摘要： One embodiment of the present invention discloses a shot indication device that indicates the orientation of a downhole tool that is inside of a wellbore at a particular time. The shot indication device can also be used to determine the orientation of a perforating gun with shaped charges at the instant the shaped charges are detonated. The shot indication device is comprised of an indicator housing secured within the downhole tool. Formed within the indicator housing is an annulus whose axis is parallel to the axis of the downhole tool. Disposed inside of the annulus is an indicator element that freely moves about the circumference of the annulus.
