Conventional and Advanced Petrophysical Evaluation of Pliocene Sediments in Simian Field, Offshore Nile Delta, Egypt

Abstract

The study area is located approximately 120km NE of Alexandria, which lies offshore in the deep water (250-1500m) of the Nile Delta and bordered between latitudes 32º 16` & 32º 06`N and longitudes 30º 44` & 30º 56`E. Simian element is one of the major channel systems that make up the Mid-Pliocene submarine channel complex as mapped in the West Delta Deep marine concession. The materials used in this study include collection and description of the complete log sets from four wells in the study area, including the conventional logs; Gamma Ray (GR), Caliper, Deep and Shallow Laterolog resistivities (LLD, LLS), Micro-Spherically Focused log (MSFL), and porosity tools (Density, Neutron, and Sonic), also the advanced logs; Formation Micro Image (FMI), Combinable Magnetic Resonance (CMR), and Modular Dynamic Tester (MDT). The petrophysical interpretation showed that the effective porosity ranges from 21% to 25% and the water saturation ranges from 29% to 40%, and the volume of shale is from 16% to 29%. Generally, the distribution of the petrophysical parameters increase from the core of the channel toward its levee along the channel axis of the study area. The optimum location for the proposed wells is the southeastern parts of the field, where the lower shale volume and net to gross, and the higher porosity and hydrocarbon saturation values are of the combination of structural amplitude map and petrophysical maps the best drilling for future consideration helped to locate new locations.

Reservoir characterization of the Messinian Abu Madi reservoir in South Abu El Naga gas field, Onshore Nile Delta, Egypt

“…Consequently, it remains a primary focus for ongoing and future exploration endeavors aimed at gas production (Abd El-Aal et al, 2018). Recent groundbreaking discoveries, such as the Zohr gas field, have underscored the region's remarkable potential, effectively meeting domestic natural gas demands and propelling Egypt to become a major gas exporter in North Africa and the Middle East (El-Mahdy et al, 2017).…”
