“…To foster a deeper understanding of potentially devastating effects of CO 2 –EOR activities on the ecological systems, regarding the possible concerns of CO 2 injection entail the formation of CO 2 which might enhance the magnitude of permeability especially along faults that allows movement of unwanted fluid and the buoyant nature of CO 2 , which has the capability to rescue from the improperly sealed wells or those wells that are susceptible to CO 2 erosion. In this comprehensive study, the emitted CO 2 could enormously influence local ecosystems based on the magnitude and continuity and it beneficially improves the oil recovery factor due to its high feasibility rather than other methodologies of injection 40‐42 …”

“…In this comprehensive study, the emitted CO 2 could enormously influence local ecosystems based on the magnitude and continuity and it beneficially improves the oil recovery factor due to its high feasibility rather than other methodologies of injection. [40][41][42] Chemically, EOR techniques are considered as efficient ways to improve recovery factor in fractured reservoirs. In this experimental investigation, the simultaneous utilization of nitrogen and foam flooding are explicitly evaluated.…”

To study the profound impact of reservoir characteristics on flow regime in two‐phase condition, the effect of saturation and capillary pressure (Pc–S) should be taken into consideration in the porous medium. The purpose of this extensive experimental investigation is to inject the foaming agent and nitrogen gas, which is produced by the foam generator after waterflooding in a fractured reservoir to select the best optimum scenario. It has been elaborated that nitrogen of lower density and lower compressibility would provide a secondary gas cap at the top of the cores which causes to mobilize more oil volume in the unswept zones. The rupturing of foam considerably influences this phenomenon in the high permeable layers that have led the oil of low permeable layers to be mobilized in the presence of nitrogen.

“…When the injected steam flows into the fracture network, it can effectively heat the formation to reduce its oil viscosity and discharge crude oil more effectively by gravity (Li et al 2019c). Mohsenzadeh et al (2016) conducted a long fracture model experiment, focusing on an oil displacement process under the condition of coinjection of steam and gas. It was found that the coinjection of steam and flue gas under certain conditions can significantly improve the recovery of heavy oil in an experimental model of fractured carbonate rock (Li et al 2017).…”

Carbonate reservoirs worldwide are complex in structure, diverse in form, and highly heterogeneous. Based on these characteristics, the reservoir stimulation technologies and fluid flow characteristics of carbonate reservoirs are briefly described in this study. The development methods and EOR technologies of carbonate reservoirs are systematically summarized, the relevant mechanisms are analyzed, and the application status of oil fields is catalogued. The challenges in the development of carbonate reservoirs are discussed, and future research directions are explored. In the current development processes of carbonate reservoirs, water flooding and gas flooding remain the primary means but are often prone to channeling problems. Chemical flooding is an effective method of tertiary oil recovery, but the harsh formation conditions require high-performance chemical agents. The application of emerging technologies can enhance the oil recovery efficiency and environmental friendliness to a certain extent, which is welcome in hard-to-recover areas such as heavy oil reservoirs, but the economic cost is often high. In future research on EOR technologies, flow field control and flow channel plugging will be the potential directions of traditional development methods, and the application of nanoparticles will revolutionize the chemical EOR methods. On the basis of diversified reservoir stimulation, combined with a variety of modern data processing schemes, multichannel EOR technologies are being developed to realize the systematic, intelligent, and cost-effective development of carbonate reservoirs.

The methods of enhancing recovery of heavy crude oil explore the importance of enhanced oil recovery and how it has grown in recent years due to the increased needs to locate unconventional resources such as heavy oil, shale, and bitumen. Unfortunately, petroleum engineers and managers are not always well-versed in the enhancement methods available when needed or the most economically viable solution to maximize their reservoir's productivity. Various recovery methods have been explored to extract heavy oil from deep reservoirs or oil spills. This chapter summarizes the details of methods, namely nanoparticle technology, carbon dioxide injection, thermal recovery and chemical injection, which include the methodology as well as the findings.
