When the ,fluids, are treated for ,recycling, for hydraulic ,fracturing,, they may either be treated in the field or transported to a centralized treatment facility via tanker truck. Typically the produced ,fluids, are treated to the extent that they can be injected back down into the ,shale, without plugging up the formation or otherwise negatively impacting oil or ,gas, production.
