Patterns and origins of the porosity in the productive reservoirs of the upper part of the Chubut Group, southern flank of the Golfo de San Jorge Basin, Patagonia Argentina

Journal of South American Earth Sciences, 2020
Abstract The Mina del Carmen, Bajo Barreal and Canadon Seco Formations bear the most important Cretaceous reservoirs in the southern flank of the Golfo de San Jorge Basin, in which the porosity is mainly secondary in origin. Primary porosity is about 4% in average and can be divided in intergranular and intercrystalline porosity, the former is better

Sandstone petrography and provenance of the Chubut Group (Cretaceous) in the Matasiete Canyon (Golfo San Jorge Basin, central Patagonia): implication for basin evolution and alluvial organization

2020
Sandstone petrographic data have been used to investigate the provenance of the Matasiete, Pozo D-129, and Castillo formations (Chubut Group) in the Cañadón Matasiete, San Bernardo Fold Belt at Golfo San Jorge Basin, Argentina. Available petrographical data provides evidence of several distinctive volcanic source areas, with minor contributions of ...
