Other comments The Ayoluengo oil field is the only onshore oil discovery in Spain. To date, 17 million barrels of oil have been produced from Purbeck sandstones generated from a Lower Liassic source rock. It is located over a Late Jurassic salt anticline with approximately NE-SW axial orientation, close to the Polientes evaporite structure..
