West Africa Among World’s Most Expensive Regions for Oil Drilling – Deloitte Report
West Africa has emerged as one of the most expensive regions in the world for oil exploration and drilling, according to Deloitte’s 2025 West Africa Oil and Gas Outlook. The report paints a concerning picture for regional producers, especially Nigeria, highlighting the growing difficulty of staying globally competitive amid rising operational costs, complex local content rules, and persistent security challenges.
Deloitte’s analysis revealed that the region’s elevated drilling costs stem largely from endemic security issues, particularly in Nigeria’s Niger Delta. Expatriate roles in these high-risk zones attract significant premiums, driving up overall project expenses. These premiums, according to the report, often increase operational costs without necessarily yielding improved productivity or efficiency. The elevated security risk in the Niger Delta means expatriate roles are more expensive to fill, and these premiums add significantly to project costs, often without a corresponding return in productivity or efficiency.
The report further emphasized that these challenges have created a cost environment that makes it increasingly difficult for West African oil producers to compete with peers in other regions where production costs are considerably lower.
While local content regulations were originally introduced to empower domestic industries and promote capacity-building, Deloitte’s findings suggest they have become a major contributor to inflated project costs. Local content rules, while necessary for domestic capacity-building, can further inflate costs when required inputs or services are not readily available in the domestic market. This mismatch between policy intent and industrial capacity has forced companies to spend more on procurement. The report described a recurring pattern in which oil projects first attempt to source locally but are later forced to re-procure from offshore suppliers when local delivery fails.
To bridge these gaps, some companies reportedly rely on middlemen or form alliances to meet stringent local content requirements. However, this workaround has led to duplicated spending and inefficiencies that ultimately push costs even higher. Deloitte observed that policy inefficiencies and overly complex contracting processes remain key obstacles in reducing costs across the sector.
In response, the Nigerian government has taken steps to address these bottlenecks. The report disclosed that the Nigerian president recently issued executive orders to cut through complex procurement processes and local content rules. These reforms are expected to streamline bureaucracy, attract more investors, and create a more enabling environment for oil producers. However, Deloitte analysts caution that such policy changes will take time to yield measurable results unless supported by consistent implementation and collaboration across the industry.
Facing shrinking profit margins and intense competition from lower-cost producers globally, West African oil companies are increasingly rethinking their operating models. Deloitte Consulting teams working with firms in the region confirm a notable shift towards digital transformation. Producers are now investing heavily in technology and data analytics to enhance efficiency, optimize operations, and unlock cost savings across finance, logistics, and supply chain functions. Companies are implementing digital tools to improve visibility, manage risks, and minimize waste, with digitalization emerging as a key enabler in reducing costs and driving operational resilience.
This technological pivot aligns with a global trend where oil majors are leveraging automation, predictive analytics, and remote monitoring to cut costs and increase output in volatile markets. Despite efforts from both governments and industry players, Deloitte’s findings underscore that West Africa’s high cost of drilling is not merely a technical issue but also a structural and policy problem. A portion of the premium is a policy problem, one that requires government action to simplify contracting and reduce avoidable inefficiencies, while attempting to support local supply chains.
Experts believe that without decisive reforms, the region risks losing out on critical investment opportunities to emerging oil frontiers like Guyana and Brazil, where exploration costs are significantly lower. West Africa’s oil sector remains a vital source of revenue and employment for countries like Nigeria, Ghana, and Angola. However, with the global energy transition gaining pace and renewable alternatives becoming more attractive, the pressure to enhance efficiency and reduce costs has never been greater.
Analysts argue that the future competitiveness of the region depends on a balanced approach, where governments streamline policies and companies embrace innovation without compromising on sustainability and local participation. Deloitte’s 2025 outlook makes clear that West Africa’s oil producers face a defining moment: either adapt to the new energy economics or risk being priced out of the global market.
