Evolution of Paleogeomorphy and sedimentary of the Late Cretaceous on the H oilfield, Iraq

Abstract

The southeast Iraq (SE) occupies a significant role in the oil and gas industry of the world, which was ramp sedimentary environment in the foreland basin of Mesopotamia during the Late Cretaceous. Massive porous bioclastic limestone reservoirs were developed in the Khasib, Sadi and Hartha Formation of the Upper Cretaceous, while the complex porosity and strong heterogeneity in the study area severely restrict the further development.
