Title: Method for monitoring drilling mud properties

Abstract: A method for monitoring drilling mud properties, the drilling mud being transported through a well drilling system and stored in a mud pit includes directing the flow of drilling mud in the well drilling system from the mud pit to a sampling unit. A sample of the drilling mud from the mud pit is obtained. At least one mud property of the sampled drilling mud is sensed automatically and in real time to obtain a condition value. If the condition value is within a set point range for the mud property the drilling mud is returned to the mud pit. The drilling mud is directed to a centrifuge for adjustment of the mud property if the condition value is outside the set point range. The drilling mud from the centrifuge is returned to the mud pit after the mud property has been adjusted.
