SINGAPORE – Jadestone Energy has issued an update on its production improvement program for the Montara facilities in the Timor Sea offshore northern Australia, which the company acquired late last year.
These were averaging production of 7,628 b/d last October.
The schedule for 2Q and early 3Q includes replacement of the subsea umbilical from the Skua and Swift/Swallow subsea wells to the company’s FPSO; and a riser-less light well intervention program to restore gas lift to the Skua-11 and Swift-2 wells, perforate additional sands in the Swallow-1 well, and produce new volumes in the Skua-11 well.
These measures should deliver a further 3,200 b/d later in the year, at the same time ensuring continued production from Swift-2 and Skua-11.
Later this year Jadestone plans to drill its first infill well at Montara, subject to rig availability. The H6 well will use an existing slot on the Montara wellhead platform and will target 1.8 MMbbl of 2P reserves, at an initial rate of around 3,000 b/d in 2020.
In addition, the company will commission a new 3D seismic survey designed to improve reservoir imaging, assist placement of future infill wells, and assess further step-out opportunities.
