Abstract Oil companies invest significant human and money resources on decisions about field development planning. Often these decisions have to be made based on limited information under tight time constraints. Historically, numerical simulation is one of the main tools in the process. In most cases, the investigations remain limited to single realizations or at best …

Abstract The paper presents efficient implementation of the non-equilibrium phase transitions model in compositional simulator. Reservoir non-equilibrium phase behavior effects are examined and simulated with the new approach. Compositional simulators are widely used for modeling light oil reservoirs, gas injection projects, and gas-condensate reservoirs. Some features for modeling phase transition hysteresis are implemented in black …

Abstract Transient well test data conveys significant information about the subsurface heterogeneities in terms of some variations in the well test pressure response curves. It is therefore important to enhance the use of the well test data for building a validated geological model to include the effective reservoir heterogeneities that are reflected on the well …

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 …

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 …
