Abstract:
1. An apparatus for producing hydrocarbons comprising: a first tubular member having a permeable section and a non permeable section; a second tubular member disposed within the first tubular member, wherein the second tubular member has a plurality of openings that provide a fluid flow path into the interior of the second tubular member; a barrier element disposed between the first tubular member and the second tubular member, the barrier element being configured to isolate a first chamber from a second chamber formed between the first tubular member and second tubular member, wherein the first chamber includes the permeable section of the first tubular member and the second chamber includes the plurality of openings in the second tubular member; at least one conduit disposed between the first tubular member and second tubular member, wherein the at least one conduit provides at least one fluid flow path between the first chamber and the second chamber through the barrier element; wherein the at least one conduit is configured to provide adequate leak-off during gravel packing operations and to provide sufficient choking during production operations; and at least one shunt tube secured to at least one of the first tubular member and the second tubular member and configured to pass through the barrier element.
