Coal seam gas explorer Comet Ridge announced Monday that the four pilot wells recently drilled at its Mira field pilot project in ATP 337P, have shown consistent coal thickness and good coal productivity, confirming the joint venture’s plans to operate two pilot schemes in the block.
Completion operations have already commenced on the Mira wells to install pumps and tubing and set the wells up for production, so that the Mira pilot scheme can be brought on line soon after the Mahalo pilot, 8 miles (13 kilometers) to the northwest of Mira.
The Mahalo pilot drilling results from 2012 and the Mira pilot drilling results recently concluded, demonstrate highly productive and continuous coals across a large area of the Mahalo block, and confirm the ingredients required for successful pilot testing and reserves booking are present in both areas of the block.
The objective of both these pilot production projects is to demonstrate commercial gas flows in ATP 337P, with the intention of achieving an early initial reserves certification.
The Mira field is approximately 155 miles (250 kilometers) west of Gladstone in central Queensland. Mira 2 is the centre well in the Mira pilot scheme and is located approximately less than one mile from each of the three recently drilled Mira pilot wells. The well reached a total depth of 1,050 feet (320 meters), intersecting approximately 30 meters (9 feet) of net coal and was cored through the reservoir section to gain additional data on coal parameters.
Mira 2 is also the fourth well in an eight-well programme for the Mahalo joint venture that commenced in mid-December 2012. Four step-out core holes will now be drilled, to further extend the area available for booking reserves in the Mahalo block. The first of these is the Scrubber Gully 2 well which is expected to spud later in the week.
Comet Ridge Managing Director, Tor McCaul said that the coals across the north of the Mahalo block have now been shown to be very productive via the eight pilot wells that have been drilled in the Mahalo and Mira fields. The four Mahalo field wells were completed for production during December, while completion operations on the Mira field pilot wells are currently underway, with that work expected to be concluded by the end of this month. Construction of production facilities has commenced at the Mahalo field and will then move to the Mira field so the Mira pilot will be operational soon after the Mahalo pilot.
He said that after much subsurface technical work over a number of years, the Joint Venture had entered an exciting new phase which is focused on producing commercial quantities of gas to enable reserves to be certified.
Comet Ridge currently has a 35 percent interest in ATP 337P Mahalo, having divested a 5 percent interest in the asset to Stanwell Corporation Limited in an agreement announced in September 2011. Under the terms of that agreement, Stanwell Corporation Limited will fund Comet Ridge's expenditure for the Mahalo field and Mira field pilot schemes. The agreement also gives Stanwell Corporation an option to purchase half or all of Comet Ridge's equity in the Mahalo block, based on 2P reserves booked.
