The Yaguará field is located in the Hobo Block, in the Upper Magdalena basin. The field was discovered by Intercol in 1987 and brought onstream by Exxon in 1992. Production peaked at just under 9,000 b/d in 1993 and has generally been in decline since then. The Yaguará oil field is located at the southern end of the Upper Magdalena basin. The Cretaceous Caballos sands act as the reservoir in the field and the Cretaceous-age Villeta shale is the primary hydrocarbon source rock.
