Figure F7. LWD tool bottom-hole assembly diagram. The whole borehole assembly is on the left (105 m total length), and geoVISION 675 is on the right with measurement points of gamma ray and resistivity. DPG = drill pipe guide, NMDC = nonmagnetic drill collar, GVR = geoVISION resistivity tool, APWD = annular pressure while drilling. Bit size = 8½ inch.
