The company has identified a sandstone reservoir at the top of the Anderson formation at a depth of 1,560 m. The reservoir has a good permeability of 450 md. Oil was subsequently recovered to the surface.
Buru reported that interpretation of pressure data indicates an oil column at least 14 m thick with about 5 m of net pay. The company is currently logging and taking samples to confirm and evaluate the find.
Once this operation has been completed, drilling will continue to the top of the main target Ungani Dolomite reservoir where 5-in. casing will be run. The company will then bring in a specialist coring rig to core through the dolomite reservoir section.
Although oil has previously been found in and produced from the Anderson formation in the Canning, this was on the Lennard Shelf in the company’s Blina field permits 125 km away on the other side of the basin.
The Ungani Far West discovery is a significant new play in the Ungani region and upgrades numerous surrounding leads and prospects in the shallow zone overlying the main dolomite reservoir.
