Lindsey Hufnagel McCarty, vice president of reservoir engineering and business development at PayRock Energy II, is today’s Forty Under 40 featured honoree.

PayRock II formed with backing from EnCap Investment LP after the successful sale of its predecessor company for $888 million to Marathon Oil Corp. in 2016. Headquartered in Oklahoma City, the company focuses on the acquisition and exploitation of assets within the Anadarko basin.

Lindsey, who previously worked as an engineering supervisor on Marathon’s Eagle Ford subsurface team before joining PayRock II, said the biggest professional challenge she has faced in her career so far involved stepping into a leadership role in a high-profile asset with no previous experience in unconventional resource plays.

“I had to learn the intricate processes required to successfully develop a shale play on the fly, while simultaneously learning how to lead a team with 13 rigs running during the worst commodity pricing downturn in decades,” she said. “It was incredibly humbling and not something I want to go through again, but I gained dog-years of experience and learned a lot about myself in the process.”
