... and fracture reorientation reveals the advantages of refracturing using new over old perforations. The operation restores fracture conductivity and increases the fracture network as well as the drainage areas leading to an economic operation. The model improves the characterization of the Stimulated Reservoir...

... Abstract When hydraulically fracturing a horizontal wellbore with multiple perforation clusters, the fluid being pumped into the reservoir will preferentially take the path of least resistance. Perforations that are located in the lowest stressed rocks will take a larger amount of fluid...

... Abstract Multistage hydraulic fracturing has become the key technology for completion of horizontal and vertical wells. The perf and plug method is the most commonly used staging method. During each stage, multiple perforation clusters are used, attempting to create a separate transverse...

... In this operator’s experience, one of the main concerns in horizontal wells is fiber damage during fraccing operations. It should be noted that this operator has no recorded failures due to fraccing in vertical wells to date. Similar to the perforation failures, a fiber failure during a frac stage results in a loss...
