Statoil evacuated all but a brave core of rescuers and technical staffs from the Snorre A platform Sunday night, after a larger-than-thought gas leak during a well workover.
Statoil reported Monday that crews were "pumping heavy drilling mud" into the leaking injection well in an effort to build "barriers".
“The mud is intended to push back the gas so that we can get at the well to halt the leak,” Statoil vice-president for the Tampen area, Øivind Reinertsen, was quoted saying.
Personnel flying to the platform Monday will relieve an emergency response team that worked through the night, some of the 36 left behind to combat the leak when 180 were evacuated.
Snorre is the eigth biggest field in the Norwegian sector, with its reserves of 254 million standard cubic metres of oil euivalent.
The field is just east of the aging Statfjord field, in about 350 metres of water.Snorr uses gas, water and foam to maintain wellhead pressure. No injuries were reported.
