Petroliam Nasional Bhd (PETRONAS), via its wholly-owned unit PETRONAS Energy Guyana Sdn Bhd (PEGSB), has signed a Petroleum Agreement (PA) for Block S4 in the shallow offshore waters of Guyana.
The agreement was executed with the government of the Cooperative Republic of Guyana and consortium partners TotalEnergies EP Guyana Shallow SAS (TotalEnergies) and QatarEnergy, marking PETRONAS’ first entry into Guyana and expanding its presence in the Americas.

The PA follows the consortium’s successful bid in the 2022 Guyana Licensing Round and represents a key milestone in PETRONAS’ expansion in the Guyana-Suriname Basin, a region recognised as a promising frontier for oil exploration.
Block S4 spans roughly 1,787 sq km and is strategically situated along favourable hydrocarbon migration pathways. Under the agreement, PETRONAS holds a 25% stake, QatarEnergy 35%, and TotalEnergies 40%, with TotalEnergies acting as the operator.
The signing ceremony in Georgetown was attended by PETRONAS’ Harris Saifi B Hakimi, Guyana Petroleum Minister Vickram Bharrat, TotalEnergies’ Daniel Larranaga, and QatarEnergy’s Ali Al-Mana.
PETRONAS vice-president of exploration Faisal Bakar said, “Our entry into the Guyana-Suriname Basin marks a significant step in PETRONAS’ international growth. Through a disciplined expansion strategy, we aim to unlock the basin’s proven potential and deliver lasting value to our stakeholders. Our partnership with TotalEnergies and QatarEnergy strengthens our commitment to a resilient and progressive upstream sector.”
The inclusion of Block S4 reinforces PETRONAS’ footprint in the Americas and its position as a competitive global energy player.
