1/10/2020, · According to Mark-Houwink's empirical ,formula, (He et al., 2007; Guo; He., 2012), it could be seen that the ,viscosity, of the ,fracturing fluid, is exponentially related to the molecular weight. Therefore the gel breaking performance of the ,fracturing fluid, cannot be fully characterized by ,viscosity,.

1/3/2021, · ,Fracturing fluid flowback, can be considered in two stages. The ,flowback, mechanism for each stage is different. The two stages can be distinguished by the critical T2 relaxation time determined by the low-field NMR, as described in Fig. 12. At first, a cumulative T2 value for the saturated sample should be calculated.
