Purpose of the REGIONS Section
The REGIONS section divides the reservoir according to
– Variations in reservoir characteristics
– For reporting purposes
Examples:
– Different PVT properties and equilibration characteristics couldbe assigned to areas of the grid separated by a sealing fault
– Fluid in place could be reported by fault block or leasehold position
The REGIONS section is optional

Use: Reporting Purposes
1. FIPNUM (fluid in place regions)
are defined in the REGIONS
section
2. In the Solution section:
RPTSOL
FIP=2 /
3. The PRT file now shows the
fluids in place both originally &
at each report step

Output Controls
For a report in the PRT file:
– RPTREGS in REGIONS Section
• BOUNDARY can be used to limit this output
– RTPSOL (FIP=1,2 or 3) in SOLUTION Section
– RPTSCHED (FIP=1,2 or 3) in SCHEDULE Section
For 3D viewable output:
– INIT in GRID Section = regions keywords
– RPTRST (FIP) = fluids in place
}same result
