Estimation of Propped Volume Permeability Using Strain from Geomechanical Modeling of Interacting Hydraulic and Natural Fractures – Application to the Eagle Ford

Abstract A new workflow that uses the strain derived from geomechanical modeling of hydraulic fractures interacting with natural fractures is applied to an Eagle Ford well. The derived strain map is used to estimate the asymmetric half lengths that are input in any frac design software able to incorporate this new information. The simplistic symmetric …

Three-Dimensional Coarse-Scale Simulation of Enhanced Oil Recovery Processes in Highly Heterogeneous Reservoirs

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 …

Application of PSO and MOPSO to Gas Injection Analysis

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 …

Coupled Geomechanical and Fluid Flow Simulation of the Oil Field Evolution Induced by Reservoir Production

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 …

Application of Sector Modeling Technology for Giant Reservoir Simulations

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 …
