How to Evaluate the How to Evaluate the Potential for EOR in a Tight Reservoir

The presentation focuses on the following key points:

  • Discussion of important well and hydraulic fracture parameters
  • Workflow demonstration using a comprehensive case study evaluating three different flood processes
  • Considerations involving reservoir permeability influence and impact



The webinar demonstrates the integrated-simulation workflow using a model representative of a Western Canadian tight reservoir, containing volatile oil. In addition to primary recovery, we also consider waterflooding, immiscible N2 and miscible CO2 gas flooding. Combinations of these EOR techniques, coupled with the effects of various well and fracture design parameters, are technically explored and economically ranked using a comprehensive economic analysis. In addition, we highlight CMG’s software capabilities for modelling different EOR techniques using IMEX (black oil) and GEM (compositional) reservoir simulators.

To determine the minimum permeability at which these EOR methods are applicable, we apply a sensitivity analysis on matrix permeability, to the optimal case from each process. The webinar also demonstrates CMOST AI’s workflow which ensures the same well and fracture design configurations are run for each recovery process.

Through discussion and demonstration, you will learn how to apply CMG’s software to evaluate the potential application of different EOR processes on a tight reservoir.
