The company in 2009 had started drilling exploratory wells on 130,000 acres north of Laredo, and Hart's attitude about the other geologic bands of rock that lie atop the Eagle Ford was this: They were standing between him and the Eagle Ford and needed to be drilled through quickly to get to the real payday.
Then a geologist came into Hart's office with data that indicated that some of those other formations had as much potential as the Eagle Ford.
Hart was skeptical. “I basically said, ‘Get out of my office.'”
