Abstract: A system and method are described herein for generating a frequency sweep signal set for use in seismic data gathering. Low frequency sweep rate modifications are combined to compensate for vibrator limitations and vibrator far-field responses with high frequency sweep rate modifications to compensate for absorption, and then the frequency sweep signal set is generated based on the combination of high and low frequency sweep rate modifications.

Abstract: Method and retrievable vertical hydrophone cable for collecting seismic data underground. The retrievable vertical hydrophone cable includes an envelope having a first end at which a connector mechanism is provided to close the envelope; plural hydrophones distributed inside the envelope at predetermined positions; and a fluid provided inside the envelope and around the plural hydrophones. The envelope increases its volume when the fluid is pressurized through the connector mechanism.

Abstract: A method and a mechanized system for deploying plural geophones underground for collecting seismic data. The mechanized system includes a vehicle configured to travel above ground and having a storage area that stores the plural geophones; a digging mechanism attached to the vehicle and configured to dig a trench when in contact with the ground; and a damping mechanism attached to the vehicle and configured to hold a geophone behind the digging mechanism relative to a traveling direction (X) of the vehicle.
