Drill Stem Testing Confirms Favourable Reservoir Quality in Block 52

Drill stem testing (DST) conducted on exploration and appraisal wells in Suriname’s offshore Block 52 has provided strong indications of high-quality reservoirs. Specifically, the Swartzia Aspasia Complex-1 (SAC-1) exploration well demonstrated significant gas deliverability, while the Roystonea-2 appraisal well exhibited robust oil productivity. These results collectively validate the extent and quality of the reservoir system within the block.
Gas Deliverability from SAC-1 Exploration Well

The SAC-1 exploration well, located eight kilometres east of the Sloanea-1 gas discovery, underwent drill stem testing. This process revealed strong gas deliverability, a key indicator of well-connected pore spaces and permeability within the sandstone reservoirs encountered. The success of this testing suggests that the gas-bearing formations are capable of efficiently flowing hydrocarbons to the wellbore, underscoring the favourable reservoir quality.
Oil Productivity from Roystonea-2 Appraisal Well

Similarly, the Roystonea-2 appraisal well, situated seven kilometres north of Roystonea-1, also underwent drill stem testing. The results from this testing indicated strong oil productivity. This finding confirms the lateral extent of the oil-bearing reservoirs and further validates the overall quality and characteristics of the reservoir system being assessed in Block 52.
Validation of Reservoir System Extent and Quality

The combined outcomes of the drill stem tests on both the SAC-1 and Roystonea-2 wells serve to validate the quality and extent of the reservoir system within Block 52. The positive DST results for both gas and oil productivity highlight the potential of this offshore block, contributing to Petroliam Nasional Bhd's (Petronas) cumulative achievements in Suriname. These discoveries are part of a broader success that has unlocked recoverable resources exceeding one billion barrels of oil equivalent across eight successful wells.
