  • Spacer fluids for well cementing operations
    Publication number: 20030153646
    Abstract: A spacing fluid or “spacer”, of the type comprising a fluid and particles, notably particles of loading agent, as well as possibly normal additives, such as a viscosity-increasing polymer, for separating a cement slurry from borehole fluids during a well cementing operation, characterised in that the spacing fluid has a density close that of the drilling fluid or mud and a viscosity close to that of water, by virtue of the adaptation of the size of the particles to a value less than 5 microns, particularly around 2 to 3 microns or around 0.2 to 0.3 microns, such as by the use of magnesium oxide or rutile.
