Abstract

Summary

We present the results of numerical modelling of the dynamics of active salt diapir formation beginning with the initiation of salt movements due to thick-skinned extension of subsalt medium through later stages of creep and brittle deformations of the salt overburden up to the time of the emergence of salt at the surface of its overburden. The numerical modelling algorithm is based on a combination of full dynamic modelling (FDM) of any natural medium with simultaneous ductile and brittle behaviours and the finite element modelling (FEM) of viscous salt flow. The possible mechanism of the formation of highly tilted blocks nearby the walls of salt diapirs is explained by the FDM. The modelling results on the importance of buoyancy forces and erosion as driving mechanisms of the growth of salt diapirs conform to previous models obtained with the use of FEM. The results are also supported by observations in the Dniepr-Donets Basin. The modelling based on the FDM provides an effective additional tool for hydrocarbon exploration and making decisions on development of storage potential for radioactive waste and carbon dioxide.
