Buru Energy Limited (ASX: BRU) has commenced preparations for production testing at its recently spudded Rafael 1 exploration well with a 4½ inch (114mm) tubing having been run and set inside the 7 inch (178mm) casing. The interpreted Ungani Dolomite reservoir section below the 7 inch casing shoe at 3,868 metres has been left “barefoot” or uncased to maximise the flow potential of the interpreted reservoir section.
The Rafael production test is expected to commence in mid December, subject to weather related or other operational delays, including current COVID restrictions on interstate personnel movements. The test program is scheduled to take approximately one week with a series of flow periods and shut-ins to determine the reservoir parameters.
The Rafael 1 well is located in Exploration Permit EP 428 in the Canning Basin in northwest Western Australia some 50 kilometres to the east of the Ungani Oilfield. Equity in the permit and the well is held 50% each by Buru (JV Operator) and the Origin Energy Limited Group.
The Ensign 963 rig is currently being mobilised to the Ungani Oilfield, with the Ungani 8H production well expected to spud prior to Christmas.
