Formation Evaluation of the Cretaceous Kometan Formation in selected wells of oil fields in Zagros Basin, Kurdistan, North East Iraq

The Kometan Formation is a fractured carbonate petroleum reservoir of Upper Cretaceous age. It is part of the most productive oil fields in Kurdistan region and of North Iraq, which is concentrated in the western part of the Zagros Basin (Zagros province). The Kirkuk oil field, Jambur oil field, Khabaz oil field, Bi Hassan oilfield, Taq Taq oil field, Hamren oil field and many others are producing oil in this region.

This Project is focused on evaluating the reservoir characteristics of the Kometan Formation in oil fields of the Kurdistan region of North Iraq Zagros folded zone. The project is using the limited drilled well data available, including wireline logs, cuttings, core and oil samples from selected fields, in conjunction with geological fieldwork, petrophysical and laboratories methods to better understand the sedimentological, structural and sequence stratigraphical relationships in these carbonate rocks which have never been properly investigated.

The aims of this project are to investigate the effect of heterogeneity resulting from lithological and sedimentological variations on the reservoir characteristics of the Kometan Formation in different fields across the Zagros Basin. This is being achieved through evaluation of the structural rock mass anisotropy in relation to fracture development and tectonic evolution of the region. By combining this with investigations of the sequence stratigraphy and the interaction of the dual-permeability reservoir characteristics throughout the Zagros Basin we can establish the reservoir potential, assess of reservoir fluid saturations and detect hydrocarbon flow to better evaluate future reservoir production.
