Perenco spuds appraisal well near discovery offshore Gabon

Perenco Oil & Gas Gabon (POGG) has spudded an appraisal well in the vicinity of the Hylia South West discovery, offshore Gabon.

Hyla South West was discovered in December 2022 through exploration well HYSM-1 when a 40 m net oil-bearing column was encountered in the Ntchengue Ocean (NTO) reservoir, as well an additional column in the Madiela reservoir.

The appraisal well—targeting the NTO reservoir and the lower Madiela carbonate reservoir—is being drilled by Dixstone’s BANBA jack-up rig and is expected to last 30 days. 

The well is expected to help determine the full potential of the area and is “designed to further inform our understanding of both the NTO and Madiela reservoirs, and to narrow our estimate of oil resources in place, presently estimated at between 20 and 100+ million barrels,” said Adrien Broche, general manager of POGG.

Hylia South West field is now producing 6,000 b/d of oil from the HYSM-01 well. Production began in October 2023 (OGJ Online, Oct. 13, 2023).
