I am trying to get FUTURE to match exactly the attached Excel forecast, but, as you can see from the .ftrx file, the FUTURE profile has some differences, even when I take care to specify identical changes in uptime etc. Can you help?


There are two causes of the discrepency
- the start point for reading the table (what cum oil to look up at prediction start) was selected to be "Cumulatives at start of prediction" which honours UR; in other words FUTURE was correcting (as is normally sensible) the forecast for the difference between forecast and actual to date. Change to "Date of start of prediction" to reproduce the forecast without this correction
- In File /Settings for current model, choose the option "Use extra calculation steps to honour exact dates" (of new wells and planned changes).

With these two changes, you get an exact match.
