Real-time downhole video logging of wells was introduced to the industry in the early 1990s (Rademaker et al. 1992; Cobb and Schultz 1992; Grenoilleau 1994; Maddox et al. 1995), enabled by the development of fiber optic cables that provided a data transmission rate sufficient to allow for real-time capture of video images. Early cameras had a single camera aimed downward from the bottom of the tool string, with a light source either in front of or behind the camera. Modern downhole video imaging tools have both a camera aimed axially down the wellbore and one or more side-viewing cameras, with illumination for all the cameras, as shown in Fig. 11.1 (Cramer et al. 2019) and Fig. 11.2 (Tymons et al. 2019).
