A non-producing Talos Energy well in the Gulf of Mexico suffered a blowout on Tuesday, resulting in leakage of natural gas and condensate that has caused a sheen on the sea’s surface.

Talos Energy said that staff were evacuated and currently efforts are underway to permanently shut the well.

The natural gas and condensate began flowing on Monday and the well should be plugged within 24 hours.

It is thought the spill may have been caused by aged tubing on the well.

Based on the four-mile-wide by three-quarter-mile-long sheen reported by the Bureau of Safety and Environmental Enforcement (BSEE) and the US Coast Guard, it is estimated that approximately six barrels of light condensate have been leaked into the sea.

The incident brought back memories of the Deepwater Horizon oil spill disaster of 2010 that leaked 4.9 million barrels of crude oil into the sea.

"Talos Energy said that staff were evacuated and currently efforts are underway to permanently shut the well."

Talos Energy is currently working with the BSEE and the US Coast Guard to reduce the damage and environmental effects of the incident.

Talos Energy president and CEO, Timothy Duncan, was quoted by Reuters as saying: "In an abundance of caution, we decided to evacuate the platform and mobilise our spill response team, we notified the U.S. Bureau of Safety and Environmental Enforcement (BSEE) and the US Coast Guard, and we shut-in two other producing wells at the platform."

Located 74 miles southwest of Port Fourchon in the shallow Gulf of Mexico, the Ship Shoal 225 B-2 well produced mostly water in 1998 at a rate of 65,000ft³ of gas, 9 barrels of condensate and 1,150 barrels of water per day at a low flowing pressure of 175 pounds per square inch.

Talos Energy owns the well through its subsidiary Energy Resources Technology Gulf of Mexico.
