FG60:thickening agent in ,acid fracturing, process (Temperature-controlled variable-viscosity ,acid, system) I. Product info: The specificity of this product is that its viscosity rises when the temperature does. It relies on the reaction between thickening agents and cross-linked agents at different temperatures, resulting in different viscosities.

Hydraulic ,fracturing, of shale generates brines with complex chemistries. As such, these fluids have trace metal constituents that can be rendered valuable if concentrated. This project used samples of hydraulic ,fracturing flowback fluid, from the Utica/Point Pleasant formations in Ohio to analyze how different additives of acids and bases could influence precipitation and sequester trace metals.
