Sequence Stratigraphy and Reservoir Heterogeneity Related to the Mishrif Formation, Rumaila Field, Southern Iraq

The Upper Cretaceous Mishrif Formation of southern Iraq is part of a large shallow carbonate platform system developed on the Arabian plate. The carbonates are of a high economic importance since they provide the host of large hydrocarbon accumulations of the giant oil fields of southern Iraq. A series of sedimentological, diagenesis, chemo-, and biostratigraphic studies were performed and integrated in a sequence straigraphic framework. Furthermore, first interpretation results from a 3D seismic analysis suggest lateral heterogeneities of these carbonates.
