This Environment Plan covers inspection, maintenance and repair activities at the Patricia and Baleen Field located in Production Licence Vic/L21 and at the suspended Sole-2 well located in Production Licence Vic/L32.
The Patricia and Baleen field is located in water depths of approximately 54 m in Vic/L21, approximately 25 km off the coast from Marlo in East Gippsland, Victoria, in the eastern waters of Bass Strait.
The Patricia Baleen offshore assets consist of:
The Patricia-2 and Baleen-4 wells, which are shut-in; and
• A 24 km subsea pipeline and umbilical cable connecting the Patricia-2 and Baleen-4 wells to the Patricia Baleen Gas Plant; and
• A suspended well, Patricia-1.
The suspended Sole-2 well lies in water depths of approximately 125 m in Vic/L32 approximately 40 km south-west of Point Hicks and 50 km east southeast of the Patricia-2 well in east Gippsland, Victoria in the eastern waters of Bass Strait.
The scope of this EP covers:
• The non-operational phase of the offshore Patricia Baleen assets for a period of up to 5 years. As the pipeline and wells are shut-in, operational activities are limited to vessel operations including visual inspection, maintenance and repair activities to maintain integrity of the asset; and
• General visual inspections on the suspended Patricia-1 and Sole-2 wells to check for integrity and undertake minor repair activities such as anode replacement.
The proposed revision of the Patricia Baleen Environment Plan has been submitted by the present titleholder Santos Ltd, but has been prepared by Cooper Energy in preparation for a change in the titleholder.
