Abstract
Summary
We present a next generation seismic source. The Tuned Pulse Source is a new pneumatic seismic source designed to operate with low-pressure air. It releases a large volume of air into the water over a controlled time generating a pulse with a long rise time and a bubble with a long period. The long bubble period produces strong low frequency signal for velocity model building with methods such as Full Waveform Inversion, for imaging subsalt and sub-basalt, and for building blocky reservoir models using Inversion. Compared to airguns, the TPS has a stronger low frequency content and a lower environmental impact.
