Atlantic Margins

​​​​​​​​We are building a strategic footprint with optionality in underexplored emerging plays.

We are building a strategic footprint with optionality in underexplored emerging plays.

The Atlantic Margins and Latin America provide evidence of a working Mesozoic petroleum systems. Our focus in the region is on play diversity and multiple trapping geometries in emerging and frontier basins, which have the potential to deliver material exploration targets with line of sight to commerciality.

Currently Woodside holds exploration permits in Morocco, Ireland, Peru and Senegal.

Woodside has recently completed an acquisition of ConocoPhillips’​ interests in Senegal. Read the full announcement h​ere.


Woodside has established a material position in a highly prospective offshore region of Senegal. The SNE field offers line-of-sight to new near-term oil production and a foundation for creating a regional oil and gas hub. Significant exploration upside exists to build on this foundation.

Woodside is committed to working with our joint venture participants and the Government of Senegal to achieve the earliest commercialisation of resources in Senegal. We bring to the joint venture extensive experience in responsibly developing and operating floating production, storage and offloading (FPSO) facilities. Woodside’s expertise in horizontal well and completion design, subsea gathering system design, project execution and production excellence complements the joint venture participants’ capabilities. 

SNE is one of the largest global deep-water oil discoveries since 2014 and represents an opportunity for first oil production from 2021– 2023. The SNE field is estimated to contain contingent resources (2C) of 150 MMbbl of oil net to Woodside (~560 MMbbl, 100%). After drilling an exploration well and four successful appraisal wells, the joint venture is now executing a program of two appraisal wells. The appraisal program will provide a better understanding of reservoir connectivity by conducting interference testing.

Woodside holds three Frontier Exploration Licences (FELs 5/13, 3/14 and 5/14) and one Licensing Option (LO 16/14) in the Porcupine Basin. Woodside’s total acreage offshore Ireland is 3,907 km2

Extensive 3D seismic surveys were conducted in 2016, including 1,600 km² of 3D data in LO 16/14 and 2,400 km² of 3D data in FELs 3/14 and 5/14. 

Woodside, together with Irish and West Australian researchers, completed two dedicated whale and dolphin baseline studies in the Porcupine Basin in 2014 and 2016. The results from these two studies will be used to manage the environmental footprint of any of our activities in the Porcupine Basin.​
