ABSTRACT:
The invention relates to improved systems and methods for selectively firing perforating guns in well bores and is concerned primarily with the production of a positive confirmation to the effect that each actuation at the operator control station intended to cause a firing of a particular shaped charge did or did not in fact result in the firing of that shaped charge. Such positive confirmation is accomplished by methods which involve the passage of measuring current from a constant current source through certain conductive loops to develop signals that are a function of the conductive loop resistance, the storage and comparison of said signals, and the display of resultant information. Due to certain phenomena, satisfactory measurement results will not be achieved unless a measuring current of substantial magnitude is used. The various parameters involved are treated.
