摘要： Methods and apparatus of pressure activated completion tools for hydraulic fracturing and related processes are provided. In some embodiments, the hydraulic fracturing apparatuses for accessing a subterranean formations can include a tubular body to be fluidly connected in-line with a completion string, the tubular body having at least one burst port configured to receive burst inserts (burst plugs), and a movable inner sleeve that can slide along the inside of the tubular body when exposed to hydraulic pressure from a first position to a second position. The tubular body can also have flow-port(s) that are blocked when the movable inner sleeve is in the first position and opened when the movable inner sleeve slides to the second position.

摘要： A set of pressure activated tools that could be used in a well bore to allow for hydraulic fracturing completions are provided. Methods, apparatuses and assemblies are described herein for perforating (also known as hydraulically fracturing or stimulating) subterranean formations. In some embodiments, an insert is provided having a body for sealing engagement with a port in a tubular member. The insert body can include a fold-over ledge and a membrane having a first mode wherein the membrane prevents fluid passage through the body and a second mode wherein the membrane partially disengages from the body upon treatment fluid reaching a threshold pressure and folds over the fold-over ledge in a bottle-cap opening manner to contribute to the fracture of the formation by the pressurized treatment fluid exiting the port.
