Abstract

This study aims to assess the formation evaluation of the Jeribe Formation in Hamrin oilfield. The present study involved four selected wells of (Early- Mid Miocene) Jeribe Formation in Hamrin structure-Allas field; HR-2, HR-8, HR-9, and HR-16 located North of Iraq. The work deals with the available data that includes the most required information to improve such studies. Techlog Software V.2015 was used to carry out a reliable calculation of petrophysical properties utilizing conventional logs to determine the reservoir characteristics (lithology, porosity, and saturation). The computed CPI (software resulted) based on log information divided the Jeribe reservoir into two reservoir units (Jr-1 and Jr-2) within the studied wells. The calculated effective porosity and water saturation revealed that the unit Jr-1 in Hamrin- Allas oil field contains hydrocarbons at wells HR-2 and HR-16. In contrast, unit Jr-2 was 100% water-saturated along the selected well depths at wells HR-2, HR-8, HR-9, and HR-16.
