Paper Number: ARMA-2021-1267
... ABSTRACT: Since the flow back process is crucial to post-frac production behavior for shale gas wells in shale gas play, considering setting the fractured well as an injecting well, a numerical model was established to simulate the flow back dynamic by software Eclipse. Then a workflow was put...

.... The extended leak-off test (XLOT)/ pump-in and flow-back test (PIFB) have been the industry-standard for stress determination during drilling for some time, where drilling mud is injected to create a small fracture in an vertical open-hole below a newly cemented casing. This is followed by a shut-in phase...

... Abstract After hydraulic fracturing, the flow-back of fracturing fluid is necessary before the gas production starts. A review of fracture treatments indicates that the incomplete return of treating fluids is a reason for poor gas production. It is believed that the water blockage in tight sand...
