Abstract
The Middle Magdalena Valley is an intermontane basin (Cooper, et al., 1995; Taboada, et al., 2000; Sarmiento-Rojas, et al., 2006) characterized by double vergence structures and flanked by the Central and Eastern Cordilleras (Córdoba, et al., 2000). The Campo Escuela Colorado oil field of the Universidad Industrial de Santander is located in the South Eastern zone of the Valley, associated with the western deformation front of the Eastern Cordillera. Previous works on this oil field have diverged as regards the structural model and the relationship with major structures (e.g., La Salina Fault). We present the results of 15 critical wedge simulation models to define the main structural characteristics in a compressive tectonic setting. Our results showed a deformation front dominated by thrust faults that verge towards the foreland and by associated backthrusts. The topographic elevation is caused by material stacked in the axial zone of the wedge. Based on the 15 experimental models we concluded that the geometry of the structure is dominated by thin flaking and that the structural model of the Campo Escuela Colorado is a triangular zone dominated by a backthrust. © 2018.
