title = "A case study of porosity prediction from seismic inversion in a carbonate oilfield, Abu Dhabi, UAE",
abstract = "Poststack seismic inversion was performed on data from a carbonate oilfield in Abu Dhabi. The field consists of two separate reservoirs (Arab C and Arab D). The Arab C reservoir comprises a sequence of dolomite sub-zones separated by layers of anhydrite. The underlying Arab D is a complex carbonate lithology with highly variable porosity. In the available 2D seismic data, these units are not resolved, making reservoir characterization through seismic attributes impossible. Following accurate well-to-seismic tie, the major horizons were picked in the 2D seismic data for structural mapping. In addition, detailed analysis of well-log data was performed to identify relationships between seismic response and various reservoir parameters. The seismic data were then inverted to obtain acoustic impedance using constrained sparse-spike inversion algorithm to improve the vertical resolution and the prediction of lateral variations in reservoir quality. The porosity distribution of the reservoirs was estimated using multiattribute transforms. The model greatly improves the understanding of the distribution of porosity in the reservoir zones showing variations in porosity both vertically and laterally.",
