Massive salt sequences have posed numerous cementing problems over the years. Many additives, designed for use in fresh water based slurries, display poor performance when placed in very saline environments. Other additives, designed primarily for use in very saline environments, have less than optimum performance and exhibit detrimental side effects to other slurry performance properties.

This paper discusses the problems posed when cementing through these salt sequences, current practices to deal with the problems, and describes the benefits of new materials which provide superior performance in high-salt slurries. Field case histories are included from the Williston Basin to illustrate field utility.
