Drilled from 6,313 to 6,561 ft measured depth (MD)/5,693 to ~5,929 ft true vertical depth (TVD). Surveyed at 6,430 ft MD and wiped hole up to 4,619 ft. Observed 30,000# to 40,000# over pull. Lowered pipe to 5,306 ft. Drill string stuck and no circulation. Raised and lowered string to free pipe and establish circulation. Reamed up and down through tight hole from 5,100 to 5,300 ft. Lowered drill sting back into well and drilled from 6,561 to 6,679 ft MD. Rotary chain broke. Repaired rotary chain. |

Pulled drilling assembly/coring out of the well. Laid down NOV coring assembly and drill collars. Rigged down wireline equipment. Laid down directional drilling assembly.
