... expected. The flow regimes of Child well can be divided into: wellbore storage & skin effects, fracture bilinear flow, "fluid supply", formation linear flow, pseudo-boundary dominated flow, "well interferences", pseudo-radial flow, and boundary-dominated flow. The stage of "well interferences" occurs...

... This subsection first analyzes the typical curves and divides the typical flow regimes. Then taking pattern Ⅲ as example, we conduct sensitivity analysis on crucial parameters (i.e., cave storage coefficient, fracture length, matrix and vug storativity, vug inter-porosity flow coefficient and gravity coefficient...

... to remove the noise and water hammering effects. The PTA diagnostic plots were used to define the flow regime and the data were matched with an analytical model to calculate producing surface area. Tensile and shear fractures are both created during the injection of frac fluids. Shear fractures are caused...

... a practical and operational standpoint of view is to maintain a flow velocity that does not allow sand to settle down. It is essential to understand the flow behavior in a pipeline to determine this velocity as it depends on multiphase flow regimes. The different phases in various flow regimes may travel...

In the case of slug flow, the liquid phase entrains some gas bubbles inside but, there is no gas bubble entrained inside the liquid phase for elongated bubble flow. When the fluids reach the vertical section of the well the flow regimes...

In general, the effect of natural fractures seems to be more evident than that of frac-hits. Blasingame plots could...
