Downsizing, Use of Dummy and Venturi Valves Enhance Gas Lift Performance

The authors of this paper discuss the effectiveness of smaller port sizes and the use of dummy and Venturi valves to enhance gas lift performance and maximize recovery in mature offshore fields.

A mature offshore Egyptian field has entered a depletion phase. Most of its gas lift design bases were initiated during production startup and feature standardized sets of large gas lift valve port sizes with narrow spacing. Inconsistent well flow during reservoir depletion adds complications to the system. Therefore, a screenout model was created to select candidate wells for downsizing and for changing out with dummy and Venturi valves.
