摘要： Methods for drilling a new well in a field having a plurality of existing cased wells using magnetic ranging while drilling are provided. In accordance with one embodiment, a method of drilling a new well in a field having an existing cased well includes drilling the new well using a bottom hole assembly (BHA) having a drill collar having by an insulated gap, generating a current on the BHA while drilling the new well, such that some of the current passes through a surrounding formation and travels along a casing of the existing cased well, measuring from the BHA a magnetic field caused by the current traveling along the casing of the existing cased well, and adjusting a trajectory of the BHA to avoid a collision between the new well and the existing cased well based on measurements of the magnetic field.

摘要： A method for drilling a well includes applying a current across a drill collar that surrounds an internal magnetometer. The current travels across the drill collar and along one or more other current paths to return to the drill collar. The method also includes using the magnetometer to measure magnetic fields due to the current being applied across the drill collar and the current across one or more other current paths while the drill collar is disposed at a first angle of rotation and rotating the drill collar to a second angle of rotation. The method further includes measuring the magnetic fields using the internal magnetometer while the drill collar is disposed at the second angle of rotation and determining a relationship between the current across the drill collar and a portion of the magnetic fields due to the current across the drill collar measurable by the internal magnetometer.

摘要： A three dimensional ornament is provided that is configured to be suspended from a tether and rotate to provide the appearance of different shapes as the ornament rotates. The ornament comprises a frame construction with an open interior and a frame member perimeter. An upper apex affixes to a swivel joint and is aligned with the lower apex of the ornament along the ornament centerline. The centerline of the ornament separates the left side from the right side of the ornament, whereby the frame members and corresponding connecting apexes of the frame member periphery are mirror images of one another across the centerline of the ornament. As the ornament spins, it projects a changing image from an onlooker's perspective, which changes throughout the ornament rotation and based on the rotation speed thereof.

摘要： Digital methods and systems for signal processing and filtering are provided. The methods and corresponding systems provide asynchronous conversion of sampling rate frequencies and utilize advanced multistage phasor filters for converting an input signal having a first sampling rate into an output signal sampled in an arbitrary sequence of sampling times. The conversion process provides a sequence of sets of complex numbers representing a filtered version of the input signal. More specifically, the conversion process includes the calculation of values of the output signal by multiplying (e.g., scaling) the sets of complex numbers by a corresponding set of complex phasors, the complex phasors corresponding to the timing of the arbitrary time sequence to obtain a corresponding set of real results with the value of the output signal being the sum of the real results.

摘要： Background audio can be provided during telephonic communication. Telephonic communication can be established via a network, such as between a user of a telephony device and a communication partner having a second telephony device. A voice signal may be received from the user via a microphone integral with the telephony device. An audio track can be retrieved, for example, from memory integral with the telephony device or from a third-party service provider via the communications network. Noise reduction is performed on the voice signal to produce a clean voice signal. The clean voice signal may be combined with the audio track to produce a combined signal, such that the audio track provides background audio to the clean voice signal. The combined signal can then be transmitted from the telephony device to the second telephony device via the communications network.

摘要： A system and methodology provide improved control over the directional drilling of a wellbore while enabling additional functionality. A rotational valve is mounted within a drill collar of a rotary steerable system to control flow of actuating fluid to one or more steering pads which are selectively moved in a lateral direction with respect to the rotary steerable system. The rotational valve also is controlled to carry out at least one additional function while controlling the direction of drilling.
