Mud displacement with cement slurries

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1973
Mud displacement efficiency was studied under conditions simulating theborehole environment at 8,000 feet. Major findings were that the buoyantdriving force resulting from the density difference between cement and mud hasless effect on mud displacement than expected under such conditions and thatpipe motion with scratchers substantially improves mud ...
