Towards assessing online uncertainty for three-phase flow metering in the oil and gas industry
A new three-phase (oil/water/gas) flow metering system has been developed for use in the oil and gas industries, based on Coriolis mass flow metering. To obtain certification for use in the Russian oil and gas industries, trials have taken place at the UK and Russian national flow laboratories, NEL...

| description | A new three-phase (oil/water/gas) flow metering system has been developed for
use in the oil and gas industries, based on Coriolis mass flow metering. To
obtain certification for use in the Russian oil and gas industries, trials
have taken place at the UK and Russian national flow laboratories, NEL in
Glasgow and VNIIR in Kazan, respectively. The metrology of three-phase flow
is complex, and the uncertainty of each measurement varies dynamically with
the operating point, as well as the metering technology, and other aspects.
To a limited extent this is reflected in the error limits allowed in national
standards, which may vary with operating point. For example, the GOST
standard allows errors in the oil flow rate of ±6% for water cuts of
less than 70%, which is increased to ±15% for water cuts
between 70 and 95%. The provision of online uncertainty for each
measurement, for example in accordance with the British Standard BS-7986,
would be highly desirable, allowing the user to observe in real time
variations in measurement quality. This paper will discuss how an online
uncertainty assessment could be implemented in the Coriolis meter-based
system. |
