Flowback, could begin right after the ,fracturing, equipment was rigged down (15 to 30 minutes). Cleanup ,fluid, flow rates were up to ten times higher than previously obtainable with curable resin-coated proppants and less proppant was flowed back. Faster ,flowback, rates also resulted in earlier onset of gas production and reduced ,flowback, time.
