... uncertain. To address this knowledge gap, the present study investigated the dissolution behaviors of both altered and unaltered basaltic rocks in a brine that simulating the real reservoir condition with 5 MPa CO2 gas at 100 through laboratory batch experiments. The experimental results indicate...

... experimental strengths have been utilized instead especially in case of offshore drillings. This is because the core recovery of deep-sea drilling is usually limited and destructive tests such as triaxial compression experiments can hardly be performed continuously with depth. In addition, it is also difficult...
