Sri Lanka has officially launched the 2026 Sri Lanka Petroleum Exploration Licence Awarding Round, opening nearly 34,000 square kilometres of the Mannar Basin to international energy companies for petroleum exploration.
Under the latest licensing round, four exploration blocks in the Mannar Basin will be offered to international companies, creating an opportunity for global energy firms to assess and participate in Sri Lanka’s offshore petroleum sector.
The development comes as authorities estimate that the Mannar Basin could hold approximately two billion barrels of petroleum and nine trillion cubic feet of natural gas, based on existing geological data.
Significant Petroleum Potential in the Mannar Basin
The Mannar Basin is considered one of Sri Lanka’s key areas of petroleum potential. Previous exploration has already confirmed the presence of natural gas and liquid hydrocarbons in the basin.
However, only a relatively limited area of the Mannar Basin has been explored so far. According to the Petroleum Development Authority of Sri Lanka (PDASL), a substantial area remains to be assessed using modern geological exploration techniques and advanced technologies.
The latest exploration round therefore provides an opportunity to further investigate the basin and establish a clearer understanding of its petroleum resources.
It is important to note that the estimated figures represent potential resources based on existing geological data and do not necessarily represent commercially recoverable reserves. Further exploration, appraisal and successful extraction will be required to determine the actual scale and commercial viability of the resources.
Four Exploration Blocks Offered to International Companies
The 2026 Sri Lanka Petroleum Exploration Licence Awarding Round will offer four exploration blocks in the Mannar Basin to international companies.
Companies participating in the latest exploration round will also be given access to geological data on the Mannar Basin currently held by the Petroleum Development Authority of Sri Lanka.
The availability of this geological information can assist international companies in evaluating the exploration potential of the available blocks and making informed investment decisions.
Official Launch of the Licensing Round
The official launch ceremony was held at the Sri Lanka Petroleum Corporation Head Office Auditorium in Dematagoda.
The event was held under the patronage of Energy, Ports and Civil Aviation Minister Anura Karunathilake, Labour Minister Dr. Anil Jayantha and the Deputy Minister of Finance and Planning.
Petroleum Development Authority of Sri Lanka Chairman Prof. Dhammika Thanthrigoda, Director General Dr. Neil de Silva, Ceylon Petroleum Corporation Chairman D.J.A.S. de Rajakaruna, together with senior Ministry officials, were also present at the ceremony.
Speaking at the event, Dr. Neil de Silva said that previous exploration had confirmed the presence of natural gas and liquid hydrocarbons in the Mannar Basin, indicating significant petroleum potential.
He also highlighted that only a relatively limited area of the basin has been explored, leaving a large area yet to be assessed using modern exploration methods and advanced technologies.
An Opportunity for International Energy Investment
The opening of the Mannar Basin for international petroleum exploration represents a significant opportunity for global energy companies and investors interested in Sri Lanka’s offshore energy sector.
Sri Lanka has historically relied heavily on imported petroleum to meet its energy requirements. The discovery and eventual commercial development of domestic oil and natural gas resources could therefore have important implications for the country’s energy security and dependence on imported petroleum.
However, the potential economic impact will depend on the results of further exploration and whether any identified resources can be commercially developed and successfully extracted.
For international energy companies, the licensing round provides an opportunity to evaluate the geological potential of the Mannar Basin and consider participation in Sri Lanka’s emerging offshore petroleum sector.
Unlocking Sri Lanka’s Untapped Offshore Resources
The latest licensing round represents another step towards assessing and potentially unlocking Sri Lanka’s offshore petroleum resources.
With a significant portion of the Mannar Basin yet to be explored, the use of modern exploration technologies and access to existing geological data could help provide a more comprehensive understanding of the basin’s oil and gas potential.
For Sri Lanka, successful exploration and development could create a new dimension in the country’s energy sector. For international investors, the licensing round provides an opportunity to assess one of Sri Lanka’s most significant identified offshore petroleum prospects.
