Abstract: Real-time field data that is associated with a hydrocarbon reservoir drilling field is obtained. A carrying capacity index (CCI) and a cutting concentration annulus (CCA) are determined based on the real-time field data.

One or more parameters associated with the hydrocarbon reservoir drilling field are adjusted based on the comparison result through a user interface (UI).
