Fig. B02.26 • Apparent velocity log calculated
B02.4.3 14B• Zone Rate
The top Rate calculation zone was created at the very top of the perfos, in a zone where the
apparent velocity is not stabilized.
 Resize this zone interactively or use the button of the zone toolbar. In the ‘Rate
calculation zones’ tab, change its position to about 8469-8505 ft.
 Click on ‘Zone rates’.
 Accept the default model and correlation: Water-Hydrocarbons (L), ‘ABB Deviated’.
 Go to the ‘Rate calculation’ page.
 Go to ‘Surface Match’. Enter the surface rates as follows: qw=3265 STBD; qo=1670
STBD; qg=225 MSCFD.
 Select ‘Match Surface’.
 Reset the slip multiplier to 1 (followed by Apply). In this case the slip multiplier is not really
affecting the error on density. Note that we could decide that the solution should not at all
be constrained by the surface rates at all and reset the Vpcf multiplier to 1 as well.
