This paper puts forward a method of using two wavelengths of near-infrared light to identify
the oil–gas-water mixed flow patterns. Propose a new method of multiple correlation …

Multiphase flow regime identification is a promising technology for ensuring flow safety in
marine gathering pipelines. An experimental study of air-water flow regime was conducted …

Accurate and rapid identification of multiphase flow patterns in long-distance pipelines is an
important means for flow assurance. In this paper, an experiment of air-water two-phase flow …

Gas-oil two-phase flow usually occurs during gas influx into the wellbore annulus of
deepwater drilling with oil-based drilling fluid or gas-oil production from the wellbore …

Sub-regimes of intermittent two-phase flows through a sudden expansion have been
investigated experimentally. Two pipes of 30 and 40 mm ID connected by a sudden …

Blowout is among catastrophic accidents in oil and gas drilling, and it is caused by abnormal
pressure resulted from gas kick from reservoir which cannot be prevented due to limits of …

In the petroleum industry, multiphase flow dynamics within the tubing string have gained
significant attention due to associated challenges. Accurately predicting pressure drops and …

Operators often require real-time measurement of fluid flow rates in each well of their fields,
which allows better control of production. However, petroleum is a complex multiphase …

Criteria for gas-oil two-phase flow transformation are essential guidelines that are used as
auxiliary equations for the calculation of two-phase flows in gas-oil based drilling fluids …

To identify conveniently multiphase flow regimes in subsea pipeline-risers, we study in this
paper experimentally two-phase flows in a 1657 m long pipeline with an S-shaped riser to …
