Australia’s Comet Ridge awarded a drilling services agreement to TDC Drilling for its upcoming work programme at its Mahalo Block in central Queensland.

The Mahalo Block sits approximately 240km west of Gladstone, 14km east of a Santos-APLNG owned pipeline and approximately 40km north of both Jemena’s Queensland Gas Pipeline and the GLNG main line to Gladstone.

Comet’s upcoming work programme at the Mahalo Block involves the under-reaming of the Mira pilot wells, before commencing drilling the Humboldt South-1 corehole, which lies about six kilometres to the east-north-east of Mira, the company said in a statement.

Comet said it had agreed to a two-rig plan with TDC which it said would maximise efficiency and reduce overall costs.

Rig 8, a dedicated service rig, will be mobilised from Roma first, to undertake the Mira under-reaming work, Comet said. This involves pulling out tubing and pumps from the wells, under-reaming the coals and then rerunning tubing and pumps back into the wells so they can be put back onto production.

As that work comes to an end, Rig 10, a larger drilling rig, will be mobilised to the field from Roma to drill the new Humboldt South 1 corehole.

Comet Ridge managing director Tor McCaul said he was pleased that the programme has been able to be planned efficiently to get the best possible outcome for the lowest cost.

Comet Ridge earlier this year began work on preparing field programme for the Mahalo Block – this included well design and planning, selection of contractors and ordering of equipment, which is expected to arrive in the field to commence work before the end of July.

The company expects to be able to provide a further update to the market as Rig 8 mobilises in July.
