Beach Energy Updates on Unconventional Exploration Program in Australia

Beach Energy Ltd announced Monday the following in relation to its Australian unconventional exploration program in the South Australian Cooper Basin Joint Venture (SACB JV) (Beach 20.21 percent, Santos Ltd 66.6 percent and operator, Origin Energy Ltd 13.19 percent) and the Nappamerri Trough Natural Gas (NTNG) project in PEL 218 (Beach 70 percent and operator, Chevron Exploration Australia 1 Pty Ltd (Chevron) 30 percent) and ATP 855 (Beach 45.9 percent and operator, Chevron 18 percent and Icon Energy Ltd 40 percent).

The REM exploration program is focused on the Roseneath Shale, Epsilon Formation, Murteree Shale and Patchawarra Formation. This program is being undertaken in the shallower areas of the Nappamerri Trough near existing infrastructure. Three projects have been initiated, namely Aurora, Roswell and Fortuna.

The Aurora project is comprised of the Moomba-192 vertical well and the Moomba-193 Murteree Shale horizontal well. Moomba-192 was drilled to a total depth of 9,776 feet (2,980 meters) in April 2013 and will be used as a monitoring well for down-hole micro-seismic during fracture stimulation of the Moomba-193 horizontal well. Moomba-193 is currently drilling ahead at ~8,858 feet (~2,700 meters), with a lateral in the Murteree Shale planned to be ~3,280 feet (~1,000 meters).

The Aurora project is within 0.62 miles (1 kilometer) of the Moomba-191 vertical well, which is currently producing gas at a rate of ~2 million standard cubic feet per day (MMscf/d) from the three fracture stimulation stages in the Roseneath Shale, Epsilon Formation and the Murteree Shale. Moomba-191 has been producing for 14 months into the Moomba North gathering system.

The Roswell project is comprised of the Roswell-1 vertical well and the Roswell-2 Roseneath Shale horizontal well. Roswell-1 was drilled to a total depth of 10,564 feet (3,220 meters) in December 2012 and fractured stimulated in a deep Patchawarra Formation coal, flowing gas at 0.4 MMscf/d. Roswell-1 will be further stimulated at a later date in shallower horizons, which are yet to be determined. The Roswell-2 horizontal well was drilled to a total depth of 11,417 feet (3,480 meters) with a 1,804 foot (550 meter) lateral in the Roseneath Shale. Fracture stimulation of this section is planned for 1Q 2014, with the well to be monitored using a surface micro-seismic array.

The Fortuna project is comprised of the Moomba-194 vertical well and Moomba-195 Murteree Shale horizontal well. Moomba-194 was drilled to a total depth of 11,049 feet (3,368 meters) in October 2013, with fracture stimulation undertaken over five stages in the Epsilon Formation, Murteree Shale and the Patchawarra Formation. The initial flow rates were 3.1 MMscf/d, which declined to ~1.4 MMscf/d prior to shut-in of the well. The completion equipment for this well have been installed with the well awaiting the installation of a flowline. This well has confirmed the extension of the Patchawarra Formation gas accumulation in the Moomba field, with the operator indicating the results are a step closer to commercialization of the greater Nappamerri Trough.
