| description | The Cauca-Patía Basin (CPB) is an intermountain depression which separates Colombia’s Central and Western mountain chain. The Alto de Popayán borders the Cauca Subbasin, to the north, and from the Patía Subbasin, to the south. The former is mainly covered by quaternary alluvial deposits. In the southwest margin there is an outcrop of sedimentary rocks from the Palaeogene. On the contrary, inthe the Patía Subbasin mainly appear folded and faulted rocks from the Palaeogene and the Neogene. Margins are formed by regional reverse and strike slip faults. Towards the inner part of the CPB, inverse faults of the Late Miocene with westward vergence are generally found. The CPB was formed by the collision and accretion of oceanic terrains on the west margin of the South American Plate during the Mesozoic and Cenozoic periods. Chimborazo, Ferreira, Mosquera and Cinta de Piedra Formations, as well as some levels of the Guachinte Formation (Late Palaeocene to the Mid Miocene) are grain-coarse clastic units (sandstones and conglomerates) which can be potential reservoir rocks. Aguaclara, Peñamorada and Chimborazo Formations (Upper Cretaceous and Lower Eocene) have levels of good characteristics to generate hydrocarbons. (%TOC > 1 and Hydrogen index values > 300 mgHC/gTOC) and type II kerogen. To the south of the basin there are two oil seeps in the Matacea creek, Mercaderes town. Volcaniclastic deposits from Galeón and La Paila Formations, and locally, levels of intra- formational clays which are present in all reservoirs may be regional seal. Traps associated to folds due to fault propagation folding are observed in the Patía Subbasin. In the case of the Cauca Subbasin, the structural style is associated to block tectonics which affects the basement. The types of traps are related to stratigraphic pinch outs and cut-offs against reactivated normal and inverse faults. There is an additional exploratory opportunity in the Cauca Subbasin related to the presence of carbons in the Guachinte formation; and the possibility of methane gas associated to the foresaid carbons. |

La Cuenca Cauca-Patía es una depresión intermontana entre las cordilleras Central y Occidental, en Colombia. El Alto de Popayán limita las Subcuencas Cauca, al norte, y Patía, al sur. La primera está cubierta por depósitos cuaternarios aluviales, al suroeste, aflora una franja de rocas sedimentarias paleógenas. En la Subcuenca Patía afloran rocas Paleógenas y Neógenas plegadas y falladas. Está limitada por fallas regionales inversas y de rumbo. Al interior, muestra fallas inversas del Mioceno Tardío con vergencia occidental. Esta cuenca fue formada por colisión y acreción de terrenos oceánicos al margen occidental de la Placa Sudamericana, durante el Mesozoico y Cenozoico. Las Formaciones Chimborazo, Ferreira, Mosquera, Cinta de Piedra y algunos niveles de la Formación Guachinte (Paleoceno Tardío-Mioceno Medio) son unidades clásticas de grano grueso, que pueden ser potenciales rocas almacenadoras. Las Formaciones Aguaclara, Peñamorada y Chimborazo (Cretácico Superior-Eoceno Inferior) poseen buenas características para generar hidrocarburos (%TOC&gt,1, índice de Hidrógeno&gt,300 mgHC/gTOC) y kerógeno tipo II. Al sur de la cuenca hay dos rezumaderos de aceite en la quebrada Matacea, municipio de Mercaderes. Depósitos volcanoclásticos de las formaciones Galeón y La Paila y, localmente, niveles de arcillas en los reservorios, podrían ser sello regional. La Subcuenca Patía presenta trampas asociadas a pliegues por propagación de falla. La Subcuenca Cauca tiene tectónica de bloques, que afecta al basamento, las trampas consisten en pinchamientos de unidades contra el basamento, y truncamientos por fallas normales o inversas reactivadas. Para la Subcuenca Cauca, el gas metano asociado con los carbones de la Formación Guachinte constituye otra oportunidad exploratoria.
