Low-portland extended life slurries for use in oilwell cementing |
| abstract |
A method of preparing a cement may include: defining one or more engineering parameters of a proposed cement slurry; selecting at least: a cement and mass fraction thereof and at least one supplementary cementitious material and mass fraction thereof; a retarder and mass fraction thereof; and a water and mass fraction thereof, such that a slurry formed from the cement, the at least one supplementary cementitious material, the retarder, and the water meets at least one of the one or more engineering parameters and has a property of being capable of remaining in a pumpable fluid state for a period of about 1 day or greater at a temperature of about 80 °F in quiescent storage; and preparing the slurry. |
