The Oukaimeden Sandstones Formation is an Upper Triassic fluvial/aeolian formation located in the High Atlas Range of Morocco. The study area offers extensive outcrops in excess of 200 m high and extending for many kilometres. The formation is composed of stacked lenticular shaped sand bodies often containing cross-bedding and current ripples, interbedded with more tabular shape fluvial bars showing erosional bases with conglomeratic lags containing rounded pebbles of quartz, chert and felsic volcanics. Minor amounts of interbedded siltstones and mudstones are also present showing bioturbation and some lamination. The application of high resolution 3D laser mapping (LIDAR) to these outcrops combined with Differential Global Positioning System (DGPS) mapping and traditional sedimentological data have provided a very powerful and detailed dataset from which several ‘close to deterministic’ reservoir models have been produced. 31 separate LIDAR scan positions containing over a billion points has been collected covering a total area of 5 km long by 250 m high, along with a high resolution field dataset consisting of 12 sedimentary logs 3 gamma ray sections and analyses of the different geo-objects. New approaches and methodologies have been developed in order to integrate the different data into a 3D georeferenced framework.
