Marismas project - Naturgy


Marismas project

The Marismas project is a continuation of the 30 years of activity that we have been carrying out in the Guadalquivir Valley area. It consists of removing the existing additional gas reserves and once the gas has been depleted, the site is used again as a storage area - the function it has had for millions of years. 

Sites like the Marismas Occidental are the safest storage areas in existence, as they have contained hydrocarbon for millions of years.
