The development of the petroleum industry in Nigeria started several years ago. The first attempt made towards oil expoloration was in 1908 by a German company called Butman Corporation. This was closely followed in 1937 by Shell D ‘Aery, an Anglo-Dutch company.

By 1956, Shell B.P. embarked on a more economic production of petroleum in the Niger Delta region of Nigeria.

 It was in this year 1956 that Shell B.P. discovered its first commercial crude oil in the country at Oloibiri in the present Rivers State. In 1958, full scale production took off.

Later, many other companies such as Agip Oil and Gulf (now Chevron), joined in the exploration of crude oil. By 1960, when Nigsria became independent, the volume of output of crude oil was just about six milliom barrels. By 1965, crude petroleum production had reached about 100 million barrels. The civil war between 1967 and 1970 slowed down production. Ai the end of the civil war, crude oil production was about 197 million barrels.
