Abstract

The concept of a modern solids control system for drilling rigs was introduced and experimentally investigated. The system incorporated a conventional solids control arrangement with chemical conditioning and centrifugation. Fundamental trends associated with centrifugal sedimentation of the flocculated suspension with high solids content were formulated based on bench-scale and full-scale tests. They included principles of separation efficiency, mechanisms of sedimentation with high solids content and comparison with other separation and dewatering techniques. The full-scale process study on dewatering a non-dispersed drilling mud revealed the effect of: (1) the field installation, (2) the operational variables, (3) the effect of solids classification prior to dewatering, (4) the effect of dilution and (5) the stability of the dewatering and its sensitivity to chemical dosage. In the series of laboratory tests, flow line samples of five different drilling mud systems were tested for effective chemical treatment and dewaterability. Successful treatment was found for all mud samples. The conceptual design of the modern solids control system was presented and discussed.
