oilfield drilling mud decanting centrifuge manufacture

Economic justification for using decanter centrifuge s with weighted muds traditionally has been based on the savings realized by recycling the larger barite particles. However, this is not the most important benefit. When centrifuges are not used, the concentration of fines tends to be higher and the mud quality lower. This often leads to an increase in costly hole problems, which can be a much larger economic factor than the savings from the barite recovery process. In actuality, the finer barite particles are discarded with the overflow, and this can be a significant part of the total barite present. Using the quick and dirty barite recovery concept to justify centrifuge rental is a simple, though flawed, calculation that has impeded the understanding of the real benefits of using centr
