  • Publication number: 20090211755
    Abstract: A technique facilitates a water flood, e.g. dump flood, operation. A standard electric submersible pumping system is deployed in a wellbore to draw water from an aquifer or water source zone along the wellbore. A shroud and a crossover port are used in combination with the submersible pumping system to redirect pumped water downwardly along an isolated flow path. The downward flow of pumped water is directed along the wellbore and injected into a desired, injection zone to facilitate recovery of oil or to perform other types of water flood operations.

  • Publication number: 20090173505
    Abstract: Techniques are provided for sealing a communication line within a device positioned in a wellbore. The communication line may be continuous and extends through a pass-through arranged generally longitudinally through the device. Swellable sealing material is positioned about and/or over the communication line which is placed in the pass-through of the device to form and maintain a secure seal once the device is submerged in a fluid that causes the swellable sealing material to expand.

  • Publication number: 20090090499
    Abstract: Embodiments of the present invention allow the placement of a stand alone device (valve) along a flow path, without a physical connection to the surface or reliance on the borehole for signaling, to provide a means to control the flow between reservoirs. This is achieved using a valve located in the flow path that can be actuated without sending signals down the borehole or well path and thereby eliminating the need for complicated signal lines and or fluid columns to actuate the valve.

  • Publication number: 20090078427
    Abstract: A system for completing water injection wells includes an injector well completion system. In an embodiment, an injector well completion system for liquid injection in a formation includes a casing string disposed in a wellbore having a tubing bore. The casing string includes a casing and a sliding sleeve. The sliding sleeve has a pressure control valve having open and closed positions, an actuator mandrel having a flow control device, and an injection pressure communication port. The open position of the pressure control valve actuates the actuator mandrel to align the flow control device and the injection pressure communication port to inject liquid from the tubing bore to the formation and generate fractures in the formation.

  • Publication number: 20090065199
    Abstract: A retrievable flow control device comprising a housing configured to sealably couple with a completion component. The housing may comprise a first port and a second port establishing a fluid pathway. The fluid pathway may regulate a fluid flow as the fluid flow passes through the fluid pathway. The housing may further comprise a coupling mechanism configured to releasably couple with a corresponding feature of the wellbore completion. The downhole flow control device may be configured to be retrievable independently of the completion component. The flow control device may comprise a check valve in the fluid pathway in order to substantially constrain the fluid flow to a single direction. In some cases, the flow control device may be configured to couple with a side pocket. In other cases, a concentric flow control device may be configured to couple with a screen base pipe, tubing, or stinger.
