Upstream oil and gas operations, such as drilling of oil and gas wells, well workovers, cleaning and stimulation, petroleum separation and processing, and air injection-based improved oil recovery (IOR), may involve air or an oxygen-containing gas in the presence of hydrocarbons. In such operations, air or oxygen containing gas may be introduced either deliberately (as a part of the process) or undesirably (due to the nature of the operations). Therefore, when an ignition source is also present, there is a potential for fire and/or explosion hazard. Over the past several years, there have been a number of serious oilfield fires and explosions that have resulted in worker injuries and fatalities, and significant loss of equipment. During this same period, there has been an increase in the use of air or oxygen containing gas during such operations in Canada and worldwide. While regulations exist with respect to explosive hazards, there are no clear industry guidelines dealing with air-hydrocarbon mixtures in these well-site operations. This is mainly due to the lack of fundamental understanding of the complex ignition processes associated with such operations.

油气上游作业，如油气井钻井、修井、清洗和增产、石油分离和加工，以及基于空气注入的提高采收率（IOR），可能涉及到存在碳氢化合物的空气或含氧气体。在这种操作中，可能有意（作为过程的一部分）或不希望（由于操作的性质）引入空气或含氧气体。因此，当点火源也存在时，存在潜在的火灾和/或爆炸危险。在过去的几年中，已经发生了许多严重的油田火灾和爆炸，导致工人受伤和死亡，以及设备的重大损失。在同一时期，在加拿大和世界各地的这种行动中，使用空气或含氧气体的情况有所增加。虽然存在关于爆炸性危险的法规，但在这些井场作业中，没有明确的行业指南来处理空气-碳氢化合物混合物。这主要是由于缺乏对与此类操作相关的复杂点火过程的基本理解。
