\B3.0 LIMITATIONS\b
	 
	  The program is designed to work with pressures between 14.696 
	  psia (1.01325 Bara) and 6000 psia (400 Bara), and temperatures    
	  between 32 degrees F (0 deg C) and 400 degrees F (200 deg C).  
	  However, some of the correlations are not valid in the entire   
	  temperature-and pressure-range.  

	 
	  \U3.1 Gas Properties\u
	 
	  All natural gas-properties are limited to:
	 
			0.55 <= SPGG < 2.0
	 
			1.05 <= TEMPRD < 3.0
	 
			0 <= PRSPRD < 30
	 
	  In addition to the above limitations,  calculations of pseudo-
	  critical temperatures and pressures should not be performed    
	  for reservoir gases with SPGG > 1.3 and for surface gases with 
	  SPGG > 1.71.

	  For other gases the limitations are given by the same range for
	  TEMPRD and PRSPRD as for natural gas. 


	  \U3.2 Liquid Properties\u
	 
	  For most correlations used here the general limitations are:
	 
			0.55 <= SPGG < 1.4
	 
			14.696 psia < PRS < 6000 psia 
	 
			0.74 < SPGO < 1.0
	 
			20 SCF/BBL < GORS < 2000 SCF/BBL

	  Calculation of physical properties of water and the other 
	  liquids are limited by the following validity ranges:
	 
			500 psia < PRS < 6000 psia 
	 
			70 deg F < TEM < 250 deg F 
  

	  Specifically for water the salt-content must be limited by:

			0 % < NaCl < 25 %
	 
	  where it is assumed that all dissolved solids are expressed   
	  as equivalent sodium chloride concentration (NaCl-concentration).
