Frictional properties of natural and induced fractures in two types of shales
Abstract This paper presents results of direct shear tests on two types of shales; Rurikfjellet from Svalbard, Arctic Norway and Draupne from Ling Depression, the North Sea. Rurikfjellet formation is part of a caprock system for the proposed CO 2 storage site at Svalbard. Draupne shale forms the cap...
