Santos Limited is the titleholder and operator of the Tern field within permit WA-27-R, in the Bonaparte Basin. The Tern field is approximately 300 km west-southwest of Darwin, and approximately 100 km offshore from the Western Australian coast.
 
Within the WA-27-R permit, the Tern-2 well has been identified as plugged and temporarily abandoned since the 1980’s, with the wellhead remaining in-situ. The well is being managed in accordance with the Tern-2 Well Operations Management Plan (WOMP). As part of the ongoing management of the well, infrequent remote operated vehicle (ROV) inspections of the subsea equipment will be undertaken from contracted vessels; these surveys will be short in duration (i.e. days).
 
A survey is expected to occur at least once during the five-year period this EP is in-force. Since the actual timing of the surveys is dependent on a number of factors including vessel availability and weather conditions, this EP has accounted for activities potentially occurring in any season.
 
No new well activities are planned within the permit area, and no work on the existing well (Tern-2) is planned.
