  • Patent number: 10605599
    Abstract: A gradient sensor device includes a support structure providing a surface, and at least three particle motion sensors coupled with and/or arranged on the support structure to measure translational data in a first direction. The particle motion sensors have an arrangement that enables calculation of a spatial gradient of the translational data in a second direction different from the first direction.

  • Patent number: 10094944
    Abstract: Separating survey data for multiple survey sources where first survey data along a first axis measured by a survey sensor device is received, the first survey data responsive to activations of the plurality of survey sources at respective azimuths with respect to the survey sensor device. Second survey data is rotated towards a first azimuth of a first of the plurality of survey sources. The rotated second survey data is used as a model of interference caused by a subset of the plurality of survey sources excluding the first survey source. In other examples, a time dithering technique is performed to separate survey data for multiple survey sources.

  • Patent number: 10048395
    Abstract: A seismic sensor device includes an elongated housing for placement at least partially into an earth surface. A plurality of particle motion sensors are contained in the elongated housing to measure translational data in a first direction, where plural pairs of the particle motion sensors are spaced apart along a second, different direction along a longitudinal axis of the elongated housing. A communication interface communicates the measured translational data to a computer system configured to compute a gradient based on respective differences of the measured translational data of the corresponding plural pairs of the particle motion sensors, and compute one or more of rotation data and divergence data using the gradient.
