A wireline-retrievable gas lift valve is a downhole flow control device designed for installation in side-pocket mandrels within production tubing strings. These valves enable efficient gas injection into the production stream to enhance oil recovery through artificial lift. Application Highlights •Deepwater Fields: Activates low-permeability reservoirs with 40% production boost. •Sandy Wells: Erosion-resistant seats achieve 400-day sand-free operation in Shengli Field. •Marginal Fields: Payback period <6 months via low-intervention slickline operations.
