comments: RIH WL toolstring for pulling NPR plug from surface to TRSCSSV at 496 m MDRT. Found that TRSCSSV was closed. Decided not to wait for cmt unit - production needed to equalize and open TRSCSSV on F-12 to re-start production. 

Hooked up pump on rig floor to needle valve on lubricator to equalize and open TRSCSSV in F-4. Ran through TRSCSSV at 496 m MDRT and verified that it was fully open.

comments: RIH and latched GS pulling tool into NPR plug at 2649.7 m. Jared down to equalize ports in the plug. Waited 15 min for pressure across plug to equalize. Pressure dropped to 10 bar. Bleed off pressure. Released NPR plug by jaring up once. Got 150 kg increase in string weight. Waited 30 min to allow elements to retract.

comments: POOH with NPR plug. Observed that weight dropped back to up weight while POOH. RIH and latched GS pulling tool into NPR plug at 2649.7 m. Pressured up well to 10 bar. Jarred down to equalize ports in the plug. Waited 15 min for pressure across plug to equalize. No pressure drop observed. 

Released NPR plug by jaring up 105 hits. Adjusted stress point on cable after 60 hits with jar. Got approx 300 kg increase in string weight. Bleed off pressure. Waited 30 min to allow elements to retract.
