Feb 23, 2022 · Most water-soluble polymers such as polyacrylamide tend to hydrolyze/degrade in high salinity (ions such as Na +, K +, Ca 2+, and Mg 2+). At critical concentrations of saline, the polymer might flocculate and precipitate. Therefore, a polymer with good salt resistance is desirable when fracturing in such high-salinity shale reservoirs.

This grease type is often called non-melt lubricant because it has no known dropping point. Its main properties are temperature change resistance, great wear and tear protection, exceptional water tolerance, good mechanical or shear stability, and impressive adhesiveness.
