I'm wondering who are the other shale gas players on the ASX? Is Red Fork energy the most advanced Australian company in terms of Shale gas? I've noticed a few companies starting to mention shale gas as future projects in recent times. These include Beach Petroleum, New Standard energy, Oil Basins. However none have drilled or completed a well. Red fork has successfully completed 6 or 7 (around there) unconventional horizontal drilling and fracturing, and the plans now is to now just drill, drill, drill and produce.
