Website Map for Survey MCS Colombia Pacifico Legacy MC2D
Vintage but insightful seismic coverage of Manglares/Tumaco Basin, Colombia Pacific offshore.
Surface indications of oil and gas have been reported at numerous locations and a number of wells both onshore (12) and offshore (4) that have yielded gas shows, mainly from the Oligocene-Miocene section. The source rocks are of Cretaceous and Lower Tertiary age and are oil and gas prone.
Reprocessed from field data and interpreted.
