1/1/2018, · 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.
