Steam flooding is an important thermal recovery method for heavy oil reservoirs, and convective heating technology is used to fracture oil shale reservoirs with good results. This paper reviews the main prediction methods, optimization approaches for steam flooding performance, and its application in fractured oil shale reservoirs. The prediction methods include experimental, numerical simulation, and statistical models. These provide insights into steam override, heat transfer, and production dynamics. To optimize steam flooding, parameters like quality, temperature, injection rate, and allocation need to be coordinated based on reservoir conditions and monitoring data. Real-time injection control, economic analysis, and sweep efficiency improvements should also be considered in optimization workflows. Although progress has been made, more field studies are needed to establish systematic optimization practices utilizing advanced technologies. This review summarizes the key developments in steam flooding modeling and optimization, providing a reference for further research and field applications.

1 Introduction

Steam flooding is an important thermal recovery technique that uses heat to mobilize and produce heavy and viscous crude oil. It helps reduce oil viscosity through various mechanisms and improves recovery from depleted or marginal reservoirs. This paper reviews key developments in modeling and optimizing steam flooding performance for conventional heavy oil as well as applications in fractured reservoirs like oil shale. Prediction methods provide insights into complex heat and fluid flow dynamics during steam flooding. Various technical parameters need to be optimized based on reservoir conditions to improve project economics. Convective heating technologies have been applied in fractured reservoirs including oil shale with good results. Further studies on systematic optimization workflows are still needed to maximize the potential of steam flooding (Rao et al., 2022; Xu et al., 2022). This review summarizes progress in this area to provide a reference for future research and field applications.

2 Steam flooding reservoir prediction methods

The main methods for dynamic prediction of steam flooding development are mine-site experimental method (Zhao, 2020), numerical simulation method (Falta et al., 1992; Mozaffari et al., 2013), and statistical model method (Shafiei et al., 2013). The mine-site experimental method mainly summarizes the steam overriding phenomena in the block based on the production situation of the block, combined with geological characteristics, and analyzes some rules of steam overriding (Sander et al., 1991). Lauwerier (1955) was the first scholar to start the theoretical research on steam flooding and make some progress. Through his studies on reservoir heat transfer problems such as injecting steam and other hot fluids, he obtained the laws of reservoir heat transfer in the reservoir and near the injection wells. Langeheim and Marx proposed a classic mathematical model for steam injection and thermal oil recovery by viscosity reduction. This became the theoretical basis for subsequent scholars to study thermal oil recovery by steam. Through Langeheim and Marx’s theory, the speed of heat penetration, cumulative heated area, and the economic limit of injecting heat into an ideal reservoir at a constant temperature rate can be roughly estimated (Marx and Langenheim, 1959).

Ramey (1959) further expanded the above steam flooding theoretical model in 1959. Ramey changed the original fixed steam injection rate to variable steam injection rate, which was Ramey’s major contribution to steam flooding theory. Willman et al. (1961) derived an equation that can roughly estimate the heating radius under a fixed steam injection rate. This method was used to predict the required steam injection rate for a fixed steam volumetric flow rate in radial flow reservoirs.

The research results of the above scholars assume that the temperature distribution in the reservoir is step-wise, dividing the fluid flow regions in the steam flooding process into hot and cold zones. This theoretical assumption was broken by Mandl-Volek (1969)’s innovation on physical models in 1969. The model incorporates heat exchange at the steam front in the steam flooded reservoir, and introduces the concept of “critical time” into the model. Based on Mandl-Volek’s theory, Myhill-Stegemeier (1978) proposed a set of steam front displacement theories through in-depth research. The premise of this method assumes that the oil displacement is equal to the crude oil production. If the calculation is based on this assumption, the results will be biased high.

Through sensitivity analysis of various parameters on the Kern River block, Gomma (1980) established a new steam flooding model. His analysis revealed the relationship between key parameters such as formation thickness, net to gross ratio, and initial oil saturation for this type of steam flooded reservoir. The calculation formula can be used to obtain reservoirs with similar fluid properties or physical similarities to the Kern River block. However, this method is only applicable to reservoirs similar to the Kern River block.

Based on the theoretical foundations of the above models, Jones (1981) proposed a mathematical model for one-dimensional steam flooding. The Jones model combines 3 empirical coefficients from actual field production to predict steam flooding production dynamics. However, the empirical coefficients of this model can only be applied to reservoirs with similar properties to the Kern River field. To apply it to other oilfields, the empirical coefficients must be history matched against actual field data to obtain accurate coefficients.

Considering steam override, Farouq Ali (1982) proposed a steam flooding model based on the Van Lookeren model theory. The most obvious advantage is the use of the principles of conservation of mass and energy. It considers heat loss without relying on empirical data. However, the shortcoming is that some parameters of this model are difficult to obtain, and temperature has a significant impact on relative permeability. Therefore, the experimental results hardly reflect the real situation. To facilitate screening and evaluating reservoirs for suitability of applying steam flooding for improved oil recovery, Aydelotte and Pope (1983) constructed a simplified predictive model for steam flooding. This model expanded the Van Lookeren model and designed a more general computer program.

Neuman C.H. (Neuman, 1975; Newman, 1975; Neuman, 1985) proposed a new model. This model assumes that the steam zone grows vertically and considers steam override. Miller-Leung (Miller and Leung, 1985) divided the reservoir into three zones - the steam zone, condensation zone and cold oil zone, and established a predictive steam flooding model considering steam override. The model established by Torabzadeh-Kumar (Torabzadeh et al., 1990) has standardized the historical dynamics of the same or similar oilfields. However, the relationship between normalized recovery factor and injected steam was fitted using polynomials. Kohei Miura and Jin Wang (Miura and Wang, 2012) proposed a simplified analytical model for predicting cumulative steam-oil ratio during steam assisted gravity drainage process (Figure 1).

3 Steam flooding production optimization

With the advancement of steam flooding technologies for heavy oil recovery, optimizing steam flooding performance has received increasing attention in both academic research and field applications (Alvarez and Han, 2013; Dong et al., 2019). The key objectives of steam flooding optimization are to maximize heat efficiency, improve sweep efficiency, delay steam breakthrough time, and enhance oil production in an economic manner (Kirmani et al., 2021). This requires optimizing multiple technical parameters throughout the entire process from pilot design to late field development (Huang et al., 2018). Recent studies have proposed various approaches to optimize steam injection parameters based on reservoir conditions (Shin and Polikar, 2007). Dong et al. (2019) optimized quality and temperature of high pressure steam injection for a deep reservoir and achieved higher oil rates than normal pressure. Sun et al. (2017) optimized injection rate to balance heat efficiency and oil production.

With the help of monitoring technologies like distributed temperature sensing (DTS), real-time injection control and optimization has become viable. Patel et al. (2018) designed a closed-loop approach to continuously optimize steam rate based on DTS data and simulator predictions. Teletzke et al. (2010) adjusted injector-producer spacing based on monitoring to mitigate steam override issues. These practices have proven effective in increasing sweep efficiency and reducing steam loss.

To address reservoir heterogeneity, steam allocation optimization has been applied. Yan et al. (2018) optimized zone-based steam allocation with a multi-objective genetic algorithm and improved Net Present Value. Such optimization helps utilize steam energy more efficiently. Economic analysis should be incorporated in steam flooding optimization. Kannah et al. (2021) performed economic evaluation on various steam operational strategies. The optimal strategy balances oil rate, heat efficiency and project life to maximize profitability. Economic optimization helps justify optimization practices and improve overall field development value.

Steam quality is the mass fraction of the vapor to the liquid phase (Guo et al., 2022). It represents a dimensionless number between 0 and 1 indicating the amount of water converted to steam. Steam quality affects displacement efficiency as well as viscosity reduction and other mechanisms, which helps determine optimal flooding conditions (Srochviksit and Maneeintr, 2016). Compared to high injection rates, lower injection rates but higher steam quality can increase recovery to a greater extent (Al Shaibi and Al Abri, 2018). Steam optimization utilizes proper steam allocation to increase oil production in a cost-effective monitoring program, while maintenance, variation in steam quality and restricted steam distribution have negatively impacted steam flooding (Castrup, 2019). Based on these studies, a proper and optimized steam injection scheme can be recommended that activates recovery mechanisms by adjusting steam quality and temperature. This research helps select injection schemes that consider the challenges of steam flooding and maximize total field production from heavy oil reservoirs under economic conditions.

In summary, optimizing steam flooding requires coordinating multiple technical parameters over the entire project life based on continuous monitoring and updated reservoir data. More field studies are still needed to establish robust and systematic optimization workflows with the aid of advanced technologies.

4 Application of steam flooding in fractured oil shale reservoirs

An important technique for developing oil shale reservoirs is convective heating technology, which uses high-temperature fluids to heat the oil shale in situ. Several heating and production wells are first drilled in the oil shale formation, and hydraulic fracturing is used to interconnect the heating and production wells (Wei et al., 2021a; Wei et al., 2021b; Shiming et al., 1305). Then the positions of the production and heating wells are alternated periodically. High-temperature fluids are injected into the oil shale layer through the heating wells, heating up the oil shale formation and thermally cracking kerogen to generate oil and gas. The produced oil and gas are carried out to the surface by the cooler fluids or condensed water through the production wells. The cracking and release of pyrolysis gases from the oil shale generates numerous microfractures, which helps improve the matrix permeability of the oil shale and enhance flow channels (Fan et al., 2010). Compared to electrical heating for in-situ development, the in-situ development of oil shale using fluid heating is more complex, requiring consideration of more factors in numerical simulation. These factors include heat transfer, temperature field, pressure field, fluid flow, and the influence of fractures.

Kang et al. (2008) studied in-situ development techniques for oil shale using steam injection heating, and performed coupled analysis of the fluid flow, temperature, and chemical fields. Li (2017) carried out numerical simulation studies on the temperature field, kerogen concentration, and oil production during steam injection in-situ development of oil shale. Based on hydraulic fracturing to connect the injection and production wells in oil shale formations, Wang (2011) performed simulation analysis of steam injection heating techniques for oil shale. The effects of fracture position on oil shale heating were discussed, but only two-dimensional reservoirs were simulated.

Xue (2007) discovered through numerical simulation that using high temperature and high pressure steam can effectively pyrolyze oil shale and carry away the generated shale oil. High temperature and high-pressure steam can also significantly increase the number of fractures inside the oil shale, improving its permeability. Jiang et al. (2015) performed numerical simulation studies on nitrogen gas injection from production wells for heating and heat transfer. Based on extending the functions of open-source fluid simulation software from Los Alamos National Laboratory in the US, Kelkar (Kelkar et al.) carried out numerical simulation studies of coupled thermal-hydrological-mechanical-chemical processes during in-situ conversion and production, and provided some simple simulation examples. Zhao (2013) performed coupled thermal-flow-solid simulations of the interaction processes between oil and gas components during underground co-gasification of oil shale and coal, obtaining the evolution laws of underground temperature fields and coupling characteristics in the co-gasification process. Li (2017) used CMG numerical simulation software to simulate oil shale pyrolysis experiments, designed the model as a dual-porosity geological model. The kerogen decomposition chemical reactions used an alternative reaction mechanism, simplifying the decomposition process into three chemical reaction equations. Based on IFCD technology, Liu (2019) combined experimental research with numerical simulation to summarize the physical property evolution laws of oil shale during heating. The temperature, stress and strain field variations in the oil shale layer during in-situ development were also analyzed.

5 Results

This review summarizes key developments in modeling and optimizing steam flooding performance. Prediction models provide insights into complex dynamics like steam override and heat efficiency. Optimizing parameters such as quality, temperature, injection rate and allocation can improve performance based on reservoir conditions. Real-time injection control and dynamic optimization enabled by monitoring technologies have been implemented. Economic analysis is vital for justifying optimization practices. Convective heating shows potential in fractured reservoirs like oil shale, by thermally cracking kerogen and enhancing permeability. Further studies are needed to develop systematic optimization workflows using advanced technologies. This review of modeling and optimization advances provides a valuable reference for steam flooding research and applications.
