  • Effect of particle size on sand deposition in single-phase and multi-phase pipelines. 
    Fajemidupe, Olawale T. (Cranfield University, 2016-11)
    Sand production in the life of oil and gas reservoirs is inevitable, as it is co- produced with oil and gas from the reservoirs. Sand deposition in petroleum pipelines poses considerable risk to the production of oil and ...
  • Effects of pipe orientation on sand transportation 
    Osho, Adeyemi Joseph (Cranfield University, 2013-11)
    Sand transport in hilly terrain geometry is different and complex to understand compared to horizontal pipeline, due to the influence of the geometry that greatly affect multiphase flow and sand behaviour at the dip. The ...
  • Experimental and numerical investigation of high viscosity oil-based multiphase flows 
    Alagbe, Solomon Oluyemi (Cranfield University, 2013-05)
    Multiphase flows are of great interest to a large variety of industries because flows of two or more immiscible liquids are encountered in a diverse range of processes and equipment. However, the advent of high viscosity ...
  • Experimental investigation of high viscous multiphase flow in horizontal pipelines 
    Baba, Yahaya D. (2016)
    Diminishing reserves of “conventional” light crude oil, increased production costs amidst increased world energy demand over the last decade has spurred industrial interest in the production of the significantly and more ...
  • Experimental investigations of two-phase flow measurement using ultrasonic sensors 
    Abbagoni, Baba Musa (Cranfield University, 2016-05)
    This thesis presents the investigations conducted in the use of ultrasonic technology to measure two-phase flow in both horizontal and vertical pipe flows which is important for the petroleum industry. However, there are ...
  • Flow measurement and monitoring using orifice plates 
    Papadopoulos, Christos E. (1996-03)
    The orifice meter is still commonly used for natural gas measurement despite its many limitations. Considerable efforts in recent years have resulted in improved knowledge of factors such as installation effects and the ...
  • Gamma radiation methods for clamp-on multiphase flow metering 
    Blaney, S. (Cranfield University, 2008-02)
    The development of a cost-effective multiphase flow meter to determine the individual phase flow rates of oil, water and gas was investigated through the exploitation of a single clamp-on gamma densitometer and signal ...
  • Gas-Liquid Two-Phase Flow in Up and Down Vertical Pipes 
    Almabrok, Almabrok Abushanaf (Cranfield University, 2013-10)
    Multiphase flows occurring in pipelines with a serpentine configuration is an important phenomenon, which can be encountered in heat exchangers used in a variety of industrial processes. More specifically, in many industrial ...
  • Hydraulic optimisation of service reservoirs to maintain water quality in distribution systems 
    O'Neill, S. (Cranfield University, 2001-10)
    Water supply utilities worldwide are under pressure to meet stringent water quality and supply demands Service reservoirs (SRs) or treated water storage reservoirs have been built for the dual function of maintaining ...
  • Intelligent Multiphase Flow Measurement 
    Ibrahim, Abba A. (Cranfield University, 2009-04)
    The oil and gas industry’s goal of developing high performing multiphase flow metering systems capable of reducing costs in the exploitation of marginal oil and gas reserves, especially in remote environments, cannot be ...
  • Metering practice and policy : an examination of battery electromagnetic meter calibration, performance and verification 
    Thomas, Alun Lewis (Cranfield University, 2009-09)
    The last twenty years has seen the rise to dominance of electromagnetic flowmetering (EFM)technology within the UK water industry network. In the last ten years, the introduction of battery powered EFM designs, for both ...
  • Modelling of an axial flow compact separator using neural network 
    Qazi, Nadeem (Cranfield University, 2009-05)
    A novel design axial flow cyclonic separator called I-SEP was tested with an extensive set of experiments using air-water two phase flow mixture at atmospheric pressure. These experiments provided valuable data on the ...
  • Modelling of transient gas-liquid flow and pigging in pipes 
    Lima, P. C. R. (Cranfield University, 1999-08)
    More and more transient gas-liquid operations in pipes are being successfully applied in the oil and gas industry. Pigging in two-phase pipelines, to remove liquid accumulation or for cleaning purposes, is an important ...
  • Modelling the two-phase performance of a centrifugal pump 
    Downham, S. E. (Cranfield University, 2000-03)
    A review was carried out which revealed that no simple mathematical model was available which could be used to predict the performance of a centrifugal pump when it is operating under two phase flow conditions. Experimental ...
  • Multiphase characteristics of high viscosity oil 
    Al-Awadi, Hameed (2011-11)
    Heavy oil production has drawn more and more attention in petroleum industry. The amount of heavy oil in the world is twice more than the conventional oil (low viscosity), which has been consumed rapidly from the past. ...
  • Multiphase flow measurement using gamma-based techniques 
    Arubi, Isaac Marcus Tesi (Cranfield University, 2011-03)
    The oil and gas industry need for high performing and low cost multiphase meters is ever more justified given the rapid depletion of conventional oil reserves. This has led oil companies to develop smaller/marginal fields ...
  • Oil/water separation in a novel cyclone separator 
    Stone, Andrew Colin (Cranfield University, 2007-08)
    Conventional bulk oil-water separation is performed in large gravity separators that take up large areas and potentially contain large volumes of hazardous material. An intensified bulk separator has the potential to ...
  • Optimal operation of tubular reactors for naphtha cracking by numerical simulation
