The operator had highlighted the presence of extensive wax build-up in the casing string during the operation.


The operator made the decision to activate / open the PBL tool after each jetting operation to divert the flow through the PBL tool, hence allowing greater circulating rates needed to clean the hole. PBL positioned higher up in the string above the jetting sub.

Conclusion & Recommendation

The PBL Bypass System demonstrated its value to the operator by delivering the circulation boost needed to clean out the residual wax build-up from the casing ID when the jetting operation alone was unable to achieve the required outcome.
