Shut off pumps, and pulled back inside shoe. Increased rotation to 110 rpm, and staged up pumps to 1200 lpm. Observed WOB increased to 20 klbs, Started to reciprocate string and observed WOB dropped to zero. Had full returns during this operation. Established drilling parameter and ran back to 3090m. No obstruction seen on the way inn.
