Cuttings re-injection is an in situ method for the disposal of driling cuttings and other drilling wastes into a sub-surface stratum

Drill cuttings are slurrified with water and ground down to a pre-determined partical size. The partical size is achieved by passing through a shaker screen. Slurry of hte correct partical 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 pre-detaimined sub-surface injection zone.
