1. A method comprising:
designing a designed cement blend, a designed injection schedule or a combination thereof for a wellbore isolation barrier, wherein the designing is performed using instructions stored in at least one non-transitory memory that, when executed by one or more processors, configure the one or more processors to perform a method comprising:
(i) inputting, by an analysis application, a first set of inputs into a first model, wherein the first model is a computational fluid dynamics (CFD) model, and wherein the first set of inputs comprises a cement blend, one or more customer inputs, and an injection schedule;
(ii) inputting, by the analysis application, a second set of inputs into a second model, wherein the second model is a geochemistry model, wherein the second set of inputs comprises a first output from the first model;
(iii) inputting, by the analysis application, a third set of inputs into a third model, wherein the third model is a mechanical property model, wherein the third set of inputs comprises a second output from the second model;
(iv) determining, by the analysis application, a near wellbore stress state from an input, wherein the input comprises a third output from the third model, the first output from the first model, a set of user inputs, or combination thereof;
(v) comparing, by the analysis application, a failure property threshold of at least one of i) rock, ii) cement, iii) casing, iv) or combination thereof, to the near wellbore stress state; and either:
(vi)(a) in response to the near wellbore stress state exceeding the failure property threshold, modifying, by the analysis application, the cement blend, the injection schedule, or combination thereof to provide a modified cement blend, a modified injection schedule, or both and returning to step (i) wherein the cement blend, the injection schedule, or both are updated with the modified cement blend, the modified injection schedule, or both, respectively, or
(vi)(b) in response to the near wellbore stress state not exceeding the failure property threshold, generating, by the analysis application, the designed cement blend, the designed injection schedule, or combination thereof for the wellbore isolation barrier.
