Beach Energy Update on Cooper, Eromanga Basins
Beach Energy has provided the following Update on the outcome of their efforts with regards exploration and Appraisal.

A six‐well infill development drilling campaign was completed in the Moomba North Field, which aimed to develop booked reserves in the Toolachee, Daralingie and Patchawarra formations. A phased approach is being undertaken which may result in drilling up to 26 new wells in the area, six of which were drilled in 2014.
Outcomes from the 2014 campaign were applied to the current
campaign, including optimised well designs and improved well completions. During the month, the final two wells of the campaign, Moomba‐207 and Moomba‐208, intersected gas pay broadly in‐line with pre‐drill estimates. The completed drilling campaign proved successful, with all six wells cased and suspended as future producers.
EXPLORATION AND APPRAISAL
Ex PEL 106
(Beach 50% and operator, Drillsearch 50%)
A two‐well exploration program commenced on the western edge of the Patchawarra Trough, which aims to add reserves in the liquids rich gas play area. The first well of the campaign, Middleton East‐1, is located approximately 1.5 kilometres east of the producing Middleton‐1 well and targeted the Patchawarra Formation, with the Tirrawarra Sandstone providing a secondary target. Prospects were defined on the Irus 3D seismic survey, acquired in 2012 and reprocessed in 2013. Middleton East‐1 was cased and suspended following initial interpretation of wireline petrophysical and pressure data, which indicated six gas zones and net pay of 9.3 metres, including 4.9 metres intersected within the primary target zone. Extended production testing is expected to be undertaken at a later date to better assess flow rates and resource base.

(Beach 40% and operator, Drillsearch 60%)
A two‐well oil appraisal program was completed in the Bauer Field to test southern and northern extensions of the field. Bauer‐25, the second well of the campaign, is located on the northern flank of the Bauer Field and is the northern‐most well in the field. The northern flank is a low relief area extending to the Bauer North‐1 discovery well, approximately 1.3 kilometres northeast of Bauer‐25.
The well targeted the McKinlay Member and Namur Sandstone reservoirs, with the Birkhead Formation providing a secondary target. The well was cased and suspended as a future producer following intersection of a two metre net oil column in the Namur Sandstone and a 3.5 metre gross oil bearing interval in the overlaying McKinlay Member. Further evaluation of results will be undertaken to assess potential for follow‐up drilling.
