Shale is the most common stone found in the sedimentary rock family. It makes up about 70% of the earth’s outer crust. Shale Rocks are commonly referred to as Claystone because they are composed of mud and clay sediments that have accumulated over a long period of time. At the same time, shale as a source rock contains a considerable amount of OM that is poorly understood under the influence of SC-CO 2 treatment. When the high-mature LMX shale is exposed to SC-CO 2, limited influence is observed in OM, showing that the micropore size tends to decrease and macropore remains almost unchanged, as shown in Fig. 5 (a).Estimating compressive strength.
