A unique identifier (ID_20) is assigned to each well production device model (20) in the field model (10). The field model (10) is then connected to the control system (100). After installation of the well production devices (2) and the control system (100), the well production devices (2) and the control system (100) are configured according to information in the field model (10). Status and inventory information about the well production devices (2) and the control system (100) are retrieved. Finally, the field model (10) is updated or verified based on the retrieved status and inventory information.
