A casing annulus remediation hose assembly having a hose with an inlet in selective fluid communication with a fluid supply and an exit connected to a nozzle. On the nozzle is an insertion tip for facilitating insertion and retrieval of the hose assembly in and out of an annulus in a wellhead assembly. The insertion tip has an outer annular flexible housing that is coaxially attached to the nozzle and spherical weighted members arranged in series in the housing. A cable extends coaxially from a downstream end of the nozzle and through each weighted member.

System and method for remediating a wellbore annulus

A system and method for accessing an annulus within a wellhead assembly while the annulus is pressurized. The system includes a tubular body with an attached valve assembly and adapter. The adapter to the wellhead assembly with a sealed annular fitting. The body houses a selectively extendable plunger assembly rotatable by an attached motor. A bit or milling device is provided on the end of the plunger assembly, so that selectively extending the plunger assembly through the valve assembly and adapter contacts the bit against the wellhead assembly. An opening is formed through the wellhead assembly with the rotating bit allowing access to the annulus.

Tool and method for providing access to a wellhead annulus

An adapter for connecting a casing annulus remediation system to a well having a wellhead with standard lateral ports. The adapter has a body with first and second ends. The first end of the adapter body has a substantially planar surface adapted to cover the lateral ports and be in abutting contact with the wellhead when the two are connected to one another. The second end of the adapter body has a planar surface positioned at an angle greater than 0 degrees and up to 90 degrees to the planar surface of the first end. The second end of the adapter is adapted to be connected to a casing annulus remediation system.
