While wellhead burning has been an oil field hazard for generations, the oil exploration community has begun to view it as a potential spill response tool. Presently, there are significant gaps in the validated science to reliably and accurately predict the burn efficiency of a wellhead. A coupled, multi-physics spray combustion model has been developed and validated with multi-scale experiments for wellhead burning. Spray measurement and sub-scale burn efficiency measurement methods have been developed and applied to determine the behaviors that drive low wellhead burn efficiency. Analysis of potential wellhead spray conditions revealed that the worst-case discharge scenario may not create the worst-case spill scenario because lower flow rates produce thicker wellbore films, which lead to lower burn efficiencies.
