comments: Drilled 17 1/2" section from 1431 m to 1436 m MD. Had to stop drilling due to prevailing problems with cuttings conveyer belt. Not able to restart belt.

comments: Conveyer belt could not be restarted as the shute in which the belt is running was full of cuttings. Opened forward shute on conveyer system to bring cuttings forward into skip. Emptied conveyer screws in shaker room into skips. Removed cuttings from conveyer belt shute with HP guns, fire hoses and suction hoses. Cleaned up cuttings from deck.

Meanwhile circulated well with low rate and rotated string at 20 rpm.
