French oil firm Total SA says natural gas leak ongoing at a plant in Nigeria's Niger Delta

LAGOS, Nigeria – French oil firm Total SA says a natural gas leak at its plant in Nigeria’s oil-rich southern delta may have been going on for weeks.

In a statement, Total says its Nigerian subsidiary discovered the leak April 3 at its Obite gas site. Total says it has evacuated the surrounding area.

The company said the leak may have been caused by a “technical incident” that happened at the site March 20. Total spokesman Charles Ebereonwu said he did not have details of the March 20 incident.

The company has not made a publicized statement about the leak since it began. Ebereonwu said Total had been updating its Nigerian subsidiary’s website with details.
