Jadestone Energy Inc. and Jadestone Energy Eagle entered into an agreement with PTTEP Australasia (Ashmore Cartier) Pty Ltd (PTTEP AA), under which Jadestone Energy Eagle acquired the Montara Operations from PTTEP AA. Completion of the acquisition will be achieved with the acceptance of this EP by the National Offshore Petroleum Safety and Environment Authority (NOPSEMA). At the time of the submission of this EP, PTTEP AA is the sole titleholder and have operational control of the Montara Operations. As per NOPSEMA’s Guidance Note for Change to the Titleholder with operational control of activities (GN1746; Rev 1 October 2017), this EP was prepared by Jadestone Energy Eagle and submitted by PTTEP AA on behalf of Jadestone Energy Eagle. Coinciding with the acceptance of this Environment Plan, Jadestone Energy Eagle will become the sole Titleholder, having operational control of the Montara Operations.
The Montara Venture Floating Production Storage Offtake (FPSO), unmanned wellhead platform and subsea infrastructure, are located in the Timor Sea, in the Ashmore Cartier territory within Commonwealth waters, approximately 690 km north-west of Darwin within 34 km of Vulcan Shoal. The facilities lie in water depths of approximately 80 m.
The Montara operations currently produce crude oil from the Montara, Skua, Swift and Swallow fields which is transported via flowline for processing at the well head platform and FPSO. The well head platform currently has five production wells, and there are five subsea production wells located approximately 17 to 18 km from the FPSO.
The Montara infrastructure is marked on nautical maps surrounded by a 500 m petroleum safety exclusion zone within which vessels are prohibited from entering.
The revised EP provides for operation of the FPSO and well head platform, and associated subsea infrastructure, situated in licenses AC/L7 and AC/L8. In addition, the revised EP provides for inspection, maintenance and repair of infrastructure, support services, and unplanned activities including oil spill response.
