Wood Mackenzie Flags 300-Billion-Barrel Supply Gap, Majors Ramp Up Deepwater Exploration
According to World Oil, a new Wood Mackenzie report warns that currently producing and sanctioned fields will cover only about 700 billion barrels of liquids through mid-century, leaving a 300-billion-barrel gap by 2050. Existing asset production is projected to decline nearly 40% between 2025 and 2040. In response, major oil companies and national oil companies including Petrobras, PETRONAS, and TPAO are accelerating ultra-deepwater exploration in water depths exceeding 1,500 meters, with 23 high-impact wells targeted in 2026. Exploration spending has held steady at roughly $19 billion annually from 2021 to 2025.
What It Means for Subcontractors
- Sustained deepwater drilling campaigns mean continued demand for specialized field services, particularly offshore drilling support, subsea installation, and completion work across active basins.
- The projected 40% decline in existing asset production signals ongoing workover and field extension activity onshore and nearshore, keeping intervention and production services busy through the next decade.
- With 23 high-impact wells planned for 2026, service companies positioned in active exploration regions, including the Gulf of Mexico, West Africa, and Brazil, should expect competitive but real contracting opportunities.
