... authors (e.g., Rosenbaum 1974; Schmitt et al., 1988; Tang and Cheng, 2004). Existing analyses, however, address the wireline situation where the logging tool occupies only a small portion of the borehole. In many of the analyses, the presence of the logging tool is even neglected. For modeling the LWD...
