Background
During a drilling campaign in Kuwait, circulation debris caused by well construction caused critical MWD, LWD, and RSS components of the BHA to fail, requiring the BHA to be tripped out of hole—resulting in costly, time-consuming equipment replacements. The operator wanted to prevent circulation debris– related problems and NPT in future wells.
