Rubis Guided Session #5: Thermal Option
• Rub
GS05 - 20/24
Accept the settings. Back to the Simulation page, initialize the model
, run the
simulation
and go to the temperature log plot.
The temperature is now displayed from the surface to the bottom of the reservoir:
Fig. C04.5 • Temperature logs
from surface to reservoir bottom – Run 1
Above the reservoir, the temperature of the formation is assumed to remain constant and
equals to the geothermal profile. The well model is not transient above the reservoir. As a
consequence, the wellbore temperature profile above the reservoir drops back to the
geothermal profile during the warm back period. The temperature decrease between 0 and
3000ft is due to the ocean temperature.
If the evolution of the wellbore temperature in the overburden (i.e. above the reservoir) is
important, it may become necessary to simulate the overburden: in this case, the wellbore will
be segmented in the overburden, and the heat exchange will be rigorously simulated in the
vicinity of the wellbore. This simulation is the purpose of the remaining of this session.
From Run 1, create a new run, ‘Run 3’ using the toolbar
and go to the
geometry dialog
. Select the layer ‘Shale 1’, and insert a layer
.
Change the name of the layer to ‘Overburden’, set the top to 3000ft (corresponding to the
ocean floor) and the thickness to 5000ft.
You should get the following display:
