The role of video aids in online teaching: engineering design as a case study. (2022)
Presentation / Conference Contribution
ABOLLE, J. and IYALLA, I. 2022. The role of video aids in online teaching: engineering design as a case study. Presented at the 2022 RGU annual learning and teaching conference (RGU LTC 2022): enhancing for impact, 21 October 2022, Aberdeen, UK.

The use of video aids has long been the subject of argument in pedagogic research (Hamel et al. 2019). With the recent shift from face-to-face to a more blended mode of teaching due to COVID, it is clear that video aids should be an inevitable part o...

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...

A critical analysis of open protocol for subsea production controls system communication.
Presentation / Conference Contribution
IYALLA, I., ARULLIAH, E. and INNES, D. 2017. A critical analysis of open protocol for subsea production controls system communication. In Proceedings of OCEANS 2017, 19-22 June 2017, Aberdeen, UK. New York: IEEE [online], article number 8084938, pages 2177-2183. Available from: https://doi.org/10.1109/OCEANSE.2017.8084938

Production control system communication protocols used in subsea fields are primarily proprietary to the subsea vendor. Due to the proprietary nature of this communication system, the operators encounter many challenges including obsolescence managem...

Environmental and economic considerations for the decommissioning of oil and gas infrastructure in Nigeria.
Presentation / Conference Contribution
AYENI, M., IYALLA, I. and MAHON, R. 2024. Environmental and economic considerations for the decommissioning of oil and gas infrastructure in Nigeria. In Proceedings of the 2024 Society of Petroleum Engineers (SPE) Nigeria annual international conference and exhibition (NAICE 2024), 5-7 August 2024, Lagos, Nigeria. Hosted on OnePetro [online], paper number SPE-223134-MS. Available from: https://doi.org/10.2118/223134-MS

When offshore structures reach their end of life it becomes necessary to remove them and return the environment to its initial state. Generally, there are three options for decommissioning which are complete removal, leave in place, and partial remov...
