Compositions and methods for maintaining zonal isolation in a subterranean well |
| abstract |
Well cementing compositions comprise water, an inorganic cement and flexible particles having an average density higher than 1.5 g/cm 3 . 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. |
