Eni spudded exploration well 22/19c-7 in licence P1620 (block 22/19c) targeting the HP/HT Rowallan prospect on 31 December 2018. In February 2019, Equinor acquired 8% interest from Eni. Rowallan is a large structural closure thought to hold P50 gross prospective resources of 220 MMboe. It was thought to be an analogue to the large Culzean field. The company used the âEnsco 121â for operations. On 4 April 2019 partner Serica announced that the well was drilled to a TD of 4,641 m and encountered a 182 m section of sandstones and shale but no hydrocarbons were encountered. As of 7 May 2019 it is understood the rig was still on location having carried out plug and abandonment work.   Serica was officially awarded the licence under the 25th Offshore Licensing Round back in 2010. Following a deal in 2012 with JX Nippon, the Japanese company farmed in taking an 85% interest operatorship. Then in May 2014 Eni farmed into the licence taking a 50% interest and operatorship. The licence is located near the Eastern Trough Area Project (ETAP) which involves the joint development of the Marnock, Skua, Egret, Heron, Machar, Mungo, Madoes and Mirren fields.  Interest in the licence is held by ENI UK Limited (32% + operator), JX Nippon Exploration and Production (U.K.) Limited (25%), Mitsui E&P UK Ltd (20%), Serica Energy (UK) Limited (15%) and Equinor (UK) Ltd (8%).
