Seismic data processing using one or more non-linear stacking enabling detection of weak
signals relative to noise levels. The non-linear stacking includes a double phase, a double …

The invention provides a method of determining the orientation of a seismic receiver (4, 6)
from seismic data acquired at the receiver (4, 6). The determined orientation can be taken …

Three-axis velocity data, obtained along with pressure data in a marine seismic survey, are
rotated to a ray direction. Plane wave decomposition is applied in the ray direction to the …

Method is provided for determining the orientation or horizontal geophones used in marine
seismic surveying. First-arrival signals are processed by rotating a coordinate system …

A system and method of processing seismic data obtained using a plurality of towed single-
component receivers in a marine environment is described, the towed single-component …

A system and method of acquiring and processing full elastic waveform data from a vertical-
force source comprises providing seismic waves into the earth from the vertical-force source …

A system and method of processing seismic data obtained using a surface-based receiver
configured to measure vertical movement of the Earth includes retrieving seismic data from a …

Disclosed herein are systems and methods for calibrating seismic data using seismic
attribute pairs such as amplitude versus offset (AVO) attributes. In one embodiment, a …

Measurement data acquired by at least one sensor in a cable structure towed through a
body of water is received. A tor sional vibration noise component in the measurement data is …

A system for, and method of, orienting seismic energy sources and seismic energy receivers
to substantially separate a compressional wave from a vertical shear wave. The method …
