PCM Troika is a progressing cavity pump that makes it possible to transfer multiphase liquids straight from the well to a central separation station, eliminating the need for on-site separation.
PCM has released a progressing cavity pump designed to handle the surface transfer of high-pressure, multiphase fluids in oil and gas fields.
Many oil and gas wells produce fluids with varying levels of oil, gas, water and other substances, such as sand.
These are referred to as multiphase fluids.
Traditionally, the different component elements are separated on site and the oil is transferred to the processing station.
But as a field grows in size, on-site separation becomes less cost-effective.
Large quantities of separation equipment scattered across a field can be costly and time consuming to maintain.
PCM Troika is a progressing cavity pump that makes it possible to transfer multiphase liquids straight from the well to a central separation station, eliminating the need for on-site separation.
PCM Troika's design overcomes the primary obstacle to multiphase pumping, constantly changing gas-to-oil ratios and pressure levels.
This benefit is enhanced when viscosity is also changing along the lifetime of the well.
This is also the main reason for which other pump technologies (such as centrifugal, plunger and twin-screw pumps) cannot reliably and cost-effectively handle multiphase liquids.
PCM Troika handles virtually any mix of oil, gas, water and sand, including degassing fluids and sour environments.
PCM Troika delivers this performance while providing the inherent advantages of PCP pumping: steady performance, nonpulsating flow and nonemulsifying fluid handling.
PCM Troika also reduces operating expenses and maintenance costs.
Due to its high hydraulic efficiency, it requires lower installed power and uses less electricity.
The robust design ensures long-term performance and increases mean time between failure (MTBF) even when handling complex fluids.
PCM Troika is suited to a wide range of high-pressure, surface transfer applications in the oil and gas industry, including offshore campaign re-injection, water injection and polymer flooding, recovery of condensates and as a commingling booster pump.
Finally, PCM Troika features a modular design that is easily customisable.
This simplifies the selection process and enables customers to obtain a configuration that is specifically tailored to their operational and fluid handling requirements.
