This study will measure the influence of oil characteristics and temperature on herder efficacy at the lab scale. ARA will systematically test the function of chemical herders across several crude oils. Both commercially available herders and emerging new formulations will be utilized. The herders will be tested on crude oils with varying properties. This information will support operational decisions to use herders during a response, and enhance the Bureau of Safety and Environmental Enforcement's ability to evaluate the feasibility and likelihood of successful use of chemical herders.
The contract was awarded to Applied Research Associates on August 29, 2016. The project's kick-off meeting is expected to take place in early October 2016.
