8 Jan 2008flow test result▼ BadMajor

Heron-2 testing resumed after Cyclone Helen. Only the 15m Elang sand flowed gas, about 6 MMscf/d, dry and high in CO2. Blockage and mud-loss treatment appear to have stopped the Plover flowing. MEO plans a sidetrack to redrill the Plover, then test it and the Epenarra.

4 Jan 2008flow test result● NeutralMajor

Heron-2 began flowing gas to surface from the Plover, but a prolonged clean-up is needed because lost drilling mud and loss-circulation treatment impaired the formation. The well was shut in for Cyclone Helen, and MEO called a trading halt until 8 January. No flow rates or gas quality are reported yet.

31 Dec 2007regulatory community update▲ Good

All 250 sq km of Northwest Shelf 3D seismic was acquired on time and under budget. About 40% of the 250 line km of 2D in WA-359-P is done before Cyclone Melanie halted work. The rest will be shot when the vessel is next nearby.

28 Dec 2007drilling result▲ GoodMajor

Logs show Heron-2 has drilled 202m of Plover with about 164m of gross sandstone that appears gas charged, with no CO2 recorded and 5-10% porosity. Partners approved a barefoot production test of the Plover, due the week of 31 December. The gas-water contact (4,260m) has not yet been reached.

27 Dec 2007drilling progress report▲ Good

Heron-2 weekly report no. 11: the 6in hole is at 4,182m with significant mud gas readings in the Plover. Mud losses from higher permeability were controlled. Partners will review logs, then either drill on to 4,300m or start production testing.

13 Dec 2007regulatory community update● Neutral

Seismic acquisition has begun on the Northwest Shelf permits: the Orient Explorer started 250 sq km of 3D over WA-360-P and WA-361-P, about 18 days, then 250 line km of 2D in WA-359-P. Reprocessing of the Rosie 3D over the Zeus feature is starting. Continues the 2 Nov plan.

12 Dec 2007capital raising announcement▲ GoodMajor

MEO placed 50 million shares at A$1.25 to raise A$62.5m before costs, heavily oversubscribed. Funds go to production testing, about 800 sq km of new NT/P68 3D seismic (March 2008), Northwest Shelf seismic, LNG and methanol project studies, and contingency. Earlier funds already covered dry-hole costs.

What it means for a shareholder

50.0m new shares at A$1.25 to raise about A$62.5m. That's 13% dilution: every existing holder's slice gets 13% smaller. If you held A$1,000 of shares (800 at the issue price), your slice goes from 0.000238% to 0.000207% of the company. To keep it you'd need 119 more shares - about A$149 at the issue price.

12 Dec 2007investor presentation▲ Good

December investor update. Heron-2 hit the Elang/Plover (top Elang 3,929m, about 237m high to Heron-1) with positive gas readings, then stopped at 3,983m on mud losses of up to 60 bbl/hr. It also shows downstream project NPVs (LNG US$2.5b, methanol US$950m) and the raising's use of funds.

6 Dec 2007well test result▲ GoodMajor

Partners approved a production test of the Epenarra Darwin Formation in Heron-2, citing gas saturation over 50m of Facies C (3,109-3,159m), no CO2 in mud gas and 5-12% porosity. It follows the 27 Nov logs. The test can only occur after drilling, and possible testing, of the deeper Plover.

Heron-2 weekly report no. 7: 9⅝in casing is run and cemented at 3,360m. The rig is testing the blow-out preventer for high-pressure operation and expects to start the 8½in hole over the weekend. The Elang/Plover top is prognosed around 3,900m. No new results.

27 Nov 2007drilling result▲ GoodMajor

Heron-2 logs through the Darwin Formation preliminarily indicate Facies C is gas bearing, and 18 side-wall cores were taken. Partners are reviewing the data before deciding on flow testing. MEO says it still cannot confirm gas quality or a recoverable resource until gas is recovered.

23 Nov 2007drilling progress report▲ GoodMajor

Heron-2 hit the top of the Darwin Formation at 3,062m, 62m higher than predicted, with elevated gas readings in the mud. MEO calls this encouraging but says it cannot yet confirm gas quality or a recoverable resource. Logging and testing are still needed.
