Silty shale
Shale is a fine-grained sedimentary rock that is formed when silt and clay are compressed. It is composed of many thin layers, and it readily splits into thin pieces where these layers meet—making it a relatively brittle stone. [2] Shale is composed of small grains and various minerals along with organic particles.Integrated study of several long continuous cores and wireline logs led to defining nine distinctive lithofacies on the basis of their physical, chemical, and biological characters: …Jun 1, 2016 · Low possibility of capillary breakthrough of CO 2 phase from silty shale caprocks. Abstract For a low-permeable water-saturated cap-rock, interfacial tension between CO 2 and connate water and interfacial interactions among reservoir rock, connate water and CO 2 system are major parameters to evaluate the capillary sealing characteristics of ...
