Provided is a glass bead suspension. The glass bead suspension comprises water, a synthetic hectorite having an empirical formula of SiMgLiHONa, and glass beads.

Synthetic hectorite in glass bead suspensions

Provided is a method for cementing. The method comprises providing a glass bead suspension comprising water, a synthetic hectorite, and glass beads. The method further comprises mixing the glass bead suspension with components comprising cement and additional water to form a cement composition. The method additionally comprises allowing the cement composition to set.

Engineering bead slurries may be useful in producing lightweight cement slurries for use in subterranean cementing operations. For example, a method may include engineering a bead slurry to have a shelf-life of about 1 month or greater by performing at least one of (1) calculating the shelf-life for the bead slurry and (2) calculating a minimum yield point required to prevent a lightweight bead of the bead slurry from floating or settling in the bead slurry; wherein the bead slurry comprises a gelled base fluid and a plurality of lightweight beads having a specific gravity of about 0.8 or less; producing the bead slurry; mixing the bead slurry and a cement slurry to yield a lightweight cement slurry; introducing the lightweight cement slurry into a wellbore penetrating a subterranean formation; and allowing the lightweight cement slurry to set therein.

A system for measuring one or more physical properties of cementitious material is operable to cure a slurry of cementitious material under desired conditions of temperature and pressure. Particularly, the system may be operable to cure the slurry under a temperature and pressure expected to be experienced downhole. The system may also be used to determine properties of the cured cementitious material, such as maximum yield strength and shear bond strength at the desired temperature and pressure. The desired conditions of temperature and pressure may be applied both during curing and testing of the cementitious material.

In situ testing of mechanical properties of cementitious materials

A variety of methods and compositions, including, in one embodiment, a method of treating a subterranean formation comprising introducing a treatment fluid into a well bore, wherein the treatment fluid comprises a particulate elastomer having a specific gravity of at least about 1.6. Another method of treating a subterranean formation comprises introducing a treatment fluid into a well bore, wherein the treatment fluid comprises a particulate elastomer having a specific gravity of at least about 1.05, wherein the particulate elastomer comprises a halogenated thermoplastic.
