The boundary set out by the text of the treaty does not demarcate the entire Equatorial Guinea – Nigeria treaty. When the treaty was signed, the International Court of Justice (ICJ) was hearing a case about a maritime dispute between Cameroon and Nigeria; because the result of that case would affect the maritime boundaries in the Gulf of Guinea, it was decided to leave the complete delimitation of the boundary until after the ICJ case concluded.
The boundary defined in the treaty runs through the Bight of Bonny and separates the Nigerian mainland from Equatorial Guinea's Bioko Island. The boundary consists of nine straight-line maritime segments defined by ten individual coordinate points. Rather than adopting an equidistant line between the two countries, the treaty takes into account both countries' established economic interests in the Gulf of Guinea, including existing oil wells, oil drilling installations, and existing resource consent licences.
The full name of the treaty is Treaty between the Federal Republic of Nigeria and the Republic of Equatorial Guinea concerning their maritime boundary.
