There is no way that Santos don't know about this, along with Beach and ALL the others.
If only because LCK would have contacted them + they placed the expression of interest ("Gas for Sale") in the Fin Review.
A straight forward play for Santos would be to run a pipeline from Leigh Creek to Moomba where Santos has a large processing plant (I've seen it, I used to eat dinner, sleep and drink cans of red, blue, green, white or black not 400 metres from it).

LCK are currently in discussions with a few major players - at least one fertilizer company and one MEGA gas company.

This could go a number of ways from here...
- straight out takeover
- investment partner: "we'll pay for the plant, pipeline etc.and take 40% of the company"
- investment partner with OT rights "we'll pay for the plant etc. + take all your gas at X per Gjoule."
- and similarly for a Fertilizer play.
- Mixture of gas and fertllizer may be even power generation.

There are no shortage of commercialization options: the hard work is making a decision because each scenario requires deep analysis.
Normally, the company would do faster broad number feasos on each option and then pick two winners to do more detailed analysis followed by a bankable feasibility on the final option. We are talking two years.

In the meantime, a large player might front-up with a takeover offer - but they will need at least 3 to 6 months to do their analysis.

So, while they have a nice 2P resource, it's minimum 3 to 4 years before it will be converted to revenue.
