Palagua-Caipal Field, Colombia
The Palagua-Caipal field is located in the middle Magdalena Valley, in the Honsa-La-Dorada sub-basin in the state of Boyaca. Texaco discovered the Palagua field in November 1954 and developed the field for 30 years. In 1986 the concession reverted to Ecopetrol, which operated the field until the consortium of JTI and partners (Two Colombian companies, Ismocol and Parko Services) entered into production contract with Ecopetrol in September, 2000. The estimated Original Oil in Place (OOIP) for the Palagua-Caipal field is about 1 Billion barrels of oil. As of March 31, 2012 approximately 117 million barrels of oil have been produced since the beginning of the production from the field.
Structure and Stratigraphy
The structure of the field consists of a large monocline deepening to the southeast, intercepted by the Velazquez-Palagua main strike fault, which is a wrench type fault running NE-SE. Next to this fault are satellite faults running SW-NE that generates eight separated blocks in the eastern part of the field. Exploration in this basin has been directed at prospecting for structural traps, mainly associated with major asymmetric anticlines, closure against faults and folds in over-thrust areas with Tertiary objectives. Occasionally, fractured limestone and stratigraphic traps associated with the wedging of the section on basement have been noted.
