NOPSEMA approves BP Ironbark drilling plan

BP has been given the green light by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) to drill the Ironbark-1 exploration well in the Carnarvon Basin offshore Western Australia.

The regulator has approved BP’s environment plan (EP), which includes exploration drilling and associated activities to be undertaken by the company with a mobile offshore drilling unit (MODU).

The EP was submitted to NOPSEMA in December 2019 and was accepted last Thursday.

Ironbark-1 is in permit WA-359-P in Commonwealth waters, 170km offshore Karratha. It is a joint venture between BP (42.5 per cent, operator), Cue Energy (21.5 per cent), Beach Energy (21 per cent) and New Zealand Oil and Gas (15 per cent).

BP plans to begin drilling activities in the third quarter of 2020, depending on MODU availability. The drilling is expected to take 90-100 days, with activities to be conducted on a 24-hour basis.

Outlined in the EP, the Ironbark prospect is targeting multiple objectives within the Triassic Mungaroo Formation, which has been explored at comparably shallower depths and includes the Gorgon, Julimar – Brunello, Iago, Goodwyn, Perseus and North Rankin gasfields.

The Ironbark-1 well is expected to drill to approximately 5500 metres and will be the first test of the Ironbark gas prospect.
