Diamond rig set to leave Ironbark well location
Ocean Apex, a Diamond Offshore-owned drilling rig, is working on plug and abandonment activities at the Ironbark-1 well for BP with plans to demobilise underway.
The BP-operated Ironbark-1 well is located in WA-359-P in the North Carnarvon Basin offshore Australia.
The well was drilled to a total depth of 5618m by 29 December 2020. The primary target interval was intersected at a depth of 5275 metres, with no significant hydrocarbon shows encountered in any of the target sands.
It was a world scale prospect in a highly prospective address but the results were disappointing.
In an update on Friday, New Zealand Oil & Gas (NZOG), one of BP’s partners, informed that plug and abandonment operations continue as planned at the Ironbark-1 well location.
Preparations to demobilise the rig are underway and this is expected to occur during the coming week, NZOG added.
NZOG said it will issue a final update for the Ironbark-1 operations following confirmation that the rig has left the location.
Participants in WA-359-P are BP (operator, 42.5 per cent), Cue Exploration (21.5 per cent), Beach Energy (21 per cent) and NZOG (15 per cent).
The exploration permit WA-359-P is located some 50 kilometres from existing North West Shelf LNG infrastructure. The Ironbark well was drilled in a water depth of around 300 meters.
