    • Asymmetric source acoustic LWD for the improved formation shear velocity estimation 

      Chen, Tianrun; Wang, Bing; Zhu, Zhenya; Toksoz, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
      Most acoustic logging while drilling (LWD) tools generate a single pure borehole mode (e.g., dipole or quadrupole) to estimate the formation shear velocity. We propose an approach where multipole modes are generated ...
