    Exploration, appraisal and development plans hinge on an understanding of fluid flow in the subsurface and the control imposed by geological structures. 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 act as fluid conduits and result in flow anisotropy, while sealing faults or fractures create barriers to flow or even reservoir compartmentalization.

    A combination of theory, case histories and exercises will be used to familiarize the participants with the various subjects. The course incorporates case histories to demonstrate the application of the geomechanical and geometrical theory to the analysis of fields and prospects.



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


    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.
