Title: Apparatus and method for analyzing well fluid sag

Patent ·
OSTI ID:5345582

This patent describes a method of analyzing sag phenomena in well fluids. It comprises: mounting an elongate container containing a sample of a fluid to be tested on a force responsive device which provides a measurable, variable indication of the center of mass of the container, at an angle with respect to vertical; holding the angle generally constant, but for small movements corresponding to changes in the center of mass of the container due to sagging of the contents of the sample, for a period of time sufficient for such sagging to occur, and measuring the indication.
