The Nile Delta and its offshore area is rapidly emerging as a major gas province in the Mediterranean region. Offshore exploration using high-quality 3D seismic data helped in achieving significant discoverers in the last two decades. The giant Zohr discovery made in 2015 by the Italian oil company ENI offshore Egypt, and the Glaucus discovery made by ExxonMobil offshore Cyprus in 2019 are a proof on the significant remaining yet-to-find hydrocarbon potential of the East Mediterranean Basin.
Deep-water channel systems and turbidites plays have been the primary focus of hydrocarbon exploration and development. The prolific Pliocene slope turbidite canyon-channels offshore Egypt are restricted to the Nile Delta cone. Scarab field is one of at least nine deep-water Pliocene slope canyon-channel systems in the WDDM concession that were found in the expansive slope setting in a period of progradation of El-Wastani Formation (El-Mowafy et al., 2019).
This study is focused on characterizing bypassed subtle stratigraphic traps encountered in the upper Pliocene El-Wastani Formation in the Scarab gas brownfield (El-Mowafy et al., 2019). These bypassed traps are important architectural elements of the submarine deep-water slope turbidite channel systems.
Simultaneous seismic inversion was applied over Scarab field with the purpose of evaluating the hydrocarbon potential of newly identified stratigraphic traps. Using the inverted impedance and Vp/Vs volumes, FMI facies logs, Bayesian facies classification was applied to separate thin- and thick-bedded gas-sand facies from shale. Facies classification was focused on two prospective bypassed stratigraphic traps: the Upper Scarab Channel Remnant Levees (RML and RSL) and the Lower Scarab Channel Lateral Accretion Packages (LAPs). A development well location is proposed to validate the interpreted gas-sand reservoirs in the shallower RML and the deeper LAPs stratigraphic traps. The results suggest that application of the seismic inversion and facies classification led to reliable inferences likely to have positive impact on field development, potential reserves growth and consequently boosting gas production.
Speaker Biography: Dr. Hamed El-Mowafy, NeuEra GeoServices, LLC
Dr. Hamed El-Mowafy received a B.Sc. in geology and an M.Sc. in petroleum geology from Al-Azhar University in Cairo, Egypt, and a Ph.D. in geosciences from the University of Tulsa, Oklahoma. Currently he is a Senior Geoscientist Consultant with NeuEra GeoServices based in Houston, where he conducted several projects in multiple sedimentary basins around the world, mainly East Mediterranean, Atlantic margins and the Gulf of Mexico basins. He Spent 12 years with Apache Corporation in Houston and Apache Egypt where he participated in multiple oil and gas discoveries and created multiple drillable prospects in Egypt and US. He has extensive experience in various areas of petroleum exploration and production. His professional interests include seismic and sequence stratigraphy, interpretation of seismic data, and reservoir characterization.
