PHPA is a anionic Partially hydrolyzed poly acrylamide polymer which is used to stabilize reactive clays and shale formation by inhibitating cuttings and clays in the borehole wall and preventing dispersion. It could be used in fresh to salt water muds.
Application:
* Shale stabilizer
* Encapsulator
* Flocculant
* Viscosifier
