This fluid contains PHPA (partially hydrolyzed polyacrylamide), which provides shale encapsulation. It protects water sensitive shales from hydrating and sloughing into the wellbore.
Because PHPA is a long-chemical molecule, it can effectively link a number of clay platelets together creating viscosity with a minimum concentration of low-gravity solids. Therefore, a minimum solids fluid can be formulated to maximize ROP and provide good hole cleaning capability.
"We would like to take this time to thank you and commend the entire HiTech team for their involvement."
"Employing the two phased oil based fluid from HiTech Fluid Systems to drill our deep foothills wells, has realized significant cost reductions."
