Characterization of Structural Geology of Faihaa Oilfield, Southern Iraq

Faihaa Oilfield is a new exploration Iraqi located in southern Iraq and within Mesopotamian Plain, including the Block 9 area, along Iraqi-Iranian border. The study area included (in Iraq) Yadavaran Iran). They belong to one anticline (Dome) structure separated by border, without geological boundary between fields. current aims achieve structural geology analysis (Faihaa/Yadavaran structure). geometric genetic analyses of area. According results, Faihaa/Yadavaran classified as an anticline, gentle, upright, non-plunge, asymmetrical. thickness variation, there are two types formations’ folds recognized, Thickened Supratenuous fold generated folding mechanisms bending buckle mechanisms. Bending form fold, perhaps due vertical uplift salt and/or basement faults, while produces because parallel tectonic movement causes collision Arabian Plate Eurasian Plate. Consequently, special strain pattern was formed reservoir quality crest Mishrif Yamama Formations best. axis has Boomerang shape, whereas it almost straight from south center structure, then tends NW with different deviations over formations. This direction may be anticlockwise rotation motion. results revealed that trap activities; Hormuz structures, reactivated Basement Collision Plates. intensity activities maybe less than surrounding Oilfields, therefore, formation's depth deeper adjacent Oilfields.
