CO2-EOR PROCESS MODELING & ENGINEERING
Geogreen can provide clients with customized solutions for oilfields that are potentially eligible for EOR via carbon dioxide injection (CO2-EOR). This analysis takes into account oil gravity, miscibility criteria, the original oil in place (OOIP), the cumulative production, and the field’s estimated production life. Depending upon the operator objectives, Geogreen may deploy different modelling tools ranging from quick-look analysis to full field 3-D compositional model. The results from a first “quick-look” allow Geogreen, on the basis of field modelling, to provide the client with the potential incremental oil recovery with EOR, injection scheduling, production forecasts, and how/where/when the CO2 breakthrough to production wells could likely occur. In addition, according to the specific strategy of the operator, the options of CO2 recycling can be estimated as part of this analysis, the purpose being to produce a global view to the client while accounting for operator constraints (economic specifics, facilities status, contractual constraints) and simulation results,
