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.

Figure 6 shows the viscosity reduction effect of the ,residual, chlorine (1 × 10 3 mg/L) and Fe/Ni catalyst on ,fracturing flowback,. After adding catalyst, the viscosity reduction rate was increased from 34.10% to 63.16% for sample A (from 66.16% to 85.91% for sample B), which means the catalyst could improve the oxidation reaction of electrolytic brine significantly.

The Effect of Fracturing Fluid Saturation on Natural Gas ...

Fracturing fluid, trapped in the micro-nano induced cracks is difficult to ,flowback, due to the strong capillary force, but under the capillary force, the liquid can move from induced cracks to small pores, which can greatly increase the main ,gas, flow channel, and thus after well shut-in for a time, shale ,gas, can flow out of the formation.

The Effect of Temperature on Flowback Data Analysis in ...

After the fracturing and shut-in periods, shale gas wells go through a process of flowback to return the injected fracturing water before production. Recent studies suggested that the rate and pressure data recorded during flowback can provide a very early opportunity to characterize fracture network after the fracturing treatment [ 31, 32, 33 ].
