Progressive Cavity Pumps for Multiphase Oil, Water & Gas
Positive-displacement transfer for oilfield streams containing changing proportions of oil, produced water, free gas and suspended solids.
One production stream, three phases
Oilfield production streams may arrive as a changing mixture of crude oil, produced water and gas, often with sand or other solids. Progressive cavity technology can be applied to selected multiphase transfer duties because positive displacement, low-speed operation and solids-handling capability can accommodate conditions that are difficult for conventional liquid-only pumping equipment.
Gas fraction and slugging change the duty
A multiphase pump must be evaluated for the complete expected production envelope, not only the average liquid rate. Gas volume fraction, intermittent gas slugs, inlet pressure, differential pressure, fluid temperature, liquid viscosity and solids loading can all affect pump behavior and component life.
