Determination of the sound speed of the water column using seismic survey data.

Project Description: This project aims to carry out the processing of seismic data already acquired in the section referring to the water column, integrating oceanography and seismic reflection, to obtain oceanographic parameters. Objective processing details the behavior of sound speed and temperature in the water column, as well as remotely identifying water bodies and the presence of internal waves, as a subsidy for increasing the quality of subsurface imaging during seismic surveys. The estimation of these parameters by acoustic methods brings two major advantages over conventional measurement methods: (1) the possibility of estimating the parameters using the reflection seismic data themselves, which makes it unnecessary to stop vessels during withdrawals for CTD or XBT measurements and (2) much larger sampling of the environment, allowing the use of much more detailed models in the correction of overtime and migration of seismic measurement data. The creation of new, more detailed models of sound speed in the water column, brings a significant improvement in seismic data processing, increasing the quality of the seismograms obtained and, consequently, facilitating the location and monitoring of oil and gas wells and other subsurfaces structures.
