| Sumario: | The objective of this work is to analyze the different stages that hydrocarbon exploration has had in the province of San Juan and thus understand what led the explorers of Yacimientos Petrolíferos Fiscales (YPF) to propose the Niquivil Viejo-1, the first well exploratory in the year 1947. The pioneering figures of Fossa Mancini, Tarragona, Bracaccini, among others, emerge which, based on effort and experience, were able to achieve this milestone. Over the course of almost eight decades, other Companies joined YPF, managing to drill a total of 21 wells. The majority aimed to investigate Triassic reservoirs, following the prospective model of the Cuyana Basin. Only the Pampa Vieja well x-1 investigated a trap formed by medium-lower Paleozoic deposits in the Central Precordillera. Geochemical analyzes carried out between generating levels and hydrocarbon manifestations confirm the existence of an oil system of Paleozoic age. The outcrops of bituminous rocks of Triassic age with a high percentage of total organic carbon do not have the thermal maturity necessary for generation and expulsion. Recent studies carried out by YPF have allowed us to propose the existence of a triangular zone of “thin skin” between the Central and Eastern Precordillera, which could constitute a new exploratory challenge for this frontier region. |
