Gas Compression System For Wellbore Injection, and Method For Optimizing Gas Injection

摘要

A gas compression optimization system is provided. The optimization system is designed to control a rate of gas injection in connection with a gas lift system in a wellbore. The system includes a string of production tubing, and an annular region around the production tubing. The system also comprises a production line at the surface. The system also includes a pressure transducer that is configured to determine a differential pressure across an orifice plate placed along the production line. The system additionally includes a gas injection line. The gas injection line is at the surface, and is configured to inject a compressible fluid into the annular region. The system additionally includes a controller. The controller is configured to control the injection of the compressible fluid into the annular region in response to the differential pressure signals. A method for optimizing gas injection rate into a wellbore in support of a gas lift operation also provided herein.
