Abstract

The present work focuses on well logs interpretation for evaluating the Middle Abu Roash G sand Member, and the Lower Abu Roash G sand Member in Abu Roash Formation in Hamra oil field. This study has been carried out by the integration and interpretation of the well-logging analysis and the 3-D seismic data of four wells distributed in the Hamra oil field.
The study results show that the Middle Abu Roash G sand Member has better reservoir characterization than the Lower Abu Roash sand Member. The estimated petrophysical parameters of the reservoir throughout the study area for the Middle Abu Roash G sand Member range between about 22% and 33 % for the effective porosity, and range between about 6 % and 12 % for shale volume, and range between about 34 % and 48 % for Water saturation, and while range in the Lower Abu Roash sand Member between about 16 % and 34 % for effective porosity and between about 4 % and 26% for shale volume, range between about 52 % and 100 % for Water saturation. All of these results indicate that Abu Roash G Formation in this field can be considered as good reservoir with high potential for oil production
