ForeSite® Autonomous Control Increases Production by 20 STBPD, Simplifies Rod-Lift Operations, Improves Response Time

Implement autonomous control (AUC) for reciprocating rod-lift (RRL) wells to continuously optimize the well performance and reduce failures.

In close collaboration with the end users, a team of Weatherford production software and petroleum engineering consultants developed a logic that can autonomously optimize RRL well operations by controlling setpoints using ForeSite and CygNet^®.
The project was set to develop, test, and configure the automated setpoint control script.
The AUC script utilized three distinct controller types on both conventional and Rotaflex® surface units and was operated in both Recommendation Mode and Control Mode for 20 wells in pilot.
Ongoing support after deployment was provided.

The deployed AUC optimized strokes per minute (SPM) by checking controllers and ForeSite setpoints. The control logic functions mitigated under-pumping and over-pumping conditions by operating the well at peak performance conditions.
During the project, one pilot well showed pump fillage above target after the AUC made a minor speed adjustment, increasing oil production by 20 STBPD. Another well faced surface restriction, which, once removed, allowed the AUC to restore optimal performance conditions.
The customer expanded this solution to over 700 rod-lift wells that share the same controller type.
