Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1366
... ABSTRACT: We predict pore pressure and stresses from seismic velocity over a volume around a salt dome in Green Canyon 955, Gulf of Mexico. The salt dome significantly changes the magnitude and orientation of principal stresses in surrounding rocks. To account for these changes, we use...

... ABSTRACT: Bayou Choctaw Cavern 20 is located near the edge of the salt dome. Its proximity close to the edge of the dome raises concerns about potential tensile failure in the surrounding rock near BC-20 induced by the cavern volume closure due to salt creep. The location of BC-20 in the salt...

Paper Number: ARMA-2016-410
... Abstract: Rock salt provides the world's best barrier, and has thus long been considered as a host rock for nuclear waste repositories. Salt domes have vertical extensions of several kilometres and are consequently well-suited for deep borehole disposal, as an alternative to a mined...

Paper Number: ARMA-2015-207
... Abstract In recent years, the number of new and planned gas storage caverns has increased, so that optimization of the existing salt deposits and especially the question of the minimum allowable distance between the cavern and the salt dome boundaries became important. Although caverns were...

Paper Number: ARMA-2015-159
... Abstract We use a simple analytical model to estimate the stress field in and near density-driven, rising salt domes. We show that the salt pressure within such domes varies linearly along the dome but with a magnitude greater than the overburden stress. We also show that the salt dome...

Paper Number: ARMA-2014-7027
... Abstract We compare an evolutionary to a static approach for modeling stress and deformation around a salt dome and we show that the two approaches predict different stress histories and very different strains within the adjacent wall rocks. Significantly higher shear stresses develop during...

These analyses represent a first attempt to combine several complex, non-homogen-eous processes in a dome-scale, three-dimensional geomechanical analysis using caverns meshed to measured geometries.

It is believed that the caprock above the solutioned cavity collapsed, resulting in the formation of the surface sinkhole. On September 17, 1980, a drop...
