No, they can't but all in all total global rigs are one third higher than they were 10 years ago and we are producing less than we did before. Oil companies have lots and lots of leased land. Why is it that they want more and claim that there is oil under the land they don't lease? The fact is that the U.S. is indeed holding back some drilling but the oil they might produce is inconsequential. U.S. reserves peaked in the 70's, We could drill a million wells and we wouldn't be self sufficient. The fields in Texas are in tertiary mode, the ones in Alaska are in secondary, pumping just a fraction of what they used to. There is no true production left in the Continental U.S. I can't, for the life of me figure out why people want to believe fairy tales about what is quite obviously a limited natural resource.
