I would posit that key data for the Lockyer Deep-1 well to come out of the wire line log analysis will be net pay and porosity in the Kingia/High Cliff sandstones and the extent of the gross gas column and if a gas /water contact is observed from formation sampling pressure gradients.

The net pay and porosity will provide some indication of expected flow rate on production testing by comparison with existing Deep Permian gas field production testing results.

The larger the gross gas column, the larger the reserve estimate for the gas field given the assumption of uniform net pay sands over the mapped prospect/structure.

For interested posters, the 'Bible' on the Deep Permian Kingia/High Cliff sandstone gas fields for the North Perth Basin is the published 2016 APPEA paper by Neil Tupper, "The Waitsia Field, Onshore North Perth Basin, Western Australia". This paper is freely available on the web.

Pertinent observations from the Waitsia paper are that for the Deep Permian Gas Fields discovered and described in the paper, it appears that trapping faults are sealing, both upthrown and downthrown and valid closed structures are filled to spill point.

Subsequent data on the West Erregulla Gas field released by Strike Energy adds to the knowledge of the characteristics of Deep Permian gas fields, especially net reservoir pay and production testing flow rates in a more proximal area to Lockyer Deep.

The wire line log results from the Lockyer Deep Permian gas discovery and subsequent production testing will tell if this discovery conforms to these observations and add further to the knowledge of this significant new North Perth Basin Permian gas play.

Once the Lockyer Deep-1 wire line log results, followed by production testing are released to the ASX, more informed range of possible reserves can be made by the operator as to the potential recoverable gas reserves at Lockyer Deep and what it may also portend for the prospectivity of other possible drillable structures that may arise from the prospect and leads shown to date in the Minres/NWE permits as released to the ASX by NWE.

Certainly very interesting times ahead for NWE shareholders.
