Abstract: Oil Reservoir Simulation is a standard technique for simulating multi-phase fluid flow inside a well. It is essentially needed in the development of new fields to help identifying the number of wells required, the optimal completion of wells as well as the expected production of oil, water and gas. It is also used in the developed fields where production forecasts are needed. We implement a 3D Water-Oil forward reservoir model by discretizing the associated PDE’s using finite volume method (FVM) on a structured grid. The solution of the governing partial differential equations is approximated by the solution of an algebraic system that is found to be sparse and very time consuming for practical well dimensions. We then analyze the program data layout, especially the algebraic solver to develop a parallel model. Our experience in the implementation of the sequential simulator of a (16*16*1 feet) field showed that we require solving a system of non-linear equations of (512 *512) dimensions, that is sparse and hepta-diagonal. As a result, the implementation of that parallel model will largely impact scalability in both time and space by dramatically reducing the normal execution time and enhancing simulation accuracy.
About the speaker: Ayham Zaza has graduated from the Computer Engineering department at KFUPM. He holds an M.S in Medical Physics and currently doing his PhD in Computer Engineering. He has developed several software systems to automate some radiotherapy QA routines at hospitals. Besides his interest in Intelligent Computing and Medical Image Processing (Image Registration), he is currently developing a data parallel simulator for multi-phase fluid flow in oil reservoir on GPU’s using CUDA. He has also attempted developing an intelligent software for an automated early cervical cancer detection.
