Equinor submitted the environment plan for the drilling of the Stromlo-1 exploration located in the Great Australian Bight in April 2019. NOPSEMA wasn’t able to make a decision within 30 days so, in late June, it requested further information from Equinor.

Equinor then in August requested more time and NOPSEMA resumed the assessment process in September.

Come early November and NOPSEMA issued a notice to Equinor “requiring them to modify and resubmit their environment plan for proposed drilling in the Great Australian Bight.” Equinor was given 21 days to provide NOPSEMA with further information about matters relating to consultation, source control, oil spill risk and matters protected under Part 3 of the Environment Protection and Biodiversity Conservation Act 1999.

On November 29, 2019, Equinor re-submitted its environment plan for proposed drilling activity in the Great Australian Bight, following an opportunity to modify and resubmit as a standard component of the assessment process.

In accordance with the Environment Regulations, NOPSEMA has resumed its assessment of Equinor’s environment plan, the regulator said on Monday, December 2.

The next decision point in the assessment process is scheduled to occur by December 30, 2019. Prior to this point, NOPSEMA will continue to assess the environment plan and consider potential environmental impacts from the proposed activity to ensure appropriate precautions are taken.

NOPSEMA noted it could extend the timeframe of the assessment if additional time is required.

Equinor’s planned well is located in the Ceduna sub-basin, off southern Australia. The well is located approximately 400 km southwest of Ceduna and 476 km west of Port Lincoln and in a water depth of approximately 2240 meters.

According to Equinor’s plan, the petroleum activity will occur anytime between October and May during the three years validity period from 2020 to 2022. No drilling will take place between June to September inclusive.

The duration of the drilling of the Stromlo-1 well is expected to be approximately 60 days, with the drilling planned to begin in late 2020.

In related news, Australia-based Karoon Gas has recently decided to ditch its exploration permit located in the Great Australian Bight area thus joining oil majors Chevron and BP who had previously abandoned their Bight permits.
