how many drills & frack spreads in australia?

hey folks,

Not really sure where to put this, but since NSE is on the look out for new drill, let's have a go here.

any know of how many shale frackng spreads & drills are in Australia?

We have quite a few companies undertaking exploration:
AJQ
AWE
BPT
BRU
CTP
DLS
DTE - soon?
ICN
LNC - soon?
NSE
NWE
REY
SXY
TTE


Is this industry constrained by the limited number of drills?

Many of the above listed companies have already conducted vertical fracks and are soon to move to the stage where they will need to some horizontal drilling & fracking.

How many are there in Australia? Will there be enough to each to complete their annual programs?


14 companies listed above and I know 2-3 of them have overlapping JV's, but that's still quite a few companies who will need their own drill and frack spread.

Is the industry constrained by the lack of equipment?
How badly if at all?
