... valves. Furthermore, even obtaining training examples for event diagnosis is challenging due to the rarity of some gas lift valve problems. In gas lift well surveillance, it is essential to generate real-time results to allow a swift response by an engineer to prevent harmful consequences of gas lift...

... this alternative approach effectively controlled scale deposition such that the production systems was protected and the production benefits included increased reliability of gas lift valves, cessation of any tubing acid washes and enhancing production. The economic value added and reduction in risk to personnel...

... intervention would be required to remove the dummy valves and install the live gas lift string. This can be a long, cumbersome process that can damage existing infrastructure and delay production while new live valves are installed. This paper presents a smart gas lift valve with disintegrable nanostructured...

... degenerate into huge oscillations in flow parameters. Tubing Heading. Gilbert and Grupping et al. were the first to describe the mechanisms by which these unstable conditions are generated. In many wells, the operating gas lift valve is simply an orifice valve and operates in the subcritical flow regime...

... Abstract This paper provides a status report of ARCO's use of thin metal films to improve the operability of gas lift valves. Thin metal films have been used to minimize the problems associated with performance degradation of the gas lift valves due to scale accumulation and sticking...

... Abstract BP Exploration and Nowcam Services have recompleted a well in the Western Operating Area (WOA) of the Prudhoe Bay Unit with a spoolable coiled tubing gas lifted completion. This completion is unique in that gas lift valves are inside the coiled tubing. Their design allows them to bend...
