ABSTRACT:
Sulfonated or sulfomethylated lignins reacted with phenol-blocking reagents such as ethylene oxide, propylene oxide, butylene oxide or a combination thereof are disclosed as fluid loss agents for cement slurries. The invention permits fluid loss and thickening time characteristics of the cement slurry to be altered either by increasing the molecular weight of the lignin by crosslinking with formaldehyde or epichlorohydrin or by adding additional agents such as sodium sulfite, sodium meta silicate, sodium phosphate and sodium naphthalene sulfonate.
