Jadestone Energy (Eagle) Pty Ltd (Jadestone Energy) plans to undertake monitoring of two suspended wellheads, Sea Eagle-1 and Tahbilk-1, in the Montara field via vessel-based activities. Sea Eagle-1 was drilled and subsequently suspended in 2008, and Tahbilk-1 in 1990. These wells have been accepted by the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) as being suspended.
To date annual ROV Surveillance has been used to check integrity of the wells. In the future, a remote monitoring system will be installed.
Sea Eagle-1 is within Production Licence AC/L8 and Tahbilk-1 is within production Licence AC/L7 within the Montara field which lies approximately 690 km (373 nautical miles) east of Darwin in a water depth of approximately 80 m in Commonwealth waters of the Timor Sea.
The EP validity period for the vessel-based activities, is from EP acceptance to end of 2024.
