Abstract: A downhole measurement tool configured to be run through a bore includes a source and a 3-component receiver. The source is configured to emit a source signal, which may be a compressional or a shear wave, into a volume of material surrounding the bore. The source signal propagates through the volume of material surrounding the bore and reflects off of features disposed within the volume of material surrounding the bore. The three-component receiver includes a first element, a second element, and a third element. The first element is oriented in a first plane, orthogonal to an axis of the bore, and receives a first component of the set of reflections of the source signal. The second element is oriented in the first plane, orthogonal to the first element, and receives a second component of the set of reflections of the source signal. The third element is oriented parallel to the axis and receives a third component of the set of reflections of the source signal.
