19
Sw Modelling Enhancements Sw V. Height Curves

• Options extended to allow Gas over Oil
  calculations of Pc
• Gas/Oil contact is entered plus Gas Density
• Pc in the gas zone calculated by adding the Pc in
  the Oil to the Pc in gas
• IFT correction factors can be set for both Oil
  and Gas
• Hence the same function can be used for both fluid
