An automated high speed drill cuttings processing and injection module having a relatively small foot print, capable of operation in zone one hazardous environments, for injecting drill cuttings into an earth formation, capable of handling high drilling rate cuttings surges. The process including conveying systems, holding and slurry tanks, circulating pumps, high speed grinding mill, high pressure injection pump, fragmentation system and automation system for controlling electrically driven injection pump having automatic speed control regulation with torque and horsepower limiting features. Thereby allowing high-speed injection without plugging the formation while still allowing for high-pressure formation fracturing when necessary. The processing system further insures cuttings slurry homogenization and entrained particle size to less than 100 micron for both hard and soft particles. The system reduces installation cost dramatically. An onboard computer system further provides continuous automatic control, measures and records continually the dry weight of cuttings removed from the hole and controls, slurry density and viscosity, as well monitoring and maintaining injection pressure to within established high and low pressure parameters.
