Method of acquiring near offset and zero offset seismic data

摘要

A method for seismic data acquisition includes deploying a seismic energy source at a selected position above an area of the Earth's subsurface to be evaluated. A substantially zero offset sensor is disposed proximate the seismic energy source. A plurality of seismic sensors is deployed proximate the area. At selected times the seismic energy source is actuated. Signals detected by the seismic sensors and the substantially zero offset sensor are recorded. The substantially zero offset sensor signal recording is performed for a sufficient time to detect seismic energy reflected from the subsurface.
