The stability of the tunnel face during tunneling is one major criteria for design and construction tunnel. Collapse blowout are two modes failure excavation. cover-to-diameter ratio main parameters controlling these modes. Several analytical solutions have been proposed to estimate range support pressure applied on avoid both collapse blowout. However, most those models deal with homogeneous s...

Understanding and modeling of three-phase transient flow in gas-condensate wells play a vital role in designing and optimizing dynamic kill procedure of each well that needs to capture the discontinuities in density, geometry, and velocity of phases but also the effect of temperature on such parameters. In this study, two-phase Advection-Upstream-Splitting-Method (AUSMV) hybrid scheme is extend...
