  • Patent number: 8939219
    Abstract: A system and method for monitoring and controlling a snubbing unit having traveling slips and stationary slips are provided. Position sensors are associated with the slips for detecting opened and closed positions of the slips. Load sensors are associated with the slips for detecting load status of the slips. A control system receives input signals from the sensors, and confirms that either the traveling slips or the stationary slips are loaded before releasing or allowing the release the opposing set of slips, when transferring the pipe string load from the one set of slips to the other set of slips.

  • Publication number: 20150013975
    Abstract: A method and system for monitoring a cable within a coiled tubing is disclosed. A first set of excitation signals is applied to the coiled tubing at a first point in time. The first set of excitation signals comprises one or more signals applied at one or more depths. The cable is positioned at a first location within the coiled tubing at the first point in time. A signal corresponding to the first set of excitation signals is detected at one or more fiber optic lines associated with the cable and location of the cable within the coiled tubing is determined using the detected signal corresponding to the first excitation signal.

  • Publication number: 20140374092
    Abstract: An electro-mechanical indicator system for signaling when a droppable object (such as, for example, a dart, plug or ball) is released during well cementing operations. A body section has first and second chambers divided by a fluid and pressure sealing barrier. A mechanical trigger mechanism is situated in the first chamber, which is exposed to elevated pressures and harsh wellbore fluids. Less robust components, such as sensor(s), power source(s), and signal device(s) located in the second chamber, remain isolated from the wellbore environment and elevated pressures.

  • Patent number: 8915296
    Abstract: Disclosed is an apparatus for setting an anchor in a borehole and milling a window in a side surface of the borehole in a single trip. The apparatus includes a mechanically-settable anchor initially forming part of the drill string, a plug member position below the anchor, and a milling assembly. When the drill string reaches a desired depth in the wellbore, the plug member may be activated from the surface, thus setting the plug member in position with respect to the wellbore. The anchor has an activation element which, when contacted in a predetermined manner, sets the anchor. The plug member has an operation element adapted so that, when the anchor and plug member come into contact with one another in a predetermined orientation, the activation element is operated by the operation element, thus setting the anchor.

  • Patent number: 8899322
    Abstract: Autonomous control of a wellbore tool is provided by programming a memory module of a processor with a database having data relating to a selected parameter of interest; conveying a sensor and the processor along the wellbore; and activating the wellbore tool if the processor determines that a measurement provided by the sensor correlates with the database data. The processor may correlate the sensor measurements with a predetermined pattern associated with the data, a preset value, and/or a preset range of values. Well tool activation may occur when the processor finds: a substantial match between a predetermined pattern and at least one measured value; a present value and at least one measured value, and/or a preset range of values and at least one measured range of values. Also, activating the well tool may occur only if a measurement from a second sensor meets a preset criteria.

  • Publication number: 20140345858
    Abstract: An apparatus for manipulating objects include a plurality of actuators distributed on a rig. The actuators cooperate to orient and move the well equipment. Each actuator may include at least one non-rigid tension member configured to engage the well equipment, and at least one sensor generating a signal representative of at least one parameter of: (i) a length of at least one of the at least one non-rigid tension members, (ii) a tension along at least one of the at least one non-rigid tension members, (iii) a position of at least one of the at least one non-rigid tension members; and (iv) an orientation of at least one of the at least one non-rigid tension members. The actuators may also each include a drum guiding each of the at least one non-rigid tension members and a motor rotating each drum. The apparatus further includes a controller in communication with the actuators, the controller being programmed to move the object based on the at least one sensor signals.

  • Patent number: 8884778
    Abstract: Apparatus and methods for controlling and communicating with one or more tools in a downhole tool string including a tractor, an auxiliary tractor tool, a logging tool, a safety sub, a release mechanism, a unit containing sensors for monitoring downhole conditions, a setting tool, and a perforating gun. Also provided are apparatus and methods for controlling and communicating with one or more perforating guns, release devices, and explosive devices in a string to be lowered into a wellbore. Control and communication are accomplished by sending signals from the surface to control switches in the control units on the tool, with redundant switches for safety, to state machines in the respective control units, “each state machine returning a signal verifying switch status to the surface. Control and power functions are accomplished with voltage of different polarities for safety.

  • Patent number: 8875785
    Abstract: A method of correcting a downhole speed of a tool string moving in a wellbore. In some implementations, the method includes obtaining a downhole tool speed with an accelerometer, moving the tool string past at least two casing collars, calculating the average tool speed over the interval between collars, and comparing the downhole tool speed as calculated using the data from the accelerometer to the average tool speed calculated based on the time and the interval between the casing collars, determining a correction factor, and determining a corrected downhole tool speed. A system includes a casing collar locator, an accelerometer, and a processor adapted to compare the downhole tool speed calculated using data from the accelerometer to the average downhole tool speed calculated using the time and casing collar location, determine a correction factor and determine a corrected downhole tool speed.
