BG Group has made a natural gas discovery in the Ngisi-1 well in Block 4 off Tanzania. The well, drilled by the Deepsea Metro 1 drillship, appraised the Chewa gas field resulting in an upgrade in estimated recoverable resources in the block. Recoverable resources across the Chewa-Pweza- Ngisi hub are now estimated at 4.5Tcf, up from 3.7Tcf. BG is operator of Block 4 with 60%, while partner Ophir Energy holds 40%.
Nick Cooper, CEO of Ophir, said: “The successful Ngisi drilling results provide critical mass for the aggregation and development of the gas discoveries in Block 4. These (reserves) will be piped ashore and combined with the Block 1 resources for Tanzania’s LNG development.”
