Sager #1 is a dry hole: logs show the zones of interest wet, and the gas-show zone appears depleted. The well will be temporarily plugged and abandoned. Grand Gulf bears about 57.15% of the plugging costs. It is the first setback in the post-blowout drilling program.

1 Oct 2010annual report● Neutral

Annual report for the year to 30 June 2010. The Chairman calls it a positive year of rebuilding, marred by the D&L #1 blowout, with most costs expected to be insured. He says neither Grand Gulf nor its Texas subsidiary has been named in a lawsuit, and investors have kept lending while the entitlement issue is delayed.

Sager #1 is at 9,585 ft with significant gas shows, but their meaning awaits logging at the 10,100 ft target depth. On D&L #1, 800 ft of casing has been recovered and the well may still become a producer.

Dugas & Leblanc #2, the relief well, reached total depth with over 118 ft of net oil and gas pay across three Big Hum sands. Completion takes about 2 weeks, then testing, with initial rates of 200+ barrels a day hoped for. The company believes the 1.2 MMBO and 3 BCF target is not materially reduced by the blowout.

Grand Gulf secures a A$3m loan from Seaspin (linked to Chairman Charles Morgan) and Skye Equity at 8% to fund working capital during the entitlement offer.

25 Aug 2010drilling progress report▲ Good

Dugas & Leblanc #1 "bridged off" on 23 August, when sand built up and plugged the wellbore, so the well is currently dead. A new wellhead stack is still to be fitted within two days and risk remains. The relief well, Dugas & Leblanc #2, is drilling below 2,000 ft.

Grand Gulf sets out cost scenarios for the Dugas & Leblanc #1 blowout: its share could be about US$1.92m if the relief well is needed. A class action has been filed against the operator. A supplementary prospectus will be needed. Underwriters retain a material adverse change right, and loan funds will likely be needed.
