ABSTRACT:
A cementitious slurry is prepared from drilling fluid, blast furnace slag and an emulsion comprising an oil external phase and an aqueous internal phase having therein a additive for said cementitious slurry. In a preferred embodiment the additive is an accelerator for the blast furnace slag such as sodium hydroxide. This allows mixing the additive with the drilling fluid and blast furnace slag without immediate contact between the additive and the other ingredients. After the cementitious slurry has been mixed and pumped into position in a wellbore, the emulsion breaks and the additives are released.
