  • Patent number: 9222316
    Abstract: A system and methodology facilitates extending the reach of coiled tubing during a well operation. The technique employs tubing which is deployed along wellbore. A plurality of extended reach devices is positioned along the tubing. Each extended reach device has at least one internal guide member oriented for extension into an interior of the tubing. The guide member engages and guides the coiled tubing during movement of the coiled tubing along the interior of the tubing, thus enabling an extended reach during a wellbore servicing application.

  • Patent number: 9109411
    Abstract: A method for reducing friction between a coiled tubing and a wellbore includes: generating a periodic pressure wave; coupling the periodic pressure wave to a coiled tubing in a wellbore; and propagating the periodic pressure change in the coiled tubing wherein a friction force between the coiled tubing and the wellbore is reduced. The shape of the periodic pressure wave can be modulated to a form similar to that of a sinusoidal waveform.

  • Publication number: 20140327443
    Abstract: A technique facilitates detection of an object passing along a conduit, such as a wellbore conduit. The object is released into an internal passage of the conduit, and the conduit is monitored at a given location or locations along the conduit. Movement of the object past the location or locations is detected by a sensor, such as a sensor positioned externally with respect to the internal passage of the conduit. Passage of the object is monitored via detection of a unique electro-magnetic signature as the object moves along the interior of the conduit and past the location.

  • Publication number: 20140207390
    Abstract: A system and technique for dynamically and historically evaluating useful life of coiled tubing. Methods are detailed wherein a monitor and system are equipped for enhanced evaluating of coiled tubing fatigue life based in part on the orientation of the coiled tubing during use. This may be obtained through the tracking of a seamweld of the coiled tubing. Additionally, reliability of the coiled tubing over various uses may be determined on an ongoing basis as a result of acoustically acquired data during operations. In either case, the monitor may be of a magnetic flux data detection variety.

  • Publication number: 20140174726
    Abstract: A technique employs the use of oscillations downhole to facilitate a desired functionality of a downhole tool. According to this technique, a tool is initially conveyed downhole and operated to perform a function that relates to a downhole application. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e.g. freeing the tool from a stuck position.

  • Patent number: 8705318
    Abstract: A method for aggregating data for a drilling operation. The method includes acquiring the data from a number of data sources associated with the drilling operation, synchronizing a timing of the data for aggregating the data to generate synchronized aggregated data, determining a drilling context based on the synchronized aggregated data, and assigning the determined drilling context to the synchronized aggregated data. The method further includes analyzing the synchronized aggregated data in the drilling context to generate an analysis and presenting the analysis to at least one user.

  • Publication number: 20130246029
    Abstract: A method of estimating extended reach for a downhole line traversing a deviated section of a well. The method may include storing line and well architectural and physical data and then performing a static analysis of substantially axial-exclusive estimated friction between the line and well wall during conveyance (which may be thought of as the contact force due to interference therebetween). A one dimensional dynamic analysis may then be performed. Thus, based on these factors, speed of the conveyance, vibration parameters of an incorporated vibration tool, etc., an efficient simulation of the conveyance may be run.

Real time data may be compared to historical or nominal data for the coiled tubing. Another method includes monitoring, in real time or near real time, the status of tubing dimension (thickness, diameter, ovality, shape) during a coiled tubing operation, such as acidizing, fracturing, high pressure operations, drilling, and wellbore cleanouts. 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.
