Cementing Tables

Cementing products and additives

The following reference section lists cementing products and additives available from several majorsuppliers. Products, which are grouped into functional categories, may be unique to a company, andmany are protected by patent rights or other legal means. They may be chemically similar, but notidentical, and provide comparable performance in cement slurry formulations. Exact equivalency is notimplied.

Where applicable, products are subdivided into groups having similar performance within each functional category. Performance groupshave been subdivided to reflect significant differences in chemical nature of additives and emphasize uniqueness within each company'sproduct line. What cannot be different cements, or performance variations resulting from different sources of the same material aroundthe world. Materials should be tested according to accepted procedures to ensure that performance requirements are met. Also, usersare cautioned that it is generally not possible or prudent to make direct "translations" of cement formulations between service companiesbased solely on additive descriptions.

Products are grouped in 15 functional categories:

Basic cements Retarders

Accelerators and salts Anti-gas migration agents

Extenders and density-reducing additives Anti-foam and defoaming agents

Free water control and solids suspending agents Density increasing or weighting agents

Dispersants Additives and mixtures to reduce or prevent lost circulation

Bond improving and expanding additives Spacers and chemical washes or preflushes

Fluid-loss control additives Specialty cement blends

Silica to reduce or prevent high temperature strength retrogression

Temperature has a significant effect on many cementing additives and is the single most important variable in affecting cementhydration. This is particularly true for retarders, but also applies to fluid loss control additives, anti-gas migration, expanding and otheragents. Salt tolerance is particularly important in fluid loss control additive selection. Where applicable, this reference includestemperature range groupings, salt tolerance and other variables critical to additive performance. Temperature and salt tolerance arebroad groupings and actual performance may vary somewhat in formulations and well conditions.

Important note. Fluid loss control additives are listed according to maximum temperature and salt tolerance for that product. Forexample, if an additive is shown to be effective up to about 250ºF in the presence over 18% salt (by weight of mix water), it is verylikely that this product is also effective at higher temperatures with lower salt concentrations. There are several examples of this in thetable.

Finally, if a company does not have an equivalent to a competitor's product listing, it does not mean that the company cannot come upwith a cement formulation that achieves similar performance. Our recommendation is to call the company, describe the application orproblem and let them work on a solution. Even though additive technology has advanced, it is still best applied with a measure ofexperience.
