Abstract
An apparatus and a method are described for measuring the sag properties of a drilling fluid by using a conically or frustro-conically shaped inner body and an outer body having an opening with contours closely matching those of inner body such that in conjunction inner and outer body are separated by a narrow gap defining a conically or frustro-conically volume with a vertex; a motor drive for rotating the inner body with respect to the outer body; and a sampling access to determine the density of said drilling fluid within a localized part of said volume, wherein said sampling is permanently located in vicinity on said vertex.
