In Situ Combustion: A Comprehensive Review of the Current State of Knowledge

Abstract

In situ combustion or fire flooding is a promising enhanced oil recovery (EOR) technique designed to produce heavy oils and bitumen. This method involves the in-place heating and combustion of hydrocarbons, resulting in reduced viscosity and increased mobility for improved flow toward the production wellbore. Despite its potential, widespread commercial implementation of in situ combustion has been hindered due to technical and economic challenges like inadequate project design and improper reservoir selection. This literature review paper provides a comprehensive overview of the current knowledge of in situ combustion by addressing its principles, historical development, combustion processes, underlying kinetics, and testing methods. Additionally, the review tackles existing gaps in the literature, as well as the challenges associated with modeling and implementation in field applications. It also suggests solutions drawn from historical field experiences of the technology. Finally, the review paper proposes comprehensive screening guidelines derived from various literature sources for the implementation of in situ combustion. This framework underscores the technique’s potential for efficient and sustainable hydrocarbon extraction, shaping its future as a transformative enhanced oil recovery technology.

In-Situ Combustion for Heavy Oil and Oil Sands Recovery: Recent Progress, Field Applications, and Future Perspectives

“…The temperature in this zone is determined by the operating pressure and the concentration of combustion gases. The edge of the steam zone is the primary area of oil mobilization, where temperature is slightly higher than that of the native reservoir. − This process is defined as dry combustion because only air- or oxygen-containing gas is injected into the reservoir. Figure displays a classic schematic of a dry forward ISC process and each characteristic region.…”
