The project is to develop new methods to allow efficient, flexible and reliable numerical approximations of the mathematical models of the welltest analysis process, and hence to improve the effectiveness and extend the capabilities of welltest analysis as an assessment technique in the oil and gas industry.The numerical approximation techniques that we shall develop are based on the use of overlapping grids. This will allow us to build up the computational domain for complicated reservoirs in a modular fashion, using sub-grids fitted in an optimal way to standard geological features. These include wellbores of all orientations and types, faults, boundaries between regions of different rock types and around the boundary of reservoirs of complicated shapes. The problem will be solved locally on each sub-grid and matched globally via interpolation in the zones of overlap.We plan to start with models in two spatial dimensions (2D) to develop and analyse the techniques, and then move on to the full 3D model. EPS Limited will provide us with data and advice on the requirements of the oil and gas industry.
