Bass Oil Limited (ASX:BAS) has drilled the Bunian 5 well to the intermediate casing setting depth of 1315 mKB (metres below kelly bushing) following the spudding of the well on September 24, 2019.
This morning the rig was running a wiper trip prior to running wireline logs in the intermediate section of the well.
The well will be drilled to a depth of 1700 mKB and is expected to intersect the primary target at 1392 mKB.
Bass has acquired a 55% interest in the Tangai-Sukananti KSO producing assets in the prolific oil and gas region of South Sumatra, Indonesia.
Bunian-1 and Bunian-3ST2 are currently in production.
As at July 2019, the Tangai-Sukananti KSO was producing on average 750 barrels of oil per day from four wells (JV share).
Bunian-5 is a vertical well being drilled from the surface location of the Bunian-4 deviated well.

The well is estimated to take 30 days to drill and complete, reaching a total depth of about 1700 metres.
In the success case, Bunian-5 will be completed and brought into production immediately.
Following acquisition of the wireline logs the 9-5/8” intermediate casing will be run and cemented in place.
Drilling operations will recommence towards the first core point at the primary target, the TRM3 sandstone.
