Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous computer processing time. In such cases, a simple statistical model may be a good approach to...

Reservoir Computing is a new paradigm to use artificial neural networks. Despite its promising performances, it has still some drawbacks: as the reservoir is created randomly, it needs to be large enough to be able to capture all the features of the data. We propose here a method to start with a large reservoir and then reduce its size by pruning out neurons. We then apply this method on a prot...

Reservoir computers are a type of neuromorphic computer that may be built an analog system, potentially creating powerful small, light and consume little power. Typically reservoir is build by connecting together set nonlinear nodes into network; the difficult or expensive, however. This work shows how expanded adding functions to its output. The particular described here linear filters, but ot...

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...

The quest for efficient and scalable parallel reservoir simulators has been evolving with the advancement of high performance computing architectures. Among the various challenges of efficiency and scalability, load imbalance is a major obstacle that has not been fully addressed and solved. The reasons that cause load imbalance in parallel reservoir simulation are both static and dynamic. Robus...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...
