    Abstract: Systems, methods, and devices relating to a sourceless X-ray downhole tool are provided. By way of example, such a downhole tool may include an X-ray generator, an X-ray detector, and data processing circuitry. The X-ray generator may emit some X-rays out of the downhole tool and some X-rays internally through the downhole tool. The X-ray detector may detect some of the X-rays that return to the downhole tool, as well as some of the X-rays that pass internally through the downhole tool. The data processing circuitry may gain-stabilize the X-ray detector based at least in part on the X-rays that passed internally through the downhole tool and were detected by the X-ray detector.

    CPC classification number: G01V3/30

    Abstract: An antenna (3) of an electromagnetic probe used in investigation of geological formations GF surrounding a borehole WBH comprises a conductive base (31) and an antenna element (32). The conductive base (31) comprises an opened non-resonant cavity (33). The antenna element (32) is embedded in the cavity (33) and goes right through the cavity. The antenna element (32) is isolated from the conductive base (31). The antenna element (32) is coupled to at least one electronic module via a first 34A and a second 34B port, respectively. The electronic module operates the antenna so as to define a simultaneously superposed pure magnetic dipole and pure electric dipole.
