This Is the Drilling Method for Most US Oil But Regulators Offer Almost No Oversight

Hydraulic fracturing (“fracking”) and offshore drilling garner a lot of news headlines when it comes to oil and gas issues in America, but they’re far from the only game in town, with those two drilling techniques not even constituting the majority of U.S. oil and gas production. For that, look to enhanced oil recovery (EOR), an under-regulated drilling method that has been around for over a century and could be threatening drinking water sources

Has U.S. oil production started to turn down?

The plunge in oil prices last year led many to say that a decline in U.S. oil production wouldn’t be far behind. This was because almost all the growth in U.S. production in recent years had come from high-cost tight oil deposits which could not be profitable at these new lower oil prices. These wells were also known to have production declines that averaged 40 percent per year.
