Hiding the irrelevant section of the data
With the Continuous method the goal is to match all the supplied data everywhere and it is
critical that we hide the sections where our model will not reproduce the measurements. There
are 2 such sections: (1) the part where re-circulation occurs and (2) the part between the
bottom of the top inflow and the sliding sleeve. The reason why we need to hide this second
section is that the temperature reacts to the flow as the fluid comes out of the formation. In
other words, for the top zone, the temperature sees behind the tubing. On the other hand, the
spinner, the density and the capacitance, only see the fluid when it enters the tubing through
the sliding sleeve. If we do not hide the top section on those curves, there will be no way to
match simultaneously all data and the regression will end up with an erroneous ‘in-between’
solution. We use the browser ‘Hide parts’ option to edit the VAFLOW curve first.
Hide the data between 681 and 840 m (recirculation part).

Repeat this operation on the range 555 – 655 m (top zone production below the sliding
sleeve).
Choose to ‘Apply on’: ‘Any type of data’ and inside the Interpretation #2 Input, tick the
DPDZ and CAP channels as shown below:
