1. A bottomhole assembly comprising:
a tubular defining a central flow passage;
a camera having an aperture and attached to an outer surface of the tubular and the aperture oriented away from the outer surface of the tubular;
a lost circulation media reservoir circumferentially surrounding at least a portion of the outer surface of the tubular, the lost circulation media reservoir being adjacent to the camera, the lost circulation media reservoir comprising actuable gates along a periphery of the lost circulation media reservoir; and
a trigger communicably coupled with the actuable gates and configured to actuate the actuable gates, wherein the camera is configured to capture: a first image of a portion of a reservoir prior to release of lost circulation media from the lost circulation media reservoir in response to actuation of the actuable gates by the trigger, and a second image of the portion of the reservoir subsequent to release of the lost circulation media from the lost circulation media reservoir in response to actuation of the actuable gates by the trigger.
