  • Monitoring Steam-Assisted Gravity Drainage (SAGD) with EIT
    2014-04-24
    Steam-assisted gravity drainage (SAGD) is a technique that has been developed to efficiently extract bitumen from deep reservoirs. We propose using electrical impedance tomography (EIT) for real-time monitoring of SAGD wells to maintain optimal operating conditions. Several electrode configurations along the pipelines and measurement strategies are presented and compared.
  • Open Electrical Impedance Tomography (OEIT) File Format
    2014-04-24
    Electrical impedance tomography (EIT) creates tomographic images from surface electrical stimulation and measurement. Many research and commercial devices have been made, with correspondingly many data formats, which negatively impacts the ability to share data. To address this issue, we have developed the OEIT data format, an XMLbased flexible container format for EIT data. We describe its features and structure.
  • Slope Stability Monitoring through Impedance Imaging
    2014-04-24
    A technique for monitoring slope stability in a geological setting through impedance tomography is demonstrated. An iterative absolute Gauss-Newton solver simultaneously constructs estimates of the underground resistivity distribution and movement of the stimulation and measurement electrodes. The results are a step toward demonstrating that a cost effective and potentially predictive monitoring technology could be practical.
