  • Patent number: 8336627
    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.

  • Patent number: 8322420
    Abstract: Gravel packing of a wellbore penetrating a subterranean formation is carried out in a wellbore having a cased section and an uncased section that contains water-based drilling fluids. A first water-based displacement fluid that contains a shale inhibitor is introduced into the wellbore to displace the water-based drilling fluids from the uncased section of the wellbore. A second water-based displacement fluid is introduced into the wellbore to displace fluids within the cased section of the wellbore. A sand control screen assembly is run to a selected depth within the uncased section of the wellbore to facilitate a gravel packing operation. A gravel pack slurry containing gravel and a viscosified carrier fluid is introduced into the wellbore to facilitate gravel packing of the uncased section.

  • Patent number: 8316939
    Abstract: A method of installing a sand control screen assembly in a wellbore penetrating a subterranean formation is carried out in a wellbore having a cased section and an uncased section. The wellbore contains synthetic or oil-based drilling fluids containing drilled solids. A first water-based displacement fluid that contains a shale inhibitor is introduced into the wellbore to displace the synthetic or oil-based drilling fluids from the uncased section of the wellbore. A second water-based displacement fluid is introduced into the wellbore to displace fluids within the cased section of the wellbore. The sand control screen assembly is then run to a selected depth within the uncased section of the wellbore to facilitate a gravel packing operation.

  • Patent number: 8316952
    Abstract: A technique enables an improved filtering of sand, a desired distribution of produced or injected fluid, and a reduction in erosion of completion components positioned in a production or injection well. The technique employs a base pipe and a sand screen surrounding the base pipe. The base pipe comprises a plurality of flow restriction elements arranged in a selected pattern along the base pipe to provide a desired distribution of the fluid flowing into or out of the sand screen. The pattern of flow restriction elements also maintains a flow rate of the flowing fluid below an erosive flow rate across the entire sand screen.

  • Patent number: 8302310
    Abstract: A rod-based well screen is formed in place on a perforated pipe base by wrapping wire around the pipe base and a plurality of rods located around the outside of the pipe. The wire is welded sequentially to each individual rod as it is wrapped around the pipe. The welding and ground electrodes engage the wire and the rods respectively. The rod engaging ground electrode is positioned a short distance ahead of the wire being wrapped around the rods and the pipe base. The ground electrode includes a plurality of contacts. Each contact is mounted to pivot toward and away from a rod. Springs urge each contact toward a rod to hold the rod against the outside surface of the pipe base and to maintain good electrical contact between the contact and the rod. Each contact has a groove to guide the rod into position for welding to the wire.

  • Patent number: 8151883
    Abstract: A stimulation technique is provided for use in an open hole well. The stimulation technique utilizes a system which comprises one or more isolation devices positioned to isolate desired regions of the open hole well. At least one release mechanism is used to provide controlled release of stimulation material to a desired wellbore region of the open hole well. Additionally, a protection mechanism cooperates with each release mechanism to prevent undesirable contact between stimulation material and the surrounding wellbore wall of the open hole well. In many applications, the entire system is deployed and operated during a single trip downhole into the well.

  • Patent number: 8020617
    Abstract: A method of treating a formation with a well treatment fluid comprising a clay stabilizer comprising a polyamine ether before or during a well treatment such as cleanup, gravel packing, fracturing, or the like. The stabilizer can continue to inhibit fines migration in the treatment zone even after an aqueous fluid without the stabilizer, e.g. a production fluid or injection fluid, displaces the original treatment fluid. When the stabilizer is used in a viscoelastic system (VES) with an acid blend component, the viscosity of the VES is essentially unchanged relative to the VES alone without the stabilizer.
