Computer chips for exploring underground

With the Kaleidoscope Project, we can locate reservoirs 15 times faster than the industry average. We do this with computer chips that enable us to see the subsoil without drilling into it.

Thanks to the KALEIDOSCOPE PROJECT, the techniques for finding deposits are now faster and more accurate. The Kaleidoscope project was launched in 2007 as a combination of science and cutting-edge technology. And with it, at Repsol we are discovering new reservoirs of oil and gas while respecting the surrounding environment.

We have created a technology to process information 15 times faster than other companies in the industry. This is possible thanks to a new generation of computer chips capable of handling complex mathematical algorithms. These chips create seismic images with which the Earth’s interior can be ‘seen’ and analyze whether there are hydrocarbons without drilling into its crust. It increases the reliability of the seismic images, boosting the chances of finding oil and gas thousands of meters beneath the subsoil. This technology has placed our Company at the forefront of the exploration of complex zones and large reserves, such as the Gulf of Mexico and Brazil. It has been estimated that the equivalent of 100 million barrels of oil is hidden there.

To make this tangible, Repsol has employed the services of some of the best geophysicists, mathematicians, geologists and engineers in Spain and the United States. The Kaleidoscope project was designed by Repsol in conjunction with 3D-GEO, a leading company in obtaining seismic images, and the Barcelona Supercomputing Center, which has the MareNostrum, one of the most powerful supercomputers in Europe. Repsol has also worked on this advanced program with IBM, the Higher Center for Scientific Research, the Polytechnic University of Catalonia, and Stanford University.


Kaleidoscope has been considered one of the five most innovative projects in the world by the U.S.-based Institute of Electrical and Electronics Engineers, a recognized organization in the monitoring of new technology. The magazine Computer World awarded Repsol for this project. We were also named as finalists at the Annual Creativity in Electronics Awards and for the Innovation Award given by the magazine Petroleum Economist.
