... Sedimentary soft rocks such as mudstones are possibly deteriorated due to dry/immersion cycles, known as slaking, which cause slope instability. However, the slaking-induced deformation characteristics of crushed mudstones under cyclic and slope stress conditions have not been understood well...

... Abstract This study presents the use of a leak-off test (LOT) to estimate mudstone permeability, in which mudstone plays a role as cap-rock formation in a CO 2 sequestration test site, offshore southeastern Korea. LOT is a borehole injection test conducted at an open-hole section below casing...
