Petrophysical evaluation of the Messinian Abu Madi Formation in Salma delta gas field, northeastern onshore Nile Delta, Egypt

An integrated sedimentological, rock typing, image logs, and artificial neural networks analysis for reservoir quality assessment of the heterogeneous fluvial-deltaic Messinian Abu Madi reservoirs, Salma field, onshore East Nile Delta, Egypt

“…Rock-typing is an integrated multi-proxy approach for reservoir characterization and field production optimization that employs geological, petrophysical, and engineering data to better-characterize heterogenous reservoir units and define their potential performance (Guo et al, 2005;Gomes et al, 2008;Al-Farisi et al, 2009;Masalmeh et al, 2012;Skalinski & Kenter, 2014;Nabawy et al, 2018b;Radwan et al, 2021;Barakat, 2022;Nabawy et al, 2022a,b). Most advanced rock typing techniques, such as the 'Winland's R35' method (Pittman, 1992), the reservoir quality index (RQI) determination (Leverett, 1941), and the flow zone indicator (FZI) calculation for flow unit identification, rely on data from core measurements (e.g., Amaefule et al, 1993;El-Sharawya et al, 2020;El-Adl et al, 2021).…”
