Abstract
A method, system and apparatus associated with the production of hydrocarbons are described. One apparatus includes a swellable packer element around a primary and a secondary flow path, wherein the packer is configured to block flow in a portion of a wellbore annulus. One 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. With the packer set, gravel packing of the sand control devices in different intervals may be performed. Then, hydrocarbons are produced from the wellbore by passing hydrocarbons through the sand control devices with the different intervals providing zonal isolation. In some embodiments, intervals may be alternatively packed and plugged, wherein the plugged intervals are not packed. In addition, the method may also include disposing the sand control devices and packer into the wellbore in conditioned drilling fluid. The conditioned drilling fluid may be displaced adjacent to the sand control devices by a carrier fluid. Again, once the packer is set, the gravel packing the intervals with the…
