Hitherto not reported and according to industry sources, Eni Gabon SA (Eni) has found gas in the outpost Nyonie Deep 1ST1. Although not tested, the well has confirmed the Nyonie Deep gas discovery made in block D4 in northern Gabon in 2014. The well was spudded on 14 June 2019 and suspended on 3 September 2019 when the âTopaz Drillerâ J/U left the area.    Earlier in early June 2019, AndrÃ© Marsanich, the former general manager of Eniâs Gabon, announced in a meeting with former Oil Minister Pascal Houangni Ambouroue, the imminent start of an appraisal well on Nyonie Deep field The gas and condensate accumulation is located in the northern part of Gabon in both blocks D3 and D4 within the North Gabon Sub-basin (Gabon Coastal Basin). Eni booked a slot with the âTopaz Drillerâ J/U owned by Vantage Drilling International just after its use by Total in Torpille Marine field. In early 2019, Eni has conducted studies related to the future appraisal location at the Nyonie Deep field.    Eni is the operator and sole participant in both blocks D3 and D4.  Background Information    In late October 2015, Eni completed its operations in the outpost Nyonie Deep 2 located within block D4. The well encountered gas and was spudded on 14 April 2015.  On 31 July 2014, Eni announced that it had discovered gas and condensate with the Nyonie Deep 1 exploration well, located within block D4. The well was spudded on 10 April 2014, at a water depth of 28 m with the âWest Mischiefâ J/U. It targeted the Pre-Salt Nyonie Deep prospect and was drilled to a TD of 4,314 m. Eni estimated the discovery to hold a potential in-place resource of 500 MMboe. The well intercepted a 320 m hydrocarbon bearing section in a Pre-Salt Aptian aged clastic sequence. The structure covers more than 40 sq km and extends into block D3. The well had a planned TD of 4,250 m with objectives in the Gamba and Coniquet formations.
