Interim evaluation of the predictive capability of salt constitutive laws
The Exponential-Time, Krieg, and Munson-Dawson viscoplastic constitutive models are used in finite element simulations of laboratory, bench-scale, and field tests on Avery Island salt. The simulated laboratory tests were constant stress-rate tests. In these tests, the stress state is homogeneous in space, but varies through time. The simulated bench-scale tests were hydraulic fracturing tests, the state of stress in the salt specimen varies both in time and space. The simulated field tests were corejack tests performed in the Avery Island dome in Southern Louisiana. A corejack test consists of a 1-m-diameter, thick-walled hollow cylinder loaded with a constant pressure on the outside radius of the cylinder. In these tests, the stress state varies with space and is nearly constant through time. All of the simulations resulted in reasonable agreement with the measurements in the actual tests. 16 refs., 42 figs., 29 tabs.
