Use of pore scale simulators to understand the effects of wettability on miscible CO2 flooding and injectivity
One area of concern accompanying CO2 injection into carbonates is the evolution of permeability and porosity as carbonate dissolves and is redistributed on rock surfaces. The student will employ a network model to gauge how evolving pore topology affects permeability and porosity. The model will be attached to real rock through measured pore-throat and pore-body size distributions before and after CO2 flooding by means of laboratory experiments and thin section analysis. Macroscopic trends will be correlated in terms of network connectivity and pore body to throat aspect ratio.
