f Matrix Fracture Interaction in Sandstone Rocks During Carbon Dioxide Injection

The aim of the study carried out is to investigate matrix-fracture interaction during CO2 injection. In the study, an experimental work is being carried out to understand the mechanisms of the gasoil gravity drainage (GOGD) concept by the means of CO2 injection. Experiments are conducted by using sandstone core samples and n-decane is used as the oil phase. One of the purposes of the study is to improve the understanding of the influence of a fracture on the GOGD process. In the fractured case, a space is created around the core sample inside the core holder and the space is considered as a surrounding fracture. During the experimental study, pressure, temperature and recovery measurements are conducted.
