CASTOR UNDERGROUND NATURAL GAS STORAGE (UGS) PROJECT

The Castor UGS project is an estimated $2 billion investment in supporting Spain's natural gas infrastructure. With a withdrawal rate of 25 million cubic metres per day, Castor will provide approximately one-third of Spain's UGS deliverability requirements and virtually 100% of the east coast's UGS capacity. The high daily withdrawal rate is equivalent to the capacity of a large LNG regasification plant - an important competitive advantage.

The UGS project will utilize the depleted Amposta oil reservoir. Its structure is 5 kilometres long, 2.5 kilometres wide and up to 250 metres thick, providing an estimated total of 1.9 billion cubic metres of storage capacity. The underground reservoir's size and porosity provide storage volume equivalent to 14 LNG transportation tankers.
