Drill Stem Tests Indicate Favourable Reservoir Quality for Hydrocarbon Production

Drill stem tests (DSTs) conducted on exploration and appraisal wells in Suriname's offshore Block 52 have provided strong indications of excellent reservoir quality, demonstrating significant potential for both gas and oil extraction. The Swartzia Aspasia Complex-1 (SAC-1) exploration well, in particular, yielded DST results that pointed to substantial gas deliverability, a key indicator of a high-quality reservoir system.
Gas Deliverability from Swartzia Aspasia Complex-1

The SAC-1 exploration well, situated approximately 8 kilometres east of the Sloanea-1 gas discovery, underwent drill stem testing. These tests confirmed strong gas deliverability, a crucial metric in the oil and gas industry that signifies the ease with which hydrocarbons can flow from the reservoir rock into the wellbore. This strong performance suggests that the sandstone reservoirs encountered in the SAC-1 well possess favourable pore and throat characteristics, allowing for efficient gas migration and production.
Oil Productivity in Roystonea-2 Appraisal Well

Further supporting the positive assessment of the reservoir system's quality and extent were the results from the Roystonea-2 appraisal well. This well, drilled 7 kilometres north of the Roystonea-1 discovery, confirmed the lateral continuity of oil-bearing reservoirs. The drill stem testing performed at Roystonea-2 indicated strong oil productivity, reinforcing the findings from SAC-1 and underscoring the overall robust nature of the hydrocarbon-bearing formations within Block 52. These results collectively validate the potential of the reservoir system to yield significant recoverable resources.
