Abstract: 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.

Abstract: 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.

Abstract: A system and method of forming a mixture from two elements according to which the elements are introduced into a vessel and mixed in the vessel before being discharged from the vessel. The flow rate of one of the elements is controlled to maintain a constant level of the mixture in the vessel and the flow rate of the other element is controlled to maintain a predetermined ratio of the flow rate of the latter element and the discharge flow rate.
