Nigerian militant group says it blew up two Chevron wells---Reuters

A Nigerian militant group said on Wednesday that it had blown up two Chevron oil wells in the second such attack in a week on the company's facilities in Nigeria's oil-producing Delta region.

The attacks occurred as tensions flared between international oil companies and Niger Delta residents, some of whom are pushing all foreign energy companies to leave Africa's largest economy in a bid for greater economic self-reliance.

A group calling itself the Niger Delta Avengers (NDA) said in a post on Twitter that it used "100 Gunboats, 4 Warships and Jet Bombers" to attack Chevron's RMP 23 and 24 wells early on Wednesday morning. It claimed the wells were Chevron's highest-producing in the country.

The attacks have reduced Nigeria's total oil output to below that of rival producer Angola, sharply affecting the national budget which relies on oil tax revenue.

The Niger Delta Avengers had told Chevron and other oil companies to leave Nigeria by the end of May. Last week the group claimed responsibility for blowing up electricity feeds to Chevron's facilities, forcing the company to shutter onshore operations.

The wells are in the Dibi field near Warri, about 265 miles (426 kilometers) southeast of Lagos, Nigeria's largest city.

Local residents confirmed to Reuters that an attack had taken place.

In response to a request for comment, Chevron spokesman Kurt Glaubitz said, "As a matter of long-standing policy, we do not comment on the safety and security of our personnel and operations."

It was not clear what effect the attacks would have on Chevron's daily Nigerian output. Last year Chevron pumped about 224,000 barrels of oil per day in Nigeria, about 9 percent of the company's total global output. Chevron also produces natural gas in the country.
