  • Patent number: 8340911
    Abstract: A compensated ensemble crystal oscillator clock system. The clock system includes preferably four quad compensated clocks, a compensated temperature sensor, and software for processing and correcting system response. Physical fabrication of elements of the quad compensated clocks, the compensated temperature sensor and cooperating software minimized drift in frequency of the oscillator clock system in harsh borehole environments encountered while drilling a borehole. The clock system exhibits a frequency stability of 2.8×10?9 or less over a temperature range of from 0° C. to 185° C. The compensated ensemble crystal oscillator clock system is particularly applicable to seismic-while-drilling operations wherein precise downhole measurements of time are required typically over a period of days.

  • Patent number: 7916578
    Abstract: A vibration source (10) includes an armature bar (12) having a major length dimension, and a driver (20A) positioned about the armature bar. The driver (20A) is movably coupled to the armature bar (12), and includes an electromagnet (40). During operation the electromagnet (40) is activated such that the driver (20A) moves with respect to the armature bar (12) and a vibratory signal is generated in the armature bar. A described method for generating a vibratory signal in an object includes positioning the vibration source (10) in an opening of the object, coupling the armature bar (12) to a surface of the object within the opening, and activating the electromagnet (40) of the driver (20A) such that the driver moves with respect to the armature bar (12) and a vibratory signal is generated in the armature bar and the object.

  • Patent number: 7841403
    Abstract: An apparatus for rotating an instrument in a wellbore includes a non magnetic housing configured to traverse the interior of the wellbore. The housing has an external diameter smaller than an internal diameter of a casing disposed in the wellbore. A plurality of electromagnets is arranged circumferentially about the interior of the housing and is configured to induce magnetic flux through a wall of the housing when actuated. A controller configured to sequentially rotationally actuate the electromagnets. A method for rotating a wellbore instrument in a wellbore includes causing parts of an instrument housing to be sequentially rotationally magnetically attracted to a casing disposed in the wellbore. The housing has a smaller external diameter than an internal diameter of the casing. The sequential rotational magnetic attraction is continued as needed.

  • Patent number: 7230543
    Abstract: Geophysical measurement system employed during the drilling of a well borehole. The system employs a reference clock disposed within equipment at the surface of the earth and a borehole assembly which houses a downhole clock and at least one sensor. The borehole assembly is operationally connected to a drill string, which advances the borehole. At least one synchronization shuttle apparatus containing a shuttle clock is conveyed downhole to the borehole assembly to synchronize the borehole clock with the reference clock. Reference and borehole clock synchronization is maintained at one millisecond or less over a period of days. Outputs from the reference clock and borehole clock and sensor are combined to obtain a measure of a geophysical parameter of interest. Although the measurement system is particularly applicable to seismic-while-drilling measurements, it can be used in a wide variety of clock driven geophysical measurements.
