Decision-support for decommissioning offshore platforms. (2023)
Thesis
EKE, E.C. 2023. Decision-support for decommissioning offshore platforms. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2270718

An estimated 2,500 offshore decommissioning projects are expected to be completed between 2018 and 2040 with significant accompanying challenges. In this research, a decision model for decommissioning offshore platforms is developed. The decommission... Read More about Decision-support for decommissioning offshore platforms..

Gas diffusion transport characteristics and mathematical description of membrane systems with application for biogas upgrading. (2023)
Thesis
OGUNLUDE, P. 2023. Gas diffusion transport characteristics and mathematical description of membrane systems with application for biogas upgrading. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2071771

Greenhouse gas emissions (GHGs) and their effects have been a matter of global concern over the past decade. With growing energy demands to support developing economies, there has been a challenge of harnessing and utilizing renewable energy to meet...

Real-time monitoring of cement sheath integrity under high-angle HPHT wellbore conditions. (2023)
Thesis
WILCOX, L.B. 2023. Real-time monitoring of cement sheath integrity under high-angle HPHT wellbore conditions. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2071847

The lengthy time span over which the cemented well needs to retain its integrity is a massive challenge today. The cement plugs in abandoned wells, in conjunction with the annular cement sheath, need to prevent leakages well beyond the life of the we...

Adaptive swarm optimisation assisted surrogate model for pipeline leak detection and characterisation. (2023)
Thesis
ADEGBOYE, M.A. 2023. Adaptive swarm optimisation assisted surrogate model for pipeline leak detection and characterisation. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2071535

Pipelines are often subject to leakage due to ageing, corrosion and weld defects. It is difficult to avoid pipeline leakage as the sources of leaks are diverse. Various pipeline leakage detection methods, including fibre optic, pressure point analysi...

Complexity in measuring the higher education institution scope 3 emissions. (2023)
Thesis
NAYAK, A.A. 2023. Complexity in measuring the higher education institution scope 3 emissions. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2271448

The first step in addressing climate change is to measure carbon emissions derived from greenhouse gases (GHGs). The greenhouse gas protocol is widely accepted and implemented by organisations worldwide. This protocol categorises carbon emissions int...

Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs. (2023)
Thesis
KUKHA HAWEZ, H.R. 2023. Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1987869

Fractured hydrocarbon reservoirs play a significant role in the world economy and energy markets. Fluid injection (normally water) forces the hydrocarbons out of the reservoirs. Geomechanics, externally applied stress on the rock, play a significant... Read More about Coupled geomechanics and transient multiphase flow at fracture-matrix interface in tight reservoirs..
