latest stats show production of just under 9 million barrels per day in May, 2016 according to eia.
rig counts dropped as the price of crude dropped because fracking costs more than traditional drilling
all in all it matters not. the following two issues are always in play:
economically recoverable vs technically recoverable and er/ei. of the two the latter is least understood most likely by the general public.
largest exporter to the u.s. is canada. opec supplies a little over one third of our imports. canada may not be exporting crude but oil equivalents in the form of tar sands.
the bottom line re: fracking is the service life of oil wells and gas wells is not the same as conventional drilling. i have not seen calculations for the amount of energy expended in fracking including construction, transportation of water, fracking fluids etc. we also do not have much assurance other than their word (and that is not worth much) that fracking is safe.
