Summary: Oil reservoirs with hydrophobic surfaces have a significant impact on flow functions at the macro-scale. However, quantitative measurement of CO2 in oil-wet formations remains challenging due to inconsistent experimental data and uncertainties in predicting wettability. In this study, NMR technology was used to measure and analyze the wettability indices in an oil-wet San Saba, providing comprehensive data on the effect of pore-scale properties on flow functions. These findings contribute to the implementation of carbon capture and storage (CCS) and enhanced oil recovery (EOR) projects in oil-wet reservoirs.

Summary: In this study, the effect of CO2 on the mechanical properties of Morrow Sandstone in the Farnsworth Unit oilfield in Texas is investigated. Mechanical compression tests with acoustic monitoring and microscratch tests are conducted on core samples to understand the role of CO2 on poroelastic moduli and fracture toughness. The results show that CO2 exposure leads to a reduction in scratch toughness and a increase in dynamic elastic modulus at the mesoscale. The grain orientation also affects the CO2-induced geomechanical alterations, with a greater decrease in fracture toughness observed in the bedding-perpendicular orientation.

Summary: This study evaluates CO2 adsorption under pressure and temperature conditions for geological storage in two non-shale reservoirs in Canada. The results show that CO2 adsorption can substantially increase storage capacity and decrease leaking potential by reducing overpressure in the reservoir caprock. The adsorption behaviors of rocks from different reservoirs are distinct, and CO2 can enter small rock pores to enhance adsorption and utilization of reservoir capacity.

Summary: The study investigates the feasibility of storing CO2 inside hydrate stability zone (HSZ) through reservoir pressure management via water producers and CO2 injectors. Results show that by controlling reservoir pressure, CO2 can be stored in HSZ with the formation of CO2 hydrate delaying CO2 breakthrough and limiting gas leakage.

Summary: CO2 flooding is an important technology for enhancing oil recovery and efficient CO2 storage. However, gas channeling and low recovery are common challenges due to poor reservoir properties and unfavorable mobility ratio of CO2. Chemically assisted CO2 thickening technology has been developed to control gas flow rate and improve CO2 repulsion effects. By evaluating the effect of CO2 viscosity enhancer composite system on oil drive under different conditions, it was found that the system can effectively improve recovery rate.

Summary: This study aimed to investigate the convective mixing of CO2 in oil phase under simulated reservoir pressure and temperature conditions. Experiment results showed that the CO2 transport rate in n-decane increased with the Rayleigh number, while the overall pressure decay was faster in n-decane compared to crude oil, leading to a breakthrough time three times slower in crude oil than in n-decane.

Summary: The recoverable hydrocarbon reserves of conventional oil and gas resources are limited in China, making unconventional oil and gas an important research focus. Tight reservoirs have the potential to alleviate the increasing demand, but issues such as rapid pressure depletion and low productivity arise due to poor physical properties. CO2 flooding can enhance the development of tight oil, but precipitation and dissolution affect pore structure evolution and oil displacement efficiency. Attention should be focused on fractures, solid-liquid interactions, and the quantitative evaluation of pore structure evolution and interaction strength.

Summary: This research focuses on characterizing reservoir properties using rock physics and AVO analysis, followed by pre-stack inversion. Two approaches are investigated: one utilizing well and seismic data, and the other utilizing only seismic data. The first approach involves well-log cross-plots and AVO analysis to determine feasibility and pay zone, followed by pre-stack inversion for predicting porosity and gas saturation. The second approach involves generating synthetic seismograms and synthetic well logs for predicting reservoir properties. The results are validated using real well data.

Summary: Research has investigated the complexities of seismic reflection/transmission problems in various porous materials described by poro-viscoelastic theories. It has been shown that even simple plane waves at plane interfaces between different isotropic viscoelastic solids are more complicated than initially expected. Further study is needed to address the difficulties in accurately selecting the signs of vertical slowness vectors in order to calculate R/T coefficients without unphysical discontinuity.
