The casing while drilling system is adapted to advance a bottom hole assembly into a subsurface formation via a casing. The communication system comprises a high frequency modulator and a transducer. The modulator is positioned in the bottom hole assembly and adapted to generate a mud pulse by selectively restrict mud flow passing therethrough. The transducer is adapted to detect the mud pulse generated by the modulator. | 11-13-2008 |
20090095490 | Electrically activating a jarring tool - A method of using jarring tool in a wellbore, where the jarring tool is electrically activated to apply an impact force transmitted to at least another tool in the well. The method may further comprise operating a hydraulic mechanism in response to electrical activation of the jarring tool to cause a first member of the jarring tool to be moved to collide with a second member of the jarring tool to apply the impact force. Also, the method may involve electrically activating the jarring tool by communicating at least one command over at least one electrical conductor to the jarring tool. | 04-16-2009 |
20100018770 | System and Method for Drilling a Borehole - A technique facilitates drilling in a wide variety of applications and environments. The technique utilizes a coiled tubing bottom hole assembly constructed with a sensor system that provides the ability to steer a borehole within a reservoir. An orienter is connected to a top end of the bottom hole assembly to provide rotational movement of the bottom hole assembly. The orienter can be designed to provide continuous and bidirectional rotational movement of the coiled tubing bottom hole assembly.

20140084696 | System And Method For Power Transmission In A Bottom Hole Assembly - Various embodiments of methods and systems for wireless power and data communications transmissions to a sensor subassembly below a mud motor in a bottom hole assembly are disclosed. In a certain embodiment, a float valve is located above the motor. Power is supplied by a turbine or by batteries located in a subassembly above the float valve. Wires pass through the float valve and connect to an annular coil. Power is transmitted through the annular coil to an inductively coupled second, mandrel coil that is attached to the rotor. By leveraging resonantly tuned circuits and impedance matching techniques for the coils, power can be transmitted efficiently from one coil to the other despite relative movement and misalignment of the two coils. | 03-27-2014 |
20140084946 | System And Method For Wireless Power And Data Transmission In A Rotary Steerable System - Various embodiments for wireless power and data communications transmissions between a cartridge in a rotary steering system and components within a drill collar are disclosed. In a certain embodiment, magnetic fields are used to transfer power and data between the cartridge of a rotary steering system and electronics and/or sensors mounted in the drill collar. A first coil is attached to the pressure housing of the cartridge by a shaft containing wires. The turbine in the pressure housing provides an alternating current to the first coil, which is attached to the shaft. Consequently, the first coil generates an alternating magnetic field that passes through the ferrite surrounding a second coil that is attached by wires to an annular pressure housing that is attached to the drill collar. The alternating magnetic field generates an emf in the second coil, which provides power for electronics and sensors mounted in the drill collar. | 03-27-2014 |
