Circulation Sub and Downhole Hydraulics

The effects of a circulation sub, and its impact on downhole hydraulics, are designed to create a flow path between the pipe and annulus. Benefits include ECD reduction at the bottom hole, dislodge junk a debris, reduces surge pressure, and much more. A case study of a wellbore clean up with the following variables; total flow area (TFA), circulation sub location, and flow rate will quantify its impact. Several PVI software include circulation subs in its software such as SplitFlow, CleanMax, and SurgeMOD.
