Slugging flow in offshore oil & gas multi-phase transportation pipelines cause big
challenges as the flow regime induces flow and pressure oscillations in the multi-phase …

Accurate metering of slug flows is important in many industries that handle multiphase
products. For the oil and gas industry the harsh environmental conditions mean that non …

The occurrence of separation and slippage of the two phases in settling solid-liquid flow in
pipelines make the flow unpredictable and time dependent. Therefore it is paramount for the …

Numerous dual-modality tomography systems have previously been studied for multiphase
flow characterisation, however, the capability of the majority of these systems was only …

Modern oil/gas well drilling methods in particular in the offshore industry involve deviated
drilling in which the production tubing can be inclined at any angle between the vertical and …

Slurry transport has been a progressive technology for transporting a huge amount of solid
materials across the world in both, long distance and short commodity pipelines. The …

This thesis mainly presents the use of process tomography to study and measure flow
parameters in two phase horizontal and near horizontal flows. All static measurements were …

An experimental method of resolving flow regimes by utilizing the conductivity data
measured by Electrical Resistance Tomography (ERT) is presented. The method applies …

An 8-electrode electrical capacitance tomography (ECT) sensor located at the venturi throat
on a vertical pipeline is used to investigate the flow regime of gas-oil two-phase flow. The …

Gas-oil two-phase flow is widely encountered in oil exploitation and transportation pipelines.
It's complex and transient changes of flow regimes present a great challenge for accurate …
