    Abstract: Annular flow experiments in horizontal flow in pipes were conducted with emphasis on wave characteristics (wave velocity, wave frequency) and liquid film thickness. The experiments were conducted using water/air in a 0.0504m pipe diameter with a total flow loop length of 28.68m. Liquid film thickness in all the flow matrix in this study, were obser... Show More

    Published: 21 January 2020
    Abstract: Several networks of pipelines in Nigeria oil and gas industry have failed catastrophically in the last two decades because most oil pipelines operate in a corrosive environment and transport corrosive fluids. This research experimentally investigates the corrosion of a carbon steel pipeline immersed in a typical Niger Delta Offshore Environment. Th... Show More
  • Mathematical Approach to Determination of the Pressure at the Point of Leak in Natural Gas Pipeline

    Published: 10 February 2020
    Abstract: In this paper, a model is developed for the estimation of the pressure at the point of leak in a natural gas pipeline experiencing leak. The model is developed by comparing two equations developed for leak localization in natural gas pipeline corresponding to the upstream and the downstream sections of the pipeline respectively. The determination o... Show More
  • Utilization of Stranded Associated Flare Gases for Electricity Generation in Situ Through Gas-to-Wire in the Niger Delta

    Abstract: The large volume of stranded associated gas in the Niger Delta which has sadly been flared holds great prospect in addressing Nigeria’s electricity problem if properly harnessed. The predominance of central electricity production system has over the years shown incapability in generating enough electricity needed by the Nigeria populace. Even with ... Show More
