ABSTRACT: Suakin-1 and Suakin-2 wells are in the Sudanese Red Sea segment where the
hydrocarbon generation had been proved by previous studies, however, no
reasonable reserve was evidenced due to the complexities of the surrounding
salt structures. Six seismic lines were tied to Suakin-1 and -2 to delineate
the controlling salt tectonics. The salt evacuation (Roho) and other salt
bodies were recognized and matched with similar salt structures in analogous
stratigraphic conditions as the Gulf of Mexico and Angola margin. While a
previous inconsistent interpretation in the study area marked
the high amplitude horizon of the Lower Zeit formation as the top of the
Dungunab formation. Three seismic features indicated the presence of salt dome
(autochthonous): velocity pull-up, dragging of the sedimentary layers forming
mini basins around the third feature, which is the relative transparency of the
seismic signal in two piercing like bodies. This interpretation similarly
demarcated that the salt escaped east-wards, thus the mapped welded salt is
believed to be formed after the salt evacuation. A 3D seismic with a far offset
and wide range of azimuth is recommended for detailed imaging.
