According to an embodiment, a method of cementing in a subterranean formation comprises: introducing a cement composition into the subterranean formation, wherein the cement composition comprises: cement; water; and calcium silicate hydrate (C-S-H) seeds, wherein a test cement composition consisting essentially of: the cement; the water; and the C-S-H seeds, and in the same proportions as in the cement composition, develops a compressive strength of at least 1,200 psi (8.3 MPa) when tested at 24 hours, a temperature of 60&#xb0; F. (15.6&#xb0; C.), and a pressure of 3,000 psi (20.7 MPa); and allowing the cement composition to set. According to another embodiment, the C-S-H seeds are mesoscopic particles, nanoparticles, or combinations thereof, and wherein the C-S-H seeds are in a concentration in the range of about 1% to about 5% by weight of the cement.

A well treatment composition comprises a surfactant comprising a substituted ethoxylated phenol having at least one substituent, 1 to 14 moles of ethylene oxide, and the substituent being an alkyl, alkene, or alkyne with a carbon chain length in the range of 4 to 25, wherein the substituted ethoxylated phenol is selected from the group consisting of: ortho-, para-, or meta-substituted ethoxylated phenol; cardanol ethoxylate; derivatives thereof; and combinations of any of the foregoing. Preferably, the surfactant comprises cardanol ethoxylate, a substituted cardanol ethoxylate, and derivatives thereof. A method of cementing in a subterranean formation comprises: introducing a cement composition into the subterranean formation, wherein the cement composition comprises: (A) cement; (B) water; and (C) the surfactant; and allowing the cement composition to set.
