Enhanced Oil Recovery

Revitalizing Mature Assets

As primary and secondary (waterflood) recovery methods reach their economic limits, traditional oil fields leave billions of barrels of hydrocarbons stranded below the surface. Capitalizing on these mature assets requires highly sophisticated tertiary production techniques. The ACP Group is a premier provider of Enhanced Oil Recovery (EOR) engineering, designing the complex surface infrastructure required to alter reservoir dynamics and sweep trapped oil to producing wells.

EOR projects are inherently capital-intensive and technologically demanding. Depending on the specific geological formation, we engineer tailored facilities for gas injection (CO2, hydrocarbon gases), chemical injection (polymers, surfactants), or thermal recovery. Our overarching goal is to ensure that the surface facilities operate reliably, handle severe corrosion potentials, and minimize operating costs to ensure the long-term profitability of the EOR program.

EOR Facility Engineering Expertise

ACP Group's multi-disciplinary approach addresses the unique mechanical, process, and metallurgical challenges of EOR. Our specific capabilities include:

• Carbon Capture and CO2 Flooding: Designing high-pressure CO2 compression systems, dense-phase pipeline transport networks, and specialized wellhead manifolds, utilizing exotic metallurgies to combat carbonic acid corrosion.
• Chemical EOR (cEOR) Systems: Engineering precise, skid-mounted polymer hydration and blending facilities that preserve the delicate molecular structure of the injectant under highshear pumping conditions.
• Produced Fluid Handling: Designing robust separation facilities capable of breaking complex oil, water, and polymer/surfactant emulsions, ensuring produced fluids meet pipeline specifications while recovering injectants for recycling.

Intelligent Injection Automation

The success of an EOR flood relies on absolute precision at the wellhead. Our system integration division delivers state-of-the-art automation architecture for EOR fields. We deploy advanced flow-control algorithms and Coriolis metering systems that continuously communicate with the central Distributed Control System (DCS).

By providing real-time visibility into injection pressures, flow rates, and chemical dosages across hundreds of injection wells, we help operators prevent reservoir channeling and fracturing, thereby maximizing the volumetric sweep efficiency of the EOR flood.

Synergy with Carbon Capture (CCUS)

CO2-EOR is uniquely positioned at the intersection of energy production and environmental sustainability. ACP Group actively designs EOR facilities that serve as the final anchor point for Carbon Capture, Utilization, and Storage (CCUS) networks. We engineer systems that ultimately securely sequester millions of tons of anthropogenic CO2 deep underground, allowing operators to produce "net-carbon-negative" oil while benefiting from regulatory tax credits.
