A drill cuttings injection system for a well with a wellhead housing and a casing hanger supported in the wellhead housing. The wellhead has an axial flow port with an upper end in communication with an outer surface of the housing and a lower end in communication with an inner surface of the housing. An injection ring is positioned on the wellhead housing and has an external port. The injection ring defines an annular gallery in communication with the upper end of the axial flow port. A cuttings injector is adapted to land on the injection ring and has a hydraulic passageway sealable to the external port through which drill cuttings can be pumped into the well.

1. In a system for injecting drill cuttings into a well, wherein the well has a wellhead housing and a casing hanger connected to a casing and sealed in the wellhead housing by a packoff, the system comprising: at least one flow passage through a sidewall of the wellhead housing in communication with an annulus surrounding the casing; an injection ring having an inner surface in contact with an exterior surface of the wellhead housing, the injection ring having an external port and defining an internal annular gallery in communication with the flow passage; and a cuttings injector coupled to the injection ring that has a passageway sealable to the external port through which the drill cuttings can be pumped for flowing through the gallery, flow passage, and into the annulus.
