Abstract: A method and apparatus for determining whether a tubing conveyed perforating (TCP) gun has fired by detecting a change in characteristics of the flow of an oil well. A method and apparatus detects the presence of fluorescent tracer dye to determine whether or not a TCP gun has fired. The method and apparatus detects a change is capacitance, or fiber optic electrical properties to determine whether or not a TCP gun has fired. The method and apparatus detects the number of charges fired to determine whether or not all TCP guns have fired and also provides a method and apparatus for determining the contributions of injection wells to producing wells by introducing fluorescent tracers into injection wells and detecting the presence of the fluorescent tracers at production wells. A method and apparatus is provided for placing fluorescent dye particles in a gravel pack to sense when a gravel pack is deteriorating by detecting the tracer dye particles in the well flow.
