• Block 19 is located in Westren Sudan with area of 132024 Km²(Fig 1).
• The Block is considered as frontier exploration area.
• The geological outcrop of block-19 is made up of Paleozoic and basement, while the sub-surface contains Mesozoic sediments.
• Generally, its analogous in geology are the neighboring Kufra (SE Libya), Murdi (Chad), and Dakhla (SW) basins.
• Distinct sedimentary basin has been identified, namely; the South Wadi Howar as potential for hydrocarbon exploration (Fig 2).
• The basin quite virgin with very little data; however the similarities in its origin, geology, and tectonic histories render it a tremendous chance for HC occurrence.
• There are indications from recent gravity data that the S. Wadi Howar basin could reach more than 5 km depth.
