OSRR-1029-Environmentally Benign Oil Simulants to Mimic the Behavior of Oil Droplets in the Ocean

This project developed a method to fabricate an environmentally benign, optically active particle that can simulate oil droplets in the water column. The synthesis technique of the oil simulant uses an innovative process to allow for tuning of the molecule size.  This flexibility in defining the simulant oil droplet size allows for better understanding of oil behaviors ranging from floating to sinking in the water column.

OSRR-1038-Biodegradation Following Dispersant Usage in a Cold, Stratified, Deep Sea Setting

PNNL will conduct a set of controlled laboratory experiments simulating environments of the US Outer Continental Shelf characterized by high pressure, low temperature, and low mixing to first characterize the performance of dispersants and second, to characterize subsequent biodegradation. Four sets of experiments are detailed that will characterize;

Development of acoustic methods to measure oil droplet size and slick thickness on ROV and AUV platforms

ARA (Applied Research Associates, Inc.) has developed and tested acoustic techniques and sensors mounted in free-swimming platforms [Remotely Operated Vehicle (ROV) /  Autonomous Underwater Vehicle (AUV)] for field applications to measure: (a) slick thickness on the surface of the water, and (b) oil droplet size distribution at the wellhead for subsurface releases of crude oil and dispersants in the presence of natural gas.

OSRR-668-Ohmsett Biofuels Feasibility Study

There has been increasing shift to use BioFuels (bio-diesels, and gasoline/ethanol blends) in the worldwide marketplace. The different physical and chemical properties of these products in comparison to the petroleum products they are replacing leads to the issue of response countermeasure actions in the event of a BioFuel spill.

OSRR-698-The Roles of Gas Hydrates During the Release and Transport of Well Fluids into Deep Ocean

The objective of this project is to use existing, novel equipment for obtaining fundamental, crosscutting chemical, physical, and hydrodynamic information on fluids that could be released and transported from deep, subsea hydrocarbon reservoirs and inadvertently released into a deepwater environment. Specifically, the research will use the resulting fundamental information in numerical, thermodynamic, and plume models to comprehensively describe potential roles and impacts of gas hydrates in such a scenario. The goal is to have a comprehensive understanding of:

OSRR-1017-Literature Synthesis of Oil Properties and Their Impact on Spill Response Options

The range of oil products transported through, explored for, and produced in U.S. waters has increased dramatically over the last two decades. With these increases, the potential for spills of new materials, in new locations, or in severe climates brings into question the efficacy of traditional cleanup and spill response options.

OSRR-585-Mitigating Oil Spills from Offshore Oil and Gas Activities by Enhancement of Oil-Mineral Aggregate Formation

This research project will assess the feasibility of a marine oil spill countermeasure strategy based on the stimulation of oil-mineral aggregate (OMA) formation. Experiments will be conducted on both laboratory and wave tank systems under controlled conditions to evaluate its potential effectiveness for the treatment of oil spills from ships, facilities or pipelines. Conceptual mathematical models will be developed from the data to identify the fundamental processes affecting operational effectiveness as a means to provide guidance for field operations.

OSRR-595-Identification of Window of Opportunity for Chemical Dispersants on Gulf of Mexico Crude Oils

The objective of this research was to develop best-fit correlations between readily available fresh oil properties and the window of opportunity for successful chemical dispersant use on Gulf of Mexico crude oils.

The goals of the work were to:
