... studies have been performed to investigate cavern damage as a function of salt roof thickness, overburden stiffness, interface properties, and cavern geometries. Each cavern simulation includes 1 year of pressure cycling with a minimum, mean, and maximum cavern pressure of 6.1 MPa (884.5 psi), 8.8 MPa...

.... Included are confining stress contrast, elastic stiffness contrast, fracture toughness, and influence of settled (or buoyant) proppant on height growth. A composite propagation function was formulated that can be implemented in a pseudo3D model of fracture geometry or in hand calculations. The second part...
