Abstract
Various embodiments disclosed relate to cement activator compositions for treatment of subterranean formations. In various embodiments, the present invention provides a method of treating a subterranean formation including placing in the subterranean formation a liquid cement activator composition including water, an alkali sulfate salt, a polyphosphate salt, and a stabilizer polymer.
Claims15
A pre-formulated liquid cement activator composition for a set-delayed pozzolana-lime cement composition, the pre-formulated liquid cement activator composition having fluid loss control properties in addition to liquid cement activation properties and comprising:
- water;
- about 1 wt % to about 15 wt % of an alkali sulfate salt comprising potassium sulfate, lithium sulfate, sodium sulfate, or any combination thereof,
- a polyphosphate salt;
- and
- a stabilizer polymer comprising:
- a repeating group that is an ethylene substituted with a group selected from the group consisting of:
- —C(O)OH, a salt thereof, a substituted or unsubstituted (C1-C20)hydrocarbyl ester thereof,
- —C(O)NR12, wherein at each occurrence R1 is independently selected from the group consisting of a substituted or unsubstituted (C1-C20)hydrocarbyl,
- —CN, and
- any combination thereof,
- wherein at each occurrence the ethylene is independently further substituted or unsubstituted, and
- a repeating group that comprises an anionic group.
