... and gravity separation. A final method of treatment is diluting the flow back fluid with new fluid. As with any fracture treatment, not all the treatment fluid is recovered and topping off with new fluid can be a method of bringing the flow back fluid into specification. The fluid management is done...

... but they are also expensive and may impair the economic results of fracturing, especially for low permeability reservoirs. This paper presents a new fluid system that is formulated to maximize the economic return of fracturing in low permeability shallow oil reservoirs. It is a solid free linear synthetic polymer...
