“Dighe di pece e di asfalto”: Bitumen exploitation history in the Abruzzo region (Central Italy) across the 20th century

In this article we present the history of the exploration and exploitation of solid hydrocarbons in what has been known for a long time as the Bacino Minerario Abruzzese (Abruzzo petroleum district), in Central Italy, in the first part of the 20th century.From the antiquity, bitumen and asphalt were locally collected from surface seeps. Industrial scale extraction started in the second half of the 19th century, with Italian and foreign companies. AfterWorld War I, the Italian government repossessed the bitumen exploitation concessions hold by foreigners and re-assigned them to Italian entities. Afterwards, during the Fascist period, the government stepped up the pace of industrial development under the autarky (self-sufficiency) policy.From a technical standpoint, positive results were achieved thanks to the continuous support of geological evaluation studies. Also today these areas represent an important calibration and analogue forgeoscientists to evaluate hydrocarbon residual potential in the whole region.The title of this article was inspired by the words used by geologist Giovanni Capellini (1833-1922) in his historical evaluation work of the bitumen deposits of the Maiella Mountain north-westflank (Capellini, 1866).
