Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A casing annulus remediation hose assembly comprising: a hose with an exit and an inlet in selective fluid communication with a fluid supply; a nozzle having a check valve that is selectively openable in response to pressure in the hose; and an insertion tip having an outer annular flexible housing that has an upper end coaxially attached to the nozzle and weighted members flexibly connected to one another that are in the housing and that are axially spa…
