      <witsml:comments>Attempt to POOH without rotation. Pulled 150 ton while attempting to POOH. Slack off to neutral and begin rotating with 15-20 RPM. Lubricate out of hole with slow rotation from 5699m to 5605mm. Pump 50-90 lpm, 10-15 bar. Hookload 105-111 tons while pumping out of hole.  Lost returns when top stab entered sand zone. Continue working string through zone. Increase to 27 RPM while working pipe. Regained returns 5584m when bit exited sand zone.  Continue to lubricate BHA out of hole into 9-5/8" casing shoe at 5534m. :)</witsml:comments>
