Abstract
Method, system and apparatus to produce hydrocarbons includes a packer apparatus with a swellable packer element around primary and secondary flow paths, the packer is configured to block flow in a portion of a wellbore annulus. The method includes disposing sand control devices having shunt tubes and a packer within a wellbore adjacent to a subsurface reservoir. The packer is then set within an interval, which may be an open-hole section of the wellbore, and gravel packing the sand control devices in different intervals. Hydrocarbons are produced by passing hydrocarbons through the sand control devices with different intervals providing zonal isolation. In some embodiments, intervals may be alternatively packed and plugged, wherein the plugged intervals are not packed.
