Abstract:
A method and apparatus according to which at least part of a wellhead is fluidically isolated from excessive pressures, temperatures, and/or flow rates during a wellbore operation using an isolation head, the isolation head including an isolation spool and an isolation sleeve.

Claim (Index 1):
A system, comprising:\n a wellhead that serves as a surface termination of a wellbore that traverses a subterranean formation, the wellhead including a lower packoff surface; an isolation head, comprising:\n an isolation spool operably coupled to the wellhead; and \n an isolation sleeve including upper and lower packoff assemblies; \n and an upper packoff surface; wherein the isolation sleeve is movable relative to the isolation spool to sealingly engage the upper and lower packoff assemblies with the upper and lower packoff surfaces, respectively; wherein, when the upper and lower packoff assemblies are sealingly engaged with the upper and lower packoff surfaces, respectively, the isolation sleeve isolates at least a portion of the wellhead from a fluid flowing through the isolation head; and wherein either:\n the upper packoff surface is part the isolation spool; or \n the upper packoff surface is part of a frac tree operably coupled to the isolation spool opposite the wellhead.
