Introduction to Progressing Cavity Pumping 
Robert Constantin 
Description
A basic understanding of Coal Seam Gas (CSG) life cycle, a basic yet solid understanding of Progressing Cavity Pumping (PCP) systems, where PCP’s can provide best value in CGS applications, necessary steps to design, optimize, and operate a PCP system and pump sizing methodology to provide a successful PCP system.
Topics covered include:
- Coal Seam Gas (CSG) Overview
- Background
- Life Cycle
- Applications
- Background
- Progressing Cavity Pumping Systems
- System basic components and configuration
- PCP Advantages
- Elastomers for PCP Systems
- Surface Equipment
- PCP System Design and Application
- System basic components and configuration
- Pump Fit Considerations
- Elastomer Selection (Operating temperature, fluid compatibility, gas, time)
- Rotor/Stator Interference Fit (Swell, solids, viscosity, fluid lubricity)
- Pump Geometry (Rotor swept angles, cavity inflow index)
- Rotor Size Balanced fit Putting It All Together (Speed, pump pressure loading)
- Estimating Pump Friction Torque
- Elastomer Selection (Operating temperature, fluid compatibility, gas, time)

Who Should Attend
Target audience will be field operations and production engineers/technologists
CEUs
Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and or/ certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH). Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.
