Activity Description

Santos Northwest Pty Ltd (Santos) proposes to drill the Corvus-2 appraisal well, located in Commonwealth waters of approximately 65 m depth off the coast of Western Australia (WA).
The drilling campaign (the activity) will be carried out using a jack-up mobile offshore drilling unit (MODU). This environment plan (EP) covers all MODU, support vessel and helicopter operations within the operational area
All petroleum activities will be conducted in Permit Area WA-45-R. The operational area is set as a 500 m radius around the final well location, corresponding to the gazetted safety exclusion zone around the MODU. The Corvus-2 appraisal well is proposed to be drilled, evaluated and permanently plugged and abandoned.
Drilling activities are planned for approximately 42 days, but the environmental assessment and stakeholder consultation accounts for over-run (~80 days). Activities will be conducted 24-hours per day, seven days per week. Over-runs may be caused by unfavourable weather, additional drilling (e.g. a re-spud) or operational challenges.
The earliest date for MODU arrival is 1st March 2019. To account for potential delays or schedule changes, the environmental assessment encompasses petroleum activities at any time of the year. Thus the activity will be undertaken between 1st March 2019 and 31st December 2019.
