Designing the right artificial-lift system to operate with a steady state flow of gas is challenging enough. But the challenges only multiply during intermittent gas production, or slugging. If your lift system is not properly selected and designed to handle gas, you can expect an expensive well intervention to replace the system with another type of lift.
Our lift experts approach gas control with a three-phase strategy aimed at minimizing pump damage and optimizing performance.
Phase 1 – Separate and Divert
Our primary control solution focuses on separating the bulk of gas from the production stream and diverting it to the annulus before it can enter the pump. We achieve this two ways:
Phase 2 – Robust Pump Designs
Apergy Artificial Lift's division designs pumping solutions that effectively handle certain volumes of gas, without significant losses of operational efficiency.
None of our products are simply off-the-shelf, one-size-fits-all solutions. Our product specialists work with you to first understand your well’s unique gas challenges, and then carefully design the right gas control solution to extend the productive life of the asset.
Phase 3 – Control
Apergy Artificial Lift's division provides industry-leading control systems that sense changes to gas content in the production stream and then make real-time changes to the lift system’s operation. For example, our Theta Oilfield Services XSPOC diagnostic software suggests changes to rod pump speed as free gas volumes change, and gives the user the opportunity to change stroke speed remotely. For ESPs, our LOOKOUT Monitoring system uses real-time production data to give an early warning of gas locking, allowing you to quickly change parameters such as ESP rotational speed to accommodate.
