Flow-back treatment involves transfer of flow-back fluids to pits or tanks, and their ultimate removal by truck or pipeline to disposal facilities, and can take up to 14 weeks per well. Well clean-up and testing will involve well flaring and monitoring, preparatory to production, and takes up to four weeks per well.

Normal fracturing techniques include injecting a fracturing fluid ("frac fluid") under pressure into the surrounding formation, permitting the well to remain shut in long enough to allow decomposition or "breakback" of the crosslinked gel of the fracturing fluid, and removing the fracturing fluid to thereby stimulate production from the well.

When a well is hydraulically fractured, frac materials are injected under considerable pressure into a reservoir until the reservoir formation fractures (a process that can last a few days). When the treatment is concluded, the pressure balance is immediately reversed and fluids flow back from the reservoir toward the fractured wellbore.

The fracturing process mainly includes forming fractures by injecting pad fluid, then injecting sand-carrying fluid, and finally injecting displacement fluid. The fracturing fluid should meet the characteristics of little filtration, strong sand-carrying capacity, low friction, low residue, and easy flow back [ 7
