The Permian Basin can trace its roots back to 1925, when the first well was drilled there. Long thought to be a sleeping giant, this oil-prone play is experiencing a revival of activity with growing industry interest in unconventional resource plays and new technology. Reports estimate that the Permian holds approximately 29% of estimated future oil reserve growth in the U.S. due to advances in horizontal drilling and significant investment from some of the largest oil and gas exploration companies in North America.
