Abstract. An experimental study featuring two phase gas-viscous oil flow was conducted in the NEL multiphase flow loop to assess the homogenisation effectiveness of the blind-t mixing spool that is commonly associated with many multiphase flow meter (MPFM) installations. The variance in phase distribution at the exit of the blind-t is described, alongside the effects of inlet flow structure on

ABSTRACT. Blind-tee is an important component in offshore piping systems for the multiphase flow mixing and measurements of oil and gas products. In this paper, a three-dimensional numerical study has been performed on the single and two-phase flows in the pipelines with blind tees in order to analyze the mixing conditions. The effects of blind-tee pipes on the gas-liquid bubble flow in

This paper describes two blind tests of a multiphase flow meter performed by ConocoPhillips and BP during 2010. The first test was at the Alpine oil field in Alaska, and the second was at the Colorado Engineering Experiment Station Inc. (CEESI) wet gas flow facility in Colorado. The same 74 mm MPM multiphase flow meter was used for both tests.

A multiphase flow meter is a device used to measure the individual phase flow rates of constituent phases in a given flow (for example in the oil and gas industry) where oil, water, and gas mixtures are initially co-mingled together during the oil production processes. Magnetic resonance makes use of a fundamental property of atoms and in
