Shales Leaching Modelling for Prediction of Flowback Fluid ...

Flowback fluid differs significantly from the fracturing fluid, as it contains suspended fine rocks as a result of the leaching process, reservoir water, drilling muds, and also various chemical substances, such as dissolved solids (e.g., chlorides, sulfates, etc., measured as total dissolved solids or TDS), suspended solid particles (TSS), bacteria, metals (e.g., calcium, magnesium, barium, strontium), iron compounds, …

Some drilling operators elect to re-use a portion of the wastewater to replace and/or supplement fresh water in formulating ,fracturing fluid, for a future well or re-,fracturing, the same well. Re-use of shale oil and gas wastewater is, in part, dependent on the levels of ,pollutants, in the wastewater and the proximity of other ,fracturing, sites that might re-use the wastewater.

As the fracturing process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the fracturing fluid to deactivate the gelling agents and encourage flowback. Such oxidizers react with and break down the gel, reducing the fluid's viscosity and ensuring that no proppant is pulled from the formation.
