Abstract
One of the key elements in unravelling the structural geometry of carbonate reservoirs is the analysis of seismic data. This poster is compiled primarily to give an insight in the visualization techniques used to highlight fault/fracture patterns. Secondly a work around is given to solve the problems encountered with data management between the different software packages used in the studies. The two case studies discussed are both part of separate multi-disciplinary asset studies carried out in the Shell International Carbonate Development team in Rijswijk. The first study (carried out in the first half 2000) focussed on the Upper Cretaceous Natih E reservoir of the Fahud oil field in Oman. The shallow onshore seismic data suffered from severe noise and quality loss due to amongst others soft overburden. The second study, which is still under evaluation, is carried out on the pre-stacked imaged seismic data in the foothills of the Rocky Mountains in Alberta. The North Waterton gas reservoirs are situated in the thrusted Lower Carboniferous to Devonian sequence. Due to the large terrain effects the seismic acquisition and processing is a tedious job with results that are difficult to interpret.
