Overview
- On Tuesday, June 9, 2026, SAGE said it had finished technical and financial feasibility work and seabed surveys and the Petroleum Ministry asked GAIL, Engineers India Ltd and Indian Oil to prepare a detailed feasibility report.
- The proposed route would run about 2,000 kilometres across the Arabian Sea with sections deeper than 3,000 metres which would require specialised deepwater engineering and make repairs costly and difficult.
- Project documents put capital costs at roughly Rs 40,000 crore and project proponents estimate transport costs of about $2–2.25 per MMBtu, though those figures are preliminary and sensitive to overruns and future gas prices.
- Major obstacles remain including who will finance the large upfront investment, whether long‑term supply contracts can guarantee returns, and how operators would manage leak detection and repairs at extreme depth.
- The plan revives a three‑decade‑old idea that could strengthen Gulf–India energy ties and later carry alternative fuels, but its fate depends on the coming detailed feasibility work and commercial commitments.
