Chevron Rig Fire Nigeria

Workers on the KS Endeavor and on a support barge were evacuated and treated at a nearby platform, Chevron said in a statement.

The rig was drilling an exploration well for the supermajor on Oil Mining Lease 86 as part of a joint venture with Nigeria’s NNPC.

Chevron did not immediatly have a count of those injured or whether there were any fatalities.

“We are still investigating the incident and are working to fully understand what happened,” Chevron spokesman Scott Walker said. “Our primary focus continues to be the safety and security of our workforce, including employees and contractors.”

Production at the nearby North Apoi platform was shut in because of its proximity to the fire, Walker added. No spills were reported.

The jack-up was contracted by Fode Drilling, Chevron said.

A profile of the KS Endeavor on the website of Atlantic Oilfield Services shows that has been under contract to Chevron in Nigeria from January 2011 to January 2013.

The rig, which has a crew capacity of 130, was delivered in 2010.

It can drill to depths of 30,000 feet in up to 300 feet of water.
