Floatseis: Aims to obtain precise and reliable velocity model regardless of complexity of geological environment is the task which can be failed by CDP reflection towed streamer surveys only. Therefore, an alternative source of information on velocities should be used such as long-offset refracted wave data.
The objective depth of exploration surveys usually limited by depth accessible for wells drilling and doesn’t exceed 5-7 km. Thus, refracted wave recorded offsets range up to 35-40 km will be enough to achieve desirable survey depth. To record this offset range simultaneously with towed streamer CDP reflected wave survey, a FloatSeis™ field party and an additional support vessel with an opportunity to mount onboard 20’ standard dry container are required.
