Speaking as a guy who has royalty rights to 5 nat gas wells, supply and demand has already kicked in on the nat gas biz.
Drilling has been curtailed in TX because the price is low compared to oil. The market of nat gas is limited by the piping network in the US. Unlike oil, nat gas is a regional market.
Based on BTU equivalence nat gas should be about $18 per MCF. It presently is around $4.50 per MCF.
