According to the Carrier manual you can use the following...
11.1.3 - lubricant The 06T screw compressor is approved for use with the following lubricants: • Castrol Icematic SW220 (Carrier specification PP47-32) • Lubrizol Emkarate RL220H (Carrier specification PP47-13

Sw220 u can use

DO NOT USE ANY OF THE OILS YOU HAVE MENTIONED above.
Only use Castrol SW220 as previously stated by Brian.
Why do you want to change the oil ?
More to the point are you a refrigeration engineer ? if not then get someone who is to work on this chiller preferably Carrier.
Some of the oil you mentioned above is Mineral Oil and a refrigeration engineer would know you don't use it on a R134A machine which only use's a Polyester oil ( POE).
