Criação de zonas de alta permeabilidade em fraturas: modelagem numérica do Lajedo de Soledade, Formação Jandaíra, Bacia Potiguar

The fracturing in carbonate rocks has been attracting increasingly attention due to new oil discoveries in carbonate reservoirs. This study investigates how the fractures (faults and joints) behave when subjected to different stress fields and how their behavior may be associated with the generation of karst and consequently to increased secondary porosity in these rocks. In this study I used satellite imagery and unmanned aerial vehicle UAV images and field data to identify and map faults and joints in a carbonate outcrop, which I consider a good analogue of carbonate reservoir. The outcrop comprises rocks of the Jandaíra Formation, Potiguar Basin. Field data were modeled using the TECTOS software, which uses finite element analysis for 2D fracture modeling. I identified three sets of fractures were identified: NS, EW and NW-SE. They correspond to faults that reactivate joint sets. The Ratio of Failure by Stress (RFS) represents stress concentration and how close the rock is to failure and reach the Mohr-Coulomb envelopment. The results indicate that the tectonic stresses are concentrated in preferred structural zones, which are ideal places for carbonate dissolution. Dissolution was observed along sedimentary bedding and fractures throughout the outcrop. However, I observed that the highest values of RFS occur in fracture intersections and terminations. These are site of karst concentration. I finally suggest that there is a relationship between stress concentration and location of karst dissolution in carbonate rocks.

Oscuridad y zonas grises en El lápiz del carpintero y La lengua de las mariposas de Manuel Rivas : Con una coda argentina: La pregunta de sus ojos de Eduardo Sacheri

En La lengua de las mariposas y El lápiz del carpintero Manuel Rivas presenta conflictos y personajes inmersos en el contexto de violencia y opresión desatados por el accionar de las fuerzas franquistas triunfantes en Galicia. Por su parte, uno de los hilos narrativos desarrollados por Eduardo Sacheri en La pregunta de sus ojos, se interna en la relación entre el delito, la impunidad y el castigo en el marco de la violencia estatal que se instala en Argentina en los años anteriores al golpe militar de 1976. En los tres relatos los comportamientos indignos o criminales, cuya génesis es inseparable del terror impuesto por una dictadura u otras formas de violencia emanadas de un poder opresor, disparan interrogantes de complejas respuestas. El concepto de zona gris que acuñó Primo Levi en su obra dedicada a testimoniar su experiencia de deportado en Auschwitz ofrece una vía de reflexión para volver más inteligible la respuesta del ser humano en situaciones límite.
