Abstract
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.
