Abstract

A system for slurrifying drill cuttings including a cuttings dryer, a pump, and a transfer line fluidly connecting the cuttings dryer and the pump, the transfer line having a fluid inlet for receiving a fluid. Furthermore, the system for slurrifying drill cuttings including a storage vessel fluidly connected to the pump for storing a slurry. Additionally, a method for slurrifying drill cuttings including drying drill cuttings in a cuttings drying to produce dry cuttings and combining a fluid with the dry cuttings to produce a slurry. Furthermore, the method includes mixing the slurry and the dry cuttings in a mixing pump and transferring the slurry to a storage vessel.
