Abstract
Methods of wellbore cementing are provided. A method of designing a cement composition may include: selecting a target heat of hydration for a target time and temperature; selecting one or more cementitious components and a weight percent for each of the one or more cementitious components such that a sum of a heat of hydration of the one or more cementitious components is less than or equal to the target heat of hydration; preparing the cement composition; and allowing the cement composition to set.
Claims20
A method of designing a cement composition, the method comprising:
- selecting a target heat of hydration for a target time and temperature;
- selecting one or more cementitious components and a weight percent for each of the one or more cementitious components such that a sum of a heat of hydration of the one or more cementitious components is less than or equal to the target heat of hydration;
- preparing the cement composition;
- and
- allowing the cement composition to set.
A method of designing a cement composition, the method comprising:
- selecting a target time and temperature;
- selecting one or more cementitious components and a weight percent of each of the one or more cementitious components;
- calculating a time dependent concentration of each of the one or more cementitious components in the cement composition at the selected temperature;
- calculating heat of hydration at the target time and temperature based on the time dependent concentration of each of the one or more cementitious components;
- preparing the cement composition;
- and
- allowing the cement composition to set.
A system of generating a cement composition comprising:
- a plurality of cementitious components;
- and
- a computer system configured accept input from a user and generate concentrations of the cementitious components for the cement composition, wherein the computer system is configured to generate concentrations of cementitious components based on a target heat of hydration, a target time to reach a heat of hydration, or both.
