Mira 6 horizontal well production continues to steadily increase

  • Mira 6/2 horizontal-vertical well combination gas flow passes 390 000 sf3/d.
  • Strong upward gas trend continuing.
  • Latest technical data with certifier to support 2P & 3P reserves update.

Comet Ridge Limited has provided an operational update on the progress of the Mira Pilot Scheme in the Mahalo Block in central Queensland.

Since the last operational update in mid-January, the pump speed has been increased slightly while the gas rate has continued its steady climb, recently passing 390 000 sf3/d, with a strong upward trend.

Managing Director, Tor McCaul, said “all technical data has now been provided to the independent reserves certifier to generate an updated assessment of 2P and 3P reserves for the Mahalo Block as a whole, and this work is progressing on schedule to be completed during the first quarter.”

The Mira 6/2 combination and three vertical wells (Mira 3, 4 & 5) continue to actively dewater the Mira Pilot Scheme. In Mira 6/2, bottomhole pressure is being brought down gradually and still remains relatively high, indicating gas rates should continue to increase as the pressure in the pilot area is further reduced.

The downward spike in the gas rate and pump speed, corresponds to a short shut-in of the well for surface flowline maintenance work during early January.

The large upward spike in gas rate occurred soon after the well came back on-line with the well trying to unload against low back pressure. A subsequent increase in surface separator pressure, ensured gas production has developed on a more gradual trend.

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