The seismic shoot, which was finished earlier this year, was carried out by WesternGeco on blocks CAA-40 and CAA-46, where Repsol is partnered by Pan American Energy, an Argentine-based company controlled by BP.
The blocks are located in water depths ranging from 500 metres to 600 metres.
Pan American moved into the two blocks when both BG Group and France's Total disposed of their interests in the area three years ago.
