The basic function of the Shale Shaker is to provide primary solids removal from both oil based mud (OBM) and water based mud (WBM) during drilling operations.
The rotating separator process is based on a different principle than the shale shaker process. The mud line flow is fed into the slowly rotating separator. The drilling fluid contaminated with drilled cuttings is fed into the centre of a screen coated drum as shown schematically in Fig. 1. The outside of the drum is connected to an under-pressurised ventilation system.
As a result of differences in the design of shale shakers and front hoods/enclosures, it was difficult to test all shakers within the exact same parameters. It was determined that each shaker had to be tested as dictated by the differences in design of each unit (Fig. 10).
Drilling operations are highly dependent upon reliable shale shaker to perform efficient drilling operations. Suitable drilling fluid quality, efficient solids removal and low waste production, as well as health, safety and environment (HSE), especially of working environment (WE) in the shaker room, are all respects relevant for selection and skills operation of shale shaker in the oil industry.
