Norway’s Statoil is investigating a nearly 400 gallon chemical spill at its subsea Gullfaks project in the Norwegian North Sea.

According to Energy Voice, Statoil has assembled a team of technical experts to pinpoint where a 396 gallon, or about 1,500 liter, spill that released barrier fluid into the water began.

Barrier fluid is used to lubricate and cool compressors.

The fluid is categorized as persistent or very acutely toxic by the Norwegian Environmental Agency, Energy Voice added.

No injuries have been reported.

Further details about the leak have not been disclosed yet.

Norway-based Statoil started up operations at the field’s west gas compression project in October.

The subsea wet gas compression technology is expected to boost recovery by 22 million barrels of oil equivalent and extend plateau production from the Gullfaks South Brent reservoir by about two years.

The project is the first in the world to utilize subsea wet gas compression technology.

The main Gullfaks field lies in block 34/10 in the northern part of the Norwegian North Sea.

Statoil operates and holds a 51 percent stake in the Gullfaks license. Norway’s Petoro holds a 30 percent stake and Austria-based OMV holds a 19 percent stake.
