Guided Interpretation #10 B10 - 2/12
B10.2 • First Interpretation: Using The Segmented Model
¾
In the PL Interpretation panel, click on Information to create a new interpretation. Keep
default name and OK.
¾
In the second dialog, click on the tab ‘Reference channels’; select the ‘Continuous’ method and
choose to Init based on ‘Surface rates and inflow types’ (below left).

¾
Click on the Define buttons on the Temperature and Pressure lines, and pick the channels in
Down 1.
¾
Move to the Temperature tab and click on the button to define the geothermal profile from
a point and a slope (above right).
¾
Tick ‘Simulate temperature’ and ‘Match temperature’ and select the ‘Segmented Model’. A
dialog pop-ups, asking for conversion of the Heat Loss Coefficient (HLC): in this model, the
HLC represents the heat loss from the wellbore to the outside, and it must be corrected for the
transient effects when changing the thermal calculation method (more on this in B10.3).
Answer No, as we will redefine the HLC.
¾
To define the HLC from the completion thermal properties, click on . Fill in the required
information:
o
Casing ID = 3.23 in, Casing OD = 3.5 in, Cement OD = 4.5 in
o
Casing and cement thermal conductivities: 50 and 30 W/m/
o
C respectively.
o
Change the rock thermal conductivity to 8 W/m/
o
C.
o
Change the heat capacity to 0.946 Btu/(lbm.°F).
o
Change the density (rhoe) to 5.52 g/cc.
o
Change the production time to 1E+8 hrs.
The heat loss coefficient value appears in red, indicating that the current cell value is different
from the value that will be obtained based on the completion geometry.
