Abstract

Methods of the present disclosure relate to quantitative assessments of the risk of damage to cement sheaths due to cyclic loads. A method comprises selecting cement compositions; performing wellbore integrity analyses using models for cement sheaths, each cement sheath comprising a selected cement composition; and determining a number of cycles to failure for each cement sheath.

First claim

What is claimed is:

1 . A method comprising:
selecting cement compositions; performing wellbore integrity analyses using models for cement sheaths, each cement sheath comprising a selected cement composition; and determining a number of cycles to failure for each cement sheath.

2 . The method of claim 1 , further comprising producing at least one selected cement composition based on the number of cycles to failure.

3 . The method of claim 1 , further comprising receiving pressure, temperature, and time data for each cement sheath.

4 . The method of claim 1 , further comprising determining deviatoric stress levels from the wellbore integrity analyses.

5 . The method of claim 4 , further comprising receiving the deviatoric stress levels with a fatigue model.

6 . The method of claim 1 , further comprising generating the models of the cement sheaths.

7 . The method of claim 6 , further comprising determining an objective function for at least one selected cement composition.

8 . The method of claim 7 , wherein determining the objective function comprises determining at least one of a CO 2 footprint, cost of goods sold (COGS), or material usage.

9 . The method of claim 8 , further comprising determining a minimum value for the CO 2 footprint, cost of goods sold (COGS), or material usage.

10 . The method of claim 1 , further comprising determining a maximum value for the CO 2 footprint, cost of goods sold (COGS), or material usage.

11 . A method comprising:
selecting cement compositions; performing wellbore integrity analyses using models for cement sheaths, each cement sheath comprising a selected cement composition; determining a number of cycles to failure for each cement sheath; and determining an objective function for at least one selected cement composition.

12 . The method of claim 11 , wherein determining the objective function comprises determining at least one of a CO 2 footprint, cost of goods sold (COGS), or material usage.

13 . The method of claim 12 , further comprising determining a minimum value for the CO 2 footprint, cost of goods sold (COGS), or material usage.

14 . The method of claim 13 , further comprising producing the at least one selected cement composition based on the minimum value.

15 . The method of claim 15 , further comprising determining a maximum value for the CO 2 footprint, cost of goods sold (COGS), or material usage.

16 . The method of claim 11 , further comprising producing the at least one selected cement composition based on the maximum value.

17 . The method of claim 11 , further comprising generating the models.

18 . The method of claim 11 , further comprising receiving pressure, temperature, and time data for each cement sheath.

19 . The method of claim 11 , further comprising determining deviatoric stress levels from the wellbore integrity analysis for each cement sheath.

20 . The method of claim 19 , further comprising receiving the deviatoric stress levels with a fatigue model.
