  • Patent number: 10782115
    Abstract: A method for detecting radial deformation in a winding of a transformer may include synthetic aperture radar (SAR) imaging of the winding using ultra high frequency (UHF) electromagnetic signals in a first instance of the winding to obtain a first image of the winding; SAR imaging of the winding using UHF electromagnetic signals in a second instance of the winding to obtain a second image of the winding; and comparing the first image of the winding and the second image of the winding to detect a radial deformation in the winding. The UHF electromagnetic signals may be transmitted as a plurality of successive sinusoidal signals, where frequencies of the successive sinusoidal signals gradually change from a first frequency to a second frequency.
    Type: Grant

  • Publication number: 20090192712
    Abstract: Method, system and computer program product for controlling a production/injection operation for an oilfield, the oilfield having a first wellsite with a producing well advanced into subterranean formations with geological structures and reservoirs therein. Data from a plurality of data sources is collected with respect to a production/injection operation, wherein the collected data includes oil production data and fluid injection data. The collected data is stored in a database. Extracted data relating to a selected performance parameter to be monitored is extracted from the database, the extracted data is processed, and a graphical representation of the processed data is dynamically displayed to enable monitoring of the selected performance parameter.
