Bunian-5 oil production delivers “excellent” flow results for Bass


Australia’s Bass Oil Limited has announced that the Bunian 5 well commenced production testing from the TRM 3 sandstone, one of the two productive oil reservoirs in the well.

The well averaged 1128 barrels of oil per day with a two percent water cut. Production was recorded on a fully open choke with a flowing wellhead pressure of 140 psi in the first 12 hours, commencing on 2 November 2019. The well has been choked back for the next phase of the testing program. All oil produced from the test will be trucked and sold along with all other oil produced from Tangai Sukananti.

The well was cased and completed as an oil producer from both primary targets the K1 Sandstone and the TRM3SS Sandstone. This result confirms that the Bunian 5 well is expected to double overall production from the Bunian Field.

Following completion of the seven-day production test over the TRM 3SS reservoir the well will be switched to the K1 reservoir to commence a similar testing program. The well will then commence production on the optimum parameters.

Bass Oil Managing Director, Tino Guglielmo, said “this excellent flow result from the TRM 3 reservoir, the first of two known prolific oil producing zones, demonstrates that a significant amount of production capacity remains at Bunian Field. We congratulate the team on a safe and successful campaign, and we look forward to further positive results from the production testing in the coming days”.

Bunian-5 was a vertical well and took 23 days to drill and complete, reaching a total depth of approximately 1,662 meters.
