Abstract
Bai-Hassan Oil Field is considered as one of the important north Iraq oil fields. The oil field of Bai-Hassan is faraway about 40 km to the northwest of Kirkuk City. The field consists of two domes (in NW- SE direction) Kithka Dome and Dauod Dome separated by a narrow saddle called Shashal saddle. The current study is focused on microfacies analysis to build 3D reservoir models and petrophysical properties of Palani Formation (Early Oligocene) and Baba, Bajawan and Tarjil formations (Middle Oligocene). In the present study, several types of well-logs obtained from BH-20, BH-39, BH-53, BH-89, BH-91, BH-92, and BH-122 wells which including gamma-ray (GR), neutron (NPHI), density (ROHB), sonic (DT), spontaneous potential (SP) and resistivity (LLD, MSFL) well-logs were used in order to determine and study of reservoir characterization to explain different parameters including lithology with contacts identifications, total (PHIT) and effective (PHIE) porosities, permeability, water saturation (SW) and hydrocarbons saturation (Sh), of Oligocene succession in the Bai-Hassan Oil Field within Zagros basin, northern Iraq. The analysis of the results showed that the Kathka dome area compared to the Dauod dome area is better in terms of petrophysical properties as well as in terms of its content of hydrocarbon groups.
