Note: "Pneumatic REDA" is not a standard industry term. Based on engineering context, this guide covers the most likely interpretation: , specifically surface pneumatic panels that control downhole ESPs. If you meant a purely pneumatic downhole pump, this is covered in the "Alternative Interpretation" section at the end. Guide to Pneumatic Control Systems for REDA Electrical Submersible Pumps (ESPs) 1. Introduction REDA (now a brand of Schlumberger) is the pioneer of Electrical Submersible Pumps (ESPs). These pumps are typically driven by electric motors. However, in hazardous or remote locations, a pneumatic interface is used to control the surface electrical components—specifically the Variable Speed Drive (VSD) and motor starters.
