Contributor Brock Yordy joined the National Driller team at the National Ground Water Association’s Groundwater Week 2019. This is one of several interviews recorded live at the event for our Ask Brock video series.

In episode 60 of Ask Brock, our host speaks with Rex Penry, owner of CP Drilling in Leedey, Oklahoma, who drills Oklahoma, west Texas and New Mexico. “There’s no such thing as swelling clay, only the excuses drillers use when they hit swelling clay,” Penry says. Check out the latest episode to hear his tips on how to minimize excuses and maximize productivity.
