    Abstract: A well logging tool apparatus is disclosed for conducting measurements in a borehole environment surrounding a borehole that traverses a subsurface formation. The apparatus includes an elongated conductive mandrel having a longitudinal axis, an antenna array positioned about the mandrel and including a transmitter for transmitting electromagnetic energy into the formation, and a sleeve positioned about the antenna array. The apparatus further includes a first set of electrodes and a second set of electrodes. Each electrode has an outer end that is exposed on the outer surface of the sleeve for conductive contact with an adjacent conductive borehole environment. Further, the first and second sets of electrodes are spaced longitudinally apart such that the transmitter is positioned longitudinally therebetween. Electrodes of the first and second sets are conductively interconnected with the mandrel such that when the well logging apparatus is operated in a borehole environment having borehole currents therein, one or more current path loops are provided for shorting borehole currents.

    Abstract: An apparatus and method provides an anchoring apparatus for use in a wellbore that comprises a gripping assembly and an actuation assembly. In one arrangement, the actuation assembly includes a motor and a module having at least a compressible element (e.g., a hydraulic module) between the motor and the gripping assembly. Upon activation, the motor actuates the hydraulic module to cause activation of the gripping assembly. In one arrangement, the anchoring apparatus is designed to pass through a tubing or other restriction in the wellbore. When in the retracted state, the gripping assembly of the anchoring apparatus has an outer diameter that is smaller than an inner diameter of the tubing. When in the expanded state, the gripping assembly of the anchoring apparatus has an outer diameter than is substantially the same as the inner diameter of the liner to enable engagement of the gripping assembly against the liner.
