Once an EOR method has been selected in a screening process, it is important to evaluate the feasibility of the process for a given field and to optimize the solution at lab scale. Parameters such as temperature, salinity distribution, water quality, geological heterogeneities are key uncertainties that need to be carefully investigate from the beginning of any chemical EOR project in order to ensure the robustness of the chemical EOR process ultimately at pilot and full-field scales.
Our methodology consists in a step-by-step approach where, starting from thousands of possible formulations, it progressively delivers the best solution in terms of EOR process efficiency and robustness.
Step 1: Analysis of reservoir materials (rocks/fluids)
Step 2: Extensive formulation screening
Step 3: Coreflood experiments at reservoir conditions
