Mira begins production

Comet Ridge’s Mira Pilot Scheme in ATP 1191 in the Mahalo Block in central Queensland has begun producing gas for Australia Pacific LNG (APLNG).

The Mira-6/2 horizontal-vertical well combination was brought online by APLNG in December last year and commenced producing gas after two days.

This combination and the other three vertical wells (Mira-3, -4 and -5) have been online over the past month and are actively dewatering the Mira Pilot Scheme.

Measured gas rates have been increasing steadily and last week passed 200,000 cf/d for the Mira-6/2 combination on a rising trend.

Bottomhole pressure remains relatively high, indicating additional flow potential as gas rates are expected to increase significantly as the pressure in the pilot area is reduced.

Comet Ridge Managing Director Tor McCaul said he was very pleased with the results over the last few weeks.

“The gas rate increase in Mira-6/2 has been much more rapid than for the horizontal well at the Mahalo pilot, and this is consistent with having a longer horizontal well at Mira contacting much more coal,” said Mr McCaul.

The Mahalo Project is located approximately 240 km west of Gladstone in the southern Bowen Basin.

It is close to infrastructure with pipeline connections to the Gladstone domestic and LNG market a short distance to both the west and south of the two pilot schemes.

Equity participants in ATP 1191 Mahalo CSG are Comet Ridge (40 per cent and operator), APLNG (30 per cent) and Santos (30 per cent).
