Abstract: Downhole Camera systems and methods. Certain systems include a high-speed video camera configured with a 360 degree optical field-of-view, a jet-flushing system capable of temporarily displacing debris substantially simultaneously along all azimuths within the optical field-of-view, and optionally a downhole real-time image processing system for reducing the amount of captured video transmitted to surface. Certain methods include capturing a set of images downhole using a high-speed video camera having a 360 degree optical field-of-view, substantially simultaneously temporarily displacing debris in the optical field-of-view for at least a portion of the time the camera is capturing video using a jet-flushing system capable of projecting flushing fluid substantially simultaneously along all azimuths in the borehole. The methods may also involve pre-processing the set of images to reduce the number of images or reduce the amount of information transmitted to surface.
