gas lift mandrels and valves must be flexible to allow spooling with the CT. Spoolable Gas Lift Valve and Mandrel Design Traditionally, downhole gas lift equipment is designed to be rigid and resist material yielding under expected service...
