Detección de potenciales zonas con hidrocarburos en el Bolsón de Tamberías mediante técnicas geofísicas no convencionales

Abstract

En el presente estudio aplicamos una técnica antigua y poco utilizada en nuestro país, como es la técnica de normalización del Torio aplicada a datos aéreos de espectrometría de rayos gamma, como guía para el reconocimiento de acumulaciones de petróleo en el subsuelo. Esta técnica utiliza mediciones espectrales de rayos gamma en la prospección de petróleo en trampas estratigráficas y estructurales. Complementamos esta técnica con datos aeromagnéticos para analizar los principales alineamientos de estructuras geológicas en la corteza superior. El área del Bolsón de Tamberías fue escogida para aplicar esta técnica debido a los antecedentes de los depósitos triásicos del Grupo Rincón Blanco, donde el potencial oleogenético está bien documentado en la Formación Carri zalito. Además, al oeste sobre el actual frente de deformación de la Precordillera Occidental, afloran las secuencias triásicas de los grupos Barreal y Sorocayense, donde se han identificado interesantes niveles lacustres con potencial oleogenético. Los resultados encontrados con esta técnica son muy alentadores ya que las zonas donde se dan los valores máximos de DRAD (Deviation of Ra dio-Active Derivative) coinciden con las manifestaciones del grupo Rincón Blanco y con el muestreo de rocas realizado en esta zona.

In the present study, we apply an old technique that is not widely used in our country, such as the Thorium normalization technique applied to aerial data from gamma-ray spectrometry, as a guide for the recognition of oil accumulations in the subsoil. This technique uses gamma-ray spectral measurements in prospecting for oil in stratigraphic and structural traps. We complement this technique with aeromagnetic data to analyze the main alignments of geological structures in the upper crust. The Bolsón de Tamberías area was chosen to apply this technique due to the background of the Triassic deposits of the Rincón Blanco Group, where the oleogenetic potential is well documented in the Formation Carrizalito. In addition, to the west of the current deformation front in the Western Precordillera, the triassic sequences of the Barreal and Sorocayense Groups outcrop, where interesting lake levels with oleogenetic potential have been identified. The results found with this technique are very encouraging, since the areas where the maximum DRAD (Deviation of Radio-Active Derivative) values occur coincide with the manifestations of the Rincón Blanco group and with the rock sampling carried out in this area.
