摘要： The present disclosure is generally directed to systems that are used for reclaiming components of wellbore cuttings material. In one illustrative embodiment, a system is disclosed that includes, among other things, a dryer that is adapted to receive a drill cuttings mixture that includes drilling fluid and cuttings material, the dryer being further adapted to treat the drill cuttings mixture by drying the cuttings material below a preselected moisture content level. The system also includes a moisture sensor that is adapted to sense a moisture content of the cuttings material after it is dried by the dryer, and a cuttings reinjection system that is adapted to reinject the dried cuttings material into a well bore. Additionally, the system includes a conveyor system that is adapted to convey the dried cuttings material to the cuttings reinjection system, wherein the conveyor system includes, among other things, a positive pressure pneumatic conveying apparatus.
