Finite Element Modeling of Buried Longitudinally Welded Large-Diameter Oil Pipelines Subject to Fatigue
… design and construction of large-diameter buried pipelines primarily for crude oil transportation is governed in Canada by CSA Z662, ASME B31.4, and ASME BPVC Section VIII. Although these codes provide general guidelines on pipeline design, many aspects of modelling the pipeline are not given in …

Application of superparamagnetic nanoparticle-based heating for non-abrasive removal of wax deposits from subsea oil pipelines
Flow assurance is a critical problem in the oil and gas industry, as an increasing number of wells are drilled in deep water and ultra-deep water environments. High pressures and temperatures as low as 5°C in these environments hinder flow of hydrocarbon-based fluids by formation of methane hydrate …

Análise de transientes hidráulicos em oleodutos
… order to ensure that the piping and equipment of oil pipelines are not exposed to inadmissible pressures it is necessary to analyse hydraulic transients. The present work presents a computer program (TRANSH), developed by the author for calculating the hydraulic transients relevant to oil …

From Scar To Scaffold: The Afterlife of the Oil Pipeline for a Decarbonizing World
With over 86,000 kilometers of crude oil pipelines—and more than 2.13 million kilometers of total oil and gas pipelines in the United States as of 2024—many segments are already corroded and aging, deeply embedded within urban and ecological systems that are increasingly endangered. As the global …

The Development of a Knowledge-Based Wax Deposition, Three Yield Stresses Model and Failure Mechanisms for Re-starting Petroleum Field Pipelines. Building on Chang and Boger’s Yield Stresses Model, Bidmus and Mehrotra’s Wax Deposition and Lee et al.’s Adhesive-Cohesive Failure Concepts to better Underpin Restart Operation of Waxy Crude Oil Pipelines
… limits) to describe yielding of waxy crude oils cooled below the wax appearance temperature (WAT). At the time, the limits in rheological instruments were such that they never actually measured the elastic-limit, a key fundamental property. Using modern instruments, this research succeeds in …

Design and Modelling of Passive UHF RFID Tags for Energy Efficient Liquid Level Detection Applications. A study of various techniques in the design, modelling, optimisation and deployment of RFID reader and passive UHF RFID tags to achieve effective performance for liquid sensing applications
Sewer and oil pipeline spillage issues have become major causes of pollution in urban and rural areas usually caused by blockages in the water storage and drainage system, and oil spillage of underground oil pipelines. An effective way of avoiding this problem will be by deploying some mechanism to …

The doctrine of absolute liability and the right to a safe environment: issues and challenges in the liability of environmental polluters in Nigeria
Oil and gas exploitation and production in Nigeria, particularly in the Niger Delta region, is awash with pollution incidents with its attendant impact on the health of locals as well as foreseeable damage on the biodiversity of the region. Owing to this development, victims of environmental …

Instrumentation for low-conductivity magnetic induction tomography
… Impedance Tomography (EIT). In MIT, arrays of coils are employed to induce eddy currents within an object and to detect the resulting secondary magnetic fields. Conductivity and permittivity distributions are then reconstructed from the collected set of four-terminal transimpedance data. MIT has …
