After pumping has finished, the fracking ,fluid, (including natural contaminants) returns to the surface. As with initial water demand, ,flowback, volumes are variable. In US operations the volumes returning can be 5–50% of the injected volume (King, 2012). Over a period of a few days to a few weeks ,flowback, decreases and gas production commences.

Borrowing from many years of experience with interwell tracing, several families of non-radioactive chemical compounds were identified that could potentially be placed in segmented portions of the frac ,fluid, so as to more directly measure the ,flowback, efficiency of each ,fluid, segment. Armed with this ,flowback, profile data together with the net pressure history of the frac ,treatment,, it was believed that much could potentially be learned both about the dynamics of segmented ,fluid, …
