Claim:
A method of displacing fluids in an annulus between casing strings of an active oil or gas well, the well having a wellhead with an outlet bore extending perpendicular to a longitudinal axis of the wellhead, the method comprising: providing a hose for injection into said annulus through the outlet bore of the wellhead, wherein an intersection of said outlet bore and said wellhead has a corner with a first radius which might damage said hose; inserting a turndown into said outlet bore from an outer end of said outlet bore and positioning an inner end of said turndown in said annulus, the turndown overlapping said corner with a surface with a second radius larger than said first radius; inserting said hose through said outlet bore, along said second radius of said turndown, and down into said annulus; and pumping fluid through said hose into said annulus to displace at least a portion of said fluids in said annulus out of said annulus.
