Underreamer control, real-time feedback exercised via MWD system

摘要

Automated drilling with on-command digital underreaming proves the value of the IoT to oilfield operations. With oil and gas prices at their lowest levels in years, field operators - particularly those working in challenging deepwater conditions - continually look for ways to improve well efficiency, economics and safety. On-command digital underreaming exemplifies how the Internet of Things (IoT) can raise the level of communication, operational reliability and flexibility - and with it, can provide savings in time, cost and risk - in these high-cost-per-foot operations. Through IoT, sensors and actuators embedded in physical objects are linked through wired and wireless networks, often using the same Internet protocol that connects the Internet. The industry's first on-command digital reamer, the Baker Hughes GaugePro Echo, is powered by electrical current from the MWD system, which is generated by a mud-driven turbine or through wired pipe.
