How it improves performance
OM-21R-B Barrier Series single-point-injection orifice gas lift valves are used for continuous-flow gas lift production applications. Based on field-proven technology, these 1-in-OD retrievable valves feature a barrier-qualified back-check system, incorporating a metal-to-metal seal that has been developed and tested to meet API Spec 19G2 V0 standards. The back-check system has enhanced geometry to minimize erosion while maintaining dart stability during high-rate operations.
An integral choke controls flows through the normally open gas lift valve into the production conduit. The seal stack has been tested beyond API specifications to meet zero-bubble requirements.
The increased performance and reliability enabled by these features permit installing the OM-21R-B gas lift valve as a well barrier element.
How it works
For standard operation, the valve is installed in a side pocket mandrel. Injected high-pressure gas enters the mandrel inlet and the OM-21R-B valve through the ports between the seal stacks and travels across the orifice, down to the back-check system, and into the production conduit.
