In the ‘Aspect tab’ set the ‘corrected production’ oil rate curve in red .
The objective of a derived channel is to create an output data set resulting from n input
channels. Writing ‘Y’ the Y values in the inputs, the values of the new channel are defined as:
Ynew[t]= f(Y1[t], Y2[t], Y3[t], …, Yn[t],a1,a2,…, ak).
Where the parameters ‘a1’… ‘ak’ are user defined constraints.
In this particular case, the channel is defined in such a way that the resulting ‘corrected
production oil rate’ channel is set strictly to Zero whenever a shut-in is detected in the build-up
indicator channel, and will leave the rate as it is originally in ‘raw production’ anywhere else.
As a derived channel, the corrected production would be extended automatically as the input
oil rate gets updated via the database. All we would need to get this channel up-to-date is to
pick the future build-ups so that the build-ups definition is up-to-date.

Select the Plot view for Well#1 , and in the ‘Plot’ ribbon click on Show . Select
‘production #1 ‘corrected production #1’ and ‘shut-in’, to view the difference between the
original production and the modified one.
