I ran two scenarios in pForecast, why is the behavior not as expected?

The two scenarios are called “Test RNB” and “Test project”. The difference between these 2 scenarios is only that in Test project case, I added an extra 12 days to production stop in the year of 2026.

When comparing the oil volumes, I could see that oil volumes in the Test project case are lesser than in Test RNB case. But I am wondering since the only limitation in both scenarios is the gas capacity and in 2027 there is available gas capacity.

So why are the Test project wells not able to produce more in 2027 and onwards to catch up what they have missed in 2026? Why do they produce exactly the same in the 2 runs from 2027 and onwards?

Answer: 

To maintain the volume produced for a well, the production profile used for that well must be ‘’volume-based’’ well to preserve the total planned production. 

1. To do so, under the forecast properties, select “Production Potential”. Select the button on the right-hand side: Switch to property view.
2. Select the volume-based profile.
3. Check that your production profiles are set to Yes.
