25 Oct 2016drilling scheduled▲ GoodMajor

Phoenix South-2 will start within about 7 days, using the Ocean Monarch rig straight after Roc-2. It targets the Phoenix South oil field and the deeper Caley gas-condensate, to about 5,500m. Carnarvon pays the first A$5m of an expected A$20m net well cost, with a small promote offset against future production.

19 Oct 2016flow test result▲ GoodMajor

Roc-2 flowed up to 51.2 million scf/day of gas and 2,943 bbl/day of condensate (about 11,500 boe/day), limited by test equipment. Company says results exceeded expectations. It says a development well could exceed 100 MMscf/day. Resolves the Roc-2 flow test thread positively; Carnarvon holds 20%.

23 Sept 2016drilling result▲ GoodMajor

Roc-2 wireline logs confirm 60m gross gas and condensate sands, 30m net reservoir, with 100-350 mD permeability. Condensate is about 50-60 bbl per million cubic feet, similar to Roc-1. Pressure data suggests Roc-1 and Roc-2 are separate structures in some sands. Flow test expected in about three weeks.
