Abstract
A wellbore apparatus positionable within a wellbore with a tubular string includes a fracturing assembly and a latch. The fracturing assembly includes a housing comprising a flowbore formed therein and a port, a flow control device configured to move with respect to the housing to selectively allow fluid communication from the flowbore to an exterior of the housing through the port, and a wellbore securing device configured to secure the fracturing assembly within the wellbore. The latch is configured to removably couple the fracturing assembly to the tubular string.
Claims16
A wellbore apparatus positionable within a wellbore with a tubular string, comprising:
- a fracturing assembly comprising:
- a housing comprising a flowbore formed therein and a port;
- a flow control device movable with respect to the housing to selectively allow fluid communication from the flowbore to an exterior of the housing through the port;
- and
- a wellbore securing device engageable with a wall of the wellbore to secure the fracturing assembly within the wellbore;
- and
- a latch configured to removably couple the fracturing assembly to the tubular string, wherein the latch is hydraulically actuatable to removably decouple the fracturing assembly from the tubular string and the latch comprises:
- a latch lug comprising a fracturing assembly latch profile to selectively engage a tubular string latch profile;
- a piston movably positioned within a piston chamber to move the latch lug;
- a sleeve coupled to the piston to move with the piston and engage the latch lug;
- a shear pin to secure the piston within the piston chamber;
- and
- a chamber port to provide fluid communication from the wellbore to the piston chamber through the chamber port to selectively move the piston within the piston chamber.
A method of cleaning out a fracturing assembly within a wellbore drilled from the Earth's surface, the method comprising:
- positioning the fracturing assembly within the wellbore with a tubular string coupled to the fracturing assembly;
- securing the fracturing assembly within the wellbore;
- pumping a fracturing fluid into the tubular string, through the fracturing assembly, and into the wellbore;
- decoupling the tubular string from the fracturing assembly;
- inserting the tubular string into a bore of the fracturing assembly;
- and
- pumping a cleaning fluid from the surface into an annulus formed between an exterior of the tubular string and an interior of the fracturing assembly.
