Abstract
Methods for servicing subterranean wells are disclosed. Particularly, the use of a fiber-laden fluid to separate and prevent the commingling of two stationary process fluids after placement in the borehole of a subterranean well, or in a tubular body installed in a subterranean well. The fiber-laden fluids prevent the cement plug from descending through drilling fluid to the bottom of the well. It obviates the need for mechanical devices such as packers, or special adjustment of the process fluids' rheological properties.
