Stag Oilfield

The Stag oilfield was acquired by Jadestone through its wholly-owned subsidiary Jadestone Australia on November 11, 2016.


The field was developed using a fixed leg, 12 slot manned central processing facility platform with a liquids production capacity of 50,000 bbl/d, of which 30,000 bbl/d is for oil. This is connected, by an eight inch underwater export pipeline, to a pipeline end manifold and Floating Storage and Offloading vessel (“FSO”), via a catenary anchor leg mooring buoy. Shuttle tankers transfer the oil from the FSO to shore.

As at December 31, 2017, Stag had 2P reserves of 17.1 MMbbls (gross and net) with a value of US$84.2 million (NPV10). The field has 3P reserves of 22.7 MMbbls and 2C oil resources of 2.7 MMbbls (gross and net).

The field produces a biodegraded oil with a gravity of 19 API. Oil production peaked at approximately 26,000 stb/d in 2000 but has now fallen to approximately 3,600 stb/d via 11 production wells. Field water production is approximately 22,000 bbl/d and the watercut is approximately 88 per cent.

The Company has planned an infill drilling campaign to drill one new well in 2018, two in 2019 and two in 2020 with an estimated total associated cost of US$112 million.
