was ,fluid, inflow at zones 1 and 2, but not at zone 3. Proppant ,backflow, was identified exactly where the operator had conducted hydraulic ,fracturing,, which is a clear indication that the fracture was not working as per the design intent. Hence the hydraulic ,fracturing, needed complete reassessment and re-design.

In hydraulic ,fracturing, operations, these agents are commonly used as an additive in ,fracturing fluid, to facilitate its ,backflow, by reducing Pc and subsequently enhancing gas production. The results of this work recommend that using such agents enhances the gas production rate for ultratight formations but not for tight formations (it reduces the gas production rate).
