Downhole Energy Source Broom Stick (Primacord) Charge This distributed charge was developed by Amoco and licensed to Davis Equipment. It used primacord wrapped around grooved wooden dowel rods about five feet long to make charges of 50 feet or longer. The objective was to reduce the downward detonation velocity so as to match the surrounding formation velocity. Benefits included a ghost-free down-going pulse rich in high frequency and minimal generation of ground roll.
