Proppant ,flowback, following ,fracturing, treatments can be controlled by use of resin-coated proppant, inorganic fibers, or polymer strips. Each of these technologies has limitations. Resin-coated proppants cannot be used above 374 F and require an activator below 158 F. Thermoplastic strips cannot be used at temperatures above their melting point.

Analysis of the ,fluid, returned to the surface (,flowback fluid,) after hydraulic ,fracturing, indicates that as little as 30 to 45% of the guar-based polymer pumped during the treatment returned from the well during the ,flowback, period. 3 Polymer residues that remain in the fracture significantly contribute to lower proppant-pack permeability, leading to a loss in fracture treatment effectiveness. 1

19/11/2014, · As mentioned above, the clear fracturing flowback fluid is mainly composed of VES which is usually cationic ammonium surfactant and AOS is anionic. When cationic and anionic surfactants are used together, the strong electrostatic attraction leads to the adsorption of more surfactant molecules on the oil/water interface [36] , which results in the appearance of lowest IFT in mixed catanionic systems.

The physical/chemical properties of flowback were categorized in groups to enable the allocation of applicable treatment methods. The analysis revealed that no single technology can meet suitable effluent characteristics, thus two or more treatment systems might be used in series operation. In particular, for flowback containing high salinity concentrations the only treatment options are evaporation or …

Total ,flowback, at Damme 3 from 20 November 2008 to 12 December 2009 amounted to 3,058 m 3 . The proportion of formation water, 69 %, and hydraulic ,fracturing fluid,, 31 %, in ,flowback, were derived from Fig. 3. This shows that only 945 m 3 of the hydraulic ,fracturing fluid, were recovered at this stage.
