Cement slurry composition and method to cement wellbore casings in salt formations |
摘要 |
A method to cement wellbores in salt formations is provided using a cement slurry composition comprising blast furnace slag, water and salt. The salt improves compressive strength of blast furnace slag based cements. This method is useful in cementing wellbores within salt and potash formations because salt saturated cement slurries can be prepared without the need for expensive additives.
