This is a shallow-water natural gas rig, so rather different in its effects from the U.S. Gulf coast disaster.

Al Jazeera, Sunday: "Fear over Nigeria oil rig fire, Locals in Niger Delta complain of health problems, but Chevron says two-week-old blaze is causing no harm."

Chevron is in trouble for a deep water oil spill in Brazil last fall... Reuters, Jan. 6, 20: Exclusive: Chevron to face charges over Brazil spill

On November 7, a well drilled by Chevron using a Transocean rig 107 kilometers (73 miles) from the coast of Rio de Janeiro state, experienced a pressure "kick" after tapping into an oil reservoir in Frade.

An emergency blow-out preventer was activated, plugging the well 1,200 meters (3,937 feet) below the ocean surface. But days later, Chevron discovered oil seeps from the seafloor hundreds of meters from the plugged well. Pressure caused a breach of the well wall far beneath the seabed, allowing oil to infiltrate surrounding rock and work its way into the ocean, Chevron said.
