Course Description

Advances in Characterization, Modelling and Simulation of Fractured Reservoirs

Duration: 5 days

 

  • Presenters: Professor David J Sanderson (University of Southampton, UK),  Professor Martin Blunt (Imperial College, London)
  • Prerequisites:  A basic understanding of multiphase fluid flow and fractured reservoirs.
  • Aims:  To give an overview of the state-of-the-art in reservoir characterisation and simulation including discrete fracture simulation and field-scale dual porosity modelling.
  • Who should attend? Reservoir engineers and geoscientists working on fractured reservoirs.

Learning Outcome: The course conveys an understanding of fracture reservoir characterisation and corresponding typical flow behaviour of fractured reservoirs and the shortcomings of conventional models as illustrated by simulation results.
