Flowback:Flowback is fluid that returns to the surface with extracted gas. It may contain clay, salts, rock particles, naturally occurring elements dissolved from the rock, and chemicals that were added prior to beginning the hydraulic fracturing process. Most flowback occurs within 7-10 days of drilling, but may continue for 3-4 weeks.

For example, flowback fluid recovered from wells is reported to range from 9% to 35% of the fracture fluid used in the horizontal Marcellus wells in the northern tier of Pennsylvania (Wood et al.) Yoxtheimer (2010) reported an average recovery of flowback of 10% (over 30 days) per Marcellus well.

1/11/2016, · Samples for flowback/produced water were collected over a, 200-day, period (day 0 refers to when flowback began) from two wells. One of the frac fluids had an initial pH greater than 10 and used a guar-based gel and the second fluid contained a non-guar polysaccharide based polymer with an initial pH of less than 6.

At some point, the water that is recovered from a gas well makes a transition from flowback water to produced water. This transition point can be hard to discern, but it sometimes identified according to the rate of return measured in barrels per day (bpd) and by looking at the chemical composition. Flowback water produces higher flowrate over a shorter period of time, greater than 50 bpd.
