| 20090294128 | Wellbore Method and Apparatus for Completion, Production and Injection - 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 carrier fluid having gravel may be performed. | 12-03-2009 |

| 20140345869 | MOVING LINER FRACTURING METHOD - A method for treating a production wellbore involves a moving liner run-in on a work string to a treatment zone. Treatment fluid is pumped at high flow rate and pressure down the annulus, through a crossover to the interior of the liner and to the treatment zone. Zones co-extensive with the liner are shielded from treatment as a path of least resistance is defined into the treatment zone. Relatively tight liner clearance and high treatment flow rates prevent treatment of shielded zones. Flow rate is reduced, but pressure maintained, while the moving liner is pulled, exposing another zone. | 11-27-2014 |

In some applications, a separate nozzle may be mounted in cooperation with the base pipe port. The screen assembly further comprises a dispersion member having features positioned in a flow path of the injected fluid to disperse the flow and thus to reduce the erosive effects. | 05-05-2016 |
