Jadestone Energy plans infill drilling at Montara

Jadestone Energy Inc., Singapore, plans infill drilling at its Montara oil fields project in the Timor Sea about 690 km east of Darwin in 80 m of water.

The Montara development project comprises development of Montara, Swift, Skua, and Swallow fields via the Montara wellhead platform.

The new work includes drilling of one development well (H6) from the platform in production licence AC/L7 with contingencies for a second development well (Skua-12) in adjoining production licence AC/L8.

Jadestone also will perform workovers of the H3 and Skua-10 wells in AC/L7 and AC/L8, respectively.

Skua 12 is a new location about 20 km from the Montara platform while Skua-10 is an existing well. The H6 and H3 well operations will be undertaken with a jack-up rig positioned beside the platform and cantilevered over it.

The new work, scheduled to begin in this year’s second quarter and last about 150 days, is targeting an estimated 5-5.5 million bbl of untapped oil. Montara is currently producing about 10,300 b/d.

Montara fields are estimated to hold a total 2P resource of 28.2 million bbl, of which Montara holds 14.9 million bbl, Skua 6.9 million bbl, and Swift/Swallow 6.4 million bbl.

Jadestone’s drilling plans are being assessed by the Australian regulator, the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).
