Colombia's Trasandino pipeline was damaged in a bomb attack, state-run oil company Ecopetrol said on Oct. 5, spilling crude into a nearby river.
The attack took place in Orito municipality in Putumayo province, the company said in a statement.
The pipeline was not functioning at the time of the attack, which affected the Guamues River, Ecopetrol said.
It is the nineteenth attack this year on the Trasandino.
Although Ecopetrol did not name the group responsible for the attack, the leftist National Liberation Army (ELN) rebels, considered a terrorist organization by the United States and the European Union, regularly bomb oil infrastructure.
To maintain production, operators must drill new wells or optimize production on their existing ones.
Large-scale, multiwell pad projects show hits and misses.
Demand for workover rigs in the Permian Basin has remained low with the majority of work focused on maintaining producing wells to keep cash flowing.
