Zusammenfassung:Resuming communication along a wellbore after a drilling stand or other occurrence that reduces the flow rate of the drilling fluid into a borehole being drilled in a drilling procedure or causes perturbations in the pressure of the drilling fluid in the borehole by measuring a first flow rate of drilling fluid being pumped into the drillstring during the drilling procedure before adding a section of drill pipe to the drillstring or before the pressure perturbation and increasing the flow rate of the drilling fluid being pumped into the drillstring above the first flow rate after the section of drill pipe has been added to the drillstring or the pressure perturbation has occurred.
