Paper: Using Varible Frequency Drives on Rod Pumping Installations

Variable Frequency Drive (VFD) technology has been employed in a wide variety of applications in many industries in recent years. Application of VFD to the rod pumping system has allowed pumping speed to be adjusted in real time by the POC, eliminated sheave changes as well conditions change, reduced power consumption, and allowed continuous pumping of wells producing formation solids. This paper will review the installation, operation, benefits and economics of installations on new and existing wells at several locations in West Texas operated by BP America
