Abstract
A seismic receiver may acquire seismic data reflected from one or more subterranean features of the Earth. The seismic receiver may include a housing and a four-component sensor that may measure four properties of a seismic wavefield. The four-component sensor may be disposed within the housing. The seismic receiver may also include a particle motion sensor that may measure a particle motion of the seismic wavefield in at least one direction. The particle motion sensor may be disposed within the housing, such that the four-component sensor and the particle motion sensor are separated by a distance in a first direction.
Claims20
A seismic receiver configured to acquire seismic data reflected from one or more subterranean features of the Earth, comprising:
- a housing;
- a four-component sensor configured to measure four properties of a seismic wavefield, wherein the four-component sensor is disposed within the housing;
- and
- a particle motion sensor configured to measure a particle motion of the seismic wavefield in at least one direction, wherein the particle motion sensor is disposed within the housing, and wherein the four-component sensor and the particle motion sensor are separated by a distance in a first direction.
A seismic receiver configured to acquire seismic data reflected from one or more subterranean features of the Earth, comprising:
- a housing;
- a four-component sensor configured to measure four properties of a seismic wavefield at a first location, wherein the four-component sensor is disposed within the housing;
- a first pressure sensor configured to measure a first pressure of the seismic wavefield at a second location different from the first location, wherein the first pressure sensor is disposed within the housing, and wherein the four-component sensor and the first pressure sensor are separated by a distance in a first direction;
- and
- a second pressure sensor configured to measure a second pressure of the seismic wavefield at a third location different from the second location.
A seismic receiver configured to acquire seismic data reflected from one or more subterranean features of the Earth, comprising:
- a housing;
- a four-component sensor configured to measure a first particle motion of a seismic wavefield in three directions and a pressure of the seismic wavefield, wherein the four-component sensor is disposed within the housing;
- a first particle motion sensor configured to measure a second particle motion of the seismic wavefield in at least one of the three directions, wherein the first particle motion sensor is disposed within the housing, and wherein the four-component sensor and the first particle motion sensor are separated by a first distance;
- and
- a second particle motion sensor configured to measure a third particle motion of the seismic wavefield in the at least one of the three directions, wherein the second particle motion sensor is disposed within the housing, and wherein the four-component sensor and the third particle motion sensor are separated by a second distance.
