Figure F22. Measurement-while-drilling/logging-while-drilling (MWD/LWD) bottom-hole assembly 12.25 inch configuration, Hole C0002N. PDM = positive displacement motor, PDC = polycrystalline diamond compact. XBAT = X-Bimodal AcousTic sonic, EWR = electromagnetic wave resistivity, DDS = drill string dynamic sensor, AGR = azimuthal gamma ray, PWD = pressure while drilling, AFR = azimuthal focused resistivity.
