Comet Ridge brings online Mira 6 well in the Mahalo Block
Monday, Dec 11, 2017
  • Mira 2 pump successfully started on 10th December 2017
  • Mira 6 provides a 920m long drainage point through centre of the pilot for water & gas
  • Two under-reamed vertical wells are producing gas

Comet Ridge Limited is pleased to provide an update on production operations at the Mira pilot scheme in the Mahalo Block in central Queensland.

The recently drilled Mira 6 horizontal well, which ran inside the Castor coal seam for approximately 920m and intersected the Mira 2 well at about the mid-point, has come on-line and is producing water as planned. Figure 1 shows a plan view of the Mira 6 well path down through the centre of the triangular Mira pilot scheme, intersecting the centre well, Mira 2. Gas and water will flow along the horizontal Mira 6 well (from both ends, towards the centre) and then up through the Mira 2 vertical well to surface (refer Figure 2). Mira 6 and Mira 2 will operate in combination – the horizontal well collecting water and gas from fractures in the coal seam and the vertical well lifting that water and gas to surface.

Comet Ridge Managing Director, Tor McCaul said unseasonably high rainfall had continued from October into December and had subsequently delayed the connection of the Mira 2 well and the start up of the pump by two weeks. He said now that the well was online, he was looking forward to seeing water and gas rates climbing steadily as the pump speed increased over the coming weeks.

Mr McCaul also noted that two of the three under-reamed vertical wells were now producing gas as they also de-water the pilot area. He said Mira 5 had been producing gas soon after being back on-line in August and Mira 3 started producing gas two weeks ago with gas rates steadily improving.

The Mahalo project is located approximately 240km west of Gladstone in the southern Bowen Basin. The Project is located 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 Coal Seam Gas are Comet Ridge Mahalo Pty Ltd (40%), Australia Pacific LNG Pty Ltd (30%) and Santos QNT Pty Ltd (30%).
