09 Nov 2020: Pilot Energy are to sell a 78.75% interest in and transfer operatorship of offshore Perth Basin exploration permit WA-481-P to Triangle Energy, an oil producer. This follows announcement in October that Pilot would acquire Key Petroleum's 40% stake in WA-481-P to become sole owners. Pending completion of this acquisition and after the sale to Triangle, Pilot will retain a 21.25% non-operated working interest in the WA-481-P permit area. Triangle will pay Pilot $300,000 in cash and fund Pilot through completion of the WA-481-P Permit 3 Year work program (up to a maximum of $1.22 million). Pilot will be designated the operator’s representative in connection with all matters relating to the interface with any potential offshore wind development affecting the WA-481-P permit area. Triangle and Pilot have also agreed to form the Cliff Head Wind and Solar Project Joint Venture (Wind & Solar JV) with Pilot owning 80% and Triangle 20%. The Wind & Solar JV will assess the feasibility of the development of an offshore wind and onshore wind and solar power project centred around the Cliff Head Offshore Oil Field production facilities, Cliff Head Alpha and the onshore Arrowsmith Separation and Processing Facilities. WA-481-P is located immediately adjacent to, contiguous with and surrounds the offshore Cliff Head Oil Field. The field is located in the Perth Basin about 270 kilometres north of Perth and 12 kilometres off the coast of Dongara in Western Australia. Triangle is majority owner and operator of the Cliff Head Offshore Oil Field and the onshore Arrowsmith Separation and Processing Facilities. In September 2020 Pilot entered into an agreement to acquire Royal Energy Pty Ltd, which holds an effective 21.25% interest in the Cliff Head Oil Field. Triangle has agreed that Pilot’s share in any oil and gas discoveries in WA-481-P will be developed and produced through the Cliff Head Oil Field facilities and that Pilot will have access to these facilities on the same basis as Triangle. Through the shared ownership of WA-481-P and Cliff Head Oil Field synergies can be achieved. Many of the required feasibility studies for and offshore wind project can use historical data collected for oil and gas exploration and vice versa. For example historical wind speed measurements were taken from the Alpha Platform and further resource measurements could also be taken at a low cost by Pilot from the Platform. The JV will undertake detailed assessment of the feasibility and pursue the development of an offshore wind farm and onshore solar project whilst integrating with the existing Cliff Head Oil Field offshore and onshore facilities and operations to allow for cost savings. The Cliff Head Alpha Platform will become multitasking as it will also act as an offshore substation. The conceptual layout for the four stage 1.1 GW development includes up to 78 turbines, each with a 14 MW capacity. The offshore wind turbines will be located at least 14 km offshore and in water depths of between 20-40 metres. The cut-off date for the WA-481-P transaction to complete is 15 March 2021.
