As a highly important preliminary step to ignition, consideration must be given to the desirable ignition points for a particular formation. The main factor to consider is which section or sections of the formation should be ignited to realize maximum oil recovery from the project. Once this is decided, the injection well completion can be designed. The injection well must be completed so that air enters at the selected point, and the well must be properly cemented to confine the high-pressure air to the formation or zone ignited. Wells have been successfully ignited through perforations, open-hole, slotted liners, gravel packs, and through tubing set on conventional packers. Where the reservoir is not susceptible to spontaneous ignition, artificial methods must be used. The many different techniques that have been used include surface heat injection, chemical methods, and downhole heaters. Electrical heaters and gas or liquid-fueled burners are widely used for ignition purposes. Both electrical and gas bottomhole heaters are described.
