Abstract
A method can include receiving information associated with an interface between a first medium and a second medium where the information includes sensor data; based on at least a portion of the information, estimating wave properties that include elastic properties, depth-dependent properties and horizontal slowness; and, based on the estimated wave properties, calculating an orientation of a sensor utilized to acquire at least a portion of the sensor data.

A method to calculate an orientation of a multicomponent seismic sensor comprising:
- receiving information associated with an interface between a first elastic medium and a second elastic medium wherein the information comprises sensor data acquired by the multicomponent seismic sensor;
- based on at least a portion of the information, estimating seismic wave properties that comprise elastic properties, depth-dependent properties and horizontal slowness, wherein the depth-dependent properties are determined by:
- calculating vertical slowness in the first elastic medium;
- estimating a polarization angle of an incident seismic wave in the first elastic medium corresponding to the calculated vertical slowness;
- and
- calculating an angle of incidence in the second elastic medium;
- and
- based on the vertical slowness in the first elastic medium, the polarization angle of the incident seismic wave in the first elastic medium, and the angle of incidence in the second elastic medium, calculating an orientation of the multicomponent seismic sensor.
A system comprising:
- a processor;
- memory operatively coupled to the processor;
- and
- processor-executable instructions stored in the memory to instruct the system to:
- receive information associated with an interface between a first elastic medium and a second elastic medium wherein the information comprises sensor data acquired by a multicomponent seismic sensor;
- based on at least a portion of the information, estimate seismic wave properties that comprise elastic properties, depth-dependent properties and horizontal slowness, wherein the depth-dependent properties are determined by:
- calculating vertical slowness in the first elastic medium;
- estimating a polarization angle of an incident seismic wave in the first elastic medium corresponding to the calculated vertical slowness;
- and
- calculating an angle of incidence in the second elastic medium;
- and
- based on the vertical slowness in the first elastic medium, the polarization angle of the incident seismic wave in the first elastic medium, and the angle of incidence in the second elastic medium, calculate an orientation of the multicomponent seismic sensor.
One or more non-transitory computer-readable storage media comprising processor-executable instructions to instruct a computing system to:
- receive information associated with an interface between a first elastic medium and a second elastic medium wherein the information comprises sensor data acquired by a multicomponent seismic sensor;
- based on at least a portion of the information, estimate seismic wave properties that comprise elastic properties, depth-dependent properties and horizontal slowness, wherein the depth-dependent properties are determined by:
- calculating vertical slowness in the first elastic medium;
- estimating a polarization angle of an incident seismic wave in the first elastic medium corresponding to the calculated vertical slowness;
- and
- calculating an angle of incidence in the second elastic medium;
- and
- based on the vertical slowness in the first elastic medium, the polarization angle of the incident seismic wave in the first elastic medium, and the angle of incidence in the second elastic medium, calculate an orientation of the multicomponent seismic sensor.
