  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Time-Domain Physical-Optics Simulation Technique for Electromagnetic Imaging by Subsurface Radar

    Abstract - This paper presents a 2-D scalar numerical time-domain (TD) model based on physical optics (PO) for simulation of electromagnetic phenomena. This TD-PO model should be applied for detection and location of objects hidden in opaque media by subsurface TD radar system. The proposed approach allows considering of basic physical principles, governing electromagnetic radiation and ...

  • Frankfort Electric and Water Plant Board Verifies Distress on Ductile Iron Pipe Using Electromagnetics

    Commercial introduction of ductile iron pipe (DIP) began in the mid-1950s and was established as the most frequently selected material of choice for ferrous pressure pipe by the early 1970s. Due to the widespread use of DIP during a large expansion of pipeline infrastructure in the 1970s, there are many thousands of miles of pressurized DIP in operation today. Water and wastewater utilities ...
