Ecopetrol’s Transandino pipeline was shut down Wednesday after a bomb attack by leftist guerrillas damaged the pipeline and caused an oil spill.
Exports and production at fields that use the 190 mile pipeline were not immediately impacted by the blast, Reuters said.
Colombia’s Ecopetrol has not disclosed when the pipeline is expected to be operational again or details about the size of the spill.
The Transandino can move up to 85,000 barrels of oil per day from fields in Colombia’s Putumayo province to the port city of Tumaco.
Army and police officials believe leftist rebel group the Revolutionary Armed Forces of Colombia (FARC) is responsible for the attack.
FARC called for an unlimited ceasefire from Wednesday to Saturday as it hosts a new round of peace talks with Colombian officials in Cuba.
Colombian rebel groups launched 136 attacks against pipelines from January to November of this year, down from 253 attacks during the same period last year, Colombia’s defense ministry said.
Colombia produces about 1 million barrels of oil per day and is the fourth largest oil producer in Latin America.
