Interpretation of 2D Seismic Data of Shurau and Sheikh Alas Formations in Ismail Area, Northern Iraq

The 2D seismic reflection data were used to study the structure of Shurau and Sheikh Alas formations (Oligocene) in Ismail area, northern Iraq. horizons reflectors identified based on well logs through a synthetic seismogram construction. Two-Way Time, velocity depth maps two coinciding obtained. A Great coincidence was noticed between identical formations. Main closure (syncline) trending NE-SE detected at southwestern part syncline is associated with many anticlines same trend. Bai Hassan appeared southeast while some northeastern Qara chauq area. features mostly NW-SE local variations may be due transversal faults.
