Abstract | Apparatus and method for investigating underground formations surrounding a borehole, comprises: a drill bit (28); an optical probe (30) having substantially the same outer diameter as the drill bit; a drive mechanism (22), operable to cause the drill bit to drill a hole in the formation when the apparatus is in the borehole, and to advance the optical probe into the drilled hole; and an optical system (36), arranged such that when the optical probe is in the drilled hole, light from a light source (32) is directed into the optical probe, light entering the probe from the source is directed at the formation around the drilled hole, and light entering the probe from the formation around the drilled hole is directed to a detector. |
