Upscaling of the geological model is an important stage in a reservoir simulation work-flow that introduces error due to averaging of sub-grid heterogeneity and numerical diffusion. Upscaling errors are generally more severe in compositional flow simulation than in black oil modeling due to the inherent equilibrium assumption that increases numerical diffusion significantly. When coarse grid …

Abstract History matching of the numerical model was conducted in a heterogeneous sandstone reservoir where the hydrocarbon gas injection inter-well test was implemented to confirm the injectivity and the incremental oil effect prior to the expansion to full field operation. To decrease the degree of the misfit between simulated and measured values, some of the …

Abstract This paper presents a coupled geomechancal and fluid flow simulation for a hydrocarbon reservoir in exploitation process. Two simulators have been used: 1. Geomechanical simulation software FLAC3D which uses Finite Difference Method and 2. tNavigator which is a Finite Element solver engin for fluid flow simulation in porous media. The parameters connecting fluid flow …

Abstract Currently, to build models for dynamic simulations of large oil and gas fields, engineers have to upscale the original geological grid not to exceed limits set but by computer memory size, CPU performance, and by the capabilities of standard commercial software packages. As a result, the upscaled model often has a rather low level …

Abstract Realistic simulations of full-field models including hydraulic fractures made at producing and injecting wells, and fractures created automatically, when the bottom hole pressure at injectors exceeds the overburden pressure remains problematic in the most commercial hydrodynamic simulators. The existing software can either provide a very detailed fracture dynamics description for one or few wells …
