Integrated petrophysical and geological characterization for the Sidi Salem-Wakar sandstones, off-shore Nile Delta, Egypt

摘要

The present work provides a preliminary study to clarify the geological setting and petrophysical potential of the offshore Temsah gas field, which is located as a NW-SE trending anticlinal structure. In the Temsah gas field, the main target is the Serravallian Sidi Salem sandstones while the second target is the Tortonian Wakar Formation. The Sidi Salem Formation produces gas and condensates from three main sand lobes, while Wakar Formation produces from some sand interbeds. The seismic velocity in Temsah gas field was a major problem due to the complexity of the structural and stratigraphic setting, and the existence of a strong pattern of multiples generated by the Rosetta evaporites at the top of the Miocene sequence. In the present study, an integrated interpretation was applied for the available well logs and the subsurface geological data as well as some available seismic sections.
