  • Surface seismic profile system and method using vertical sensor
    Patent number: 5581514
    Abstract: The seismic profile system and method using vertical sensor arrays relate to obtaining a seismic profile under two highly reflective boundaries. The system includes a source of seismic energy disposed beneath the air/water boundary, a first pair of sensors arranged in vertical relation and spaced apart by a predetermined vertical spacing distance, and a second pair of sensors similarly situated and spaced from the first pair by a predetermined horizontal spacing distance. The first and second pairs of sensors are disposed below at least two highly reflective boundaries, which may be the air/water boundary and a mud/water boundary. According to the method, the source is moved between two points and data is collected from the first and second pairs of sensors.
