Fracturing-Fluid Flowback Simulation with Consideration of ...

Fracturing-fluid flowback is simulated with the use of a developed simulator. A hydraulically fractured horizontal well with a 1200 m horizontal wellbore and 15 fracturing stages situated in the center of a shale reservoir (1500 m × 560 m × 40 m) is considered. The initial reservoir pressure is 25 MPa.
