This table provides CTL factors for correcting volumes of Gas and Bitumen at observed
temperatures to the volume at 15 C. Use this table if the following conditions exist.
 The liquid is a Gas or Bitumen
 Density @ 15 C is known
 Reference Temperature is 15 C
The test temperature and Calculated CTL are for informational purposes and will not be
used in calculations during operations.
