🛢️ HDD Fluids (Bentonite Polymer Slurry Annular Velocity FPM, Yield Point & Hole Clean)

HDD Drilling Mud Hydraulics Calculator

Size mud mixing pumps, determine sodium bentonite / PAC polymer dosage, and calculate annular flow velocity for Horizontal Directional Drilling (HDD) slurry circuits: calculate cuttings transport ratio (maintaining annular velocity between 120 and 200 FPM with Yield Point YP > 20 lbs/100 sq ft to prevent hydraulic hydro-fracture and stuck drill pipe), and fluid margins.
