Subsurface Structural Study by Using Seismic Section for the Rumaila Oilfield-Southern Iraq

Abstract

Through the use of reflected seismic section, which gives a lot of details about the subsurface features and geological structures, it is useful to use this section to explain the subsurface of geological structures of the Rumaila oilfield, which is located southwest of Basra. the interpretation of this section shows strike slip faults, both positive and negative tree (Positive flower structure) and (Negative flower structure) and that the direction of these rifts were found to be in North - South. The presence of these types of faults indicates the horizontal stresses affect the study area, and that these faults cut Jurassic and Cretaceous sediments and their effect reached the Tertiary sediments.
