REVIEW OF OPERATIONS
In September 2014, a CoiledTubingUnit (
CTU
) cleaned out the
Geoffrey-1well prior to perforating a single zone in the Lower
Patchawarra and conducting an injectivity test.This activity is
designed to determinewhether the lowermost interval in this
well will be stimulated prior to being tested. Following testing of
the lowermost interval inGeoffrey-1 and, subject to JV approval,
shallower formationswill subsequently be stimulated and flow
tested in order to evaluate the flowcharacteristics of those
individual formations.This step by step processwill lead to a
better understanding of the overall gas deliverability from thewell.
In December 2013 the Redland-1 vertical well, located
22km North-west of Geoffrey-1, was drilled to a depth of
3,804 metres to evaluate the shale and basin centred gas
play in theToolachee and Daralingie Formation intervals
in the north of the permit. TheToolachee and Daralingie
formations penetrated exhibited significant gas shows. A
Notice of Petroleum Discovery was lodged with DNRM for
Redland-1.
The Etty-1 vertical well, located 9km to the east of Halifax-1,
was drilled in February 2014 to a depth of 3,807 metres
to evaluate the basin centred gas potential of the Permian
Formations from the top of theToolachee to the top of the
Patchawarra Formation. The well intersected gas throughout
the Permian section therefore supporting the hypothesis of
a basin centred gas play. A Notice of Petroleum Discovery
was lodged with DNRM for Etty-1.
With the drilling of Etty-1, the sixth well in ATP 855, the
JV has completed the mandatory work program that
included the 423km Gallus 2D seismic survey which was
completed in April 2012.
