Abstract
An apparatus for producing fluid from a well intersecting a plurality of producing formations. The apparatus includes a pumping system lowered into the well on a production tubing. The well is separated into upper and lower production zones by a packer installed in the well. Fluid is communicated upwardly in the well from the upper zone through a first flow conduit and from the second zone through a second flow conduit. Fluid from both zones is combined and produced upwardly in a single stream. The amount of fluid produced from each zone can be determined with a flow meter which will measure the amount of flow produced from one or more of the zones.
