Geochemical Characterization of Irati And Palermo Formations (Paraná Basin–Southern Brazil) for Shale Oil/Gas Exploration

Abstract: Shale gas/oil currently are two of the most important unconventional energy resources. Their exploitation has caused an energy revolution in USA, and many countries are investing in it. Brazil has large areas covered with sedimentary basins, but little attention has been devoted to the study of shale containing oil and gas. The parameters analyzed and studied for geochemical data evaluation are: clay mineral identification, mineral matter analysis, elemental analysis (including total organic carbon, total carb… Show more

“…The focus was on the kerogen and mineral matter components that may affect pyrolysis and the kinetic investigation. X-ray diffraction data is also presented, but characterization did not include a full mineralogical characterization, which was reported in the literature recently …”

“…Esta pirólise em duas etapas é comumente observada em estudos em que a faixa de temperatura em estudo se estende para além de 527 °C. Existem vários minerais do tipo argila presentes no xisto Irati, conforme cita Ramos et al, (2015), e estes tipos de materiais de sílica-alumina tem alguma acidez de Brønsted-Lowry que poderia facilitar a decomposição em altas temperaturas.…”

“…Outras alterações que parecem estar relacionadas principalmente à matéria mineral é a absorção a 1110 cm -1 devida ao grupo sulfato (SO 4 2-), que se torna cada vez mais proeminente à medida que mais querogênio é removido do xisto pelo processo de pirólise. Provavelmente é devido à presença de gesso no folhelho de Irati (RAMOS et al, 2015). O aumento na absorção de 617 cm -1 e o aparecimento de absorção a 563 cm -1 é atribuído à absorção por vários óxidos metálicos (COLTHUP et al, 1990).…”
