  • Patent number: 9835026
    Abstract: A method for transmitting data from a downhole tool to a surface location includes running a downhole tool into a wellbore. The downhole tool includes a pressure sensor. An annulus pressure in the wellbore is measured at a first time, using the pressure sensor, to produce a first pressure measurement. The first pressure measurement is compressed to produce a reference sample. The reference sample is transmitted to the surface location. The annulus pressure in the wellbore is measured at a second time, using the pressure sensor, to produce a second pressure measurement. A difference between the first pressure measurement and the second pressure measurement is determined to produce a first delta pressure measurement. The first delta pressure measurement is compressed to produce a first compressed delta pressure measurement. The first compressed delta pressure measurement is transmitted to the surface location.

  • Patent number: 9835021
    Abstract: Drilling system and methods may employ a weight-on-bit optimization for an existing drilling mode and, upon transitioning to a different drilling mode, determine an initial weight-on-bit within a range derived from: a sinusoidal buckling ratio, a helical buckling ratio, and the weight-on-bit value for the prior drilling mode. The sinusoidal buckling ratio is the ratio of a minimum weight-on-bit to induce sinusoidal buckling in a sliding mode to a minimum weight-on-bit to induce sinusoidal buckling in a rotating mode, and the helical buckling ratio is the ratio of a minimum weight-on-bit to induce helical buckling in the sliding mode to a minimum weight-on-bit to induce helical buckling in the rotating mode. The ratios are a function of the length of the drill string and hence vary with the position of the drill bit along the borehole.

  • Patent number: 9822637
    Abstract: A message to be sent from a downhole tool in a wellbore is modulated into a data uplink signal of pressure variations in the drill string. The pressure variations are generated by varying the torque on the rotor of the generator by varying the electric load on the generator. The pressure variation sequence of the data uplink signal may be selected from a look up table of known sequences. The message may be received by a surface receiver using one or more pressure sensors. The message may be demodulated from the detected pressure data using digital and analog signal processing. The frequency of the data uplink signal may be selected based in part on detected noise in the wellbore. The data uplink signal may be modulated using a spread spectrum protocol.

  • Patent number: 9816325
    Abstract: The present disclosure relates to a power isolation adapter which can enable the use of multiple power sources in a bottom hole assembly (BHA) by isolating the power sources on a tool bus while maintaining a communication bus across the BHA. Such power sources may be part of a measurement-while-drilling (MWD) module, such as a mud turbine generator, providing power as a DC signal. The power isolation adapter isolates the power sources by blocking DC signals, but maintains an AC communication bus across the BHA. The ability to use multiple power sources in a BHA thus allows for more complex BHA configurations that normally could not be powered using a single power source.

  • Patent number: 9745843
    Abstract: The method and system for determining position with improved calibration allows a device to initiate activity at the proper location, such as navigating a drill bit through a rock formation. A position sensor having an oscillation element with a range of displacement in a set direction according to gravity generates a position data signal based on an amount of displacement in the set direction. A temperature sensor detects temperature and duration of the temperature. A plastic bias value is determined by a processor module based on the temperature data signal, the duration of the temperature, and the position data signal so as to account for bias and hysteresis errors. A position value is set according to the plastic bias value so that the position value is more accurate. The activity of the terminal device is initiated or maintained according to the position value calibrated by the plastic bias value.

  • Patent number: 9482085
    Abstract: A system and method are provided for providing electromagnetic (EM) measurement-while-drilling (MWD) telemetry capabilities using an existing mud-pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal that mimics a mud-pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the signal into the existing pulse tool receiver. Since the EM signal mimics a mud-pulse signal, the pulse tool receiver does not require software or hardware modifications in order to process an EM telemetry mode. The EM tool can be adapted to also provide dual telemetry by incorporating a conventional pressure pulser that would normally be used with the pulse tool.

  • Patent number: 9472990
    Abstract: Systems and methods for insulating the Y-points of three-phase electric motors commonly used in ESP systems, in which the Y-points are not grounded or tied to a reference voltage, and may consequently experience high voltages. One embodiment is an apparatus for insulating the Y-point of the motor using an electrically insulating enclosure. The enclosure has apertures that extend from a cavity therewithin the to the exterior of the enclosure. The cavity accommodates the Y-point of the motor. The conductors which are connected at the Y-point junction extend from the cavity to the coils of the three-phase motor, and possibly to an instrument package. Seals are formed at the apertures to provide an electrically insulating barrier between the Y-point and the exterior of the enclosure. The cavity may be filled with an insulating material such as potting compound or oil.

  • Patent number: 9279903
    Abstract: An apparatus for measuring the bending on a drill bit operating down hole in a well may comprise at least three pockets circumferentially spaced equidistantly around the drill collar of the drill string to which the drill bit is attached. Four strain gauges are equidistantly circumferentially spaced around each of the pockets so as to form first and second sets of strain gauges. The strain gauges in the first set are connected into one Wheatstone bridge while the gauges in the second set are connected in a second bridge. Each of the strain gauges that are oriented similarly within each of the pockets are connected in series within a single leg of a bridge so that the output voltage of the bridge is unaffected by bending in the drill string. The output of first bridge is used to determine the bending on the drill bit.
