if the cuttings in hole are not circulated out then it causes bridges between the BHA and the borewall and hence for the same flowrate you will get a higher pressure at surface

Months ago, I was on a drilling rig, sudden pack off happened & caused sudden pumping pressure increase, no mud return, drillstring stucked, couldn't free it. We made back off, left part of drillstring in the well, made cement plug & side tracked the well !!
