Summit Oil International Limited is a pioneer oil company that was founded in 1990 by Chief Moshood Abiola to embrace the independent indigenous upstream oil company concept. OPL 205, located largely in the Anambra Basin on the north edge of the Niger Delta, was granted to Summit in 1990.

Summit established a slim but efficient staff of 50 professionals who operated the full range of exploration activity and moved the Company rapidly towards planned early production. Summit acquired 2D seismic in 1991 and drilled the first exploration well in the first quarter of 1992, which discovered the Otien Field on OPL 205 – arguably the first oil discovery ever by a private indigenous company in the Federal Republic of Nigeria.
