Naturally Fractured Reservoir Engineering

Training Provided by HOT Engineering The presence of extensive networks of natural fractures creates a number of challenges for evaluating and optimizing recovery from naturally fractured reservoirs. The use of dual porosity or dual permeability approaches is often necessary, providing the basis for both analytical models (such as used for pressure transient analysis) as well as for reservoir simulation. Appropriate application of dual porosity and dual permeability models, however, rely on: a) accurate representation of the fracture system as an equivalent porous and permeable medium, and b) accurate determination of the rates of fluid transport between matrix blocks and the fracture system. This course covers modern reservoir engineering methods applicable to naturally fractured reservoirs, focusing on the application of dual porosity and dual permeability models. Although information will be presented on analytical models and methodologies, a primary focus of the course will be on the use of dual porosity/ dual permeability numerical reservoir simulation.
