Abstract
In the Gulf of Suez, the cumulative oil production from sandstone and carbonate reservoir intervals had various ages and was proven in Amer Oil Field. Our study aims to investigate the subsurface geology and hydrocarbon potential of the Miocene sequence at Amer Field, Gulf of Suez through constructing the reservoir characterization and depositional setting of Belayim Formation of this field. This was carried out through the Kingdom software (IHS Markit version 2016) (Kingdome Software), Petrel (Version 2017) and Techlog (version 2015) also the structure contour maps are established on top of the selected rock units of Miocene Belayim Formation which was penetrated by four wells namely, Amer-26 in the south, Amer-12 in the north, and Amer-54 in the far north, where Amer-58 was derived as a deviated drilled well. The twenty seismic lines was picked to construct the top Belayim structural contour map’s 3D seismic data revealed a general fault pattern trending toward the NW – SE direction.
The Belayim Formation (which includes the Baba, Sidri, Feiran, and Hammam Faraun members) was formed during the Middle Miocene and marked the start of the main Miocene evaporitic cycle. The research region was penetrated by four wells namely, Amer-26 in the south, Amer-12 in the north, and Amer-54 in the far north, where Amer-58 was derived as a deviated drilled well. The top Belayim structural contour map’s 3D seismic data revealed a general fault pattern trending toward the NW – SE direction.
The petrophysical evaluation of the productive zone of Belayim Carbonate (Nullipore sediments of Hammam Faraun Member) in Amer wells nos. 12, 26, 54 and 58 reflect and 63.3 %, respectively. Schlumberger’s charts are applied in current study to obtain the lithologic characters and petrophysical parameters of the Belayim pay zone at Amer Field which is characterized by the predominance of reefal carbonates (mainly limestone). The net / gross map of Belayim reservoir revealed that, the dense reefal Limestone reached its maximum values at the northeastern (Amer-54 well) and southeastern parts (Amer-26 well) of Amer field, where it attained to 52.5 % and 54 %, respectively. However, there is a unformal decrease in the opposite directions at Amer-12 on the western side and Amer-58 in the northeastern one reaching 26.4% and 32.8, respectively.
The subsurface petrophysical evaluation of the Hammam Faraun Member, Belayim Formation at Amer Oil Field revealed: 1) an increase in net pay thickness towards the northeastern part of the field, 2) a gradual increase in effective porosity towards the central and western parts; 3) a decrease in clay volume towards the northeastern and southeastern parts; 4) a decrease in water saturation towards the northwestern parts; and 5) a gradual increase in hydrocarbon saturation towards the northeastern part of the studied oil field.
