In-Situ Heavy Oil

Advancing Thermal Extraction Technologies

When heavy oil and bitumen deposits are located too deep for surface mining, operators must bring the heat to the reservoir. Thermal in-situ methods, such as Steam-Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS), are marvels of modern engineering, requiring colossal amounts of high-pressure, high-quality steam. The ACP Group provides top-tier In-Situ Heavy Oil engineering, designing the massive central processing facilities (CPFs) and well pads that make thermal extraction possible.

In-situ projects operate as massive closed-loop water treatment and steam generation ecosystems. The defining variable of success is the Steam-to-Oil Ratio (SOR). Our engineers focus relentlessly on optimizing this metric—designing facilities that maximize thermal efficiency, aggressively recycle produced water, and minimize natural gas consumption required to fire the boilers.

SAGD and CSS Facility Engineering

ACP Group's expertise covers the entire surface footprint of a thermal heavy oil project. Our core engineering solutions include:

• Steam Generation: Advanced engineering of Once-Through Steam Generators (OTSGs) and Drum Boilers, optimizing burner management systems to produce high-quality, high-pressure steam securely and efficiently.
• Produced Water Recycling: Designing severe-duty Warm Lime Softening (WLS) and mechanical evaporation (MVR) systems that treat highly silica-laden hot produced water, achieving recycling rates above 95% for steam generation.
• High-Temperature Well Pads: Designing specialized SAGD well pads capable of handling aggressive thermal expansion, high-temperature multi-phase fluids, and integrating automated choke controls to maintain ideal sub-surface steam chamber pressures.

Digital Twins and Asset Management

Thermal facilities run continuously under extreme pressures and temperatures, making equipment reliability the linchpin of profitability. ACP Group deploys advanced Digital Twin technologies specifically modeled for in-situ facilities. These highly integrated systems pull data continuously from the Distributed Control System (DCS).

By running complex thermodynamic simulations in parallel with live operations, we provide operators with prescriptive insights to optimize OTSG firing rates, predict heat exchanger fouling, and manage boiler feed water chemistry, substantially mitigating the risk of unplanned outages and tube ruptures.

Reducing the Carbon Intensity of Bitumen

We recognize the environmental pressures facing thermal heavy oil production. ACP Group engineers are at the forefront of decarbonizing SAGD operations. We actively design integrations for solvent-assisted recovery (SA-SAGD), co-generation power plants, and modular carbon capture systems to dramatically lower the Life Cycle Carbon Intensity (CI) of produced bitumen, ensuring our clients remain competitive in a transitioning energy market.
