    Abstract: A downhole tool for incorporation in a drill pipe for selective operation of the tool from surface level when the tool is in a wellbore. The tool comprises a controller electrically powered by a power source separate from surface level, a first sensor of the controller to detect a dynamic variable of the tool in the wellbore and produce an output signal dependent thereon; a second sensor of the controller to detect a mechanical signal transmitted from an operator at surface level; a motor driven by the power source under the control of the controller when said mechanical signal is received; and an actuator driven by the motor to actuate the tool; wherein the controller switches between at least two states in response to changes in said dynamic variable, only in said second state the controller being receptive to said mechanical signal from the operator to drive the motor. The tool may be a disconnect device and/or a circ sub.

  • Patent number: 10352155
    Abstract: An electromagnetic (EM) telemetry system with telluric referencing for use with downhole equipment is described. Embodiments of an EM telemetry system with telluric referencing include a downhole transceiver comprising an encoded signal transmitter, a downhole sensor disposed to monitor the downhole equipment, the downhole sensor coupled to the transceiver, an encoded signal receiver, a reference receiver spaced apart from the encoded signal receiver and communicatively coupled to the encoded signal receiver, and a telluric voltage module coupled to one of the encoded signal receiver and the reference receiver. The telluric voltage module is communicatively coupled to the encoded signal receiver and the reference receiver to receive an encoded signal and a reference signal, respectively, which may include telluric noise. The telluric voltage module synchronizes the encoded signal and the reference signal, subtracts the reference signal from the encoded signal, and outputs a signal free from telluric noise.

  • Patent number: 10240409
    Abstract: A power tong positioner has one or more eddy current probes mounted in association with a power tong/backup unit. An electric current runs through the probe, and with the probe positioned close to a tubular connection, movement of the probe along the length of the connection, with the electric field encompassing surface features on the tubular, will cause a change in the electrical impedance (conductivity) which enable identification of the connection seam or other defined attributes (the “target” attributes). The power tong/backup unit can be positioned accordingly. A portfolio of profiles of non-connection seam surface features of different tubular connections may be generated, stored in a database, and accessed by the system, which enables identifying the connection seam/face with greater accuracy. Other attributes of the invention include storing profile information on RFID tags, and storing and accessing tubular information from a cloud server or other form of remote database.

  • Publication number: 20150122479
    Abstract: Among other things, there are disclosed embodiments of devices, suitable for incorporation into well-logging tools, for the in situ measurement of the acoustic impedance of a fluid in the well bore, such as drilling mud. The device includes a sonic emitter that emits sonic pulses into a solid probe. The pulses are partially transmitted and partially reflected at opposite surfaces, and the decay of the amplitude of successive sonic pulses is used to determine the acoustic impedance of the fluid.

  • Publication number: 20150122488
    Abstract: A method is disclosed in which an electrical conductivity of a treatment fluid is measured with one or more sensor at various instants of time. The method is further performed by generating one or more signals indicative of the electrical conductivity of the treatment fluid and transmitting the one or more signals to a computer system. The method is further performed by analyzing the one or more signals to determine a phase change in the treatment fluid based upon a positive or negative change in the electrical conductivity of the treatment fluid from a predetermined electrical conductivity range.

  • Publication number: 20150114626
    Abstract: An object launching apparatus for a well has a housing, a flow mandrel, and a cage. The flow mandrel is disposed in the housing's internal chamber, and a flow passage in the mandrel communicates flow from the housing's inlet to the mandrel's flow port, which in turn communicates with the housing's outlet. The cage is disposed in the internal chamber and defines pockets for holding the objects. A motor and shaft move the cage in the housing relative to the mandrel's flow port so the cage's pockets can be selectively positioned in communication between the mandrel's flow port and the housing's outlet. This allows any of the object(s) held in the positioned pocket to be launched into the flow to the well. Preferably, the motor rotates the shaft so the cage can ride linearly along the shaft's thread and the cage can rotate through a cammed engagement with the housing.

  • Patent number: 9004156
    Abstract: A sensor assembly for detection of fluid flow signaling over a tubular conveyance. The assembly may be employed for activation of a variety of different downhole actuators such as firing heads for perforating guns or hydrostatic set modules for packer deployment. The assembly is configured with a flow translation device which is disposed in a manner exposed to fluid flow directed through an oilfield tubular coupled to the assembly. Thus, a detector coupled to the translation device may obtain mechanical data from the device which is reliably indicative of the flow, irrespective of the physical nature of the flow itself. As such, enhanced reliability for subsequent actuator firing based on the flow signaling may be achieved.
