“…Comparable efforts, such as Rojas et al's [86] pioneering work, have introduced a concise three-step reaction scheme that adeptly replicates the ignition process, temperature profiles, combustion velocity, and fluid production. This scheme holds promise for its applicability in the scaled-up simulation of in situ combustion scenarios.…”

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.

The demand for fuel from unconventional sources is increasing all over the world, however, there are still special and strict regulations regarding the methods of enhanced oil recovery as well as the content of the oil produced, including the amount of sulfur. In-situ combustion (ISC) is an attractive thermal method to enhance oil recovery and in-situ upgrading process. In this work, copper (II) oleate and copper (II) stearate were used for the oxidation of extra heavy oil with high sulfur content in the ISC process using a self-designed porous medium thermo-effect cell (PMTEC) and visual combustion tube. Using PMTEC the catalytic performances of the synthesized oil-soluble copper (II) oleate and copper (II) stearate and kinetic parameters such as activation energy using Ozawa-Flynn-Wall method were studied. The X-ray diffraction (XRD) and high-resolution field emission scanning electron microscopy were used to examine the characteristics of in-situ synthesized CuO nanoparticles during oxidation. As shown, the presence of oil-soluble copper (II) stearate and copper (II) oleate reduced oil viscosity from 9964 to 8000 and 6090 mPa˙s, respectively. Following ISC process in porous media in the presence of copper (II) oleate, the high sulfur extra heavy oil upgraded, and its sulfur content decreased from 10.33 to 6.79%. Additionally, SARA analysis revealed that asphaltene and resin content decreased in the presence of oil-soluble catalysts. During the oxidation reaction, homogeneous catalyst decomposed into nanoparticles, and heterogeneous catalyst is distributed uniformly in porous media and played an active role in the catalytic process. It should be noticed that, these kind of oil-soluble catalysts can be novel and highly potential candidates for initiation and oxidation of extra heavy oil in order to decrease the viscosity, enhanced oil recovery and production of the upgraded oil.

Considering the global drive towarrd net-zero carbon emissions in the near future, the need to find clean sources of energy has never been more important. It is estimated that globally there are tens of thousands of depleted and abandoned oil fields that may be adapted to produce green energy. These may be re-cycled with the help of air injection, either from the production of hydrogen, as a direct result of oxidation of oil, or the exploitation of the inherent increase in heat flow and pressure via enhanced geothermal systems. In the past, the use of in-situ combustion (ISC) and high-pressure air injection (HPAI) have experienced many failures, largely due to poor project design and inappropriate reservoir selection. Here, we review data from field applications, experimental studies, and numerical modelling to define the roles of sub-surface sedimentology and petrophysics, structural geology, geomechanics, mineralogy, diagenesis, and petroleum geology on the success of ISC and HPAI. We show how current knowledge can help mitigate project failure via improved project design and initial reservoir selection. Improvements to the design and implementation of ISC and HPAI projects promise to allow the utilisation of the many abandoned oil fields, to produce green energy with the added benefit of the cost-effective, and materials and energy efficient, re-use of existing oil field infrastructure. We conclude that the integration of field data, laboratory experiments, and numerical modelling methods previously studied can be used to help develop ISC and minimize risk of failure.
