Beach Energy Updates Ops at Moonta Well

Beach Energy Ltd. advised 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 12,500 feet (3,810 meters) 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, Dec. 3, 2012, and spud the Holdfast-2 horizontal well on Monday, Dec. 10, 2012. The well has completed setting surface casing and is now drilling ahead at 5,007 feet (1,526 meters).

The Holdfast-2 well will be drilled horizontally through the Murteree Shale and is located approx. north-east of Holdfast-1. The well is being drilled vertically for approximately 1.8 miles (3 kilometers) and, early in the new year, will commence drilling laterally for approximately 1 mile (1.6 kilometers). 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 12,320 feet (3,755 meters) early Friday morning. Upon de-mobilization 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.
