Tailoring for temperature sensitivity of thickening time of cement slurry
A method of designing a cement slurry comprising: (a) selecting at least a cement and concentration thereof, a water and concentration thereof, and one or more chemical additives concentration thereof such that a cement slurry formed from the cement, one or more chemical additives, and the water meet a density requirement; (b) calculating a thickening time of the cement slurry at the wellbore temperature using a thickening time model; (c) comparing the thickening time of the cement slurry to a thickening time requirement and performing steps (a)-(c) if the thickening time of the cement slurry does not meet or exceed the thickening time requirement, wherein the step of selecting comprises selecting different concentrations and/or different chemical identities for the cement and/or one or the more chemical additives than previously selected, or performing step (d) if the thickening time of the cement slurry meets or exceeds the thickening time requirement; and (d) preparing the cement slurry.
