According to ERT’s site assessment, natural gas is flowing from the well and there is a rainbow sheen visible on the surface estimated to be more than four miles wide by three quarters of a mile long.
The rainbow sheen is caused by oil, not gas.
The loss of control happened as workers tried to temporarily plug the well.
The platform has a history of many irregularities:
According to federal data, the platform where the blow-out took place has been cited for 12 incidents of non-compliance since 2008.
