Supernova Energy operate (90%) Block 7B offshore Guinea Bissau. This large exploration block has a number of viable prospective plays and is currently being evaluated by Supernova. The block has a large 2D database covering most of the acreage and Polarcus acquired a 3D survey over the deeper half of the block in 2013. In 2014 Supernova commissioned an interpretation of the 3D and the integration of the survey results with 2D, Basin Modelling and other regional studies.

In 2017 Supernova commissioned Beagle Geoscience, a UK technical firm with excellent credentials in the MSGBC region, to carry out a full study over both the block and the deepwater basin area. This new prospectivity study has integrated data and petroleum systems elements over the entire deepwater Guinea Bissau basin, resulting in a more comprehensive and coherent evaluation. The new Prospect Inventory benefits from the holistic approach to the basin as well as the block. The proprietary report forms the basis of an upgraded Data Room running in London. Supernova and Petroguin have also been awarded a two year extension to Stage 2 of the JVA and intend to carry out a more detailed study over an augmented 3D database over the next two years.

Across the Atlantic in Latin America oil companies are successfully drilling in Surinam and Guyana, in geological basins thought to be previously conjugate with the Guinea Plateau.

The acreage has at least three highly prospective play fairways. In the shallow part of the block the Cretaceous clastics overly U Cretaceous source rocks (Turonian), similar to the proven play further north at Sinapa. Below this play lies the Lower Cretaceous section, a substantial section with multiple opportunities for reservoir and source pairings. Structural leads are found over most of the block and continue off the shelf into the deepwater part of the block. Here play fairways are expected through from the Jurassic (carbonate source and reservoir) through to the Lower Cretaceous deep marine clastics of the distal Casamance system. Reefal carbonates are also seen to develop on the crest of the carbonate platform in the block.

The recent Beagle Geoscience study has mapped major structural leads closing against the Jurassic platform margin, and large sand-rich deep marine channel and turbidite systems occurring deep into the western half of the block.

Supernova Energy offers the opportunity to suitable Joint Venture partners to farm-in to the prospective offshore exploration Block 7B in Guinea Bissau. The Block 7B (8,736 km2) lies within an area of active exploration in West Africa, with major hydrocarbon discoveries in Senegal and Mauritania to the north, and super-majors taking acreage in AGC, Senegal and Mauritania and in Guinea Conakry to the south.

Project summary
