Within the hydrocarbon exploratory activities, ANCAP requested an area to MIEM (Cañada de los Burros area) to study the possibility of coal deposits. The exploratory records regarding this resource were concentrated mainly in the beginning of XX Century in the East region of the Norte Basin. They indicate that the coal deposits can be found in the Tres Islas formation (Lower Permian).
Between 2013 and 2018, ANCAP had an area with an exploration permit to study this resource. Among the activities that were carried out in this area, the regional and detailed cartography with the highest concentration of antecedents and 13 stratigraphic wells are highlighted. They crossed centimetric coal levels as well as levels of carbonaceous shale interbedded between fluvio-deltaic sandstones of the Tres Islas formation.
