Underbalanced drilling facilitates the effective control of wellbore pressures - amongst several other important advantages - when compared to conventional drilling technology. However, this involves the flow of multiphase fluids, which introduces ad...

Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles. (2021)
Thesis
ALAITA, D.A. 2021. Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603672

Multi-phase flow is the type of flow common in the oil and gas industry, as oil reservoirs contain mixtures of oil, gas and water with sand particles from sandstone reservoirs. Accurate design of oil and gas production equipment greatly depends on de... Read More about Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles..

Computational fluid dynamics modelling of fluid flow inside fractured reservoirs. (2021)
Thesis
AL-MASHHADANIE, H.A.J. 2021. Computational fluid dynamics modelling of fluid flow inside fractured reservoirs. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1603660

Fractured media exist in most layers of the earth's crust, often dominating bulk properties of subsurface geological formations. Therefore, fractured media are involved in many key engineering sectors that impact humans living on Earth. Fractured for...

Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system. (2021)
Thesis
BALOGUN, Y. 2021. Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1357866

Relative permeability is affected by several flow parameters, predominantly operating temperature and fluid viscosity. Fluid viscosity changes with temperature, which correspondingly affects the relative permeability. Temperature is believed to have...
