Summary:
The recent surge in CO2 rich gas injection activities for both Capture Carbon and Sequestration (CCS) and Enhanced Oil Recovery (EOR) projects have led the oil industry and the academia to explore the implications of rock-fluid interactions at full scale development projects. Some of the main questions are: Do reactions occur? Are they relevant for CO2 capture and/or oil recovery? How to monitor them? To illustrate some of the ways the industry may tackle these questions reactive transport simulations have been made to evaluate the impact of rock-fluid interactions in the seismic, mechanical and flow properties in an outcrop based 3D geocellular model. Changes in elastic properties are evaluated using a flow coupled petroelastic model based on an effective medium approach. Current challenges to develop pore-to-reservoir reactive models will also be addressed.
