BYPASS CROSSOVER SUB SELECTOR FOR MULTI-ZONE FRACTURING PROCESSES |
摘要 |
Fracturing tools for fracturing multiple zones of a wellbore are disclosed. In certain embodiments, the fracturing tools comprise two or more crossover subs coupled together and having a crossover sub window alignment assembly operatively associated with either an isolation sleeve disposed within the bores of the crossover sub-assemblies or with the crossover sub assemblies themselves. Actuation of the crossover sub window alignment assembly opens and closes the windows of each of the crossover sub-assemblies so that different crossover sub- assemblies can be activated to fracture various welbore locations.
