Rock mechanical properties
WebThe Opalinus Clay (OPA) is a clay-rich formation considered as a potential host rock for radioactive waste repositories and as a caprock for carbon storage in Switzerland. Its very low permeability (10 −19 to 10 −21 m 2) makes it a potential sealing horizon, however the presence of faults that may be activated during the lifetime of a repository project can … Web1 Jan 2016 · According to Kahraman et al., the significant rock properties that influence the penetration rate of drill bits during drilling operations are specific energy (SE), unconfined …
