| The example below shows images of a channel system at 600m depth obtained with inversion using seismic data recorded at the sea floor. The top row show the true P-wave (left) and S-wave (right) velocity models, whereas the bottom row shows the inverted P- and S-wave velocity models. | The example below shows images of a channel system at 600m depth obtained with inversion using seismic data recorded at the sea floor.

| Time-lapse seismic inversion is a rather new application of the method. The purpose of the application is to reveal changes in time in the subsurface due to for instance production or injection of CO2. The left figure below show the true time-lapse effect in the channel system, whereas the right figure show the time-lapse effect obtained using inversion. | Time-lapse seismic inversion is a rather new application of the method.
