... operations would be ineffective. Laboratory tests demonstrated that dispersant would not be effective. However, tests revealed that the oil could be ignited and burned. Tests around the world indicated that in-situ burning could result in 95-98% of the spilled oil being eliminated. Cost savings of cleaning...
