Bass Oil Ltd (ASX:BAS) has concluded production testing of the recently drilled Bunian 5 well after delivering a stabilised average flow rate of over 860 barrels of oil per day over the TRM 3 sandstone.
The testing over the K sandstone delivered a stabilised average flow rate of over 650 barrels of oil per day at a 35% water cut and a 490 psi flowing wellhead pressure on a 34/64 inch choke.
The well is now being brought online initially from the TRM3 reservoir with production being ramped up to the field oil facility export limits.
This result confirms that Bunian-5 has a prolific production capacity from the two productive zones, the TRM3 and the K reservoirs.
Field and reservoir models update
The productive potential of the two secondary reservoirs encountered during drilling, the TRM0 and the GRM sandstones will be further evaluated as the data from the well is used to update the field models.
Bass Oil managing director Tino Guglielmo said: “These excellent flow results from the TRM 3 and K reservoirs demonstrates that a significant amount of production capacity remains at Bunian Field.
“The team has commenced updating the field and reservoir models to update the reserves and determine the future development potential in the field.
“This work will inform the drilling program for 2020”.
Bunian-5 was a vertical well and took 23 days to drill and complete, reaching a total depth of about 1,662 meters.
