... of H 2 and CO 2 . Introduction Geo-storage technologies have been suggested as a method to store and withdraw large quantities of H 2 and CO 2 . The geologic formation is one of the options that provide a large storage capacity. Structural trapping is the primary mechanism that holds H 2 and CO...

... Abstract Gas (hydrogen (H 2 ) and carbon dioxide (CO 2 )) geo-storage is a prominent solution for a low-carbon global economy. Geo-storage formations are very complex in nature and their wetting characteristics are dependent on various parameters. The literature lacks analysis of caprock’s...

... and thermodynamic properties of CO 2 , combined with the effect of ScCO 2 on mechanical properties of shale. The finite element method is used to solve the distribution of formation temperature, pore pressure and stress with time and position. The results show that compared with water seepage, the variation...

... ABSTRACT: CO 2 pre-pad energized fracturing operation was successfully pilot tested in shale oil development. The replacement of crude oil by CO 2 during the soaking period is considered to be a significant factor of EOR mechanism, but crude oil replacement by CO 2 has not been studied...

... ABSTRACT: We explore the impacts of flue gas injection as an alternative to CO 2 injection for geologic carbon sequestration (GCS) and enhanced oil recovery (EOR). To address the increase in pressure-driven risks with increased injection volumes, we create a model comparing subsurface behavior...

... ABSTRACT: Pre injection of CO 2 before main fracturing can effectively increase oil production and store CO 2 . SEM scanning showed that complex cross fracture structure is formed on the rock surface, and the permeability of the core is significantly improved after CO 2 soaking. According...

... ABSTRACT: CO 2 fracturing has been pilot tested to improve the hydraulic fracture complexity of the near-well area in Jimsar thin interbedded shale reservoirs. However, the characteristics of hydraulic fractures created by CO 2 in this reservoir has not been studied systematically from...
