Abstract: The invention relates to a multistage high pressure fracturing system and tubular hydraulic valve (THV) system for connection to a completion string to enable isolation of a zone of interest within a well. In particular, the system enables access to a downhole formation for fracturing the zone of interest and for hydrocarbon production. The system generally includes a plug counting system, a plug capture system and a valve system wherein dropping a series of plugs down the completion string enables successive capture of individual plugs within individual THVs for subsequent fracturing operations.

Abstract: A system and method for fracturing multiple zones in a hydrocarbon well is provided. The system comprises a series of multistage fracturing devices (MFD's) that are connected along a casing or completion tubing string and have ports that can be opened to allow fracturing of the formation adjacent the MFD. The ports in each MFD are triggered to open by a dart having a specific geometry that is pumped downhole and caught by a catching mechanism that comprises levers or “fingers” in the MFD. Upon catching of the dart, the section downhole of the dart can be sealed off and the ports located uphole of the dart can be opened to allow fracturing operations to occur.
