ABSTRACT:
The present invention provides methods of cementing a well with a cementing composition utilizing a portion of the drilling fluid used to drill the well as a component in the cementing composition. The methods basically comprise forming a set-activated cementing composition comprised of water, silica fume, a dispersing agent, a set-activator, a set delaying additive and a portion of the drilling fluid, introducing the resulting set-activated cementing composition into the well and permitting the cementing composition to set into a hard mass therein.
