Abstract:
A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. The fracturing system includes an isolation sleeve and fracturing spool. The isolation sleeve inserts in an axial bore of the fracturing spool, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A groove in an inner surface of the fracturing spool receives an annular seal for sealing between the isolation sleeve and fracturing spool. Injecting a viscous fluid into the groove energizes the seal, and blocks high pressure fracturing fluid from flowing between the isolation sleeve and fracturing spool.

Claim (Index 5):
The fracturing system of  claim 3 , further comprising:\n an upper seal assembly; an upper groove of the groove; an upper port of the port; an upper seal member of the seal member; a lower seal assembly axially spaced from the upper seal assembly, the lower seal assembly comprising:\n a lower groove in the inner surface of the fracturing spool that circumscribes the spool bore, \n a lower port in the fracturing spool that intersects the lower groove and that is in communication with the fluid supply, and \n a lower seal member in the lower groove; and \n a monitoring port in fluid communication with the spool bore between the upper and lower seal assemblies.
