Analysis of the performance challenges affecting state-owned refineries in Nigeria: a systems thinking approach. (2022)
Thesis
IHEUKWUMERE, O.E. 2022. Analysis of the performance challenges affecting state-owned refineries in Nigeria: a systems thinking approach. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1712811

This research aimed to understand how the significant factors that lead to performance challenges across Nigeria's state-owned refineries operationalise to drive their sub-optimal performance. As such, unlike previous studies, this thesis proposed to... Read More about Analysis of the performance challenges affecting state-owned refineries in Nigeria: a systems thinking approach..

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..

Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process. (2020)
Thesis
STAROST, K.J. 2020. Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process. Robert Gordon University [online], PhD thesis. Available from: https://openair.rgu.ac.uk

Polymer nanocomposites are becoming established widely across the industry due to (among other reasons) their lightweight performance advantages, and ability to meticulously target material properties with great control and precision. Despite the ben... Read More about Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process..

Petrophysical and geomechanical characterization of a marginal (Wabi) field reservoir in north-central Niger Delta. (2019)
