Boost Production with PCM’s EOR Solutions

In today’s mature oil fields, maximizing ultimate hydrocarbon recovery increases economic viability and extends the productive life of wells. Enhanced Oil Recovery (EOR) is a technique designed to mobilize residual oil in a competitive manner.

Polymer flooding is an EOR technology, which increases sweep efficiency and reduces water production, so that more oil is produced and less water is lifted. Meanwhile, the operators need to maintain the integrity of the polymer solution throughout the transfer of the polymer. PCM transfer pumps offer the lowest shear rates and pulsation levels in the market, they preserve the molecular structure of polymers while enabling high-pressure injection. 

Whether it’s polymer, surfactant, or any other additive, PCM pumps ensure smooth, reliable, and efficient fluid handling across the entire EOR process chain. PCM pumps handle high-viscosity fluids, manage shear-sensitive solutions, or transfer surfactants. Thus, operators can achieve more efficient Enhanced Oil Recovery (EOR) with reduced operational risk.

Challenges in Enhanced Oil Recovery

 

Low Shear Pumping Technologies

During pumping, oil and water mixtures often emulsify, which can hinder separation. PCM surface transfer pumps, using their distinctive progressing cavity pump (PCP) technology, provide gentle, low-shear fluid transfer.

This design helps maintain oil droplet integrity, ensuring optimal separator efficiency. Consequently, it lowers reliance on costly chemical treatments and boosts the overall performance — an advantage over centrifugal pumps, which typically generate higher shear and promote emulsification.

Recycled water 

In improved oil recovery and pressure maintenance operations, treated produced water is reinjected into the reservoir. This requires pumping systems that can:

  • Operate at high pressures (up to 200 bar or 2900 psi)
  • Deliver consistent flow with minimal pulsation
  • Minimize chemical usage through shear-sensitive handling

PCM pumps are ideal for onshore and offshore water injection systems, offering energy-efficient and compact solutions for reinjection of filtered or treated produced water.

FAQ - Enhanced Oil Recovery

 

Why are progressing cavity pumps the best solution for EOR processes?

Progressing cavity pumps (PCPs) are ideal for EOR applications because they provide low shear, low pulsation flow—essential for handling viscous and shear-sensitive fluids like polymer or surfactant solutions. Their ability to maintain polymer integrity leads to better sweeping efficiency and higher oil recovery rates.

 

How do I select the right PCP for my EOR application?

Selection depends on fluid viscosity, chemical composition, required flow rate, and pressure. PCM offers both standard and API 676-compliant pumps, along with custom-engineered solutions. Our technical team will assist you in choosing the best configuration based on your project’s specific needs.

Why choose PCP over other technologies?

Progressing cavity pumps are suited for Enhanced Oil Recovery (EOR) because they offer low shear and pulsation, consistent flow, high-pressure capability in a single stage, excellent solids and gas handling and customizable materials and configurations. Overall, progressing cavity pumps offer the lowest total cost of ownership - making them the top choice for surface operations in polymer flooding and other EOR methods.

Are PCPs suitable for remote or unmanned EOR sites?

Absolutely. PCPs are known for their reliability, long service life, and minimal maintenance requirements. When combined with automated control systems, they are ideal for remote or unmanned installations, ensuring continuous operation with minimal intervention.
