Australia's Buru Energy Limited provided Tuesday the following update on drilling operations at the Ungani 3 well in exploration permit (EP) 391 in Western Australia as at 06:00hrs, Feb. 25 (AWST).
The well has been drilled to a total depth of 8,356 feet (2,547 meters) MD, or measured depth, within the Nullara Formation. A comprehensive suite of logs has been run over the open hole to evaluate the Ungani Dolomite and Nullara Limestone intervals. The logs identified a fracture zone at the top of the Ungani Dolomite coincident with the elevated gas readings recorded whilst drilling this section. Attempts are currently being made to acquire pressure and fluid samples over the fracture zone utilizing a wireline formation tester. Following that, rotary sidewall cores will be acquired to sample throughout the Ungani Dolomite interval.
The Ungani 3 well is located some 3,280 feet (1,000 meters) to the east of the central Ungani Field area on what is interpreted from the 3D seismic data to be a separate structure. The forward program will be to suspend the well for future entry following evaluation of the well results integrated with the final processed 3D seismic data.
