Abstract
A method for providing lower than normal API Class cement slurries for use in oil well cementing is disclosed. Rather than the use of any conventional density extenders for hydraulic cement, such as bentonite, only plain water is added to the selected normal API Class slurry to extend its density. The use of cement retarders, cement accelerators, or friction reducers for these purposes, but not for density extension, is contemplated also.
