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.

A portion of the frac ,fluid, remains in the formation after the ,fracturing, process is complete, which could potentially contribute to deleterious microbially induced processes in natural gas wells. Here, we report on the geochem. and microbiol. properties of frac and ,flowback, waters from two newly drilled natural gas wells in the Barnett Shale in North Central Texas.
