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.
