  • Patent number: 7827668
    Abstract: A connection between coiled tubing and a connector includes a plurality of dimples formed by a tubing, each dimple is disposed within a respective pocket formed in a connector to form at least two rows of dimple-pocket connections, wherein the fit of the dimples within the pockets of the rows graduates from tighter to looser along the length of the connection. The connection may further include a seal member positioned between the tubing and the connector positioned between at least two of the rows of dimple-pocket connections formed. A method of connecting coiled tubing to a connector includes the steps of graduating the dimple-pocket connections from tighter to looser along the length of the connection.

  • Patent number: 7810555
    Abstract: The invention generally relates to an apparatus and/or a method for moving an round flexible member into and out of a well bore, and particularly, to an injector with two or more gripping members which bind the outer surface of the round flexible member; two or more actuators which cause the gripping members to bind or release the round flexible member; and at least one reciprocator for translating a gripping member to move the round flexible member, or for repositioning the gripping member. A method of translating a round flexible member is also provided which includes the steps of binding the outer surface of a round flexible member with at least one gripping members by engagement with an actuator, and translating a gripping member by reciprocator to move the round flexible member.

  • Patent number: 7794135
    Abstract: Disclosed are apparatus and methods for preparing wellbore viscous treatment gels from dry polymer and water. The apparatus includes an eductor which slurries dry polymer with water, at least two input tubes, wherein one input tube is connected with the eductor, and another to a water source. The apparatus also includes a mixing chimney connected to the input tubes. The mixing chimney includes a lower input section with inlets connected to the input tubes wherein a jet of metered dilution water is applied at high pressure to the incoming polymer-water slurry stream. This mixture is then accelerated in a circular, and preferably upward, motion where it is sheared against the wall of a central section of the chimney, without the use of an impeller. The chimney further includes an output section that comprising holes circumferentially located, through which the mixture passes from the central section and into a hydration tank.
