Deepwater Oil-spill Modeling For Assessing
Environmental Impacts

Abstract
Oil and gas activities in deepwater (areas deeper than 340 meters) have
proceeded at an unprecedented rate, and have led to concerns about oil released
by accidents near the seafloor. Oil and natural gas releases in deep water behave
much differently than in shallow water. This is primarily because of the density
stratification, high pressures, and low temperatures found in deep water. Some
physical and chemical changes that occur in deepwater environments may
significantly reduce the buoyancy of the plume and keep large amounts of the oil
submerged for an extended time. This has significant implications for
environmental impact assessment, oil-spill cleanup, contingency planning, and
source tracing.
The Minerals Management Service (MMS) performs an oil-spill risk analysis
(OSRA) to estimate the
