Title: Cementing wells with crack and shatter resistant cement

Abstract: Improved cement compositions and methods of cementing subterranean zones penetrated by well bores are provided. In accordance with the methods, a crack and shatter resistant cement composition is introduced into a subterranean zone by way of the well bore penetrating it comprised of a hydraulic cement, sufficient hydrophilic fibers to make the cement composition crack and shatter resistant upon setting and sufficient water to form a pumpable slurry. Thereafter, the cement composition is allowed to set in the subterranean zone.
