... models. The analytical models are used to determine wellbore stresses that are applied to 3D discrete element models of typical well sections. Wellbore models and boundary conditions are based on subsurface conditions encountered in well IDDP-1 of the Iceland Deep Drilling Project. Possibilities of using...

... pressure changes and flow rates with actual measurements using a newly developed fully coupled three-dimensional (3D) network flow and quasi-static discrete element model (DEM). The quasi-static DEM model, which is constructed by Delaunay tessellation of the rock volume, considers rock fabric...

... a better understanding of physics associated with hydraulic fracturing process. In this paper, we present a physics-based hydraulic fracturing simulator based on coupling a quasi-static discrete element model (DEM) for deformation and fracturing with conjugate lattice network flow model for fluid flow...

... of these analysis in engineering applications, where multiple analy- ses are performed for parametric studies. Significant speed-ups are only possible by exploiting the inherent parallelism in the time integration of the discrete element models and the use of the massively par- allel computers. Discrete element...

... ABSTRACT: We present numerical simulations using a flow-coupled discrete element model, developed by authors, to study the lateral growth and interaction of fluid driven fractures in unconsolidated formations. This new approach accounts for the development of anisotropy in micro-structure...
