TÜV SÜD NEL launches real-time subsea meter calibration tool

20 July 2021

TÜV SÜD National Engineering Laboratory (NEL) has launched NEL-SURE, a real-time software tool for the verification of subsea multiphase flow meters (MPFM), that will help operators to optimise reservoir management and revenues.

As equipment is deployed to deeper fields, routine calibration is unviable due to the excessive cost of removing subsea MPFMs for laboratory-based validation. While MPFMs are calibrated before installation, laboratory-based flow regimes differ greatly to actual subsea conditions. Consequently, over time significant measurement errors result in fiscal loss, for both operators and taxation authorities.

NEL-SURE provides in-situ, continuous calibration of MPFMs and uses a traffic light system to alert operators to a meter’s health. The software can also accommodate a virtual meter to provide a secondary measurement for verification of the MPFM’s output. This will help to improve process and control decision making, increase productivity and safety, and reduce environmental impacts through the early identification of potential system failures.
