SOURCE ROCK EVALUATION AND HYDROCARBON CHARACTERIZATION OF ABU QIR OFFSHORE AREA, NILE DELTA, EGYPT
Yasmin Kadry Ali Mostafa;
Abstract
The Abu Qir area lies in the northwestern side of the Nile Delta region, the offshore Mediterranean Sea, between longitudes 30° 00´- 30° 24´E and latitudes 31° 18´- 31° 40´N.
The Nile Delta is one of the most promising provinces in Egypt due to its significant hydrocarbon potential. The Abu Qir basin is considered as one of three main sub-basins in the Nile Delta that has been formed due to the effect of the Serravalian tectonic movement during the Late Miocene. Patterns of sedimentation in the northern delta between the late Oligocene and the Pliocene were controlled by four reactivated faults named the Bardawil line, Qattara-Eratosthenes line, Pelusium line, and Hinge zone.
The sedimentary sequence penetrated by wells in the study area consists of thick Miocene-Pleistocene siliciclastics. The lithostratigraphy of the study area is represented by Miocene sediments (Qantara, Sidi Salem, and Abu Madi formations) and the Pliocene–Pleistocene sequences (Kafr El Sheikh, El Wastani, and Mit Ghamr formations), which are represented mainly by shale or clay with sandstone interbeds. Also, Qantara Formation (Early Miocene) is composed of calcareous marine shales and sandstones. In addition, the formation is overlain unconformably by the Sidi Salem Formation (Middle Miocene) which is dominated by shales with some sandstones facies, deposited under marine to fluvial condition. Moreover, it is unconformably overlain by Qawasim and/or Abu Madi formations. Moreover, these formations are overlain unconformably by Kafr El Sheikh Formation, which is composed of shales and sandstones. In addition, the thickness of the Kafr El Sheikh Formation increases towards offshore areas. Furthermore, Kafr El Sheikh Formation is overlain by El Wastani Formation (claystones and sandstones), which represent a transitional facies between the shelf facies of the Kafr El Sheikh Formation and the fluvio-deltaic facies of the overlying Mit Ghamr Formation.
