Abstract
The authors offer a simplified two-zone model to describe fluid flow in steady-state horizontal holes with multi-stage hydraulic fracturing and present the analytical solution in order to calculate sizes of hydrofractures. The new procedure to determine size of multi-stage hydrofractures in horizontal holes is tested using field data on China deposits. The calculation results prove the efficiency of the procedure in the determination of steady-state conditions. The procedure can be used in optimization of hydraulic fracturing.
