... for this and similar igneous rock plays is the main motivation of our study. We explore the evolution of this play type by an analysis of the Los Cavaos oil field, located in the Malargue fold belt of the Neuquén Basin, Argentina, integrating multiscale fracture data from outcrops and subsurface. The field was created...
