Historical hydrocarbon manifestations

Geo-referenced vector database containing with a punctual symbolism the manifestations of hydrocarbons collected in the first decades of the last century by Agip geologists, both directly and through appropriate bibliographical reports. The total number of events is 1004; many of these (809) are illustrated in an internal technical report of Eni SpA, (Mosca L.; 1983: Hydrocarbon manifestations in the Emilia-Romagna Region. ENI S.p.A., S. Donato Milanese, Italy, Internal Technical Report, vol. 2, 691 pp.), the remaining 195 (70 of which immediately outside the regional borders) are documented only through their location and typology, shown in the maps contained in the above-mentioned report. SGSS geologists analysed and synthesised in a geographical database the information contained in the cards and maps; the online publication of this database has been agreed with ENI. The events were grouped into twelve categories (field name: type_synthesis): running water with gas (30), salt water and hydrocarbons (9 + 41 = 50), gas (55 + 154 = 209), well gas to water (145), drilling gas (79 + 139 = 218), gas and oil (9 + 89 = 98), gas and drilling oil (1 + 29 = 30), surface gas (29), oil (37 + 91= 128), drilling oil (3 + 7 = 10), exploratory wells (30), sauce and hydrocarbons (2 + 25 = 27). The numbers in italics indicate the points for which there is a sheet, additional information may be available compared to the type of the event. This information can be: a more accurate description of the type of the event (field name: Tipo_total), the depth of the wells (field name: Prof), the date of detection or notification of the event (field name: Data_min), whether or not the signal is derived from drilling a hydrocarbon well (field name: pz_idroc), the detail of the topographic reference (field name: Altri_rife), the original name of the well (field name: Num_well), annotation of various kinds (field name: Note_1), the depth range at which the event was found (field name: interval).
