研究了在冰覆盖的水中轻质原油的平均浮油厚度、表面分布和燃烧效率，以确定化学牧油器在促进石油就地燃烧方面的有效性。实验在小规模（1.0 m2）和中型（19 m2）装置中进行，开放水域和 3/10、5/10 和 7/10 碎冰覆盖。每个实验中聚集的浮油厚度（3-8 毫米）都是可点燃的。冰的存在导致油在聚集过程中破裂，从而减小了聚集的浮油的尺寸，从而降低了它们的可燃性，从而降低了燃烧效率。相对于油的点燃部分的燃烧效率在预期范围内（42-86%）。这表明，当石油压裂导致的可燃性问题得到解决后，牧民将成为石油就地燃烧的有效工具。
The average herded slick thickness, surface distribution and burning efficiency of a light crude oil were studied in ice-infested water to determine the effectiveness of a chemical herder in facilitating thein-situburning of oil. Experiments were performed in a small scale (1.0 m2) and an intermediate scale (19 m2) setup with open water and 3/10, 5/10 and 7/10 brash ice coverages. The herded slick thicknesses (3–8 mm) were ignitable in each experiment. The presence of ice caused fracturing of the oil during the herding process, which reduced the size of the herded slicks and, as a consequence, their ignitability, which in turn decreased the burning efficiency. Burning efficiencies relative to the ignited fraction of the oil were in the expected range (42–86%). This shows that the herder will be an effective tool forin-situburning of oil when the ignitability issues due to fracturing of the oil are resolved.
