Introduction to reservoir simulation as practiced in industry
For more than 50 years, computer simulations have been used to understand and forecast fluid flow in petroleum reservoirs. Somewhat simplified, a simulation model consists of three parts: (i) a volumetric grid with cell/face properties that describes the given porous rock formation; (ii) a flow mode...
Fully implicit higher-order schemes applied to polymer flooding
A Feature-Enriched Multiscale Method for Simulating Complex Geomodels
Multiscale methods have been shown to offer an order-of-magnitude increase in the speed of reservoir simulators. This may enable users to model complex fluid flow and geology with greater speed and flexibility than is available with the current computational technologies. Contemporary multiscale met...
A General Non-Uniform Coarsening and Upscaling Framework for Reduced-Order Modeling
This paper presents a general framework for constructing effective reduced-order models from an existing high-fidelity reservoir model, irrespective of grid topology. We employ a flexible hierarchical grid coarsening strategy that is designed to preserve geologic features and structures in the under...
On obtaining optimal well rates and placement for CO2 storage
Large-scale storage of CO2 in saline aquifers is considered an essential technology to mitigate CO2 emissions. Storage potential has mainly been estimated based on volumetrics or detailed simulations for specific injection scenarios. In practice, achievable storage capacity will depend on engineerin...
Successful application of multiscale methods in a real reservoir simulator environment
For the past 10 years or so, a number of so-called multiscale methods have been developed as an alternative approach to upscaling and to accelerate reservoir simulation. The key idea of all these methods is to construct a set of prolongation operators that map between unknowns associated with cells ...
Fully implicit simulation of polymer flooding with MRST
The present work describes a fully implicit simulator for polymer injection implemented in the free, open-source MATLAB Reservoir Simulation Toolbox (MRST). Polymer injection is one of the widely used enhanced oil recovery (EOR) techniques and complicated physical process is involved, which makes ac...
