A method and a device for generating a three-dimensional image are provided. An example embodiment includes a system having a well casing surrounding at least one inner tubing string, where the inner tubing string has a distal section and a proximal section, an apparatus for removing a first fluid within the distal section of the inner tubing string, and an apparatus for removing a second fluid within the proximal section of the inner tubing string. A branch circuit analysis device is configured to be coupled to the user interface device via the first communications interface and at least one branch circuit by at least one test connector. A module loader loads the memory-data extracting module in a kernel region of the memory and sets a priority of the loaded memory-data extracting module to be higher than priorities of kernel processors loaded in the memory.
