  • Publication number: 20210222523
    Abstract: A subsurface representation may define simulated subsurface configuration of a simulated subsurface region. The simulated subsurface region may include simulated wells, and the simulated subsurface configuration may define simulated correlation between the simulated wells. Subsurface configuration of wells may be compared with the simulated subsurface configuration to generate similarity maps for the wells. Simulated wells may be matched to the wells based on the similarity maps and the arrangement of the wells. Correlation between the wells may be determined based on the simulated correlation between the matched simulated wells.

  • Publication number: 20210048556
    Abstract: Correlation matrices may be used to simultaneously correlate multiple wells. A correlation matrix may be generated for individual pairs of multiple wells. The values of elements of the correlation matrices may be determined based on matching between segments of the multiple wells and segments of one or more computational stratigraphic models. An N-dimensional space including an axis for individual wells may be generated. Directed walk may be performed within the N-dimensional space to generate paths representing scenarios of correlations for segments of the multiple wells.

  • Patent number: 10750582
    Abstract: An electrode adjustment device and a vehicle positioning system for positioning the electrode adjustment device adjacent a furnace. The electrode adjustment device is utilized for adjusting the electrode during maintenance of the furnace (e.g., removal of the electrode for replacement or repair, repair of the refractory material, or other like furnace or electrode repair). When the electrode adjustment device is moved to a location adjacent the furnace, it is used to apply force under the bottom electrode to break the connection between the bottom electrode and the furnace. After the connection is broken the bottom electrode is pushed up into the furnace vessel by the electrode adjustment device until the electrode can be removed. After removing the bottom electrode, the electrode adjustment device is covered with debris and can be cleaned adjacent the furnace.
