Hybrid analytical hierarchy process model for the optimisation of marginal field development in Nigeria. (2024)
Thesis
DANMADAMI, A.M. 2024. Hybrid analytical hierarchy process model for the optimisation of marginal field development in Nigeria. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2795516

The slow pace of marginal field development in Nigeria poses a critical challenge to the nation's energy security and economic stability, given the reliance on oil and gas revenues. This stagnation stems from the lack of a systematic decision-making... Read More about Hybrid analytical hierarchy process model for the optimisation of marginal field development in Nigeria..

Development of drilling optimization models for autonomous rotary drilling systems. (2023)
Thesis
AMADI, K.W. 2023. Development of drilling optimization models for autonomous rotary drilling systems. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2445718

The growing global energy demand and strict environmental policies motivate the use of technology and performance improvement techniques in drilling operations. Traditional drilling methods depend on the effectiveness of the human-driller in the mana... Read More about Development of drilling optimization models for autonomous rotary drilling systems..

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..

Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis. (2022)
Thesis
EGBE, P.I. 2022. Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-2071873

Due to the significant non-productive times and recovery costs associated with stuck pipe events in oil and gas drilling operations, there is value in being able to predict an impending stuck pipe event. To achieve this, the use of numerical cuttings... Read More about Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis..

Computational fluid dynamics modelling of pipeline on-bottom stability. (2017)
Thesis
IYALLA, I. 2017. Computational fluid dynamics modelling of pipeline on-bottom stability. Robert Gordon University, PhD thesis.

Subsea pipelines are subjected to wave and steady current loads which cause pipeline stability problems. Current knowledge and understanding on the pipeline on-bottom stability is based on the research programmes from the 1980s such as the Pipeline S...
