Microbial, activity in fracing fluids can lead to biofouling, corrosion, and gas souring. Biocides are commonly applied to inhibit ,microbial, activity, but in many cases biocide application is partly or even wholly ineffective. This is, in part, because biocides are rarely tested using real environmental communities relevant to fracing systems.

A ,compound, identified in ,flowback,, 2-n-Butoxyethanol, was also positively identified in one of the foaming drinking water wells at nanogram-per-liter concentrations. The most likely explanation of the incident is that stray natural gas and drilling or HF compounds were driven ∼1–3 km along shallow to intermediate depth fractures to the aquifer used as a potable water source.

As discussed below in Sections 2.3 and 2.8.1, CO 2 fluids eliminate the need of water while providing extra energy from the gas expansion to shorten the flowback time.In general, a fracturing fluid can be thought as the sum of three main components:Fracturing Fluid = Base Fluid + Additives + Proppant A fracturing fluid can be "energized" with the addition of compressed gas (usually either CO 2 or N 2 ).
