Hi-water I & II JIPs Multiflow I & II JIPs –Evaluation of the performance of multiphase flowmeters UKOOA oil-in-water guidelines Oil-in-water analysis JIP Ultraflow Wet-gas JIP NEL Wet Gas JIP Ultrasonic Meters for Oil JIP Fatigue Life of Fibre Ropes Industrial Water Use Joint industry projects

Headers Joint Industry Project –Investigation into the effect of headers on orifice metering systems –Lab and computational analysis –Basis for revision of standards and work on specific installations South Morecambe Terminal –50million Sm 3 /d of natural gas –AGA3 “any other configuration” which requires 145D or flow conditioner –ISO 5167 requires a flow conditioner –Other maintenance issues Headers JIP and consultancy

South Morecambe

South Morco

Computational analysis confirmed the following problems: – Swirl (up to 7 ° ) – Velocity distorted > 5% – Errors > 0.23% – One case = 0.75% South Morecambe Orifice plates were replaced by 3 ultrasonic meters installed in the 3 metering runs where the flow profiles were best

Multiphase metering Multiphase metering important technology for marginal field development and well management Technically, the simultaneous measurement of oil, water and gas flow is very challenging

In the 1990’s NEL Created a benchmark performance test through the Multiflow I and II Joint Industry Projects Tested the majority of the meters that had been developed into commercial products Performed factory acceptance tests for the likes of Amerada Hess, Philips, Shell, Petronas, BP, Kerr- McGee etc, etc. Provided consultancy and training for oil companies in Europe, the Americas, the Middle East and South East Asia NEL Involvement in Multiphase

The Multiflow JIPs Sponsors Amerada Hess Amoco BP ChevronTexaco Elf ExxonMobil JNOC Petrobras Philips Saudi Aramco Shell Schlumberger Total

Tullich Multiphase Metering Consultancy to identify suitable test site for two multiphase meters based on process data Selected ChevronTexaco Humble test site Devised test plan Supervised tests as independent witness Liased with Kerr-McGee / ChevronTexaco / Framo during tests Analysed the data and prepared the final report
