ABSTRACT: Mediterranean Sea considered
as a main hydrocarbon province in Egypt as a huge reservoirs have been discovered
till now. Port Fouad marine is a gas and condensate field located in Eastern Mediterranean
Sea about 30 KM off Egyptian coast, in a water
depth of about 30 m. The Concession is operated by PETROBEL on behalf of
Petrosaid (Port Said Petroleum Company). The field was put on production on April
1996, from the Miocene turbidities sands of Wakar Formation plus Pilocene Kafr EL
Sheikh Formation. Darfeel field is located within Port Fouad Concession, seven wells
have been drilled till now and producing from Pliocene section (Kafr El Sheikh Formation).
Pliocene is the main reservoir in Darfeel field which characterized by turbidities
sand stone. The aim of this work is to identify the distribution of turbidities
sand and characterize sand reservoirs using AVO
(amplitude verses offset) and seismic attributes
techniques. The workflow is starting from conventional seismic interpretation,
maps (time, depth, and amplitude), depositional environments, and finally structure
setting. In addition to use some of unconventional
seismic interpretation such as seismic attributes. AVO analysis and attributes
had been applied in a temp of differentiate between gas sand reservoirs and non-gas
reservoirs. The final result aid to identify the reservoir distribution and characterization
of sand reservoirs through the field. So, the use of different seismic
techniques is powerful techniques in identifying reservoir distribution.
