Why are deeper zones to be considered as conventional.

2750-2900m Caryngina shale gas
2900-3085m Irwin river coal measure, tight gas

3085m ---GWC--- Warradong-1 drilled in 1981
GWC at 3185m The common contact suggested the two wells may have intersected the down-dip portion of single large gas accumulation. That includes both Irwin and Synaphea structures.

3146m Dongara/Wagina
3153m Kingia
3171-3183m 10m perforation intervals
3192m High Cliff sandstones
3370m Senecio-3 drilled 2014 flowed test avg 12.3mmscf/d
This will be flowed test at various chock settings after an extended pressure build up SURVEY.
Senecio-1 and S2 were side-tracked in an attempt to improve the nature of TIGHT gas reservoir. In 2011 a FRAC applied over 5m perforation interval delivered a stable gas flow at 1.35mmscf/d from Dongara/Wagina formation.

3432m ---GWC---

3490m Holmwood shale
3507m Waitsia-1 appraisal well
3803m Waitsa-2 appraisal well
4049m Irwin-1 exploration well drilled 4-2015
Data and drilling logs have been evaluated before next phase of activity
4153m Top mapped structure, 10m prognosis
Below this has lack of exploration data.

GWC (gas water cap)
Is a transition zone. 100% above is gas and 100% below is water.
To hit gas OR water is up to the explorer's skills
How deep is the water bearing. A water leg must be found.
An older reservoir encountered two GWC
The two GWC prove that the transition zone is SHALLOWER. This means a deeper gas cap.
Top transition zone must be flow test
The target of W1 and W2 are deep enough to be considered as TIGHTgas play. Ex NTNG in SA. S1 and S2 were the proofs.
Tight gas is normally having a LOW permeability.
The lower permeability in this case gives a longer transition zones. Therefore the Waitsia basin show a conventional play across the acreage.

In my view this W1-W2 will be proved to be a BCG (basin centred gas)
