Cement slurries for diviated wells

What is disclosed is a method of cementing in which a plurality of cement slurries are employed in a well penetrating subterranean formations and having a deviated section of more than 55 degrees angle of inclination, the improvement comprising emplacing at a desired depth in the well a plurality of cement slurries, at least one of which is less dense than the drilling fluid employed to drill the well; and allowing the cement to set up in the well and to bond in situ and provide the zonal isolation and good bonding of equipment in the wellbore. A specific example given in which one of the cements had a density of less than 12 pounds per gallon and one of the cement slurries has a density of greater than 12 pounds per gallon.
