Abstract:
1. An apparatus for remediating a casing annulus of a well, the well having a wellhead with a longitudinal axis, a lateral port which is substantially perpendicular to the axis, at least one string of casing supported in the wellhead and extending past the lateral port into the well, defining an annulus, the apparatus comprising: an adapter body having first and second ends, the first end having a planar surface adapted to be in abutting contact with and connected to the wellhead, thereby covering the lateral port, the second end having a planar surface positioned at an angle greater than 0 degrees and up to 90 degrees relative to the first planar surface; a passage extending from the first end to the second end of the adapter body; and a casing annulus remediation system connected to the second end of the adapter body, the casing annulus remediation system comprising a flexible hose and a hose driver that pushes the hose through the passage and into the casing annulus through an access port extending through a portion of the wellhead adjacent the first end of the adapter body and aligned with the passage.
