The Ayoluengo oil field is an oil field located in Sargentes de la Lora, Province of Burgos. It was discovered in 1960 and developed by Leni Oil & Gas. It began production in 1961 and produces oil. The total proven reserves of the Ayoluengo oil field are around 104 million barrels (13.9×106tonnes), and production is centered on 225 barrels per day (35.8 m3/d).[2]

Geology

The 10 km2 field consists of a Triassic salt-cored anticline with 200 m of vertical closure. Oil and gas are produced from more than 50 lenticular sandstone bodies of Late Jurassic to Early Cretaceous age. These sandstone bodies lie at a depth of at least 1300 m. The last well was drilled in 1990, making for a total of 52. Only 10 wells were active by 2016, when the cumulative production had reached 17 million barrels of oil.[3]
