Abstract:
Well cementing compositions comprise water, an inorganic cement and flexible particles having an average density higher than 1.5 g/cm3. The flexible particles may be elastomers. The flexible particles and cement particles may be present in a trimodal particle size distribution. The compositions may be placed in subterranean wells in the context of primary or remedial cementing.
