3 June 2019

Extended reach well deviated SSE from Jade Field template to Romeo North; Triassic down-thrown fault block separated from Jade Central Horst by small, potentially sealing fault. Joanne Sandstone main objective. Main hole encountered full gas column in Joanne from 18,477 ft (16,430 ft TVDSS), but with pressure depletion. Losses taken and BHA stuck at 18,477 ft (16,430 ft TVDSS). Sidetrack drilled Joanne successfully, also with full gas column to TD at 19,745 ft (17,688 ft TVDSS), with net/gross 0.284, porosity 12.6% and Sw 21.7%. Final offset c. 6,200 ft. Well completed; tested initial 40 mmscfgpd + 6,300 bcpd, but declining.
