Exploration based on a seismic image focuses on obtaining three-dimensional images of the outer layers of the Earth's crust. To explain this, Ortigosa makes a further comparison: "We perform large scans of the inside of the Earth". To do so, vessels drag sensors called hydrophones that pick up sound waves generated by large compressed air canons. These waves are reflected and refracted as they pass through the different layers of the substructure and the time required for their journey is recorded. This data undergoes computerised processing that uses complex mathematical algorithms to reconstruct the geological profile of this layer of the Earth's crust.
However, while in medicine scans can be performed in real time, a seismic campaign can require between 10-20 Terabytes of data and to process this data a supercomputer like the one Repsol built in its Houston centre (US) that has a calculating capacity of 128 Teraflops (128 billion operations per second) that is equivalent to 10,000 PCs.
The mathematical equations that have the capacity to process this information required supercomputers with such high calculation capacities that it was thought impossible
We would need equipment that is a million times more powerful than current equipment to achieve higher quality virtual models
