Faults, fractures, and seals in petroleum reservoirs

Dick Nieuwland 
5 days

Business context

Field development plans hinge on the fluid flow in the subsurface. Flow of oil and gas through porous reservoir rock is controlled by the permeability of the reservoir. In the simplest case this is a single permeability system that is completely controlled by the rock properties of the reservoir. The presence of faults and/or fractures complicates the flow by creating a dual porosity/ permeability system: open fractures are super fluid conduits, while sealing faults or fractures create barriers to flow or even reservoir compartmentalization.

Who should attend

Geologists, geophysicists and reservoir engineers who have to work with faulted and fractured reservoirs will benefit from this short course. The topic is relevant for exploration as well for production.

Course content

In this course the origin of faults and fractures and their mechanical properties will be discussed in a framework of geo-mechanics.

  • Fundamentals of geomechanics
  • Origin & physical properties of faults
  • Origin & physical properties of fractures
  • Fault seal behaviour under varying stress fields
  • Predictive models for fault and fracture fluid conduit behaviour.
  • Compartmentalization in structurally complicated reservoirs.

Learning, methods and tools

A combination of theory, case histories and exercises will be used to familiarize the participants with the various subjects. The course is designed around case histories, rather than around a full in-depth treatment of the geomechanics theories
