Abstract
A system for simulating a wellbore used for cuttings re-injection, that includes functionality to obtain as input to the system at least one wellbore design parameter for the wellbore, at least one operating parameter for the cuttings re-injection, and a slurry design for a slurry to be injected into the wellbore, functionality to segment the wellbore into a plurality of elements, wherein each element includes a plurality of nodes, and functionality to perform a simulation at a current time interval. The functionality to perform the simulation includes functionality to update a solid accumulation at a bottom of the wellbore at the current time interval and functionality to perform for each of the plurality of nodes, until the wellbore reaches a steady-state condition for the current time interval, at least one calculation using the at least one wellbore design parameter, the at least one operating parameter, and/or the slurry design.
