ABSTRACT:
An improved method of monitoring the setting of a settable liquid-containing material is provided. The compressibility of one or more fluids including the settable material is monitored at periodic intervals during the setting process. As the material sets, its compressibility is lowered, and the overall fluid compressibility is reduced. When the settable material hardens completely, its compressibility approaches zero and the overall fluid compressibility levels off. The method is especially useful for monitoring the setting of cement in the annulus of a well bore, and for determining when the cement is fully set.
