Exploration began in 1948 when Sinchair Oil, connoco and Agin (now ENI) discovered eight petroleum basins: daban; Migiurtinia; Mudugh; Mogadishu; El-Wak Mandera; Ogaden; and Chismajo and Lamu Basin – with columns of five-six kilometres in several area, and ranging in age from Jurassic or Triassic to Tertiary (several million years ago). Followed petroleum exploration commenced in 1950s as the country was believed to be a potential extension of the large Arabian oil province In 1950-1990, Somalia encouraged investments, and international oil companies including ExxonMobil, ConocoPhillips, BP, Shell, Chevron, and ENI all held large concession agreements in the country Only Royal Dutch and ExxonMobil remain in concessions holders with a 60,000 km2 of offshore Somalia. Shell and ExxonMobil continue paying the surface rental. The force majeure is going to die when Somalia signs the PSA. Starting from 15th of February when Ministry of Petroleum signed Coastline PSA, no more force majeure is in place. Somalia is going to benefit offshore blocks when PSAs Agreement with Coastline is in place and exploration and development Starting.
