Abstract
A method and apparatus for electrically detecting the presence of an initiator in a downhole tool by measuring the resistance of an initiator, electrically isolating the initiator from a power source, supplying current to the initiator less than the current necessary to initiate the initiator, detecting voltage through the initiator, and calculating the resistance of the initiator.
Claims20
A method for measuring the resistance of an initiator comprising:
- electrically isolating the initiator from a power source;
- supplying current to the initiator, wherein the supplied current is less than the current necessary to initiate the initiator;
- detecting voltage through the initiator;
- and
- calculating the resistance of the initiator.

An apparatus for measuring the resistance of an initiator in a perforating gun string comprising:
- an initiator coupled to a current limiter through a voltage isolation device;
- a voltage isolation device which isolates the initiator from a power source;
- and
- a voltage measurement device coupled to the initiator through a voltage isolation device wherein
- the measured voltage is used to calculate the resistance of the initiator.
