Field Development Plan Flexibility for future expansion Liquids focused - gas enabled • ‘Hub and Spoke’ wells – facilities system. ‒ Unmanned offshore platforms, processing onshore. • Oil, condensate and wet gas to onshore hub. • Liquids stripping and NGL extraction at hub. • Supply dry gas to fertiliser plant. • Liquids marketable internationally. • Full field development concept – LNG schemes. Stage I - Key Statistics • Sufficient P90 gas volumes to support fertiliser plant. • Dry gas to fertiliser plant: 70mmscfd. • Initial liquids production: ~ 14k-16k boepd* (inc LPGs). • First production integrated with fertiliser timetable. • Initially IM (Intra Isongo). • Gross development capex † : ‒ Pre first production: estimated $650 million - $700 million (EEAA case). ‒ To be further refined during FEED. * Operator projections. † Operator estimates.
