Studies have shown that carbonate rock dissolution is more pronounced under normal and medium temperature conditions compared to low and high temperatures (Meng et al., 2022). The decomposition of these minerals can occur at relatively low temperatures (400–600 °C), affecting the bonding between the minerals and altering the rock's chemical ...

Dissolution of carbonate minerals has been thoroughly studied in the field of geochemistry. 7−10 It has also been suggested as a mechanism of smart waterflooding in carbonate rocks. 11,12 Dissolution of calcium carbonate minerals may trigger various effects that could facilitate the production of oil.
- Can CO2 enhanced oil recovery be achieved in carbonate reservoirs?
- Challenges for CO 2 enhanced oil recovery in carbonate reservoirs are illustrated. Carbon dioxide (CO 2) enhanced oil recovery (EOR) in carbonate reservoirs is regarded as a promising EOR technology. However, the oil recovery factor of CO 2 EOR is low due to the CO 2 EOR mechanisms in carbonate reservoirs are not clear.
- What is the oil recovery rate of carbonate reservoirs?
- Take China’s Tahe oilfield for example, the oil recovery rate of carbonate reservoirs is only about 15% . A large amount of the unrecovered oil is left after the primary and secondary water injection. The oil production of carbonate reservoirs needs to be boosted in the future to meet the increasing energy demand.
- Does wettability affect oil recovery in naturally hydrophobic carbonate reservoirs?
- Foams are reviewed in detail in Sect. 3.4.3. Wettability is long recognized as an important factor that strongly affects oil recovery in naturally hydrophobic carbonate reservoirs implementing cEOR methods. Wettability is defined as the preferential tendency of a fluid to spread onto a solid phase in the presence of other immiscible fluids.
- Can surfactants improve oil recovery in oil-wet carbonate reservoirs?
- Similarly, use of low-concentration pure surfactants (such as ethoxylated alcohols) in injected water was also seen to improve oil recovery in oil-wet carbonate reservoirs, presumably by enhancing imbibition through wettability alteration and lowering of the interfacial tension (IFT).
