1. n. [Drilling Fluids] A class of water muds that use partially hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud.As a shale-control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration.

Shale Inhibitor Mechanism & Products – Drilling Manual

A shale-protective, water-base drilling fluid containing a high molecular-weight, partially hydrolyzed polyacrylamide and potassium chloride has been used in many wells around the world. A laboratory test for evaluating the ability of water-base muds to protect stressed shales under dynamic conditions was used in the initial development of the system.

The shale formation drilling often generates a wide range of problems if ordinary water-based muds are employed. Furthermore, the alteration of shale formation has complicated the development of adequate drilling fluids. The con­trol of shale instability by the exchange of potassium cations with shale structure is well accepted in the drilling fluid industry. In the cases where seawater or …
