Monthly Drilling Report Release Date: 4 October 2017

Senex has drilled 21 of 30 coal seam gas appraisal wells in its Phase 2 drilling program for the Western Surat Gas Project in Queensland, and drilled an oil exploration well in the South Australian Cooper Basin during September.

Surat Basin, Queensland Western Surat Gas Project (ATP 795 and ATP 889: Senex 100% and operator)

Seven appraisal wells were drilled during September with all wells cased and suspended as future gas producers. Senex is on track to bring all Phase 2 wells online by the end of 2017, with the first pod of wells commissioned and gas and water gathering system completed, and well site skids installed for more than half of the 30 wells.

The Phase 2 program for the Western Surat Gas Project focuses on the south-east area of Senex's permits, within the drill-ready blocks Eos (ATP 795) and Glenora (ATP 889). The area is approximately 30 kilometres from Roma and directly north of GLNG's producing Roma field. The campaign is appraising the coal seam gas production potential of the Walloon coal measures with an average well depth of around 430 metres. Refer to the map in Figure 1 showing drilling locations.

Cooper Basin, South Australia Frey-1 oil exploration well (PEL 93: Senex 70% and operator)

Frey-1 is an oil exploration well located in PEL 93 of the south-western Cooper Basin. The well was designed to test the hydrocarbon potential of the top Namur Sandstone and Murta Formation interval in a four-way dip closed anticline, evident at all stratigraphic levels. Frey-1 reached total depth of 1,394 metres on 29 September, failing to encounter significant hydrocarbons and the well will be plugged and abandoned.

Frey-1 will meet the existing well commitment in PEL 93. The well costs were partially funded by Metgasco (ASX:MEL) and local landholder and contractor, Dunns Earthmoving Pty Ltd, to earn an interest in the Frey-1 area through farm in agreements (see map in Figure 2 showing farm in area). Senex contributed approximately 30% of the costs to drill Frey-1.

In line with its strategic priorities for FY18, Senex remains focused on a returns-focused capital investment program in the Cooper Basin and is prioritising spend on a small number of western flank drilling targets with internal rates of return higher than 50% on a success case basis. The company will update the market on its Cooper Basin drilling program in its September quarterly report.
