comments: Decided to attempt to pump available nitrogen on rig, to start up well flowing the well. Production department lined up from nitrogen racks. Hooked up on wellhead on killwing manifold. Emptied 4 nitrogen racks. Was able to increse WHP from 54 -68 bar.
Meanwhile Schlumberger performed stationary logging.
