A two-well oil appraisal campaign commenced in the Chiton Field, located approximately two kilometres south of the Bauer Field.  The campaign is designed to appraise the extent and productivity of the McKinlay Member to the south and east of currently producing wells, where there has been limited appraisal drilling to date.  Chiton-4, the first well of the campaign, was plugged and abandoned due to lack of commercial pay.

A two-well oil exploration campaign was undertaken in the western block of PEL 630, located approximately 60 kilometres northeast of the Bauer Field.  The wells are located outboard of existing oil discoveries to test a possible northern extension of the Namur and Birkhead play fairways.  Butterfish-1, the first well of the campaign, detected trace oil shows within the Birkhead Formation, however the Namur Sandstone primary target was water bearing.  No oil shows were detected in the second well of the campaign, Harvey’s Return-1.  Both wells were plugged and abandoned.  Results from the campaign have helped refine the northern extent of the oil play fairways.

A three-well oil exploration campaign was completed in PEL 182, located approximately 25 kilometres northeast of producing fields in ex PEL 104 / 111.  The campaign tested the extent of hydrocarbon migration to the north of the Western Flank, with prospects targeting the Namur Sandstone (primary objective) and Birkhead and Murta formations (secondary objectives).  The final well of the campaign, Immortals-1, was plugged and abandoned due to lack of commercial pay.  The campaign improved definition of the Namur and Birkhead play fairway boundaries.

A two-well oil development campaign was completed in the Pennington Field, located approximately 10 kilometres east of the Bauer Field.  Reservoir simulation modelling identified potential for improved field commerciality through in-fill drilling to accelerate production.  The wells targeted the Namur Sandstone as a primary objective and the McKinlay Member and Mid-Namur Sandstone as secondary objectives.  Pennington-6, the second well of the campaign, was cased and suspended as a future producer following intersection of four metres of net oil pay in the Namur Sandstone, four metres of net oil pay in the overlaying McKinlay Member, and one metre of net oil pay in the Mid-Namur Sandstone.

A five-well oil development and appraisal campaign was successfully undertaken in the Callawonga Field.  The campaign was designed to develop oil reserves in the McKinlay Member and appraise the extent and productivity of this reservoir.  The Namur Sandstone was targeted as a secondary objective. 
The campaign proved successful with all five wells (Callawonga-14 to -18) expected online in Q2 FY18.  Four wells intersected oil columns high to prognosis, indicating extensions of field limits with 2P reserve additions expected.  Namur columns were also intersected at three wells which will allow earlier connection and acceleration of production.  The campaign also provided evidence to support additional in-fill development drilling, with planning of a future five-well program currently underway.
