| Abstract | ||
| This study aims to determine and evaluate the petrophysical characteristics of the Khasib Formation, which represents the main oil-producing reservoir in the East Baghdad oilfield. To accomplish the aim of the study, the log data for five wells have been interpreted using the Schlumberger Techlog 2015.3 software. The main lithology of the Khasib Formation has been determined as limestone based on the interpretation of neutron, density, and sonic logs and using the M-N cross plot method. The shale volume was determined based on the gamma ray log, and the results showed that the shale volume in the Khasib Formation ranges from about 15% to about 27%, and this value increases toward the top of the formation. The total porosity of the Khasib Formation has been determined based on the density and neutron logs, and it is value ranges from about 12% to 23%. The effective porosity was calculated depending on the relationship between the total porosity and shale volume, and the value of this type of porosity ranges from 8% to 18%. The study showed that the B and C units of the Khasib Formation represent the best hydrocarbon-bearing zones, where these units are characterized by high values of effective porosity and oil saturation. | ||
