An exploratory study of localisation drivers and barriers of oil and gas service firms: a case study approach.
The purpose of this thesis is to explore and understand the localisation phenomenon from a geographical, cultural, technical and governmental theme to help explain why the level of local content in the oil and gas engineering and technical services private sector tends to flatten out at specific …

Investigations towards the development of a novel multimodal fibre optic sensor for oil and gas applications.
Oil and gas (O&G) explorations are moving into deeper zones of earth, causing serious safety concerns. Hence, sensing of critical multiple parameters like high pressure, high temperature (HPHT), chemicals, etc., are required at longer distances. Traditional electrical sensors operate less …

Cross sensitivity analysis of optical fibre-based sensing for high pressure, high temperature measurement in oil and gas applications.
… pressure, temperature, flow rate, vibrations and displacement in harsh environment are often desired in the oil and gas industry. Pressure and temperature are the most important parameters among them. Changes in pressure and temperature have a major role in many downhole processes and they …

CFD modelling of flow-induced vibration under multiphase flow regimes.
… (MFIV) in pipe bends poses serious problems in oil and gas, nuclear and chemical flow systems. The problems include: high amplitude displacement of the pipe structure due to resonance; fatigue failure due to excessive cyclic stress, induced by fluctuating forces; and structural wear, due to the …

Developing a novel mechanistic model for four-phase oil-water-gas-sand stratified flow in a horizontal pipe.
Presence of sand and solid particles in untreated petroleum sometime is inevitable. Although many techniques have been developed to prevent sand particles from entering the pipeline, such as downhole gravel packs, these downhole sand control devices can cause significant production loss due to the …

Gas-condensate flow modelling for shale gas reservoirs.
… resources in the world unlocking vast reserves and reshaping the landscape of the oil and gas global market. Gas-condensate reservoirs represent an important part of these resources. The key feature of these reservoirs is the condensate banking which reduces significantly the well deliverability …

An investigation of casing structural integrity in shale gas horizontal wells during hydraulic fracturing using FEA and machine learning algorithms.
Unconventional oil and gas operators are currently facing the challenge of casing lateral buckling and/or deformation during shale gas wells stimulation through hydraulic fracturing. Failure of the casing during this process can lead to huge financial loss, catastrophic consequences and even …

Computational fluid dynamics modelling of multi-phase flow transition in presence of solid particles.
… 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 detailed understanding of this flow phenomena. …
