December 2013

Oil Seeps in Arizona
December 2003
Compared to California, Arizona has virtually no oil seeps. But, the great Permian Basin of West Texas has virtually none either. Arizona has something that neither California nor Texas have, and that is public lands that are open for leasing. The northern half of Arizona has more seeps and is thus of greater interest, but it would be foolish to disregard the southern half because giant oil and natural gas fields could underlie some of the broad desert valleys.
