Deploying Phosphate-Free Dispersants in Air Development
In Ask Brock, episode 146, host and drilling trainer Brock Yordy talks about using dispersants or thinners during air development. In today’s question, Carson from Texas wonders about correct application of a phosphate-free dispersant in a 10-inch well.
Yordy focuses about the purpose of these products: breaking up filter cake.
“These dispersants and thinners aren’t designed to break up other solids,” Yordy says. “They’re really looking for bentonites and clays, and those types of things. If we’re forcing in ultra-fines and that type of stuff, the only way we’re getting that back out is with good surging, and we’re going to use air.”
He also talks about compressors, borehole volume, recommended mixing, swabbing and other topics. Check out today’s episode to hear more.
