BOGOTA, April 7 (Reuters) - Colombia's state-run Ecopetrol SA has declared force majeure on a small number of deliveries of medium Vasconia crude after the Cano Limon-Covenas pipeline was damaged by a series of attacks by leftist guerillas, a press official said on Monday.
The official could not specify on what date force majeure was declared, what quantities were involved or which clients would be affected, but said volumes were not significant enough to require notifying the country's stock market regulator.
The pipeline has been shut since a blast on March 25 in Toledo province, he said. Normally speedy repairs could not take place this time because of objections and demands made by an indigenous community near the site of the blast.
Government and justice officials have intervened to seek a solution to the demands, which include diverting the pipeline away from their area, the Ecopetrol press official said. A separate bomb attack took place elsewhere in the same province on April 1, he said.
Until repairs can begin, there is no estimate for when the 780 km (485 mile) pipeline, owned by Ecopetrol subsidiary Cenit, could reopen. It has capacity to transport 220,000 barrels per day. Continuación...
