Abstract With growing complexity and grid resolution of the numerical reservoir models, computational performance of the simulators becomes essential for field development planning. To achieve optimal performance reservoir modeling software must be aligned with the modern trendsin high-performance computing and support the new architectural hardware features that have become available over the last decade. A …

Abstract The article addresses the problem of numerical simulation of the salty water properties after the dissolution of hard reservoir salt following water flooding. A new method is being proposed for the simulation of reservoir salt dissolution within the isothermal models of black oil and compositional model of hydrocarbon filtration, based on fully implicit numerical …

Abstract A method to locate critical wellbore intervals during oilfield development is proposed in this article. A variant of fully coupled geomechanics approach is used. Geomechanical 3D modeling is performed on the same mesh that is used for reservoir simulation. The proposed algorithm uses Mohr-Coulomb criterion to locate critical wellbore intervals.

Abstract For modern day reservoir simulators, it is essential to provide realistic physical description of reservoirs, fluids and hydrocarbon extraction technology and guarantee excellent performance and parallel scalability. In the past, the advances in simulation performance were largely limited by memory throughput of CPU based computer systems. Recently, new generation of graphical processing units (GPU) …

Summary Multiobjective history matching has gained popularity in the last decade. It provides an ensemble of diverse set and good matched models that should lead to improved forecasting. Moreover, in some cases, multiobjective history matching provides faster and more-robust convergence than the single-objective approach. In multiobjective, objective components (usually groups of them) guide the algorithm …
