Structural Setting and Reservoir Characterization of Syn- Rift Facies, West Gebel El-Zeit Area, Gulf of Suez, Egypt

Abstract

The study area including Al Amir and Geyad fields (onshore Northwest Gemsa) is located in West Gebel El Zeit area, covering an area of about 39 km2 and 26.4 km2.  The study area is a PetroAmir concession (Geyad and Al Amir concessions) which includes nine wells from north to south ; Shehab- 1x, Geyad-2X, Geyad-1X, Al Amir-1X, Al Amir SE-1X and St, Al Amir SE-2X, Al amir SE-3X, Al Amir SE-4X, Al Amir SE-5X and Al Amir SE-6X.  The raw data of the selected wells, include the formation tops MD (Measured depths), TVDSS (True vertical subsea depth) and TD (total drilling depth). The Stratigraphic framework was concentrated on the four main reservoir units (Nukhul, Rudeis, Kareem and Belayim formations). The used wireline logs are; Gamma-ray log(GR), Neutron porosity(NPHI), Bulk density(RHOB), Photoelectric(PE), Dual- Laterolog (deep)(LLD), Dual-Laterolog (shallow) (LLS) and Microspherically Focused (MSFL).  Based on the high resolution biostratigraphic zonation of the studied wells the definition of foraminiferal and calcareous nannoplankton zones have been adopted for the study sequences. These have also been calibrated with the equivalent biostratigraphic schemes of the Mediterranean basin. There are some wells with no bio-data and accordingly, their cyclolog pattern and cycles definition have been interpreted and correlated with the results reached in other wells.
