Abstract (en)
[origin: WO2013138622A2] A localized inflow tracer may be flushed from a gravel pack surrounding a base pipe of a production well by outwardly venting the inflow tracer. The base pipe may include a non-perforated section disposed adjacent to one or more perforated sections. A tracer carrier may be disposed circumferentially about at least a portion of the non-perforated section of the base pipe. An inflow tracer may be released from the tracer carrier into production fluid within the gravel pack proximate to the non-perforated section of the base pipe such that the inflow tracer is flushed from the gravel pack into individual ones of the one or more perforated sections of the base pipe and transported with the production fluid. The inflow tracer may be prevented from being flushed directly from the tracer carrier into the base pipe due to a lack of permeability of the non-perforated section of the base pipe.
