Structural and Stratigraphic Evolution of Mishrif and Ratawi Formations in Safawi Oil Field, Southern Iraq

Abstract

The current study intends to track and choose geological locations with prospective hydrocarbons at the Ratawi and Mishrif formation levels, in addition to looking for the possibility of showing stratigraphic trapping and assessing probable hydrocarbon resources. The research area is located in southwestern Iraq, within the administrative borders of the Najaf Governorate, in the Western Desert region. Several two-dimensional seismic survey programs Takhaded, Safawi, Qurnain, Glissan first stage and their lines TI, QN, and 1GN were employed, as well as various Glissan-Fourth stage survey lines 4GN. Two systems of faults have been identified within the study area. By performing the Instantaneous phase attribute, also there are two stratigraphic phenomena have been delineated within the Mishrif and Ratawi formations.
