Professor Upul Premarathne, an expert in Oceanography and Marine Geology at the University of Ruhuna, emphasizes that Sri Lanka's land areas are not promising for offshore petroleum exploration. This is due to the lack of sedimentary basins with sufficient thickness, typically over three kilometres, necessary for the formation of commercial petroleum deposits.
Consequently, exploration efforts have primarily concentrated on offshore sedimentary basins, notably the Cauvery and Mannar basins. The Cauvery Basin, situated off Sri Lanka's northern and northwestern coast, and the Mannar Basin, located south of Mannar Island on the western and southwestern coast, are both shared with India. The Mannar Basin has garnered more attention due to its geological suitability and the discovery of natural gas through exploration wells Dorado and Barracuda in 2011.
While the potential for crude oil exists, establishing a commercially viable petroleum field requires further investigation into factors such as the size, quality, and recoverable volume of hydrocarbons, as well as production rates and reservoir characteristics.
