Drill Stem Tests Indicate Favorable Reservoir Quality in Block 52

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

The SAC-1 exploration well, situated approximately 8 kilometers east of the Sloanea-1 gas discovery, underwent drill stem testing. The outcomes of these tests revealed a strong gas deliverability from the encountered sandstone reservoirs. This strong performance in delivering gas is a key indicator of good reservoir quality, suggesting efficient pore space and permeability within the formation.
Oil Productivity in Roystonea-2 Appraisal Well

In parallel, the Roystonea-2 appraisal well, drilled as part of efforts to assess the reservoir's lateral reach, also underwent drill stem testing. The results from these tests were highly positive, indicating strong oil productivity. This demonstration of robust oil flow further solidifies the assessment of the reservoir system's quality and its considerable lateral extent, reinforcing its commercial viability.
Validation of Reservoir System Quality and Extent

The combined results from the drill stem tests on both the SAC-1 and Roystonea-2 wells serve to validate the overall quality and extent of the reservoir system in Block 52. The ability to deliver significant volumes of both gas and oil from these wells underscores the geological potential of the area. These findings are crucial for future development decisions and contribute to the broader prospectivity of the Suriname-Guyana basin as a deepwater hub.
