Abstract

The porosity-permeability ratio on carbonate reservoirs is a complex subject. The objective of this study is to contribute for the investigation of the role of fractures on carbonate rocks´ permeability. For that we studied, from a geomechanical perspective, the process of development of the second biggest cave on the carbonate rocks of the Jandaíra Formation (Potiguar Basin, NE Brazil) . This cave (the Furna Feia) presents evidences of structural control and the numerical models performed on this study indicated that the fractures on the cave´s area are in dilation as a function of the present-day stress regime on the Basin. This process probably is a main factor for the conduction of fresh water flow along the natural fracture network on that area.
