True or false? Hydraulic fracturing and horizontal drilling have increased oil and gas production in the U.S.
-
Correct!
Extraction of "tight" oil—light crude oil contained in geological formations of shale or sandstone—accounted for only 12% of total U.S. oil production in 2008. By 2012, it made up 35%, and is predicted to rise to 50% in the near term.
