Impact of pressure and temperature on CO2-brine-mica contact angles and CO2-brine interfacial tension: Implications for carbon geo-sequestration
TLDR
It is concluded that for a given storage depth, reservoirs with lower pressures and high temperatures can store larger volumes and thus exhibit better sealing efficiency.About:

CO2 wettability of caprocks: Implications for structural storage capacity and containment security
TL;DR: In this article, the authors demonstrate that caprock can be weakly water wet or intermediate wet at typical storage conditions; and water wettability decreases with increasing pressure or temperature, thus, a lower storage capacity can be inferred for structural trapping in such cases.

Current understanding of shale wettability: A review on contact angle measurements
TL;DR: In this paper, a review reveals that while shale is oil-wet in presence of air when compared to water (oil contact angle is much lower than water contact angle in air) based on contact angle measurements, it is preferentially waterwet when converted to hydrocarbon/brine/shale system using Young equation no matter what composition shale has or what type of oil or brine is used.

TL;DR: A method for estimating the effective contact angle, which quantifies the wettability and controls the local capillary pressure within the complex pore space of natural rock samples, based on the physical constraint of constant curvature of the interface between two fluids.

A Guide to CO2 Sequestration
TL;DR: In this article, the advantages and disadvantages of different methods of carbon sequestration are discussed, and the authors conclude that in the short and medium term, carbon capture and storage would almost certainly be cheaper than a full transition to nuclear, wind, or solar energy.

Pore-throat sizes in sandstones, tight sandstones, and shales
TL;DR: Pore-throat sizes in siliciclastic rocks form a continuum from the submillimeter to the nanometer scale as mentioned in this paper, which provides a useful perspective for considering the emplacement of petroleum in consolidated siliclastics and fluid flow through fine-grained source rocks now being exploited as reservoirs.

Impact of relative permeability hysteresis on geological CO2 storage
TL;DR: In this article, the importance of accounting for CO2 trapping in the relative permeability model for predicting the distribution and mobility of CO2 in the formation has been evaluated, and it is shown that the mechanism of capillary trapping can be exploited to improve the overall effectiveness of the injection project.
