Schlumberger - Model RHE-USE - Two-stage Centrifuge System - Brochure

Oil-based fluid treatment process enables reuse of expensive fluids; The RHE-USE system enables operators to reuse invert emulsion drilling fluids over multiple wells without relying on reclamation through high rates of dilution. The process treats oil-based drilling fluid, reducing solids below 1% while drilling. Before the introduction of the RHE-USE system, combating the buildup of ultrafine, low-gravity solids required using dual centrifuges and dilution. With the RHE-USE system, staged centrifugation accompanied by chemically enhanced treatment renders both low-gravity solids (LGS) and drill solids manageable. The system can easily be adjusted to produce relatively ‘dry’ cuttings, reducing drilling wastes.
