Abstract
A well cleanout system for removing accumulations of solid particles in a gravel pack screen or liner and in the vicinity of a casing or liner hanger includes a tubular extension member which may be lowered into the production fluid tubing string and secured to a nipple at the lower end of the tubing string. Coiled tubing with a nozzle arrangement on the distal end thereof is extended through the tubular extension member and into the wellbore for jetting a cleanout fluid into the wellbore to entrain solids in a fluid stream which is pumped to the surface through the production tubing. The coiled tubing, nozzle and extesnion member may be retrieved by unlocking the extension member and pulling the coiled tubing out of the wellbore.
