... tests were conducted at manufacturing facilities for determining the characteristics of the entry holes in pipe produced by shaped explosive charges using various system configurations and the robustness of various gun orientation devices. Promising perforating systems were then used in wellbores...

.... None of these commercially available models consider proppant momentum and interactions of particles with other particles, fluids, and fracture walls. In addition, turbulent flow near wellbore is completely ignored in these models. Slot tests used for proppant transport in laboratory studies are too...

In our paper, we present the results of this simple model and compare it with more complex fracture modeling efforts and fracture diagnostic results in a few major US...

... It is important to consider the amount of proppant settling in the wellbore because the settled proppant does not end up in fractures and ultimately does not play a role in keeping the fractures open for production. Moreover, it also affects the wellbore area for conveyance of fracturing fluids...

... fluid columns may be present in the vertical section of the wellbore. This significantly changes the FDI pressure response compared to the case where the wellbore is completely full of water. A FDI analysis modeling technique has been developed when the observation wellbore has a gas, oil and water...

.... The pressure behavior has been analyzed by a patented method, Sealed Wellbore Pressure Monitoring (SWPM), and it is an effective means to detect frac hits. To extend the understanding of this pressure behavior for wider applications, we proposed a methodology of simulating the casing response and corresponding...

These treatments superficially seem mundane. However, they successfully demonstrated the viability of hydraulic fracture creation in a cased well...

... and fracture geometry. The impact of fracture vs wellbore orientation and overflush were also modelled. This is the first time such a workflow has been applied for a conventional yet naturally fractured reservoir. The proposed modelling workflow allows for optimization and robust fracturing design...
