| 20090084553 | SLIDING SLEEVE VALVE ASSEMBLY WITH SAND SCREEN - A system and method for completing a well with multiple zones of production is provided, including a casing having a plurality of valves integrated therein for isolating each well zone, establishing communication between each underlying formation and the interior of the casing, delivering a treatment fluid to each of the multiple well zones, and filtering produced fluids from each underlying formation. | 04-02-2009 |
| 20110056692 | SYSTEM FOR COMPLETING MULTIPLE WELL INTERVALS - A system includes a string that comprising a passageway and a plurality of tools. The system further includes an untethered object that is adapted to be deployed in the passageway such that the object travels downhole via the passageway and controllably expand its size as the object travels downhole to selectively cause one of the tools to capture the object. | 03-10-2011 |

| 20090101334 | MULTILAYERED BALL SEALER AND METHOD OF USE THEREOF - A multilayered ball sealer having a deformable layer. The multilayered ball sealer has an outer or intermediate layer that is deformable under pressure. In the former, the deformable layer may be water-soluble or hydrolysable. In the latter, the outer layer is a sheath that contains the deformable layer and adapts to its shape. A multilayered ball sealer may be used as a diversion agent by being suspended in a fluid injected into a wellbore and applying pressure to deform the shape of the intermediate layer such that the multilayered ball sealer adapts to the shape of a perforation opening on which the multilayered ball sealer has seated. | 04-23-2009 |
| 20100122813 | Method of Placing Ball Sealers For Fluid Diversion - A method for placing ball sealers within a well formed within a subterranean formation for sealing holes in a casing of the well is carried out by performing at least one of two operations. The first operation involves providing a tag with at least one ball sealer or a carrier fluid containing the at least one ball sealer to facilitate monitoring of the location of the ball sealer. A tag monitoring device is provided within the well for monitoring the location of the tag. The ball sealer and carrier fluid with the tag are introduced downhole into the well. Information from the monitor device regarding the location of the tag is communicated to a remote monitoring location to the thereby provide an indication of the location of the tag within the well to a surface location. In the second operation a container is provided within the well at a known location downhole within the well. The container contains at least one ball sealer. The ball sealer or sealers are released from the container within the well at the known location in response to an instruction initiated from a surface location. | 05-20-2010 |
