Activity Description
Jadestone Energy (Eagle) Pty Ltd (Jadestone Energy) plans to undertake monitoring of two temporarily abandoned 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.

To date annual ROV Surveillance has been used to check integrity of the wells. In the future, a remote monitoring system will also 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 5 years from EP acceptance.
