Stag
Jadestone acquired a 100% operated interest in Stag, a developed oil producing field, in November 2016. Stag is located within the boundaries of the WA-15-L production licence in the Carnarvon Basin, 60 kilometres offshore Western Australia, in a water depth of approximately 47 metres.
The field was developed using a fixed leg, 12-slot manned central processing facility platform with a liquids production capacity of 50,000 bbls/d, of which 30,000 bbls/d is for oil. This is connected, by an eight inch underwater export pipeline, to a pipeline end manifold where shuttle tankers directly load crude oil via a catenary anchor leg mooring buoy.
Hydrocarbons are situated within a combination structural/stratigraphic trapping mechanism of the early Cretaceous M. Australis sandstone reservoirs. Reservoir quality is good with porosities typically in the 18-27% range and permeabilities typically of the order of hundreds of millidarcies.
Gross production from the Stag field in 2024 averaged 2,006 bbls/d. As at December 31, 2024, Stag had gross 2P reserves of 10.3 MMbbls.
The Stag field produces heavy sweet crude (18˚ API, 0.14% mass sulphur), which historically sells at a premium to Dated Brent.
