The forward method was implemented in a commercial reservoir simulator, and was exploited for time-lapse history matching in which the number of parameters first were reduced using gradzone analysis (Bissell, 1994), and a Levenberg–Marquardt approach was utilized for solving the nonlinear least squa...

seismic wavevelocities continue to increase with depth and no discontinuities are recognized until the D″ zone at the base of the mantle (Fig. 1.2). However, seismic tomographic studies have shown that various “velocity domains” exist in both the upper and lower mantle, and resolution of ...
The solid-melt medium in the depleted upper mantle was mainly an accumulation of garnet and peridotite because the heating effect of lithosphere was relatively weakened in the later riftogenesis, so that a lens-shaped high-density and high-velocity zone was produced in the upper mantle. The ...
