Perenco Oil & Gas Gabon (POGG), part of the UK-based Perenco Group, has announced the spudding of an appraisal well in the vicinity of the Hylia South West discovery, offshore Gabon
This field was discovered in December 2022 through the exploration well HYSM-1, when a 40 m net oil-bearing column was proved in the Ntchengue Ocean (NTO) reservoir, as well as a further column in the Madiela reservoir. The appraisal well, which is being drilled by Dixstone’s BANBA jack-up rig, is targeting the NTO reservoir and the lower, highly promising, Madiela carbonate reservoir. It is expected to last 30 days.
The Hylia South West field is now producing 6,000 barrels of oil per day from the HYSM-01 well, a significant increase since the start of production in October 2023, less than one year after the discovery.
Determining the potential
Adrien Broche, general manager of POGG, said, “The appraisal drilling is important in determining the full potential of this area after the recent exploration success at Hylia South West. It is designed to further inform our understanding of both the NTO and Madiela resevoirs, and to narrow our estimate of oil resources in place, presently estimated at between 20 and 100+ million barrels.”
Perenco Oil & Gas Gabon (POGG) has been involved in Gabon’s energy sector for more than three decades, and today produces approximately 120,000 barrels of oil equivalent per day. POGG is Gabon’s only commercial gas producer since 2006, providing natural gas to the power plants of Libreville and Port-Gentil, which are producing respectively 70% and 100% of the power for each city, and today is investing in Gabon’s future energy infrastructure. POGG is pursuing a number of projects in areas including gas to industry, LPG production, compressed natural gas, and gas to power.
