Moonta-1 Vertical Well Flowing Back Gas and Stimulation Fluid
Adelaide, Dec 21, 2012 AEST (ABN Newswire) - Beach Energy Limited (
ASX:BPT) advises the following in relation to its Cooper Basin Nappamerri Trough unconventional gas exploration program, targeting the Permian section of PEL 218 (Beach 100%).
Moonta-1 vertical well
Flow back of the Moonta-1 well has commenced, with the wellhead choked back during early flow back of stimulation fluid and gas, which is flowing at a rate of 1.1 MMscfd and rising. Approximately 10% of the fracture stimulation fluid has been recovered to date.
The well reached total depth at 3,810 metres after which a ten stage fracture stimulation program was completed, with nine stages in the deeper Patchawarra Formation and one in the shallower Murteree Shale. Flow testing is planned to continue for at least one month, after which the well will be shut-in to allow for the monitoring of pressure build up and stimulation of the shallower zones at a later date.
Holdfast-2 horizontal well
The Ensign 965 rig was released from the Marble-1 vertical well on Monday, 3 December 2012, and spudded the Holdfast-2 horizontal well on Monday 10 December 2012. The well has completed setting surface casing and is now drilling ahead at 1,526 metres.
The Holdfast-2 well will be drilled horizontally through the Murteree Shale and is located approximately one kilometre north-east of Holdfast-1. The well is being drilled vertically for approximately three kilometres and, early in the new year, will commence drilling laterally for approximately 1.6 kilometres. It is anticipated that the well will take two and a half months to reach total depth, after which it will be fracture stimulated around April 2013. The fracture stimulation of Holdfast-2 is planned to be 15 stages, with pumping rates of 80 barrels per minute targeted for each stage.
Streaky-1 vertical well
A nine stage fracture stimulation program has been completed at Streaky-1, with eight stages in the deeper Patchawarra Formation and one stage in the shallower Murteree Shale. The workover rig will be deployed in the new year to install production tubing for the flow test.
Boston-1 vertical well
Total depth was reached in the Boston-1 well at 3,755 metres early this morning. Upon de-mobilsation from Boston-1, the Ensign 916 rig will be relocated to the Nepean-1 vertical well location where it will drill the next unconventional exploration well in the program.
