- •
This paper introduces a method to estimate uncertainty bounds in field production.
- •
The method was tested in the PUNQ-S3 benchmark and in a real field case.
- •
The method improved the estimated uncertainty range in cumulative oil production for the PUNQ-S3 case.
- •
Results for the field case indicates that the uncertainty range in NPV can be twice larger that the range estimated by standard data assimilation.
