Abstract

The injection of CO2 with a suitable aqueous solution of a CO2-foaming agent into a reservoir formation<br>has been shown to improve on CO2 mobility and increase macroscopic sweep efficiency. However, during<br>CO2-foam flooding in fractured chalk reservoirs with low matrix permeability compared to fracture<br>permeability, the solutions will mainly be transported through the fracture network. At higher matrix<br>permeability, viscous flooding of the matrix will also be important. Foam in fractures can divert more of<br>the CO2 and surfactant solution to the matrix.
