A very small risk of catastrophic loss of containment, and subsequent rapid release of large quantities of potentially toxic or explosive gases, exists for offshore oil and gas extraction and reinjection wells. This risk can be minimized by engineering, but planning must address the means to bring such an event under control, while minimizing the risk to people and the environment. Emergency planning and risk assessments for such an event rely on the availability of information about the behavior of released gas, most critically the dissolution and dispersion of the gas underwater and in the atmosphere.

对于海上油气开采和回注井来说，发生围堵灾难性损失以及随后迅速释放大量潜在有毒或爆炸性气体的风险非常小。这种风险可以通过工程来最小化，但是规划必须解决将这种事件置于控制之下的方法，同时将对人和环境的风险最小化。此类事件的应急规划和风险评估取决于所释放气体行为的信息，最关键的是关于气体在水下和大气中的溶解和扩散的信息。
