Eclipse EOR

Simulate the full spectrum of enhanced oil recovery methods and model CO2 capture and storage projects

Overview

Robust, reliable reference simulator

Eclipse EOR enables modeling chemical enhanced oil recovery techniques to improve tertiary recovery within the simulation workflows.

The result is fast and accurate prediction of the dynamic behavior, as described in the following for some of the most common methods.

Applications

Solvent modeling.
Foam progression tracking.
Polymer modeling.
Surfactant modeling.
Alkaline injection simulation.
Alkaline-surfactant-polymer (ASP) simulation.
CO₂injection, storage, extraction, separation and mixing simulation.

Benefits

Polymer

Adding polymer to injected water decreases its mobility and hence reduces viscous fingering and improves sweep efficiency. The mobility reduction is due to two effects: The viscosity of the polymer solution is higher than that of pure water, and the reservoir permeability to water is reduced as a result of polymer adsorption onto the rock while the mobility of oil is unaffected. Eclipse EOR’s polymer model takes into account both of these factors using a modified Todd-Longstaff approach to model fluid viscosities, polymer-water mixing, and resulting slug deterioration.

In consideration that many polymer types show a large dependency on the presence of salt, Eclipse EOR enables investigating the effects of brine concentration on the efficiency of the polymer flood. The simulator also takes into account the inaccessible pore volume arising because of the large size of the polymer molecules.
