This week, host and drill trainer Brock Yordy talks about the difference between the use of fluids on HDD projects versus other types of drilling — particularly when it comes to volume. It’s Ask Brock episode 127.

“The dynamics of drilling horizontally versus vertically are much different,” Yordy says. “We have physics and gravity that are completely changing the way that we move solids out of the hole.”

He also discusses soil ratios, frackouts and the importance of maintaining flow through the bore. Click the video to hear more.
