Abstract
A drilling fluid manager creates a multi-dimensional drilling fluid additive model and interpolates changes in a drilling fluid based on a combination of additives. The interpolations are inverted to determine the amount of additives based on measurements of drilling fluid properties. As fluid is returned to the surface, drilling fluid parameters are measured. A difference between the measured fluid parameters and setpoint fluid properties and the inverted interpolations are used to determine the amounts of each additive.
