1/7/2018, · ,Test, results show that the stability of sand plug in the earlier stage of, production, is mainly affected by, fluid, washing during, flowback,, so it is necessary to control the, flowback, rate strictly. In the later stage of, production,, the stability is mainly affected by, fracture, closure stress and flow pressure, so it is necessary to enhance the yield strength of proppant to maintain high conductivity of, fractures,.

Alum and ferric chloride were evaluated as coagulants for clarification and ,boron removal, from saline ,flowback, water obtained from a well in the Eagle Ford shale. Extremely high dosages (> 9000 mg/L or 333 mM Al and 160 mM Fe) corresponding to Al/B and Fe/B mass ratios of ∼70 and molar ratios of ∼28 and 13 respectively were necessary to remove ∼80% ,boron,.

: A wide range of organic compounds that may be present in formation water (e.g. Orem et al. 2007; US EPA 2011) could physically migrate during the hydraulic ,fracturing, operation. The ,flowback, water would therefore contain compounds introduced within the hydraulic ,fracturing fluid, as well as mobilised water-soluble geogenic organic contaminants.

Abstract: Hydraulic ,fracturing, is considered as an effective approach for the development of tight oil reservoirs. Unlike conventional reservoirs, after a large volume injection of the ,fracturing fluid,, the ,flowback, rate in tight oil reservoirs is considerably lower whereas the underlying mechanism explaining water retention remains unclear.
