    摘要： An apparatus, method and computer-readable medium for evaluating an earth formation. A logging tool having a non-conductive mandrel and a conducting sleeve having at least one antenna that are electrically connected is conveyed into a borehole in the earth formation. At least one of the antennae has a coil oriented at a non-zero an angle to a longitudinal axis of the logging tool. The at least one antenna is activated, and an effect of a signal received by a receiver coil on the logging tool due to at least one of (A) an eccentering of the logging tool, and (B) a coil misalignment is reduced.

    摘要： Multicomponent measurements made in a cross-bedded earth formation are processed to give one or more equivalent TI models. Resistivity information about the cross-bedding is obtained from one of the TI models and a measured cross-bedding angle. Resistivity information about the cross-bedding may also be obtained using a combination of two or more of the equivalent TI models.

    摘要： A method for making acoustic logging measurements includes grouping received acoustic waveforms into one of a plurality of groups, each group being representative of a measured borehole condition (e.g., a range of measured standoff values and/or a range of measured azimuth angles). The waveforms stored in at least one of the groups are stacked so as to obtain an averaged waveform. The averaged waveform may be further processed, for example, via a semblance algorithm to obtain at least one acoustic wave slowness.
