Said bin Taimur
A geological survey of the country in 1925 by the D'Arcy Exploration Company found no conclusive evidence of oil. Twelve years later, when American geologists began intensively searching for oil in neighboring Saudi Arabia, Sultan Said bin Taimur granted a 75-year concession for central Oman to the Iraq Petroleum Company (IPC), and a separate concession for the province of Dhofar. Pausing only for the Second World War, exploration for oil was under way in Oman.
