More than 2,500 barrels of oil spilled at the Frade field operated by Chevron off the coast of Brazil in November. The company reported a similar incident near the same area last month.
Brazil charged executives from Chevron and rig-owner Transocean with environmental crimes tied to the oil leak in November. The government said the companies weren't acting responsibly during their operations at the Frade field.
Brazilian Prosecutor Gisele Porto said, in a new filing obtained by Bloomberg News, that each company should be suspended until they're able to stop damage from the November spill and face fines of $273 million for each day they don't comply.
Chevron, in a full-page advertisement published in Brazilian newspapers, said the charges against it were unfounded.
"Protecting the environment is a core Chevron value and it has been one of our primary concerns," the company said in a March statement. "Continuous monitoring of the incident area shows no environmental impact to marine life."
