Bass Oil has reported that production testing of the newly-drilled Bunian 5 well in Indonesia has concluded strongly and production is set to commence from the TRM 3 sandstone reservoir.
The production testing over the TRM 3 sandstone delivered a stabilised average flow rate of over 860 barrels of oil per day at a 3.5 per cent water cut and a 100-psi flowing wellhead pressure on 64/64-inch choke.
Testing over the K sandstone delivered a stabilised average flow rate of over 650 barrels of oil per day at 35 per cent water cut and a 490-psi flowing wellhead pressure on a 34/64-inch choke.
The results confirmed that Bunian-5 had a prolific capacity from the two productive zones, the TRM3 and the K reservoirs.
Bass outlined that the productive potential of the two secondary reservoirs encountered during the drilling, the TRM0 and the GRM sandstone will be further elevated as the data from the well is used to update the field models.
Managing director Tino Guglielmo said the excellent flow results from the “TRM 3 and K reservoirs demonstrated that a significant amount of production capacity remained 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,” Guglielmo said.
“Bunian-5 was a vertical well and took 23 days to drill complete, reaching a total depth of 1662 metres.”
