On October 12, Niger's Ministry of Petroleum announced that the W8 well at Goumeri has still not been fully controlled since the blowout on September 25, constituting an "extremely serious environmental accident," and that an independent investigation backed by Algerian experts has already been launched.
On September 25, a blowout occurred at the Gumere W8 well in Niger, operated by a subsidiary of CNPC. Crude oil and natural gas sprayed more than 10 meters into the air, the integrity of two other wells on the same platform was affected, and two employees were injured and hospitalized.
