If the radial flow line needs to be moved, click on the white dotted line and drag the line
accordingly.
Note:
the rate history is at this stage of the visit made of about 30 000 values. Before running
any model it is necessary to reduce the number of flow period in order to make the simulation
duration reasonable.
To do so, go to Edit rate, select all the rate data
, open the processing box
, select the
tab ‘Simplify’ and impose a ‘% Delta’ of 5% for rate simplification.
Press OK, the rate number is reduced to around 2150 point.
After setting the radial flow line, start the interpretation using the automatic model
to
estimate skin and adjust the early time match.
To access this option, select 'Interpretation' and then press Shift +
. A message
indicates that the model is being generated.
Then, open the 'Model' dialog to add the closest faults, using the intersecting sealing fault
option: choose 'Intersecting faults – Any angle' in the Boundary model section.
Add a fault at
950 and 4700 ft
at an intersecting angle of
90°
. Set
kh to 13000 mDft
and
C to
0.011 bbl/psi
and
S to -1
. Run the model clicking 'Generate' and the match
between the model and the data in the loglog plot of Build-up # 2 should be very close.
See Figure E01.13.

Change the extracted group to build-up to #15 (main build-up).
You can use the pick option
in the ‘Extract dP’ dialog: in the pick dialog, you need to first
erase the current selection with .
