3 Sept 2026drilling result▲ GoodMajor
Logs and mud logs show a third oil zone, the M sand, in Bunian 6. It has not been seen before in the Bunian field but is the main producing zone in the neighbouring Tangai field. It will be tested when the well starts; reserve impact is yet to be quantified.
26 Aug 2026drilling result▲ GoodMajor
Bunian 6 reached 1,807.9 m and logs show oil pay in the TRM3 and K1 sandstones, in line with pre-drill expectations. It will be completed as a producer and come online in early September, targeting field output rising from 250 to 750 bopd. Well flow rates are not yet tested.
21 Aug 2026drilling progress report● Neutral
A replacement top drive got Bunian 6 drilling again, reaching 1,573 m of a planned ~1,820 m. Logging and completion are now expected by end of August, with production shortly after. No result yet.
20 Aug 2026production update● Neutral
July sales were A$405,527 as rain stopped Cooper trucking, though output held at 221 bopd. Trucking restarted in August (1,548 barrels at A$125.04). Vanessa engineering continues with a pipeline survey due September; Kiwi 3D reinterpretation is encouraging.
14 Aug 2026drilling progress report▼ Bad
Bunian 6 casing was cemented and the wellhead and blowout preventers tested, but the rig stopped at 1,257 m to repair the top drive hydraulics. Drilling of the final section is yet to restart. Online still stated as late August, which now looks tight (inference).
7 Aug 2026drilling progress report● Neutral
Bunian 6 was drilled to 1,257 m, the intermediate casing depth, and the rig was running the 9-5/8 in casing. Next: cement it and drill the production hole to about 1,820 m. Online still stated as late August. No result yet.
31 July 2026drilling progress report● Neutral
Bunian 6 drilling resumed after the mud pump fix and reached 1,144 m. Intermediate casing point is now about 1,300 m, then the production section to about 1,820 m. Online still expected late August.
28 July 2026quarterly activities report▲ Good
June quarter oil sales were A$2.67m at an average A$143.49 per barrel, up 132% on March, helped by selling stored Cooper oil. Cash was A$3.18m, debt free. Vanessa completed; Bunian 6 now expected online late August.
24 July 2026drilling progress report● Neutral
A replacement mud pump was installed at Bunian 6 and was being tested at 1,012 m before drilling resumes. Plan is to finish this section to about 1,440 m, then set casing. Online still late August.
17 July 2026drilling progress report▼ Bad
Bunian 6 drilling is suspended at 1,012 m awaiting replacement mud pumps, with restart expected around 24 July. The online date moves from early July to late August, a delay to the extra production Bass is targeting.
17 July 2026production update● Neutral
June sales revenue was A$561,477, with group output averaging 225 bopd. Cooper sales were cut by rain closing roads. Bunian 6 is now due online late August, later than the early July previously given. Vanessa completed mid-June.
10 July 2026drilling progress report▼ Bad
Bunian 6 reached 1,012 m, only 117 m of progress in the week, and the rig stopped for mud pump repairs. The report still says online early July, though the drilling has not reached the casing point.
3 July 2026drilling progress report● Neutral
Bunian 6 was drilled from 403 m to 895 m this week, heading for about 1,400 m before intermediate casing. Total depth is still about 1,820 m. The report still says online in early July, which looks unlikely given the depth so far (inference).
26 June 2026drilling progress report● Neutral
Bunian 6 surface casing cementing was completed and the blowout preventer installed and tested after some rig repair downtime. Drilling the next section from 403 m continues. Online date still stated as early July. No result yet.

9 June 2026drilling spud▲ GoodMajor
Drilling of Bunian 6 in Indonesia began 5 June, about a month later than the 'early May' timing previously given. It targets ~1,820 m over about 30 days, aiming to lift field output from 250 to 750 bopd, online early July. Bass (55%) rates success at 80%; cost recoverable.
