The Dussafu Marin Permit

Gabon is sub-Saharan Africa’s fourth largest producer and exporter of crude oil. The Dussafu Marin Permit is a Development and Exploitation license with multiple discoveries and prospects lying within a proven oil and gas play fairway within the Southern Gabon Basin. To the north west of the block is the Etame-Ebouri Trend, a collection of fields producing from the pre-salt Gamba and Dentale sandstones, and to the north are the Lucina and M’Bya fields which produce from the syn-rift Lucina sandstones beneath the Gamba.

Dussafu is operated by BW Energy Gabon and Panoro’s current interest in the license is 17.5%. There are six oil fields within the Dussafu Permit: Moubenga, Walt Whitman, Ruche, Ruche North East, Tortue and Hibiscus. The latter four fields were discovered by Panoro and JV partners in the last 8 years, with the most recent discovery of the gross 2P 45 million barrel reserve Hibiscus field in 2019. The gross 2P reserves on the license were estimated as of end 2020 to be approximately 105 million barrels.

The first field in the Dussafu EEA area, Tortue, started oil production in September 2018 from two initial horizontal development wells drilled in the first half of 2018. In 2019/2020 a further two development wells were drilled and brought onstream, and the final two wells are planned to come online in 2021, making a total of six wells on the field. The oil from the Tortue wells is produced via subsea trees and flowlines to a leased FPSO for processing, storage and export. Production from Tortue was around 13,600 bopd gross from four wells in Q1 2021 (Net to Panoro working interest 2,380 bopd). Once all six wells are online towards the end of 2021 production is expected to reach around 20,000 bopd gross (Net to Panoro working interest 3,500 bopd).

The next phase of development at Dussafu will be the Hibiscus and Ruche fields, which are planned to be developed together and tied back to the Adolo FPSO stationed at Tortue. A FID was taken for the project in 2019, and the development will consist of 6 wells in Hibiscus and Ruche in phase 1, followed by another 6 or 7 wells, including wells in the Ruche NE field, in phase 2. The project consists of a platform, from which the development wells will be drilled, tied back to the FPSO for oil storage and export via a 20 km subsea pipeline. Phase 1 is expected to produce first oil by the end of 2022 and once phase 2 is online gross production at Dussafu is expected to be above 40,000 barrels of oil per day by 2024.

The exploration potential in Dussafu is significant with several Gamba and Dentale prospects in addition to the already discovered resources. The Hibiscus North prospect will be drilled in the 2021 drilling campaign, and in future years additional prospects may be targeted.
