Shale Fluid

Escaid™ PathFrac™ fluid

Escaid PathFrac fluid is a very low total aromatic content fluid developed for hydraulic fracturing formulations. It enhances the properties of fracturing fluids while supporting your commitment to protect the environment and the health of workers.

Purified by an advanced hydrogenation process, Escaid PathFrac fluid effectively facilitates the delivery of friction reducers and viscosity modifiers into the fracturing fluid formulation. Escaid PathFrac can also be used as an effective barrier fluid in emulsified acid applications, and as a gelled diesel replacement for oil-based applications.
