Strength of rocks in the confined tension region, where the minimum principal stress is tensile, has only infrequently been measured and is not well understood. Quasi-static confined Brazilian tests under a range of confining stresses (2.76 to 27.58

Permeability measurements were made on sandstone during confined Brazilian strength tests. The test involves 50 mm diameter disk-shaped, jacketed samples that are subjected to confining stresses while they are diametrically loaded. Specially designed

ABSTRACT: Rock salt is being considered as a medium for energy storage and radioactive waste disposal. A Disturbed Rock Zone (DRZ) develops in the immediate vicinity of excavations in rock salt, with an increase in permeability, which alters the migr

The integrity of cemented wellbores is fundamental to the containment of subsurface greenhouse gases and hydrocarbons, while minimizing migration of deep subsurface brines. These brines contain sal...

It has been shown experimentally that under mixed tensile and compressive stress states, a corresponding mixed-mode fracture will occur. In this paper, the formation of mixed-mode fractures is investigated using the combined finite–discrete element

Wellbores are comprised by a steel casing surrounded by a cement sheath. The microannulus is the typically very small annular or degraded space that may develop between cement and casing that has been identified as a common leakage pathway in wellbor

The cemented annulus behind casings and liners is a critical barrier element not only for oil and gas wells, but also for geothermal wells and underground CO2 storage. Corroded casing has been identified as one possible leakage pathway along wellbore
