    Abstract

    Oil production methods are classified as primary, secondary, or tertiary processes. Each of these may recover approximately 15% of the available oil in a reservoir. Oxygen fireflooding is a tertiary oil recovery process that uses in-situ combustion to recover heavy oil. Oxygen injection pressures of approximately 6.9 and 20.7 MPa, respectively, are being used in Alberta and Texas to recover heavy oil. This is an application in which the effects of both corrosion and materials flammability have to be considered. Surface and downhole components associated with oil recovery may be relatively complex and have evolved to meet the specific needs of the industry. Materials, systems, and operating considerations that affect the design of surface and downhole equipment for oxygen firefloods will be discussed.
