Structural Study of East Baghdad Oil Field by Using Select Reflective Seismic Sections
The East Baghdad field was studied by using three seismic reflection sections with a direction of northeast-southwest perpendicular to the axis of anticline, with axis direction is northwestsoutheast.
As these sections of different depths are clearly distinguished by the reflexive geophysical characteristics between good, medium and bad, as the regularity or irregularity of the geometry of the surfaces of the reflectors reflects the different structural and stratigraphic changes in the study area. Through the study of the seismic reflection sections of the studied area, we find that the region is affected by complex and large tectonic factors. These represented by the strike slip fault surfaces of the positive flower structure that penetrate most of the Mesozoic sediments, represented by the Jurassic and Cretaceous periods, and the Cenozoic era which represented by the Tertiary era.
This reflects the tectonic development of the study area, which is directly related to the tectonic movement of the Arab plate and its collision with the Iranian and Turkish plate, as this collision is the causing for the generation of the most faults.
Most of the geological structures formed (fractures, faults, and folds) resulted from the rotational movement of the Arab plate clockwise, and affected by the Alpine movement that occurred in the Tertiary period. Evidence of this movement is the direction of the axis of the fold northwest-southeast parallel to the direction of the structures of the Zagros mountain range.
