An accurate reservoir characterization is a crucial task for the development of quantitative geological models and reservoir simulation. In the present research work, a novel view is presented on the reservoir characterization using the advantages of thin section image analysis and intelligent classification algorithms. The proposed methodology comprises three main steps. First, four classes of...

Nowadays reservoir simulators are indispensable tools to reservoir engineers. They are widely used in the optimization and prediction of oil and gas production. However, for large-scale reservoir simulation, computational time is usually too long. A case with over one million grid blocks may run weeks or even months. High performance processors and well-designed software are demanded. Though to...

Workflow has been useful in business area for a long time since it helps business process be well defined and be automated. Recently, its use becomes broader and its original model becomes changed. Recent technology such as smart phone and positioning system brings about more dynamic situation to where the workflow can be adopted. The workflow is not routed by the predefined path and condition....

Knowing how scientific results are obtained, meaning to know which methods, techniques, algorithms, software etc. were used, is important for those scientific results to be credible. Documentation and provenance data provide exactly this information. However, providing documentation and provenance data is not trivial. In the domain of Modeling & Simulation a multitude of different building bloc...

Implementation of formal techniques to aid the design and implementation of workflow management systems (WfMS) is still required. We believe that formal methods can be applied in the field of properties demonstration of a workflow specification. This paper develops a formalization of the workflow paradigm based on communication (speech-act theory) by using a temporal logic, namely, the Temporal...

ABSTRACT: A general application model applied to gas reservoir simulation merging elements of the evolutionary and object-oriented paradigms is shown. The model works in three ways: 1. Make an adaptive grid partition of the 3D structure based on a non-linear function. 2. Solve the non-linear algebraic equation systems in each block, which are generated for the gas properties calculation, taking...

Steam injection has had a profound impact on the production of heavy crude oil. Steam, however, is inviscid compared to a viscous oil and is not the ideal displacement agent. Field studies and laboratory tests have shown that foaming the steam phase through the aid of a suitable surfactant in aqueous solution can achieve mobility control of injected gases and mitigate the effects of gravity ove...

We present a reservoir simulation scheme that gives accurate resolution of both large-scale and fine-scale flow patterns. The method uses a mixed multiscale finite-element method (MMsFEM) to solve the pressure equation on a coarse grid and a streamline-based technique to solve the fluid transport on a fine-scale subgrid. Through this combination, we aim towards a numerical scheme that facilitat...

SUMMARY The forthcoming generation of many-core architectures compels a paradigm shift in algorithmic design to effectively unlock its full potential for maximum performance. In this paper, we discuss a novel approach for solving large sparse linear systems arising in realistic black oil and compositional flow simulations. A flexible variant of GMRES (FGMRES) is implemented using the CUDA progr...
