Comparing to the original fracturing ,fluid, whose density was 1.30 g/cc, the density of the ,flowback fluid, decreased with time, indicating the loss of weighting agent into the formation. When the ,flowback fluid, is reused, additional weighting agent might be needed depending on the fracturing job; however, the dosage can be less than the case using the fresh water.
