Halliburton provides different classifications of cement from cement manufacturers based on downhole conditions of a specific area. The American Petroleum Institute sets forth specifications for the manufacture of cement in API Specification 10A, Twenty-first Edition, September 1, 1991.
The base cement is usually modified with blended additives or liquid additives so the properties of the cement slurry are suitable for the various types of formations encountered in a well.
Portland cement can be extended with pozzolanic material to yield an economical slurry with premium properties. Combining pozzolanic material with cement produces a reaction that can improve the properties and compressive strength of the set cement sheath.
Acid Soluble Cement
Provides a temporary cure for lost circulation across production zones which can be removed with HCl, resulting in less potential formation damage.
Micro Fly Ash™ Cement
A small-particle fly ash developed as a supplement for Micro Matrix cement slurries for temperatures below 110°F (43.3°C)
Thermatek® Fluids
An acid-soluble, non-invasive system typically used for severe lost circulation, wellbore construction, temporary plugs, or setting annular plugs in casing or open hole.
