For heavy oil and extra heavy oil the use of positive displacement pumps which are able to handle fluids with high viscosity are required. The well streams are a combination of crude oil, water, gas and sand. For each region and reservoir, the proportions of the oil, water, gas and sand will vary. For economic, environment and facilities management perspectives, it can be a distinct advantage to transfer the complete well stream to gathering and processing facilities rather than separate at the well site. The selected pump system should be reliable, safe and able to handle the variations in fluid composition and process conditions. The Pro-gressing Cavity Pump (PCP) is able to fulfill these requirements and is a good selec-tion for multiphase fluid transfer. In comparison to other pumping systems the PCP is an attractive cost effective solution.
