COMPOSITIONS AND METHODS FOR COMPLETING SUBTERRANEAN WELLS
Hydroxyethylcellulose (HEG) may be used to provide fluid-loss control in well-cement slurries HECs that have a molecular weight above 600,000, a degree of substitution higher than 1.9 and a molar substitution above 2.0 are particularly useful in that they not only provide fluid-loss control, but also may be used as a cement extender. Furthermore, the retardation effect may be reduced.
