Abstract

A procedure and apparatus for cementing and cleaning a reservoir linercomprises installing a reservoir liner using a drill stringwhich extends only as far as the distal end of a cased partof the well, then, using the drill string, displacing cement into the reservoir liner using completion fluid whereby, when the cement is in place in the annulus around the reservoir liner, the reservoir liner is already clean and filled with completion fluid. A ball valveat the top of the reservoir lineris then closed before the cased partof the wellbore is cleaned, to avoid debris entering the reservoir liner.
