From my understanding, it is still speculation that Shell is using GTL stock in Ultra. That speculation is based upon the low published NOAK in the SN data sheet. Shell has announced the Pearl GTL plant in Qatar is now up to full capacity, but I have yet to see any proof that Ultra is derived from those stocks.
