Claim 0:
1. A computer-implemented method, comprising:
inserting, by a monitoring system, units of smart polymers into drilling fluid pumped into a well during a drilling operation, wherein the units of smart polymers are pressure-responsive;
storing, by the monitoring system, an insertion timestamp associated with each unit, each insertion timestamp indicating a time that each unit was inserted into the drilling fluid;
capturing, by a camera positioned at a sensing location and linked to the monitoring system, continuous images and observed characteristics of drilling mud exiting through an annulus of the well and containing the units of smart polymer;
determining, by the monitoring system and using the continuous images, the observed characteristics and the insertion timestamps associated with each unit of smart polymer, an estimate of a bottom hole pressure (BHP) at a drill bit of the drilling operation, wherein determining the estimate is based at least in part on executing image processing algorithms, machine-learning models, and deep-learning models; and
suggesting, by the monitoring system and based at least in part on the estimate of the BHP, changes to be made to drilling parameters for the drilling operation.
