Multi-Dimensional Seismic Attributes and Density Models of the Hydrocarbon Plays Inferred from Seismic Reflection and Bouguer Gravity Data at the Northern Region of West El-Qantara in Nile Delta Basin, Northern Egypt

Abstract

Onshore, the Nile Delta has experienced a rigorous and successful exploration campaign during the last few years. This is because of the importance of the Nile Delta basin economically as a gas bearing basin. Since 2007, Dana Gas Egypt Limited explored many Pliocene and Miocene Gas discoveries in West El Qantara concession located in the eastern Nile Delta. The present study is in West El-Qantara concession and is located in the eastern on-shore part of the Nile Delta, south of El Manzala Lake. The study area lies between Latitudes 31o 02' 00" & 31 o 08' 00" N and Longitudes 31o 46' 00" & 32o 02' 00" E. Gravity method is commonly integrated with seismic for the deep seated structures imaging for the purpose of understanding the pre-existing structures and how they develop with time. This has a great impact in tracking the migration of hydrocarbon fluids and their entrapments. The 2D density (crustal) models were constructed and they illustrated the distribution of the basement and the shallow sedimentary cover which is containing the petroleum system elements (source rocks, seal rocks, and cap rocks) in relation to a specific structural trap.
