Zennor Petroleum is offering an opportunity for interested parties to farm-in to licence P2310 (2/5b) containing the Middle Jurassic Brent SW Heather discovery. Zennor is looking for parties to fund the development of SW Heather. The development concept involves a 35 km subsea tieback to the Ninian Central platform. An alternative development option could involve using a standalone FPSO.Â  Zennor has derived a best technical reserve estimate of 31 MMboe. P2310 was awarded in May 2017 during the 29th Licensing Round. In Q3 2017 Zennor reprocessed its 3D seismic data to develop a new structural interpretation of the discovery. Zennor is currently undertaking reservoir modelling while also integrating well data from analogue fields in the area. As of January 2019, the opportunity was still available.  SW Heather is interpreted as a faulted anticline located 8 km south of the Broom field and discovered from Unionâs three well drilling campaign to define the trap. Discovery well 2/5-10 drilled in 1979 tested a cumulative 6,000 bopd from the Emerald, Brent and Triassic sands. The shallow marine transgressive Emerald and Brent sands comprised of a 144 ft package with reservoir parameters of 60% N/G, 18% porosity and 40% Sw. Based on RFT data the sands are in pressure communication. The recovered oil from the Brent was 33.8-34.8Â° API and a 330-350 m GOR was derived. The underlying Triassic Cormorant Formation is also oil bearing and flowed on test after acidisation. The interval consisted of a 78 ft net reservoir, 16% porosity and 48% Sw. Â   Well 2/5-11 was drilled down-dip in 1979 but encountered water bearing Brent. Well 2/5-16ST drilled in 1983 and targeted reservoirs up-dip but was interpreted as dry. However, Zennor believe the well was drilled heavily overbalanced from poor hole conditions encountering several drilling problems. More recent geochemical analysis indicates the presence of oil in the well cuttings which were previously interpreted poorly. Â   Zennor North Sea Limited holds 100% interest in P2310. A data room will be available in Zennorâs Guildford offices in Q2 2018.
