Qualification of a CO2 Storage Site Using an Integrated Reservoir Study

The scope of this work is to analyze the impact of CO2 injection in Pliocene offshore water-bearing sands potentially suitable for CO2 storage, through the implementation of an integrated reservoir study. The approach undertaken was first to build several geological models (local and regional), stochastically populate them with petrophysical properties and, through the gathering and generation of representative dynamic data, develop a dynamic model to simulate a set of possible CO2 injection scenarios. Furthermore a base case scenario was identified to perform a comparison between two different simulators: COORESTM, a code designed by IFPEN, and ECLIPSE300 - CO2STORETM, the Schlumberger compositional tool designed specifically for CO2 storage in saline aquifers.
