Brazil's state-controlled oil company says it detected and later contained a small gas leak on one of its oil platforms off the coast of Rio de Janeiro.
Petroleo Brasileiro SA says in a statement that a minimum amount of gas leaked from its P-40 platform Friday morning and was contained later in the day. It says there is no risk of fire or explosion.
Less than three weeks ago, oil started leaking at the site of an appraisal well operated by Chevron off the coast of Rio de Janeiro.
On Wednesday, the National Petroleum Agency banned the California-based company from drilling for oil until the causes of the ongoing leak are identified. The agency has said that more than 110,000 gallons (416,400 liters) of oil have leaked into the Atlantic ocean.
