Pars Reservoir Simulator (PRS) ^Popular

Pars Reservoir Simulator (PRS) it is comparable and competitive to all commercial products with respect to the wideness of applicability, size of the models CPU time and user friendliness. It is an all purpose simulator equally handling black oil and compositional single and dual porosity and permeability models usable on unstructured and time depending grids. Main Functionalities PRS Supports:  Black Oil & Compositional Formulation  Single Porosity, Dual Porosity , and Dual Permeability Formulation  Numerical and Analytical Aquifer Models  Common PVT and SCAL Models  IMPES, AIM, FIME Formulation  GMRES, Direct, ORTHOMIN Linear Solvers  Interface for Converting Available Eclipse Model to PRS.  Automatic history matching Black Oil & Compositional Simulation o Full Three Dimensional Simulator. o Same Engine for Black Oil and Compositional Models. o Considering Black Oil Model as Special Case of Compositional Model o Components are Oil, Gas, Water, Solution Gas, etc. o Compositional Simulation of Hydrocarbon Mixtures up to 12 Components. o Robust, Well Posed Phase Equilibrium Calculation Engine. Single and Dual Media Simulation o Single Porosity Option for Conventional Reservoir Study. o Double Porosity/Permeability Models for Naturally Fractured Reservoirs. o Fractured Reservoir Mechanism Options: o Viscous Displacement o Gravity Imbibition\Drainage o Two Different Dual Permeability Concepts: o 3D Dual Permeability o 1D Column Dual Permeability Aquifer Models o Gridded Aquifer o Outer Boundary Concept 0 Steady State (Schilthuis Formula) 0 Non-steady State 0 Transient (Carter-Tracy Model) 0 Pseudo-steady State (Fetkovich Model) 0 Semi-steady State SCAL Options o Saturation Functions 0 Imbibition Functions 0 Drainage Functions o Rock compressibility factor o Hysteresis o Endpoint Scaling 0 Second Rock Region PVT Options o For Black Oil Model: 0 PVT Tables o For Compositional Model: 0 Equation of State 0 SRK 0 PR 0 Modified PR 0 Phase Properties Calculation 0 Viscosity 0 Surface Tension 0 … 0 Separators Solver o Different Model Formulations: 0 IMPES 0 FIM 0 AIM o Direct Linear Solver (Gauss Elimination) for Small Scale Simulations o ORTHOMIN and GMRES with Pre-conditioner ILU for Large Scale Simulations Eclipse to PRS Conversion o An option for Converting Eclipse Setup to PRS Setup o Save the Time respect to Construct a New Model o Preparing the Input Files for PRS o Doing Adoptions in Some Input Files of Eclipse Automatic history matching o Automatic history matching based on the Target Pressure and Phase Method (TPPM) is an option in PRS. The ultimate goal is to enable real time Simulation and reservoir management. PRS Desk o Schedule Convertor o PRSLauncher
