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 7.5%. 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 7 years, with the most recent discovery of the gross 2P 45 million barrel reserve Hibiscus field in 2019. The current gross 2P reserves on the license are estimated at 112.4 million barrels.
The development of the Dussafu fields is ongoing, with oil production from 2 wells at the Tortue field having started in September 2018. Oil is produced from the Gamba and Dentale reservoirs at Tortue into a leased Floating, Production, Storage and Offloading (FPSO) vessel via subsea trees and flowlines. Phase 2 development activities at the Tortue field, consisting of an additional four production wells, are underway. All six wells are expected to be online at Tortue in 2020 with gross production is expected to average 19,500 bopd for the full year with the second half of 2020 anticipated to average at 23,000 bopd.
After Tortue, the third phase of the project will consist of the tie-back of the Hibiscus and Ruche fields to the FPSO via a wellhead platform and subsea pipeline and JV partner approval of the project is expected shortly. Once Hibiscus and Ruche are online gross production at Dussafu is expected to be above 40,000 barrels of oil per day.
The exploration potential in Dussafu is significant and interpretation of recent 3D seismic data has confirmed several Gamba and Dentale prospects in addition to the already discovered resources. Certain of these prospects will be targeted in the planned 2020 drilling campaign.
