On-command reamer allows for digital confirmation of multiple activations, blade status

摘要

EXPANDABLE REAMERS WERE developed to improve efficiencies and reduce risk when drilling through problematic formations in deepwater and other offshore wells. While mechanical and hybrid expandable underreamers have been used for some time in offshore applications, they have not provided the communication, operational reliability and flexibility that operators desire in high cost-per-foot drilling applications. Baker Hughes' newly commercialized GaugePro Echo aims to address these limitations. The on-command digital reamer minimizes the rathole, the bottom part of the wellbore that is drilled with the pilot bit only, and eliminates additional reaming trips typically required to drill this section.
