Chemical activation for cement setting |
| abstract |
A method of accelerating the compressive strength development and setting time of a cement slurry during a cementing operation for a wellbore comprising: preparing a cement slurry comprising a hydraulic cement and water on the surface; nplacing the cement slurry in the wellbore; nadding an activator to the cement slurry in the wellbore; and nallowing the cement composition to set; n nwherein the activator acts as a set accelerating agent and a compressive strength enhancing additive. |
