Fractured reservoirs contain a significant proportion of theglobal hydrocarbon reserves; however, they commonly exhibitunpredictable and extreme production behaviour. To develop suchreservoirs it is necessary to obtain the best understandingpossible of the fracture network and its impact on the fluidflow within the reservoir, using the full range of geoscienceand engineering datasets available at all scales. This bookpresents an overview of current techniques and the latest technologiesused to understand and exploit fractured reservoirs. The contributionsare organized into sections on outcrop analogues, the applicationof geophysical techniques for fracture detection and imaging,numerical and analogue modelling and case studies from fieldsin the Middle East, Europe and North America. A number of thecase studies also consider ways of assessing uncertainties infracture geometry description and the implications for effectivereservoir management.
