Perenco starts production from the Hylia South West discovery offshore Gabon

Perenco Oil & Gas Gabon (POGG) has started production from the Hylia South West discovery offshore Gabon.

The discovery was in December 2022 through the drilling of the HYSM-01 exploration well on the Mono permit in 40 m water depth 10 km south of Hylia field.  The well encountered a 40 m net oil-bearing column in the NTO reservoir. 

In addition to this primary target, the well also encountered another column, currently being tested, in the Madiela carbonate reservoir, the company said.

 In this year’s first quarter, POGG installed a 10 km pipeline and a proprietary design, self-elevating production platform to fast-track production testing through Hylia platform infrastructure, the company continued.

HYSM-01 was completed this summer and equipped with an electrical submersible pump.  It is currently producing 3,000 b/d of oil.  

POGG will begin additional testing in the coming weeks to evaluate the full potential of the discoveries in both the Madiela and NTO reservoirs, currently estimated to be 20-100+ million bbl in place. 

Additionally, studies have been launched ahead of additional appraisal and development drilling within the next 18 months.

Adrien Broche, general manager of POGG, said the discovery comes just a few months after the Wamba discovery, which is still producing 2,000 b/d of oil, and that more exploration wells are planned to be drilled offshore and onshore Gabon in the coming months, including at both Wamba and Igonguino.
