..., concentration gradients develop radially. Introduction Living in the 21st century is one of the best eras that humans have experienced while they roamed the Earth. Thanks to a huge series of technological advisements that made our live much easier that ever. We live in an era where carbon is involved...

... flow, heat transfer, and species transport. Considering the influence of the heat transfer, the multiple governing equations are coupled to simulate the construction process of the 3D horizontal salt cavern. The influence of heat transfer on fluid flow, brine concentration, and cavity expansion...

... at the breakout tip which attracts the highest stress concentration. The newly derived maximum horizontal stress estimation model is validated based on several sets of laboratory borehole breakout experiments conducted under three-dimensional stress conditions sourced from literature. Comparison between the model...

... wettability turned from Intermediate to strong CO 2 -wet mainly due to the increase in organic surface concentration and pressure. The higher the alkyl chain length of organic acids, the higher the hydrophobic conditions for mica substrates. Alumina nanofluid has shown great potential to reverse...

...-120 mesh: 180-200 mesh=1:2:5.2, and a thickness of 16cm can meet the pressure holding requirement of 10 MPa. It is recommended to use the low-viscosity slick water to inject the BA with the injection rate of 3-5 m 3 /min, and the concentration should be controlled at around 5 %, the pump only needs...

... of proppant concentrations in the wellbore is the main reason for the un-equilibrium partitioning of the proppants among the clusters. The sensitivity analysis shows that the un-equilibrium partitioning of the proppants by optimizing the pumping rate, proppant sizes and densities. Our study results can...
