Enhanced Oil Recovery (EOR)
Chemical Solutions for Optimizing Hydrocarbon Recovery in Conventional and Unconventional Reservoirs
The Challenge in Oil Recovery
In primary and secondary recovery methods, only between 20% and 30% of the original oil in place (OOIP) can typically be recovered using conventional techniques.
A significant portion of crude oil remains trapped in the porous medium due to:
-
Capillary trapping phenomena
-
High crude oil viscosity
-
Reservoir heterogeneity
-
Low permeability in certain formations
Optimizing production requires the application of advanced Enhanced Oil Recovery (EOR) technologies.
Enhanced Oil Recovery (EOR)
EOR techniques can increase additional recovery by 10% to 30% or more, depending on reservoir conditions.
Among chemical EOR methods, the most common include:
-
Injection of viscosity-enhancing polymers
-
Surfactant systems
-
Alkaline agents
-
Combined formulations (ASP)
These solutions allow:
-
Improved volumetric sweep efficiency
-
Reduced differential mobility between water and oil
-
Lower residual trapping
-
Optimized displacement of crude oil toward production wells
Polymer Injection
Polymer injection is one of the most established techniques within chemical EOR methods.
By increasing the viscosity of the injected water in a controlled manner, the mobility ratio improves, reducing the formation of preferential flow channels and increasing sweep efficiency.
This allows:
-
Greater incremental hydrocarbon recovery
-
Lower cost per additional recovered barrel
-
Improved operational stability of the injection system
-
Optimization of field performance in the medium and long term
Polymers can be used individually or combined with surfactants and alkaline agents to maximize process efficiency.
Hydraulic Stimulation (Fracturing)
In low-permeability formations, hydraulic stimulation improves reservoir conductivity through the controlled generation of fractures.
The use of fluids formulated with polymers and specific agents allows:
-
Control of fracturing fluid rheology
-
Optimization of proppant suspension and transport
-
Improved fracturing efficiency
-
Reduced operational risks and performance losses
These solutions help increase well productivity in unconventional reservoirs.
