sum24Hr: RIH with MDT toolstring #2. Positioned tool at sampling depth 3245 m MD. Took pressure point sample. Found toolstring stuck at 3245 m MD. Attempted to free stuck WL, applied max tension of 12000 lbs. Performed MDT fluid sampling at stuck point - filled 2 x 450 cc sample bottles. Rigged up for doing cut an thread fishing operation.
