Farmers of Anaimangalam village near Kilvelur were shocked to find crude oil layer over their fields this morning and their crops damaged due to the oil spill.
The ONGC Cauvery Project headquartered at Karaikal has its production installation at the village and pipelines, which run through Anaimangalam, Karumangudi and Pakkur villages, had been laid for transporting crude oil to the CPCL refinery at a nearby village.
Alleging that the pipelines had developed cracks leading to the spill, three of the affected farmers lodged a complaint with police stating that crude oil had seeped into ten acres of their paddy fields.
ONGC authorities, however, pointed out that there were no breaches or cracks in any of the pipelines being used in production at present.
Analysis by ONGC Engineers has revealed that the crude oil seeped from an old pipeline, running deep down near the paddy fields, which was abandoned during September after detection of oil leak. They had replaced it with a new one, ONGC sources said.
"Preliminary investigation suggests that the oil deposit due to that seepage have surfaced now, probably due to the recent heavy rains," an ONGC official said.

Kilvelur area recorded the highest rainfall in the district early this week due to cyclone Nilam.
"Our engineers are analysing the situation and will take steps to remove the oil layer from paddy fields. Steps have also been taken to find a permanent solution and ensure that farmers do not face any further issues," the official said.
The extent of damage, exact number of acres affected are being assessed, the official said, adding that suitable compensation would be offered.
President of Farmers Protection Forum Dhanapalan said the oil spill would turn the farmland unusable for at least three years. He demanded that ONGC thoroughly check its pipelines and ensure that such incidents do not recur.
