THE NIGERIAN EXTENDED CONTINENTAL SHELF PROJECT AND ITS IMPLICATIONS FOR CROSS RIVER STATE AND THE WESTERN BAKASSI MARITIME CORRIDOR.

By John Gaul Lebo

The Nigerian Extended Continental Shelf (ECS) Project is one of Nigeria's most significant maritime and strategic achievements since the adoption of the United Nations Convention on the Law of the Sea.

Following years of hydrographic, geological, geophysical and bathymetric studies, the Commission on the Limits of the Continental Shelf approved Nigeria's submission, granting the country sovereign rights over approximately 16,300 square kilometres of additional seabed beyond the traditional 200-nautical-mile continental shelf.

The approval, formally communicated in 2023 and presented to the Federal Government in 2024, significantly expands Nigeria's jurisdiction over seabed resources while remaining consistent with international maritime law.

The extended continental shelf does not enlarge Nigeria's territorial waters but grants exclusive sovereign rights to explore and exploit the seabed and subsoil, including petroleum, natural gas, polymetallic minerals, gas hydrates, submarine infrastructure and other non-living resources. It also strengthens Nigeria's strategic position within the Gulf of Guinea and enhances maritime security, scientific research and the blue economy.

Nigeria's Extended Continental Shelf (ECS) Project significantly enhances the strategic importance of Cross River State because the state lies along Nigeria's southeastern maritime gateway through the Cross River Estuary and the Western Bakassi maritime corridor.

Cross River's elongated continental shelf and natural littoral access position it as a key component of Nigeria's offshore maritime domain, supporting petroleum exploration, maritime trade, fisheries, security operations and the emerging blue economy.

The ECS also provides valuable scientific and hydrographic evidence that strengthens understanding of the offshore petroleum systems associated with Cross River, including the transboundary reservoirs in OML 114 (Abana Field) and OML 115 (Ekanga and Zafiro Fields).

This reinforces the strategic significance of the state's offshore basin and supports future investments in offshore energy infrastructure, including the proposed Bakassi Deep-Sea Port and related logistics facilities.

For Cross River State, the ECS approval has strategic implications because the state occupies Nigeria's southeastern maritime gateway through the Western Bakassi maritime corridor, the Cross River Estuary and the Calabar Flank.

These areas form part of Nigeria's natural continental margin extending into the Gulf of Guinea and constitute one of the country's most prospective offshore hydrocarbon provinces.

The Western Bakassi maritime corridor is particularly important because it hosts several offshore petroleum assets, including OML 114 (Abana Field) and OML 115 (Ekanga and Zafiro Fields). These fields are associated with transboundary petroleum reservoirs that extend across the maritime boundary between Nigeria and Equatorial Guinea.

Such reservoirs are governed internationally by the principle of cooperative development (unitization), under which adjoining states jointly manage petroleum deposits that straddle international boundaries.

In the case of OML 114 (Abana Field) and OML 115 (Ekanga–Zafiro), geological studies have long indicated that several producing reservoirs extend across maritime limits.

Consequently, accurate hydrographic surveys, internationally recognized coordinates and lawful maritime boundary delimitation become critical for determining resource ownership, production allocation and revenue entitlement.

The Nigerian Extended Continental Shelf Project therefore provides an important scientific and legal platform for strengthening Nigeria's offshore claims. Although the ECS process does not itself determine maritime boundaries between neighbouring states, it supplies internationally accepted geological and bathymetric evidence that supports Nigeria's long-term management of offshore resources and enhances planning for future exploration beyond existing producing fields.

For Cross River State, the project reinforces several strategic opportunities, including recognition of the state's role within Nigeria's southeastern offshore petroleum province, stronger technical justification for continued evaluation of offshore hydrocarbon resources associated with the Western Bakassi maritime corridor, enhanced prospects for offshore exploration and deep-water investment, and greater justification for developing the proposed Bakassi Deep-Sea Port as a logistics hub supporting offshore oil and gas operations.

In conclusion, the Nigerian Extended Continental Shelf Project represents a major national maritime achievement with profound implications for Nigeria's economic future.

For Cross River State, it strengthens the strategic importance of the Western Bakassi maritime corridor and highlights the continuing significance of offshore assets such as OML 114 (Abana) and OML 115 (Ekanga and Zafiro), including their transboundary reservoirs.

While questions relating to maritime boundaries, offshore resource attribution and derivation remain subject to Nigeria's constitutional, statutory and international legal frameworks, the ECS provides a stronger scientific and technical foundation for future offshore resource development and reinforces Nigeria's sovereign rights over its expanded continental shelf.
