A method and apparatus detects the presence of a fluorescent tracer dye, a change in capacitance, or a change in 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 determines 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. The invention places 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.
