Abstract
A method performed with a computing system for determining well integrity includes receiving a selection of a well configuration of a well, and receiving a selection of a wellbore operation performed with the well configuration. The selected well configuration includes one or more casing strings and a production tubing extending from adjacent a wellhead of the well to adjacent a bottom of the well. In some examples, the method further includes determining, based on the well configuration and the wellbore operation, a characteristic of the well at or adjacent the one or more casing strings and the production tubing during the wellbore operation, and modifying the well configuration to remove the production tubing. In some examples, the method still further includes determining, based on the modified well configuration and the wellbore operation, the characteristic of the well at or adjacent the one or more casing strings during the wellbore operation.
