  • Publication number: 20100059225
    Abstract: Apparatus and methods for selectively and safely reversing flow in coiled tubing used for wellbore cleanouts are disclosed. One apparatus includes a section of coiled tubing having a main flow channel, at least two flow-preventing valves in the section of coiled tubing, each adapted to close the main flow channel upon attempted flow reversal; and at least one actuator adapted to deter closing of the flow-preventing valves. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Patent number: 7658226
    Abstract: Although the methods have been described here for, and are most typically used for, hydrocarbon production, fluid diversion measurement systems and methods are described. One method includes inserting a tubular tubing having one more fluid injection ports into a wellbore, injecting a treatment fluid through the injection port, and determining differential flow of the treatment fluid at one or more wellbore based on measuring the concentration of at least one particular component of a wellbore fluid located in the annulus formed between the wellbore and tubular; and using the measured parameters in realtime to monitor, control, or both monitor and control diversion of the fluid.

  • Patent number: 7424176
    Abstract: Apparatus and methods for terminating and anchoring fiber optic connections are disclosed. One apparatus includes a sealed body enclosing a passage for one or more optical fibers terminating in connections proximate a first end of the sealed body, the sealed body having a diameter less than an internal diameter of an oilfield tubular, the sealed body having a second end adapted to sealingly engage and anchor an end of a fiber optic carrier conduit, the second end connecting the sealed body to the fiber optic carrier conduit.
