Choke size while coiled tube lifting a well with nitrogen

[amahaminer]

when performing nitrogen lifting job for a well through coiled tubing what is the optimum choke size to use during the job?? Full open choke???

You should rather ask this question and you will get the answer : What should I choke back the well??

i asked this question -ELgharib- as i found some people suggest to choke down while lifting a well with nitrogen and they claim that it is better to choke down to prevent nitrogen from escaping from the well.

what do u think??

chock size of 1/2 " is optimum
