Petrographical and Petrophysical Features of the Jeribe Formation at the Khabaz Oil Field, Kirkuk, Northern Iraq

Abstract

The present study deals with the Jeribe Formation (Middle Miocene) in well Khabaz-17 (Long. 44° 11' 27" E ; Lat. 35° 25' 16" N) belonging to Khabaz oil field in Kirkuk area, northern Iraq. Generally, the lithology of Jeribe Formation is homogeneous and it consists of limestone, dolomite, dolomitic limestone, gypsum, and nodules of chert with a thickness of about 36 m at depth 645-681 m. Petrographically, 50 thin sections have been prepared and studied under polarized microscope. Based on this, they appeared to consists mainly of genus benthonic foraminifera (Borelis melo curdica, Miliolids, Peneroplis, Nummulites and Rotalids) where they characterized by the good keeping, large volume and the thickness of the wall. On the other hand, less common fauna included Gastropods, Pelecypods, Echinodermata fragments, Algae, Ostracods and many of bioclasts, as well as non-skeletal grains intraclasts and pisoids, while the ground mass mainly compose of a micrite and micro-sparite. Several diagentic processes affected the Jeribe formation which include mainly of dolomitization, cementation, micritization, dissolution, compaction, fracturing and other types of diagenetic such as neomorphism and bioturbation. Through the petrographic study the types of porosity were identified. While, the porosity ratios was determined from the density and the neutron logs. According to the results of these analyses, the porosity of Jeribe formation changes from 11.4% and 25.6%, with an average rate of 17.3%. These values are described as good porosity, and had probably been enhanced by some diagenetic processes by dolomitization and dissolution followed by secondary effects from tectonics activities.
