ABSTRACT:
A method for simulating cuttings re-injection in a wellbore, that includes defining a mass balance equation for a solids bed, defining a mass balance equation for a suspension solids, segmenting the wellbore into a plurality of elements, wherein each element includes a plurality of nodes, segmenting a simulation into a plurality of time intervals, and for each the plurality of time intervals: simulating cuttings re-injection by solving the mass balance equation for the solids bed and the mass balance equation for the suspension solids for each of the plurality of nodes.
