Geothermal PBL® Multiple Activation Bypass System

The Geothermal PBL® Multiple Activation Bypass System is specifically developed for geothermal drilling operations. The tool retains the design simplicity, reliability, and robust performance of the renowned DSI PBL® Multiple Activation Bypass System while incorporating advanced high-temperature-rated elastomer and lubricant technologies. The tool offers 100% bypass and split-flow capabilities, ball or dart activation, and the ability to activate or deactivate at any angle. It can be activated and deactivated up to five cycles as standard, with extended cycle tools available on request. The system enables operators to pump aggressive LCM or cement, boost circulation, or achieve optimized split-flow during a single run, whether drilling, backreaming, or simply spot hole cleaning. Available in a full range of standard sizes from 4 3/4 to 9 1/2 inches, with custom sizes available upon request. Temperature categories include standard applications up to 420°F/215°C and high-temperature applications up to 572°F/300°C, with further customization available for operations exceeding 300°C.
