Abstract
A well perforating system with an orientation marker. A well perforating system includes a perforating gun with a rotating perforating assembly and an orientation marker operative to indicate an azimuthal orientation of a perforating charge of the perforating assembly at a time of detonation of the perforating charge. The marker includes a portion biased by gravitational force to a vertically downward position as the assembly rotates. A method of indicating azimuthal orientation of a perforating charge at detonation includes: assembling the charge into a rotating perforating assembly of a perforating gun; attaching an orientation marker to the gun; permitting a portion of the marker to remain in a vertically downward position as a result of gravitational force acting on the portion, until the charge is detonated; and in response to detonation of the charge, fixing an orientation of the portion.
