well they sure enough did a good job squezzing service companies to lower their fracking costs.
Squeezing.
Because they were just too high. It is only sand, water, horsepower, fuel and people.
Fracing was so profitable it was attracting all kinds of vulture capitol. It was so profitable that several operators were seriously considering building their own frac spreads.
This cost reduction is not one of cost sharing it is reducing profit.
