Control mud losses through the PBL® Bypass System, using high concentrations of LCM in the 12-¼” vertical hole section of an exploration well in a pre-salt environment without having to POOH to control losses.
As a standard procedure for this traditional operator, the 8 ¼” PBL® Bypass System was included in the BHA to allow high concentrations of LCM to wellbore if losses were encountered.
Utilizing the PBL Bypass System as part of the drilling BHA saved four trips and resulted in huge cost savings for the client. Drilling through pre-salt layers, losses occur quite often, and given the complexity of drilling BHAs and high cost for drilling rigs, the PBL® Bypass System is highly recommended in these scenarios. Additionally, the use of an extended ball catcher sub is recommended as it offers increased cycle availability for the PBL® Bypass System, if required.
