----- Section 5-Wastewater Characterization and Management In wells that are hydraulically fractured, ,fracturing, fluid - typically consisting of water, a number of chemical additives and a proppant (such as sand) - is pumped down the well bore under pressure to create and hold open fractures in the target formation that allow for the flow of oil and ,gas,. Some ,fracturing, fluid, as well as water from the formation, returns to the surface as ,flow-back,.

Mechanical Weathering Mechanical weathering is the physical breakdown of rocks and minerals. Some is the result of ,fracturing, due to the volumetric increase when water in a crack turns to ice, some is the result of abrasion during transport by water, ice, or wind, and a large part is the result of gravity causing rocks to fall and shatter.

This water comprises both ‘,flow-back,’, i.e., returned drilling and hydraulic ,fluids,, in addition to ‘produced’ water, consisting of formation brines from the hydrocarbon reservoir and extracted along with the oil and ,gas,. The proportion of ,flow-back, and produced water from a given well changes over time with the latter making a greater contribution (>90%) as the asset ages (e.g., ).

There are many different types of ,gas separation membrane,, including porous inorganic membranes, palladium membranes, polymeric membranes and zeolites Membranes cannot usually achieve high degrees of ,separation,, so multiple stages and/or recycle of one of the streams is necessary. This leads to increased complexity, energy consumption and costs.

The fracturing fluid mixture after extraction is referred to as “flowback fluid,”, the recovered water and fracturing fluid which flow back from oil or gas well drilling fracturing operation., This flowback fluid typically can be anywhere from 10-60% percent of the volume of fluid that is injected into the well, and it flows back over a period of several days to several weeks or longer after fracturing.
