... 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...

... contains wellbore blocks at the center of the caverns and allows each cavern to be configured individually, was constructed to investigate the wellbore damage mechanism. The causes of the damaged casing segments are a result of vertical and horizontal movements of salt dome top. To assess how much...

... 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...

... 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...

... are self-healed with time. Taking advantage of these properties, caverns developed by solution mining in salt domes may be used for storage of hydrocarbons and other products, for example CO 2 . Special attention is given to the geomechanical structural design of the caverns using computer codes developed...

... Abstract We predict anisotropic velocity perturbations around a salt dome on the edge of the Sigsbee escarpment in the Gulf of Mexico, using a combination of 3D geomechanical modelling and the application of rock-physics predictions. The modelling predicts an increase in compressive stress...

... 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...
