The PBL Bypass System has provided a simple and reliable solution to various drilling problems, including lost circulation and limited circulating rates for effective hole cleaning operations for over 20 years. The tool has proven to be a financially beneficial incentive for operators, by substantially reducing down time and circulation hours. The PBL Bypass System has proven significantly effective to operators in some of the most extreme onshore and offshore drilling environments around the world.
The tool is a component of the bottom hole assembly and is located above the MWD and LWD tools. It is hydraulically activated (ball activated) and simple enough to be operated by rig personnel directly and does not necessitate DSI personnel on-site. A special safety feature of the tool is, that whenever pumps are turned off, the sleeve shifts to the closed position and isolates the ports, which eliminates the u-tube effect and assures full well integrity.
The company continues to innovate and advance its patented PBL system as well as introduce new tools utilizing technology to address a variety of other drilling applications.
Dosco is the exclusive distributor of the PBL Multiple activation bypass system in Romania.
