Buru Energy Ltd (ASX:BRU) has completed the Rafael 1 well in the Canning Basin, in northwest Western Australia some 50 kilometres to the east of the Ungani Oilfield, with the installation of the completion tubing string and the wellhead Christmas tree.
Buru has run and set 144mm tubing inside the 178mm casing, with the section below the casing shoe at 3,868 metres ‘barefoot’ or uncased to maximise the flow potential of the interpreted reservoir section.
The 144mm tubing string was run instead of the proposed 60mm tubing string to provide additional operational flexibility and minimise the potential for wellbore restrictions to oil flow.
The Ensign963 rig was released from site at 24:00 hours on December 2, 2021, and is in the process of being mobilised to the Ungani Oilfield to drill the Ungani 8H well. Buru expects the Ungani 8H well to be spudded before Christmas.
Forward program
It will be several days before well site drilling equipment can be cleared from the wellhead, and test equipment can be mobilised to site.
The production test is planned to begin in mid-December, with timing of all operations subject to weather-related and other operational delays, including current COVID restrictions on interstate personnel movements.
This test program is scheduled to take approximately one week with a series of flow periods and shut-ins to determine reservoir parameters.
The results of the test will be announced after analysis of collected data is complete.
