Artificial lift PCM

Cold heavy oil pumps

Heavy oil production has large range of complex requirements. The ability to pump sand and viscous fluids has made PCM Moineau™ pump systems the best adapted choice for handling heavy oil production.

Heavy oil challenges

The geological characteristics of the reservoir and the low mobility of heavy oil make recovery difficult, which means it is an ideal candidate for Thermal Enhanced Oil Recovery (EOR) techniques.

  • Low well productivity requires drilling wells with horizontal drains, with highly deviated profiles when the reservoir is shallow.
  • Sand production (Cold Heavy Oil Production with Sand – CHOPS) is a challenge because of abrasion (downhole and on surface), plugging and oil handling at the surface.

Viscous oil produced with water can cause emulsions, which lead to high loads on artificial lift systems, high energy consumption and costly chemical.

Technical challenges

Heavy oil must be thought of differently from conventional oil because of its physical characteristics– API degree below 20 – and because of its huge economic potential and specific technical challenges.

Economical challenges

The world’s heavy oil reserves are estimated to be twice that of conventional oil reserves. As an example, the Orinoco Belt heavy oil reserves in Venezuela contain approximately the same amount as the conventional reserves of Saudi Arabia (250 Gbbl).

Heavy oil is found mainly in Canada and Venezuela. Many other countries have smaller, but nevertheless substantial, heavy oil resources. Finding a way to cost effectively extract and refine heavy oil will contribute to meeting the world’s oil demands in the decades to come.

Why choose PCM for the cold heavy oil pumping ?

PCM solutions

A multiphase fluid is a mixture of oil, water, gas and often some solid particles. Fluid characteristics (densities, viscosities and mixture composition), flow (pressure and temperature) and piping and well architecture determine the flow pattern, which in turn defines the multiphase flow behavior.

In oil & gas activities, multiphase conditions are omnipresent -- from the reservoir through the well and up to processing -- and must be taken into account when designing artificial lift systems.

PCM has perfected a patented self-pressure regulation technology called HRPCP (Hydraulically Regulated PCP) that allows PCPs to be used for multiphase pumping. It is available on PCM Moineau™ HR systems for artificial lift.
