• Block 18 is located north of Sudan approximately 550 km from Khartoum the capital city of Sudan, with a total area of 145902 Km2 (Fig 1).
• The block can be accessed through Dongola airport or known paved road.
• The main sedimentary basin in the Block is Abyad Basin (Fig 2).
• The configuration of the basin is similar to that of Misaha, Salima & Gabgaba basins in Block 14&KomOmbo (Egypt); the latter is a petroleum producing basin.
• Salima and/ or Gabgaba could represent the northern extension of a series of pull-apart basins which constitutes the KomOmbo, Gabgaba&Salima basins.
• The sedimentary fill ranges in depositional setting & age from shallow marine Silurian (?) through continental Permo-Triassic, Jurassic, shallow marine late Cretaceous and marine Tertiary carbonate &cherts (Fig 3).
• Shale sequences at the peripheries of the Abyad Basin indicate presence of potential source which embodies possible reservoirs of turbidite sands.
• As result of recent airborne survey of satellite study conducted 2013, confirmed the presence of Abayd sedimentary basin and considered as
