Claims19
A method comprising:
- providing a model of cement induction time, wherein the model of cement induction time comprises a regression model of induction time data and physicochemical data;
- designing a proposed cement composition, based at least partially, on the model of cement induction time;
- preparing the proposed cement composition;
- modifying the proposed cement composition to produce a modified cement composition if a predicted induction time of the proposed cement composition does not meet or exceed a target induction time;
- calculating the predicted induction time of the modified cement composition using the model of cement induction time;
- comparing the predicted induction time of the modified cement composition to the target induction time;
- and
- preparing the modified cement composition if the predicted induction time of the modified cement composition meets or exceeds the target induction time.
