A scientific study at the University of Basrah looking at facian analysis and the sedimentary environment of the Saadi Formation

Prof. Dr. Mohanned Hamid Al-Jabri, Adyan Ali Myzban and Methaq K. Al_Jafar published a paper entitled Microfacies analysis and Depositional Environments of lower Sa’adi Formation, Southern Iraq

          

in the Iraqi Geological Journal, which is indexed in Scopus/Web of Science database. the study aims to determining the depositional environment, reservoir behavior, and predicting the favorable environment with a higher oil production rat. According to petrographic studies, the lower Sa‘adi Formation has 12 carbonate microfacies associated with three facies: middle ramp in unit C and lower unit B, inner ramp open marine in upper unit B and lower unit A, and shoal in upper unit A. Thus, these facies reflected the system of shallowing upwards, which these facies of this paleoenvironment are evidence of the regression in the Lower Sa’adi Formation. The deposition environment was articulated as part of the homocline rampThe reservoir quality with porosity and permeability distribution is the best in the inner ramp facies (Unit A) of lower Sa’adi Formation.
