Cuttings Re-Injection (CRI) is an in situ method for the disposal of drill
cuttings and other drilling wastes into a sub-surface stratum.
Drill cuttings are slurrifi ed with water (fresh or sea water) and ground
down to a pre-determined particle size. The particle size is achieved by
passing through a shaker screen. Slurry of the correct particle size and
physical properties is injected via a pump, which is typically of a triplex
design, into the well head at a given pressure and down into the predetermined
sub-surface injection zone. Oversize particles from the shaker
are re-circulated for further grinding.
