Abstract
A seismic cable for use in land applications is described. The cable includes seismic sensors for measuring seismic signals reflected from subterranean or subsea formations. The cable may be deployed in trenches dug in the survey region to provide adequate sensor coupling to ground. Sensor units may be inline with the cable and may further be disposed in slim casings, thus facilitating handling and deployment.
Claims26
A method for land-based seismic surveying, comprising:
- providing a seismic cable having a plurality of sensor units integrated into the cable, at least some of the sensor units having multi-component sensors disposed therein;
- forming a trench in a terrain of interest;
- deploying the sensor units into the trench;
- and
- using the sensor units to record seismic data.
A seismic cable for land-based seismic surveying, comprising:
- a plurality of sensor units integrated into the cable such that the sensor units are in-line with the cable;
- and
- a multi-component sensor disposed in the sensor unit.
