Abstract: Methods and systems output at least one drill string whirl attribute, such as magnitude, orientation, velocity and type, without requiring determination of whirl frequency. Transforming acceleration data into drill string motions provides a path of one point along the drill string. Fitting these motions throughout one complete revolution of the drill string to a revolution ellipse, for example, provides revolution ellipse centers defining centers of rotation for each revolution fitted. A whirl ellipse, for example, derives from another fitting using a plurality of the revolution ellipse centers. Coefficients from the whirl ellipse and/or vector direction of the centers provide at least one whirl attribute for output.

Abstract: A method of performing notch compensation and a system to perform notch compensation for a first seismic streamer are described. The method includes disposing the first seismic streamer at a first depth, where the seismic streamer includes a first set of sensors to receive reflections resulting from a seismic source, the reflections indicating a notch at a frequency. The method also includes disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer including a second set of sensors to receive reflections resulting from the seismic source. The method further includes processing the reflections received by the first set of sensors and the second set of sensors together to derive the match filter, and applying the match filter to the reflections received by the first set of sensors of the first seismic streamer to compensate for the notch.

Abstract: Systems and methods compute dysfunctions via mapping of tri-axial accelerations of drill pipe into drill-string motions. The methods remove gravitational and centripetal accelerations to yield corrected acceleration data due to the vibration only, transform the corrected acceleration data, and maps resulting transformed acceleration data into continuous drill-string positions. The maps provide 2D/3D visualization of drill-string motions to enable real-time optimization and control of well drilling operations and other scenarios where proactive detection of temporal events in automated systems may aid in avoiding failures.

Abstract: The invention relates to a method, system and apparatus for synchronizing the time of time series data acquired from a wellbore sensor relative to a reference time series. This comprises acquiring a first time series from a sensor in a wellbore, acquiring a reference time series and determining a linear moveout time correction to apply to the first time series. The linear moveout time correction is equal to the depth of the wellbore sensor divided by the signal propagation velocity. The linear moveout correction is applied to the first time series. The first time series is cross-correlated with the reference time series to determine a cross-correlation time correction to apply to the first time series and the cross-correlation time correction is applied to the first time series to obtain a cross-correlation corrected time series. Dynamic time warping and dynamic cross-correlation may be used to adjust for clock drift.
