Our cEOR and IOR solutions are designed to help operators extract more production and profit from new and mature hydrocarbon resources. Our custom-tailored polymer injection programs enhance field economics while minimizing environmental impact and operational risk.
Polymer Flooding
Polymer flooding is an enhanced oil recovery (EOR) technique that involves injecting water-soluble polymers into the reservoir to increase the viscosity of the injected water. This process improves the water sweep efficiency by reducing the water-to-oil mobility ratio, allowing for more effective displacement of oil towards production wells. By enhancing the fluid’s movement through the reservoir, polymer flooding helps recover additional oil that would otherwise remain trapped, boosting overall extraction rates.
Surfactant Flooding
Surfactant flooding is an enhanced oil recovery (EOR) technique that involves injecting specially formulated surfactants into the reservoir to lower the interfacial tension between oil and water. This reduction in interfacial tension allows trapped oil to be released from the rock surface and flow more freely towards production wells. Surfactant flooding enhances oil mobility and improves sweep efficiency, making it an effective method for recovering residual oil that conventional water flooding methods cannot extract.

Tailored Polymers For A Wide Range of Field Conditions
To ensure optimal injectivity and sweep efficiency, we focus on four key field conditions
- reservoir temperature
- divalent ion concentration
- salinity of injection and formation fluids
- reservoir permeability.
Salinity and divalent ion concentration of injection and formation fluids along with reservoir temperatures affect the viscosity and stability of the solution. Harsher conditions typically require sulphonated polymers. Molecular weight selection is driven by reservoir permeability range.
