Summary: Understanding the interaction between rock and fluid is crucial for the success of enhanced oil recovery (EOR). However, the presence of calcium sulfate minerals, such as anhydrite, significantly affects EOR methods. The effectiveness of oil recovery techniques depends on the distribution and interaction between anhydrite and fluids. This review highlights the factors influencing anhydrite dissolution during EOR and discusses the implications for different EOR fluids. It also examines the prospects and challenges of using various EOR applications in anhydrite-containing reservoirs.

Summary: In this study, a CO2-responsive worm-like micelles (WLMs) were prepared using N,N-dimethyl oleoaminde-propylamine (DOAPA) and sodium salicylate (NaSaI). The foam performance, fluidity-control ability, oil-displacement performance, microscopic-seepage law, and microcosmic, demulsification and defoaming analysis of the simulated produced-fluid were investigated. The results showed that DOAPA-H+ increased the viscosity and stability of the foam-based solution under the action of organic salt. The worm-like micelle CO2 foam (DOAPA@NaSaI-H+) enhanced oil recovery (EOR) by 26.2% and 27.3% in homogeneous and heterogeneous models, respectively, which were about 1.5 times that of traditional CO2 foam. The system also achieved rapid and pollution-free demulsification and defoaming after injecting N2 into the production fluid. This research indicates that DOAPA@NaSaI-H+ has great potential for EOR and reducing the difficulty of production-fluid treatment, providing a new idea for combining CO2 resource utilization and storage in low-permeability reservoirs.

Summary: The efficiency of cloisite 30B nanoclay as a foaming agent for CO2 foam stability was assessed for the first time. The results showed that cloisite 30B nanoclay improved the efficiency of CO2 foam, although not as much as silica nanoparticles. Adding 0.1 wt% of nanoclay increased the foam decay time from 30 to 76 min, while the same concentration of silica NPs yielded a foam decay time of about 98 min.

Summary: Foam stability is crucial for the success of foam-field applications. This study demonstrated that a mixture of cocamidopropyl hydroxysultaine and sodium dodecyl sulfate can significantly improve the stability of CO2-in-brine foams, reducing drainage and coarsening. The synergy exhibited by the surfactant mixtures not only enhanced the viscosity-driven stabilization of the foams, but also allowed for the retention of large amounts of CO2 inside the foam.

Summary: The feasibility of N2 alternating CO2 injection for improving CO2 storage and oil production was investigated through laboratory experiments and numerical simulation. The results showed that the N2 alternating CO2 flooding had 2.1% lower CO2 storage factor and 7.1% lower enhanced oil recovery compared to continuous CO2 injection. However, the larger the N2 slug volume, the lower the EOR and CO2 storage factor, due to the reduction of CO2 concentration in the gas phase and CO2 solubility in oil and water. Nevertheless, the N2 slugs significantly reduced mobility differences between flowing zones, resulting in a 1.78 times larger gas swept area and a 44% higher cumulative oil production compared to continuous CO2 injection. Moreover, the optimized N2 alternating CO2 injection scheme achieved 19.6% more CO2 storage than continuous CO2 flooding at a field scale. This study provides valuable experimental and theoretical support for improving CO2 storage and oil production in an oil reservoir.

Summary: To meet the growing global energy demand, the petroleum industry has turned its attention to enhanced oil recovery (EOR) methods. Foam injection, as one of these methods, offers advantages over water and gas injection due to its low sensitivity to gravity and permeability heterogeneities. However, the thermodynamic instability of foams has limited the widespread use of this recovery technique. This study explores the use of nanoparticle-stabilized foams, taking advantage of recent breakthroughs in nanoparticles engineering. The results demonstrate that the addition of silica nanoparticles can increase the stability of nitrogen and CO2 foam, with the extent of improvement depending on temperature, salinity, and optimal nanoparticle concentration.

Summary: CO2-switchable surfactants have selective surface-activity that can be activated or deactivated by adding or removing CO2. They are mainly cationic and can be activated by the protonation of a nitrogen-containing group upon sparging CO2 gas. CO2-switchable superamphiphiles can be formed by non-covalent bonding between components at least one of which is CO2-switchable. So far, CO2-switchable surfactants have been used in various types of colloids such as spherical and wormlike micelles, vesicles, emulsions, foams, and Pickering emulsions.

Summary: This study examined the detailed reservoir characterization of Qadirpur Field Eocene rock units in the Central Indus Basin, Pakistan. Various petrophysical parameters were analyzed, including water saturation, shale volume, porosity, hydrocarbon saturation, and lithology. The study found high effective porosity and hydrocarbon saturation in the Eocene reservoirs, with the Sui Upper Limestone being the poorest reservoir. Secondary porosities contributed to the total porosity, and the reservoirs produced hydrocarbons without water and gas-emitting carbonates. The study also developed methods for evaluating lithotypes and reservoir prospects.

Summary: In order to successfully discover and develop tight sand gas reserves, it is important to locate sand with specific features such as significant accumulation of hydrocarbons, rock physics models, and mechanical properties. However, representing these reservoir properties effectively using applicable parameters can be challenging due to the complex heterogeneous structural characteristics of hydrocarbon sand. Rock physics modeling of the sandstone reservoirs in the Lower Goru Basin gas fields helps establish the link between reservoir parameters and seismic properties, allowing for a better understanding of the characteristics of unconsolidated reservoir sands.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
