Icon Energy: Geoffrey-1 Well Reaches Total Depth
Icon Energy Limited said that the Geoffrey-1 well in ATP 855 reached total depth of 4,125 metres in the Patchawarra Formation on 9 December 2013.
Geoffrey-1, a vertical exploration well 36 kilometres to the north-east of Hervey-1, was drilled to evaluate the shale and basin-centred gas play in the Toolachee, Daralingie, Roseneath, Epsilon, Murteree and Patchawarra Formation intervals in the east of the permit within the Queensland portion of the Nappamerri Trough.
The results of the well have been very encouraging with good gas shows throughout the entire Permian section. The well is currently running wireline logs and will be cased and suspended pending subsequent hydraulic stimulation and flow testing as part of a multi-well stimulation campaign beginning in the first quarter of 2014.
The fifth well in the ATP 855 drilling program will be Redland-1, located 22 kilometres northwest of Geoffrey-1 in the north of the permit. The well, which is planned to be drilled to a total depth of 3,800 metres, will be spudded in the coming days and will specifically target the Permian Toolachee and Daralingie Formations.
Subject to joint venture approval, a sixth well will be drilled in the current exploration program and is planned to be completed within the first half of 2014.
The work program through 2014 will include hydraulic stimulation and extended well testing. This will involve optimisation of the hydraulic stimulation program which will focus on specific horizons in each well across the permit.
All wells drilled within ATP 855 to date, Halifax-1, Hervey-1, Keppel-1 and Geoffrey-1, have confirmed the continuation of a basin-centred gas play in the Nappamerri Trough in Queensland. Notices of Petroleum Discovery have already been lodged with the Department of Natural Resources and Mines (DNRM) for Halifax-1 and Keppel-1.
