Abstract

Seismic sequence stratigraphy has come of age, and it is a tool every explorationist
must Master, It is essential for regional and local exploration studies, for seismic and
reservoir evaluation. The Pliocene system considered as the primary prospect for
hydrocarbon exploration in the Mediterranean province. This study is expected to establish
framework and new time scale for the Pliocene sequences in the Mediterranean. The
sequence Stratigraphic framework is based on the well biostratigraphy and logs used to
calibrate the seismostrtaigraphic architecture.
The biostratigraphic framework of the Mediterranean is based on quantitative analysis
of the foraminifera and nano planktons. The Pliocene section is dated by both foraminifera
(N19 to N21) and Nanoplanktons (NN12b to NN19a). The seismic sequence Stratigraphic
analysis approach, the Pleistocene, Pliocene and Pliocene-Miocene boundary section of the
Mediterranean of Egypt is divided into seven third order cycles (3.10 to 3.4) with time
range (0.8 to 5.6 M.y). This cycles sub divided into fourth order sub cycles (3.10A to 3.4B).
So the sand patches of the study area distribute in the Upper Pliocene (Base El Wastani
Formation) in cycle 3.8 and Late Miocene, Upper Messeinian) in cycle 3.5. The study area
changed from shelf to delta channels then converted to marine channels northward. The
depositional environment was shown to be delta front mouth bars on the shore face to the
South. Then, this part was sloped to the North with the start of valley cut and stage of sub
marine erosion and slumps. The valley fills deposits and at the extreme North. The
reservoir of Pliocene age represented by basin floor fan and deep seated channels which are
deposited as thick Turbidite sequences.
The seismic startigraphic used to decipher the variations implied in the seismic
response and wave characterestics to comparable geologic information regarding lithofacies
and depositional environment). The seismic facies of El Wastani and Kafr El Sheikh
Formations exhibited the prevalence of divergent and parallel to sub parallel patterns,
changes latteraly to bright spots indicating gas-bearing sand as the form of fans or sand
channels. This deep water sands are the primary reservoirs in the Mediterranean sea due to
high porosity and permeability.
