Abstract: A cement composition, comprises a mixture of a blend of materials including cement and/or micro cement, calcium carbonate, organic fibres, and inorganic fibres; and water; wherein the composition forms a cement that is at least partially soluble in acid and/or water. A method of treating a well, comprises pumping the composition into the well, allowing the cement to set, and treating the set cement so that it is partially to completely dissolved. In case of partial dissolution the residue in time is degradable. The inorganic fiber can be used in the traditional cementing in all stages of the well construction to defeat partial losses and improve the set properties of the final set cement.
