Another reason for gas to liquid conversion is the 1000x “compression” that occurs.
There is lots of stranded natural gas ie gas that is too far away from viable markets. Currently they flare it. Having the ability to turn this waste product into usable crude is a good thing.
The amount flared is way less than it used be typically done. Places like the Alaskan North Slope now re-compress and inject back in the reservoir the gas produced but not used.
Most of the royalty owners now require payment of the loss of gas if flared. Producing companies are financially penalized now if flared. So if the quantity is significant in a locations, it is either sent to market or back to the field.
