Onshore and offshore multiphase pipelines provide a safe and effective solution for the transport of fluids from wells to production plants in the oil and gas industry. For the control of the accumulated amount of liquid present in the pipeline (the so-called liquid holdup) and for the regular maintenance of the pipeline, pigs (Pipeline...

The transportation of high viscosity oil is an ongoing research topic for quite some years because of its importance in industrial applications and the increasing energy requirements of the world population. The water lubricated oil core with a core-annular flow configuration is a viable option for the transport of high viscosity oil. It was...

Currently, the paper producing industry is a significant energy consumer and contributes to the excessive greenhouse emissions. In order to become carbon neutral by 2050, it is evident that the paper industry must become more sustainable as well. Most of the energy is consumed in the dewatering process. Therefore, optimizing this process is key...

In the oil and gas industry, it is crucial that the transport of hydrocarbons through long pipelines occurs in the most efficient and safest way. These pipelines can cover up to several tens to hundreds of kilometres. Hydrocarbons are not the only fluids present within the pipelines, often they are filled with a mixture of oil, gas, water and...

The production of heavy oil from reservoirs requires much more effort than the production of lighter oils. This is due to the fact that this heavy oil has a significantly higher viscosity; namely, typically a factor 10 to 10000 more viscous than water. This higher viscosity makes the transport through pipes less economically viable due to the...

The transport of highly-viscous oil in the core-annular flow regime in a horizontal pipe is investigated with a numerical simulation study. In this flow type the viscous oil is lubricated by a water annulus along the pipe wall. The Launder-Sharma low-Reynolds number k-ε turbulence model is used with the Volume-of-Fluid solver in interFOAM. Three...

Steady state multiphase flow models are used for the design and operation of pipelines that are used in the oil and gas industry. The predictions obtained with these models contain uncertainties, which arise from model assumptions and simplifications, and from uncertainties in the input parameters. In this thesis we investigate the effect of...

This study was aimed at improving the accuracy of the model predictions for the minimum fluid and inner wall temperatures for cold, low-pressure start-up of wells that produce oil or gas. Due to the large pressure drop over the well head choke, the so-called Joule-Thomson cooling will give a very low temperature of the<br/>expanding gas jet. Low...

Pipelines are used in many industries as a means of transporting fluids, for example in the oil and gas industry. Pigs are devices that move through such pipelines, for instaoce to cleao the pipeline or to perform internal inspections. They are driven by a pressure difference over the pigs. Since this is a risky operation, there is a strong...

Stratified two phase flow is one of the flow regimes that is of importance in multiphase flow transport through pipelines, such as used for example in the oil and gas industry. Its application also extends to chemical production, energy conversion and food processing. The phenomenon of turbulence further complicates the stratified flow behaviour...

Pigs (pipeline inspection gauges) are free moving piston-like devices, that are used for inspecting or cleaning pipelines in for example the oil and gas industry. Here they are used for onshore and offshore pipelines, where they are propelled by the production fluids. A better control of the velocity of the pig in the pipeline can be achieved by...

In the oil and gas industry, pipeline networks are used to transport the production fluids from wells to production plants. During normal operation, the pipelines need regular cleaning and inspection. Typically, the pipeline maintenance is performed by pigging, which refers to using devices known as “pigs ”(Pipeline Inspection Gauges) to perform...

Natural gas wells produce small amount of liquids along with the gas. During the initial part of the reservoir life, the gas velocity in the well tubing is large enough to drag the liquid upwards. As the well matures, the reservoir pressure starts to decline leading to a decline in the gas velocity in the tubing; here the gas momentum is not...

In natural gas production, along with gas, a small amount of liquid is produced. Towards the end of a reservoir life, the gas velocity reduces due to a decline in pressure. A low gas velocity in a gas well causes undesirable liquid accumulation (loading) in the production tubing. One of the ways to postpone liquid loading is by injecting...
