摘要: 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. Embodiments relate to the prevention of a 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.

摘要: The problem of fibre or particle settling in well cement slurries is addressed by providing a fluid containing two fibre components of differing properties. Such a well treatment fluid, comprising a base fluid; a first fibre component that it substantially more dense than the base fluid; and a second fibre component that has a density close to that of the base fluid and is relatively flexible.
