VCD Application VCD Application is Driven by Three Key Objectives: Drilling Fluid Waste Solid Waste Solid Reclamation Reduction Declassification VCD’s recover OBM and By reclaiming drilling Depending on the rig site WBM from drill cuttings fluid from the cuttings, (offshore vs. onshore) or discharged from the flow the overall volume (or even on the region in line shakers. Shakers weight) of the cuttings is which the drilling activity can discharge cuttings lowered, therefore is occurring, the that are up to 25% by lowering transport and reduction of the fluid weight “wet”. When disposal costs by the content can lower the unrecovered, this lost same percentage of fluid hazard classification of fluid will cost the rig recovery, generating the waste solids. thousands per day. further savings. The application of a VCD is driven by return on investment generated from the above three goals.
VCD Application VCD’s as a Waste Management Device. Barite VCD’s are not a solids control system, they are strictly designed for waste management and fluid recovery.

Shaker Discharge Liquid Content (% Weight) A 2/3 reduction in drilling fluid loss can be achieved depending on the formation being drilled.
