Abstract

This paper presents the evaluations of the reservoir characterization of the Lower Miocene Euphrates, and Jeribe carbonate formations that have been selected for this study in Kor Mor Gasfield in Northeastern Iraq. The Euphrates ranged in thickness between 30 and 65, and Jeribe 30 and 50m in this field, and they are overlain by a thick evaporate cap rock of the Fatha Formation. The two formations are separated by the thin evaporate rock unit of the Dhiban Formation


The full set of log data for the well Km-9 was used in addition to some general data derived from other eight wells (Km-1 to Km-8). The log data have been used in evaluating the reservoir properties of the two rock units. The detected lithologies from the available mud log and well reports showed that the two formations mostly dolostone and dolomitic limestone were dominated. From the log data, different types of reservoir properties (clay content, clay types, porosity, and fracture index,) have been estimated. The average porosity of the Euphrates reservoir is around of 0.15, and the Jeribe 0.10, the secondary porosity makes a significant fraction of porosity in both units.
