WELL CEMENTING COMPOSITIONS AND METHODS
Cement slurry compositions comprising water, an inorganic cement and additive comprising nanocrystalline cellulose, microcrystalline cellulose, cellulose fibrils, or bacterial nanocellulose or combinations thereof have reduced fluid loss values. Such compositions may be prepared and placed in subterranean wells. The compositions are suitable for use during primary cementing or remedial cementing operations.
