  • Patent number: 11352871
    Abstract: Apparatus and operational methods thereof, including a top drive, a rotation sensor, and a processing device. The top drive connects with an upper end of a drill string. The rotation sensor facilitates rotational distance measurements indicative of rotational distance achieved by the top drive. The processing device causes the top drive to impart rotational oscillations alternatingly in opposing directions to the upper end of the drill string while maintaining a downhole toolface orientation during a slide drilling operation, such that each rotational oscillation rotates the upper end of the drill string through a base rotational distance. The processing device also causes the top drive to change the downhole toolface orientation by an offset rotational distance by adding the offset rotational distance and an overshoot rotational distance to the base rotational distance of an instance of the rotational oscillations.

  • Patent number: 10968713
    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: 10316620
    Abstract: A system for selectively actuating sliding valves includes a segmented sleeve exhibiting a rocking (or pivoting) function. The rocking allows the bottom end of the sleeve to open wider when the front of a dart is pressed against it, provided the length of the dart is shorter than a “target length” determined by the sleeve geometry. When the dart is at least as long as the “target length” of the sleeve, the back of the dart prevents the sleeve from rocking as the front of the dart is pressed against the bottom seat. The dart remains pressed against the sleeve, effectively isolating the wellbore section above the dart from the one below it. Multiple zones can thus be independently isolated by using a set of sleeves with similar diameters, but different “target lengths.

  • Patent number: 10101483
    Abstract: Systems and methods for evaluating a cement installation are provided. In one example, the cement may be evaluated using a casing arrival measurement sensor that measures casing arrival signals resulting from firing a signal from a cement bond logging acoustic source. External signals (e.g., signals other than the casing arrival signals) may be attenuated by firing an attenuation firing signal.

  • Publication number: 20180252056
    Abstract: Maximum penetration of coiled tubing in extended reach horizontal wellbores is significantly increased by using a continuously tapered portion of coiled tubing. In particular, the tubing wall thickness is continuously tapered such that the well thickness gradually decreases toward the far end of the coiled tubing. The exterior dimension remains constant while the internal diameter gradually increases. The non-linear thickness profile of the tubing is optimized for extended reach in horizontal wellbores. In some cases, the thickness profile is optimized for providing a uniform axial strain on the tubing in the horizontal section of the well.

  • Patent number: 10030456
    Abstract: A method for extending reach of a coiled tubing string in a deviated wellbore includes determining a frequency of vibration of the tubing string based on a function of the bending resonance of the tubing string and vibrating the tubing string at the determined frequency while the tubing string is inside the wellbore. Embodiments may also include a non-transitory computer-readable storage medium to execute the foregoing method and a system for extending reach of a coiled tubing string in a deviated wellbore.

  • Publication number: 20180003846
    Abstract: A technique facilitates removal of noise from sonic logging signals. The technique may comprise various approaches used alone or in combination to reduce or eliminate noise associated with tool arrival. The technique may comprise an active cancellation approach which optimizes the cancellation effect while having minimal impact on the desired acoustic signals. The techniques also may utilize an asynchronous noise cancellation approach with a calibration transmitter designed to minimize impact on the desired acoustic signals.

  • Publication number: 20170342976
    Abstract: A valve and seal arrangement for extended life in a positive displacement pump. The arrangement may take on different configurations. The seal may be secured within a shielding sidewall of a valve head for isolation from differential pressure during striking of the valve head at a valve seat. Additionally, the seal itself may include an axial tail for sealing off the fluid chamber below and defined by the seat prior to the striking of the valve head at the seat. Further, a horizontal flange defining a clearance of no more than about a layer of an abrasive constituent of a slurry being pumped may be utilized. That is, as opposed to, or in addition to, sealing in advance of striking, flow may be reduced to no more than a constituent layer thickness in advance of the striking. Other similarly advantageous architectural valve features may also be employed.

  • Patent number: 9803462
    Abstract: Techniques for axial vibration control of wireline tools and cables during logging operations. In undesirable cases the axial vibrations may lead to or exasperate the stick-slip problems of the logging tool. Control systems and strategies to minimize vibrations and techniques for identifying and inhibiting the sticking of the cable. A system includes a surface actuator and a sensor. The actuator generates an axial wave on the wireline cable which travels down the cable. If there is sticking of the cable, a reflection can also occur at the location of sticking. This shift in the transmission of the wave on the wireline cable is used to identify the onset and/or presence of sticking.

  • Patent number: 9659113
    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.
