Europa Oil & Gas [LON:EOG] has received notification from the Department of Communications, Climate Action and Environment (DCCAE) that Phase 1 of Frontier Exploration Licences (FEL) 2/13 and 3/13 in the South Porcupine Basin has been extended by one year to 4 July 2017.

This will allow Europa to mature existing prospects and perform detailed mapping of all potential prospective levels on both licences, including the Pre-Rift, Syn-Rift and Tertiary plays, whilst it continues to seek a farm out partner for drilling.

Based on 2,500sq km of proprietary 3D seismic data, which was acquired in 2013, Europa has mapped gross mean un-risked Prospective Resources of approximately 1.5 billion barrels of oil equivalent (boe) in FEL 3/13 in three early Cretaceous submarine fan prospects and 595 million boe in FEL 2/13 in early Cretaceous turbidite channel prospects.

Charged by mature Late Jurassic and Early Cretaceous source rocks and contained in stratigraphic traps with elements of structural closure, these reservoirs are analogous to the Cretaceous play in the equatorial Atlantic Margin province which has delivered the Jubilee and Mahogany oil fields.
