Abstract
A ringout detection system may receive a plurality of surface weight-on-bit (SWOB) measurements from a surface weight-on-bit (WOB) sensor and a plurality of downhole weight-on-bit (DWOB) measurements from a downhole WOB sensor. A ringout detection system may identify a decrease in a WOB ratio between the plurality of SWOB measurements and the plurality of DWOB measurements. A ringout detection system may determine that the decrease in the WOB ratio exceeds a WOB ratio threshold. A ringout detection system may identify that ringout has occurred at the reamer based at least in part on the decrease in the WOB ratio.
