Oil and Natural Gas Corporation (ONGC) is gearing up for its largest-ever offshore exploration initiative, with plans to invest between $18 billion and $20 billion in hiring deepwater drilling rigs. The ambitious programme reflects the company’s strategic push to expand hydrocarbon exploration and strengthen India’s energy security. The move also aligns with the government’s Samudra Manthan mission, which aims to increase domestic oil and gas production by accelerating offshore exploration activities.
Major Investment in Deepwater Drilling
As part of the large-scale programme, ONGC has issued a global tender for deepwater drilling rigs, seeking a combination of drillships and semi-submersible rigs. The proposed contracts are expected to run for up to five years, indicating the long-term nature of the exploration plan. The initiative represents one of the most significant offshore investments by ONGC in recent years and highlights the company’s focus on unlocking untapped hydrocarbon resources in deep and ultra-deep waters.
Strong Industry Interest in Rig Contracts
The tender has already generated strong interest from both domestic and international drilling companies. A pre-bid meeting held in Mumbai on March 20 attracted participation from several major players in the offshore drilling sector. ONGC has set an ambitious timeline and plans to mobilise the drilling rigs within 80 days. The accelerated schedule reflects the urgency with which the company is seeking to expand its deepwater exploration operations.
Expanding Exploration in Key Offshore Basins
ONGC continues to advance exploration activities in multiple offshore regions. The company is currently undertaking significant exploration work in the Krishna-Godavari (KG) Basin along India’s east coast, one of the country’s most promising hydrocarbon provinces. At the same time, ONGC has begun ultra-deepwater drilling operations in the Andaman region, which is believed to hold substantial untapped oil and gas potential. These efforts are part of a broader strategy to explore frontier basins and diversify India’s domestic energy resources.
Exploring Global Partnerships for Complex Projects
Given the high costs and technical complexity associated with deepwater exploration, ONGC is also evaluating strategic partnerships with leading global energy companies. The company is reportedly in discussions with international oil majors including BP, ExxonMobil, TotalEnergies, and Petrobras. Such collaborations would help share financial risks, leverage advanced technologies, and accelerate exploration in challenging offshore environments.
Strengthening India’s Energy Security
Through this ambitious deepwater exploration programme, ONGC aims to boost domestic oil and gas production and reduce reliance on imports. As India’s energy demand continues to grow, expanding offshore exploration remains a key priority for both the company and the government. If successfully implemented, the programme could significantly enhance India’s hydrocarbon reserves while reinforcing the country’s long-term energy security strategy.
