Size distribution of oil droplets formed in deep water oil and gas blowouts have strong impact on the fate of the oil in the environment. However, very limited data on droplet distributions from subsurface releases exist. The objective of this study has been to establish a laboratory facility to study droplet size versus release conditions (rates and nozzle diameters), oil properties and injection of dispersants (injection techniques and dispersant types). This paper presents this facility (6 m high, 3 m wide, containing 40 m(3) of sea water) and introductory data. Injection of dispersant lowers the interfacial tension between oil and water and cause a significant reduction in droplet size. Most of this data show a good fit to existing Weber scaling equations. Some interesting deviations due to dispersant treatment are further analyzed and used to develop modified algorithms for predicting droplet sizes in a second paper (Johansen et al., 2013).
在深海油气井喷中形成的油滴的大小分布对油在环境中的命运有很大的影响。然而，关于地下释放的油滴分布的相关数据非常有限。本研究的目的是建立一个实验室设备，研究油滴大小与释放条件（速率和喷嘴直径）、油的性质和分散剂的注入（注入技术和分散剂类型）之间的关系。本文介绍了该设备（高 6 米，宽 3 米，包含 40 立方米海水）和初步数据。注入分散剂可以降低油和水之间的界面张力，导致油滴大小的显著减小。这些数据中的大部分都与现有的 Weber 比例定律方程很好地吻合。由于分散剂处理的一些有趣的偏差，进一步进行了分析，并用于在第二篇论文中开发预测油滴大小的修正算法（Johansen 等人，2013）。
