Cuttings re-injection has become a widely popular drilling waste disposal option, especially in areas such as the North Sea, where it has been employed for over a decade. With this process, drilled solids are injected into deep subsurface fractures, allowing operators to move closer to their zero discharge objectives. Re-injection of drill cut-tings normally involves collection of the waste from solids control equipment on the rig, followed by transportation to a cuttings processing station. Cuttings are slurried in this unit by being milled and sheared in the presence of water, usually seawater. The resulting slurry is then disposed of by pumping it into a dedicated disposal well, or through the open annulus of a previous well into a fracture created at the casing shoe set in a suitable formation.
