Summary

The analysis of the geological fault formation mechanism is important in petroleum exploration industries. Depending on the existing stresses and flow direction, the faults can become preferential flow channels. Numerical and analogue modeling methods represent two different techniques, which can be used to investigate the evolution of geological structures. The experiment called sandbox has been used to analyze the fault formation mechanism in sedimentary basins. In this paper the analysis of the geologic faults formation mechanisms using the discrete element method, through the numerical sandbox experiment, is reported. This numerical model is composed of distinct particles that displace independently of one another, and interact only at contacts or interfaces between the particles. The discrete element program PetroDEM has been used to study the effect from the movement between blocks with a two-dimensional model. The analysis is performed in a qualitative mode. The simulations are carried out for cases with uniform and non-uniform grain size, which in both cases are analyze the effect of the variation of the tangential stiffness, the effect of parameters in a parametric study of the material properties is investigated. The simulations produce a wide range of fundamental structures similar to those observed in nature and in the analogue models.
