As water content in the ,fracturing fluid, for shale gas reservoirs is generally higher than 90% , the ,flowback, ratio is closely related to existing state of water in shale. Three shale outcrop samples were put into a container with 5 mm water respectively, after 24 h, the capillary imbibition effect observed is …

Oilfield ,fracturing flow-back fluid, was treated by Cl O2 catalytic oxidation process. Under the conditions of Cl O2 dosage 15m L·L- 1, concentration of 20%, oxidation reaction time 20 min and initial wastewater COD was 1883.7mg·L- 1, the COD removal rate was 78.1%. In order to achieve the ideal treatment effect, a certain amount of the composite metal catalyst was added into the ,flow-back, ...

Abstract Shale gas reservoirs generally need to be fractured massively to reach the industrial production, however, the ,flowback, ratio of fractured shale gas wells is low. In view of this issue, the effects of natural fracture spacing, fracture conductivity, ,fracturing, scale, pressure coefficient and shut-in time on the ,flowback, ratio were examined by means of numerical simulation and ...
