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 .
