PETRONAS Makes Latest Oil and Gas Discovery in Suriname's Offshore Block 52

KUALA LUMPUR, 16 May 2024 –PETRONAS Suriname E&P B.V. (PETRONAS Suriname E&P), a subsidiary of PETRONAS, has made a third hydrocarbon discovery in Block 52 at the Fusaea-1 exploration well in Suriname’s Block 52, located about 170 kilometres offshore and 9 kilometers east from Roystonea-1

The well was spudded in Feb 2024 and successfully drilled to a total depth of 5,227 metres with zero (0) LTI, encountering several oil and gas-bearing Campanian sandstone reservoir packages. Further evaluation is being undertaken to determine the full extent of this discovery and its potential for an integrated development with the recent Roystonea-1 and Sloanea-1 discoveries.

PETRONAS' Executive Vice President and Chief Executive Officer of Upstream, Datuk Adif Zulkifli stated, "The favorable results attained from the Fusaea-1 exploration well have solidified PETRONAS' standing in Suriname for material hydrocarbon resource, following the Sloanea-1 and Roystonea-1 discoveries."

PETRONAS Vice President of Exploration, Mohd Redhani Abdul Rahman said, “The success of Fusaea-1 is a testament to the advancements in our geological comprehension of this region, bolstered by recent breakthrough in Roystonea-1 and Sloanea-1. These discoveries have significantly expanded the prospectivity and integrated oil and gas development potential within Block 52. In pursuit of sustainable and high-value material resource, PETRONAS remains committed in its exploration activities in selected focus regions as part of its portfolio rationalisation efforts.”

Block 52, which covers an area of 4,749 square kilometres, is located north of the coast of Paramaribo, Suriname’s capital city, within the prospective Suriname-Guyana basin. PETRONAS Suriname E&P is the operator of Block 52 with a 50% participating interest together with ExxonMobil.

In addition to Block 52, PETRONAS Suriname E&P operates Block 48 and Block 63 with 100% participating interest and 30% non-operating interest in Block 64.

Staatsolie approves Commercial Field for Sloanea-1 Gas Discovery in Block 52

13 Nov 2025



Staatsolie Maatschappij Suriname N.V. (Staatsolie) is pleased to announce its approval on 11 November 2025 of the Commercial Field for the Sloanea-1 gas discovery, located in Block 52 offshore Suriname. This achievement represents a significant step forward in developing Suriname’s offshore petroleum resources and underscores the continued collaboration between Staatsolie and PETRONAS Suriname Exploration & Production B.V. (PETRONAS Suriname).

Staatsolie and PETRONAS Suriname signed the Production Sharing Contract (PSC) for Block 52 in 2013. Since then, three discoveries have been made in this block. PETRONAS Suriname is the operator of Block 52, holding an 80% participating interest while the remaining 20% participating interest is held by Paradise Oil Company (POC), a Staatsolie subsidiary. In late 2020, the Sloanea-1 exploration well was drilled, which encountered a gas-bearing reservoir.

In accordance with the PSC, Staatsolie and PETRONAS Suriname evaluated monetization options for this gas discovery, resulting in a gas addendum to the PSC. In 2024, PETRONAS Suriname advanced the appraisal of the Sloanea reservoir by drilling the Sloanea-2 appraisal well to assess its lateral extent and conduct comprehensive well testing. This confirmed the field’s gas-in-place and recoverable volumes. On 11 November 2025, Staatsolie approved the delineation of the Commercial Field for the Sloanea-1 gas discovery, signifying its ‘declaration of commerciality’. The selected development concept includes gas development wells, subsea infrastructure, and a floating LNG facility, a first in the region.

PETRONAS Suriname will now proceed with drafting and submitting the Development Plan for Staatsolie’s approval. Following this, parties will declare their Final Investment Decision (FID) for this gas field. With FID planned in the second half of 2026, Suriname may expect first gas to flow in 2030. Another major milestone, aligned with Staatsolie’s vision of Energizing a Bright Future for Suriname.
