Gradient-Based Production Optimization in Reservoir Development

One of the core contents intelligent oilfield is to develop proved oil resources economically and effectively. The way realize it make reservoir development in optimal state real time based on existing production conditions. Water flooding a commonly used technique after primary recovery. However, due influence formation heterogeneity, injected water breaks through high permeability layer traps crude untouched. In order solve such problems, new control model proposed here, which aims maximize net present value production. By solving mathematical production, input output parameters are optimized obtain scheme. This numerical simulation optimization theory. gradient variables, multiple objective strategy schemes (such as one aiming at economic benefits) can be according different needs assist decision. On basis theoretical research, this optimize calculation analysis examples, results show that scheme line with actual oilfield, provides technical support for development.
