Stock tank oil determination of wax appearance temperature (WAT) and wax dissolution temperature can be determined through the use of cross polar microscopy (CPM) or Differential Scanning Calorimeter (DSC). Live fluid WAT can be determined using Near-Infrared (NIR) system or PFI equipment. High temperature gas chromatography is used to identify the paraffin distribution in a reservoir fluid, which together with the WAT, is used to tune deposition models.
