... are individually compared for flow prediction, and the performance of the correlations is rigorously evaluated on a blind data set that was not originally used for developing the correlations. For both the wellbore and flow loop data sets, a coefficient of determination (or R 2 ) greater than 0.95 with an average...

The effects of the Biot’s coefficient, overburden stress, oil flow rate, fracture’s tip, and proppant porosity arrangements are simulated. The results show that these parameters are essential to minimize formation damage. Model calibration...

The resulting model requires just one empirical coefficient, drag coefficient of the bubble, which depends on the rheology of the fluids and diameter of the pipe. The developed models have been extensively verified...

... with increasing intake GVF. For the same liquid flow coefficient and intake GVF, increasing the intake gas/liquid density ratio increased the DPB of the HAP. The higher intake density ratio enhanced the HAP’s capability to provide positive pressure boost up to an intake GVF just above 98%. It was also observed...

... (1963) proposed a dual-porosity model to be applied to NFRs. Storage ratio and interporosity flow coefficient were introduced to represent NF volume and fluid transfer ability. Later, Kazemi (1969) derived a numerical solution of conventional dual-porosity models considering the transient flow...
