The document discusses seismic reflection acquisition, processing, and waveform analysis. It describes how seismic reflection uses sound waves reflected off subsurface rock layers to image the detailed structure and stratigraphy below the Earth's surface. Reflection seismology has been used since the 1920s as a key tool in oil and gas exploration both on land and at sea, imaging features from tens of meters to crustal and mantle-scale depths. The document outlines the basic components and objectives of seismic reflection surveys.

Editor's Notes
- qqq
- Normal Incidence: Reflections from the common source/receiver positions result from ray paths striking reflectors at 90.
- An unmigrated time section , presents each seismic trace as if a source and a receiver were in the same position.
