Petrel Fracture Modeling

This course covers the concepts of fracture modeling in relation to how it is used in Petrel and the oil industry in general. It focuses on which input data are available (like image log interpretations) and how they can be used in Petrel. Various processes will be used to view, quality check and manipulate the input fracture data (logs, stereonets, etc.)

 In Petrel, fracture modeling is split into two processes; generation of a Fracture Network model and Upscaling fracture attributes to generate fracture porosity, permeability and Sigma (connection) factor. The Fracture network model consists of a Discrete fracture network (DFN) and Implicit fracture properties (IFM). Various geological, structural and  seismic fracture drivers will be used for Fracture intensity description, and  ultimately combined using artificial neural networks. The fracture modeling course will briefly cover how the output fracture properties can be used for simulation.
