Patent ID: 8403039

Claim:
A method of providing an access path to an annulus in a wellhead assembly comprising: providing an apparatus comprising, a housing, a selectively extendable and selectively rotatablc plunger assembly that comprises a mandrel, a sliding sleeve circumscribing the mandrel, a plenum between the mandrel and the housing, a fluid fitting radially coupled in the housing in fluid communication with the plenum, an axial bore in the mandrel, and bore inlets formed through the mandrel between the plenum and axial bore, and wherein the pressurized fluid flows from the fluid fitting, through the plenum, bore inlets, and axial bore, and flows into the sleeve from the axial bore, and a boring element on an end of the plunger assembly; sealingly connecting an end of the housing to an outer surface of the wellhead assembly; rotating the boring element by rotating the plunger assembly; and boring an opening through the wellhead assembly by extending the plunger assembly in a direction along the housing and rotatingly contacting the wellhead assembly with the boring element to thereby provide pressure communication between the annulus and the housing.
