MANNAR BASIN OFFERS SIGNIFICANT OFFSHORE EXPLORATION POTENTIAL

The Mannar Basin presents a compelling offshore exploration opportunity, combining a proven petroleum system, significant remaining exploration potential and strong commercial fundamentals.

SL2026-01 offers four offshore exploration blocks covering almost 34,000km², giving international explorers access to a comparatively underexplored basin with confirmed gas discoveries and a clear domestic gas market.

Why Sri Lanka?

🇱🇰 Proven petroleum system – Exploration has confirmed mature source rocks, effective migration, quality reservoirs, regional seals and working traps.

🇱🇰 Significant remaining upside – Large areas remain lightly explored, with modern seismic identifying multiple undrilled structures and stratigraphic opportunities.

🇱🇰 Strong domestic market – Growing demand from Sri Lanka’s power and industrial sectors provides a clear domestic market for natural gas.

🇱🇰 Stable and transparent framework – A strengthened regulatory environment, contractual certainty and a transparent licensing process provide a clear pathway for investors.

🇱🇰 Strategic location – Sri Lanka’s position in the Indian Ocean offers access to regional markets and significant long-term investment potential.
