Petronas subsidiary Petronas Suriname E&P BV discovered oil at the Roystonea-1 exploration well in Suriname’s Block 52. The company is working to evaluate the full extent of the discovery and its potential development synergy with the Sloanea-1 discovery made in 2020 within the same block, the company said in a release Nov. 2.
The well, which lies about 185 km offshore in water depth of 904 m, was drilled to a total depth of 5,315 m. The well encountered several oil-bearing Campanian sandstone reservoir packages.
The 4,749-sq km block lies north of the coast of Paramaribo, Suriname, within the prospective Suriname-Guyana basin in water depths from 50-1,100 m.
Petronas is operator of the block with 50% interest. ExxonMobil holds the other 50% (OGJ Online, May 19, 2020).
In addition to Block 52, Petronas operates Block 48 with 100% interest. It is also a non-operating partner (30%) in the adjacent Block 53 where the Baja-1 oil discovery was made in 2022.
