Exxon and the like are watching this. They will continue to drill, but they are already trying to predict how this will play out to ensure that they have enough wells to supply whatever demand there is in 10 years, while getting the best price from those that are left. They know the writing is on the wall for fuel customers - but there are other customers they have plus collectors.

Note that I did not say they will predict this correctly, only that they are trying to.
