Duty Cycle Estimation From Bending Moment Magnitude

Abstract

A method comprising: disposing a bottom hole assembly (BHA) comprising a Rotary Steerable System (RSS) into a borehole, obtaining bending of the drill bit (BOB) data with a measurement assembly disposed on the BHA, classifying the BOB data into a neutral RSS configuration or a geostationary RSS configuration, determining t1 based at least on a neutral RSS configuration, wherein t1 is the total time during a neutral RSS configuration, determining t2 based at least on a neutral RSS configuration, wherein t2 is the total time during a geostationary RSS configuration, and determining a real time Duty Cycle based at least on t1 and t2. Additionally, a bottom hole assembly (BHA) comprising a Rotary Steerable System (RSS) disposed into a borehole, and a steering control system a configured to perform the method described above.
